By having the heater air inlet on the outside of the building you are causing positive pressure inside the home stoping cold air entering through the gaps
I installed one of these under the stairs inside the house with just the exhaust going outside (fuel tank outside!). It has already done 3 winters and has been a blessing with only a log burner in the house for heating. It gets the whole house (small 3 bed) up into the 20's and very comfortable in no time. We now only use the log burner in the evenings since having this even in sub zero winter months.
Ducted warm air systems were very fashionable back in the 70s over here in the U.K. for smaller houses but didn’t really catch on as some customers complained that the warm dry air caused them to have dry raspy throats. Eventually houses went back to wet rad systems on a gas boiler. They are now also on their way out (2026) for new builds to be replaced by electrostatic heating and ground source heat pump systems. (No gas in new builds after that)..
What a load of shite , you need to do some maths , one litre of oil can only produce 10 kw of heat total maximum at 100% efficiency , oil costs £1.60 pet litre , so if your 5 kw heater is 100% efficient it would cost £0.80 pence per hour to run !! Not £0.12 pence as you say the real problem is that your heater is only 80% efficient so the real running cost is £0.96 pence per hour , or to put it simply £24 per day approximately!!!!!!! Unless your heating a 4x4 room up . With a thermostat to switch it off for 23 hours , you are totally conning people who really cannot afford to put there heating on let alone afford to buy install or run a pice of shit that is designed to heat a lorry cab , just a thought if your that tight and you cannot afford your gas bill why not sell that posh house and down size you prick 🤔
Yes!!!!!! I’m so glad someone else has done this and put it up on UA-cam !!! Iv done this and I havnt put my heating on once! 15l tank has lasted 2 months and iv got 4l left , Iv also put it through my dryer vent so I didn’t have to core drill my house
I've got a 2kw diesel heater in my camper van & another one in my double garage sized workshop. Will look into a larger one for the house . Proper game changer. Great upload 👌
I drilled a small hole in my wall and put the exhaust in to the house. I am really impressed with the heat coming out of it. I will check the fuel level in the morning.
What a great video!!!! I’ve been heating my flat this way for the past two winters, It’s saved me 1000s apon 1000s overall and it’s actually very efficient and instant heat. A full tank lasts two days on lowest setting, my “electric” panel heater’s cost about £12 each on a cold day, I have three of them, normally looking at about 20-30 quid a day for electric. A full tank on the diesel costs about £10 for two days!! It pays for itself in just a month! I like how this guy has built a permanent outdoor box, that’s impressive and sensible. Mine is indoors and may save some diesel with recirculating air, however I’d rather clean air coming inn especially inn the autumn. Don’t buy this if you have no idea on combustion or flues. This outdoor box invention really is a good idea! so glad I spotted this video…..thanks for sharing!
What a brilliant idea Mark, had seriously looked at one of these a couple of years ago to replace my Carver heater in my old motorhome, never thought about using it this way, pure genius, methinks this is the answe to helping heat my old (1927) 2 bedroom end-terrace house, thanks for sharing 👍😃
I might have to look into getting one of these as an alternative to lighting the fire during the day when Im home. My house was built in the early 1700's. When it gets cold. its 2 jumpers, woolly hat and a coat on cold.
This unit was designed for boats and works really well I have a 42 ft sailing yacht the heater is in the back of the yacht and has been chucking out heat for 20 years! and is ducted from front to back quiet efficent and very very warm even with snow on the decks. the hosue is a walk in the park to do.
Good to see some one thinking outside the box When i saw these on youtube my first thought was how to use in my hous you my friend have hit the nail right on the head Well done Really well done sir !!!!!!!!!!!!!!!
As an engineer that has installed two diesel heaters in my house, you have explained this soooo well. Better than anyone else on the internet. They give brilliant background heat. Some installations on UA-cam are so clumsy, and look dangerous. Well done Sir.
Great video. Just a little tip, I saw this on a US video, the exhaust baffle should be level and the little opening in the centre/bottom is to allow moisture out condense and drip out. Currently, you’re gathering water in the bottom left side of it. The rest of the exhaust should be level not facing up. Hope this helps!
Great tips. I will also add to have the exhaust even further away. The reason is that your setup is in a corner, so the wind could create a mini tornado and the fumes going to the intake. This has been seen more than once at dive centers with a bad compressor installation and they filled scuba tanks with toxic fumes. And if the wind comes from the right, it'll push back the fumes to the intake as well since the turbulence will spin in the corner.
I don't know much about anything - but wouldn't you want to insulate the hot air outlet so that you don't instantly lose heat? And if the "cumbustion" air is hot, wouldn't you want to coil it round the hot air outlet for the length of which it's still hot? (or around the air intake to pre-heat the air a bit) Does the temperature of the fluid affect the performance? In that case you might want to insulate that as well.
I understand what you mean but just for clarity. In old houses earth under a wooden floor doesn't transmit cold into the house. The heat from the house transfers to the cold area under the floor. Heat energy always transfers from a hot area to a cooler area. I had a lot of trouble with this so I temoved the floorboards, insulated beneath them and replaced the floorboards. This took some time but it made a massive difference to my heating bills and to our living comfort.
You're right but, the house remains cold...that was the point. The heat at the floor is always colder in Victorian houses because heat rises. The top of the room heats up first and it takes a lot more energy for the heat to get to the bottom of the room.
Very nice installation! I am testing my diesel heater which had been sitting in a box for a year. I put it inside the house clamped to the top of my fireplace wood stove insert. I drilled and tapped a 3/4 inch pipe thread hole into the wood stove and the corrugated exhaust pipe fits the hole perfectly. The unit is powered by a 12 volt lithium battery pack that I built a few years ago. It will power the heater for 17 hours on a single charge if the power goes out again. I have a central natural gas furnace, but it will not work without the utility grid power. In my area, the temperature inversion layer sometimes holds smoke down low, and the Air Quality District forbids the burning of fireplaces in those conditions. With the grid down, the diesel heater will be employed. Exhausting the diesel heater into the wood stove eventually warms the stove top but also provides enough updraft in the brick chimney to draw combustion gasses out. A stick of burning incense showed the smoke being drawn into the wood stove lower intake such that no diesel exhaust will enter the house. The diesel burner keeps the living room at a comfortable temperature of 88F, 20C, with the central furnace shut off. I burn about 3 liters a day of diesel on the H2 and H3 settings. The central furnace burns about $12 of natural gas a day to maintain 62F, 17C, but 3 liters of diesel costs me $4 US. In 4 days of testing, refueling was a concern until I found a plastic 5 liter fuel jug with a push button fill spout. I keep a towel handy but so far, the spout does not spill a single drop of diesel.
You can optimize it more, by elongating the fresh air pipe and adding another one, with a bigger diameter, over it and redirect the exiting combustion air in the chamber between the 2 pipes. The same should be done with the inlet combustion pipe. In this way you are using the combustion air temperature to preheat the inlet fresh air as well as the inlet for combustion air.
When I get mine I will like set it up with internal circulation (for simplicity). However after a welding course I'll make a box to mix the fresh/hot flows like you said - seems like a good compromise. Also looking at extending the exhaust down the wall and through my electrical cabinet - it is big and contains my plumbing; this way as the pipe passes through it can keep that cabinet warm with the waste heat. At about -6.6C my water inlet freezes up so this would be a useful secondary feature, albeit not used often.
Maybe worth pointing out that a 5kw heater like this might not be enough for an old draughty Victorian house as you say but if you have a reasonably modern, open plan house, well insulated and are happy with room temps a bit lower this could be used in isolation
this is awesome. i live in an area with an extreme air pollution. using "fresh air" from outside would be risky. in my loft, i installed a high performance air filter. DIY myself from scratch. 50m3 per hour dual hepa and activated carbon cylinder handled by 100mm RAM fan and ducting system. that lowered the in house smoke pollution from seriously dangerous levels to negligible. i think that both the diesel heater and the air filter could work in combination.
They are sorted Mark well done. We have one in our garden shed bar. Top tip though Mark, make sure your ambient air inlet comes from inside the house. You will have trouble in winter where the ambient air will get too cold and prevent the burner from running at full temperature and fouling up and shutting down, which then often requires a strip down 😉👍
Unless your mechanical minded person you will find it difficult to keep it running I used the webasto water and air heater for 20 years although they been around for 30 years it would be one off the best however if you had to pay everytime it stop it would cost a fortune if you use diesel it will block up with soot and need strip down and cleaned at least once a year best to use kerosene it much cleaner and cheaper under 1 pound a litre uk service every 2or 3 years ps when we used then in camper van we got nothing only complaints to do with fan noise and the constant ticking off the fuel pump however this may not be the case here as the unit is out side the house however the down side to that is it outside when it needs refueling or service plus the damp which they don't like however it is Chinese and fraction off the price webasto which it was poorly copied off and maybe spare parts could be hard to get I'm just making some facts known before everyone rushes to eBay as the excitement could be short lived also these heater were never intended to run all-day every day (keep warm )
I'm currently planning to build a tiny house for next summer (2023), and I had this alternate heating source in mind. I even already bought a fuel tank, brand new, from a thrift store the other day!
I have installed 2, there's a way to replinsh the heat from the exhaust by using an egr from a diesel car and running a pump with water, or antifreeze straight into a radiator, that way you are utilising 100% efficiency from the heat produced
@@leeyo5494 EGR would imply that the exhaust gasses are recirculated into the combustion air to burn off any remaining hydrocarbons. However it almost sounds like they are recirculating the exhaust gasses through an air to water intercooler to dissipate the heat from the exhaust, and convert it into additional heated air.
I fitted one in my home workshop two years ago. At that time red diesel was 69p a litre. Last year it was 99p now it’s 1.35! It’s getting more and more expensive to run them but still far cheaper and more efficient than electric. Mine is a 5kw and over 8 hours it uses a shade over 1 litre of fuel. Currently costing 17p an hour to run. Two years ago it was 8.5 🥹 Recirculating the air won’t make it run more efficiently or use less fuel but it will mean the outputted air will be slightly warmer but it will be negligible.
We are on the same page with this idea Mark, I've got a LPG tank to go in my Ford transit Custom which I could run a Propex in the same configuration. You can go 'Off Grid' if you have enough Hate about the current Energy Crisis, as I have. I'm prepared to sleep in the Living Room because I can't let these bastards win.
The way you have it installed is probably the most inefficient way to do it, it will not be very effective in really cold weather. Recirculating would be just one step in the right direction. This heater has to be located inside the space you're heating in order to be efficient, only with exhaust and burner intake going outside. Ideally in some adjacent space like the basement or utility closet and air in/out vents going to the main space you're heating.
Your absolutely right Mark, it won't heat the whole house, I've just done a similar install to you but I've placed my heater in my cellar and vented the exhaust outside, then run the hot air pipe through the floor, and under my kitchen floor units, to act like a plinth heater fan. To be honest I'm a bit disappointed, it's not as good as I'd hoped at heating my kitchen/ dining room, and it certainly won't heat the upstairs as well, I think some of the other videos on UA-cam with people saying they can heat the whole house are stretching the truth slightly. They certainly help but they are not a replacement for your central heating system.
I have two, one is a 2kw (for one room) and the one in this video is a 5kw. It won't heat the whole house, as you say but, maybe a 5kw will do more for you.
@@MarkIansonProperty it is a 5 kw that I've got it's an old Victorian end terrace house that I'm renovating, so at the moment it's not the best insulated. This will improve in time, so performance may improve, but at the end of the day they're not meant to heat houses. But every little bit helps, I have a log burner too, so it's not too bad. Plus gas boiler when I absolutely need to use it. I thought about putting a diesel heater in my loft, and venting hot air through the landing ceiling but I'm not too sure how safe that would be? It's the upstairs that gets coldest.
another top tip. Route the exhaust pipe through an old empty radiator. There's still plenty heat in the exhaust gas and you can use it. Bumps your effiency from 65% up to higher than 90%
Bad idea. You want free-flowing exhaust on these so they burn efficiently, also if you are talking about running the exhaust inside through radiator and then back outside that is just asking for carbon monoxide poisoning.
@@moretrash4you Not necessarily correct. If you use a small fan downstream the radiator, that can completely made to balance out the flow restriction of the radiator. Also you can handle the CO poisoning by 1. Having a tight system - you are normally not having water seeping out of your radiators and piping do you? 2. Have a CO alarm to warn if the unlikely happens.
Absolutely brilliant video. This is the best in home install I’ve seen and I’m inspired! Few questions - could/would you put up a link for where you bought the green box from? Also you seem to have your heater in a suitcase inside the box. Is that something else you added, or did your heater come in this box? Finally, cavity insulation, did you have to do anything to remove the insulation from around the hot air inlet into the house! We are struggling like crazy with the rising cost of keeping warm. I have installed one of these in our camper and two in a couple of old VW beetles. Seems the next natural step for me to install it in my house !
My house is sold wall, so no cavity to go through. The Hcalory comes in a box already, the outer green box is from eBay branded as an Amazon parcel delivery box
Over a year for mine Mark. Mine sits inside house but fuel intake and exhaust sits outside. Cold this evening but 23 degrees in here. I do have central heating but rarely use it. My air intake taken from inside. I get your point about fresh air but heater will be very inefficient sucking in freezing cold air in winter. Mine HAS replaced my central heating but you do need to leave all interior doors open.
Just curious how this is beating the cost of living? I understand that having these heaters in cooler areas of the house can provide a comfort convenience. But when factoring in savings on primary heat while running this supplemental heat, is it actually cheaper? Here in Canada I believe natural gas is quite cheaper than diesel. Can you share your cubic meter and per litre prices for gas and diesel? Great video by the way, I like the idea of experimenting with different fuel sources and setups. We are $0.0979 per cu M $0.0923 per KWh And currently $2.08 per L of diesel Diesel is usually between $1.60-1.90 per litre. Thank you
I believe whenever possible the cheapest and more environmentally friendly options is geothermal, as long as you have a backyard it is possible to do it on a moderate budget. After that I'd say solar, and on a third place natural gas.
@@S99-c5s how is it no cheaper? the installation costs if it’s a DIY project are quite affordable, and maintenance is extremely low. Other than that the energy itself is free, it naturally uses the differential of energy accumulated in the underground.
@@S99-c5s take a look at this guy, ua-cam.com/video/xc_BbbMi1cg/v-deo.html everything is very well detailed in his videos, he’s definitely not lying. There are running costs because he’s using a heat pump, still it’s way lower than a conventional AC unit because it’s taking advantage of the free energy on the ground, and you can offset it with solar (like he does). I suppose with an even more efficient system (bigger loops, very well insulated house) you could entirely offset the heat pump running cost or with a fully “passive” system you could entirely go without heat pump thus reducing running costs to virtually zero.
Everyone's an expert, and everyone's got an opinion - but...from other sites, it would help if the unit was high enough for you to avoid putting the exhaust pointing up anywhere. Apparently, you can get a build up of moisture in the bottom bend. Excellent idea and video - I'm doing this once my heater arrives.
Your 24 or 30kw boiler is mostly devoted to hot water production if it is a combi. If you have a small maybe 6 -8 radiator house then the heating part of that might only be 10-15, call it roughly 1.5 per rad.
Nice1 mate, i did this a While back, you want to beat Costs, this is the only way. Heat pumps are rubbish, so is Solar, as is wind power. Eco friendly my arse. I have a diesel heater in the Loft of the garage, keeps the sports car Warm, as well as the house. Top job. Nice video. 👍
NOTE!!! I have a Chinese diesel heater and whilst they are very good and economical there is one major flaw with them and that is they should come with a battery back up in case of power failure. The reason I say this is when you turn the heater off it take about 5 mins to wind down and within this time the fan continues to run. If the power is shut off at the mains or there is a power cut then the fan stops and the heat stays inside the unit and could be a fire hazard.
@@lise1255 maybe 10 watts to run the fan and 100 watts on initial start up for a minute or two. I doubt you'd even notice a change to your electricity bill. As for the power cut issue just run it off a leisure battery and keep it topped up with a trickle charge.
I've got a model that goes up to 8kW. The fuel pump doses 0.02ml per cycle, so at the fastest speed (5.5Hz/cycles per second) it uses 0.02 x 5.5 x 60 x 60 = 396ml per hour. Red diesel currently costs £1.30 in my area, so £1.30 divided by 1000ml = £0.0013 per ml, times our 396ml in an hour = £0.51. Divide that by 8 to get a single kilowatt = £0.06 per kilowatt hour. 6p per kW/H is very attractive in comparison to 35p per kW/H for electricity or 10.3p per kW/H for gas. Of course we have the additional electric cost of powering the heater, which is high on startup but drops during use.
None of that stacks up. Total energy in 1 litre diesel is 10kWh - and that's if you can burn it with 100% efficiency. So it it costs £1.30 a litre, and you reckon it only gets through 396ml an hour, the maximum the heater can be outputting is 3.9kW.
@@GaryMcKinnonUFO Maybe you shouldn't believe it really produces 8kW. Fred's data and math is correct, so something in your data must be wrong, that's probably the 8kW. And you can't burn with 100% efficiency, a lot goes out of the exhaust, so that 8kW you are using is probably closer to 2kW.
Mains gas currently 16p per kWh, plus Vat. Diesel nearly 10 kWh per liter or 20p per kWh with fuel at nearly £2 per liter. No standing charges with the diesel heater.
There is more to it than that. Localised heating. Reduced fuel flow rates possible. Oil can be stored. Not all are on a gas main. There is a price for the electric to run the heater.
@Spirit - you are correct: 1Kwh produced from diesel does indeed cost 20p. How can anyone therefore hope to run a 5Kw heater at full chat for 12p an hour?
A lot of people are now sneaking these into their everyday life and using them for the home. I say fair bloody play to you all! I have 2 in my workshop, 1 in my utility area as thats not heated and a portable one for the summer when on the patio having a beer in the evening especially, when the missus is chilly, she loves it! So yes, I have 4 and they work faultlessly.
@@CharlesPiston Yes, it burns hotter (which is great) but doesn't have the lubrication properties of Diesel. (some will argue) You can suffer early pump failure and this has happened to my neighbour that has a small canal boat but that said it took about 2 yrs to happen and that was running on pure kerosene. So I use a 50/50 mix and have done for 9 months now and I have had no problems so far. hope this helps.
Had plans to do this for a while, But not owning the property i thought i would have to put outside, But wasn't sure it would be good enough. Now i will un pack one and build a box.
I'm using a 8kW diesel heater to heat my small condo - I ended up using about 5 gallons US in 10 days, about $30.00 US, which means it will cost about $90.00 US a month to heat my condo. I only have electricity for heating (no natural gas lines in our old building), so this little diesel heater is far more economical to run. It will even run off one of those solar battery power systems and is portable enough to use for winter camping - no wood stove in the tent! The only thing different in my set-up is I have the fuel line running directly in to a 5 gallon fuel can.
Your 8kW heater does not exist, if it is of the cheap chinese variety. It would need about a litre per hour for 8kW. Your 5 US gallons is 20 litres. Ten days is 240 hours. Go figure. They are not even 5kW output, actually, so might last 40 hours at full tilt. I don’t disagree with your costs, just the real size of your heater. Let’s not exaggerate how good they are on fuel. S litre of diesel only contains about 10.5kWh of energy.
You could plum the could inlet into the house and a have a tapping on the inlet to allow fresh air in as well..sort of a T piece. It would be more efficient and still give fresh air in. can you put a link to the diesel heater you use?
Do you have a link for purchase of the whole set up you have , including the box . Great video btw game changer for me & the family at todays gas prices.
I just fitted one of them for my father who lives in a Park home . It works brilliant and heats the home so much faster than his central heating as its blown air . Blown air heating is very good and can help deal with condensation. I think having the heated air intake from outside will introduce moisture so better to circulate from inside. Just make sure you have a co detector in the area . Inside.
Hi Mark, great video! What is the box you have this in? I’m looking for one just like it to do the same thing. Could you also show a bit more of how the box is set up in another video. Thanks for sharing.
Good on you for making people aware of these little heaters I would add have a battery backup to power the unit if it’s one that uses glow plug they are planning for blackouts soon even a 12volt car battery is better than nothing when the power goes out you can stay warm at least
Actually, very often a 30 kW boiler refers to a combi boiler where the 30 kW output is on the hot water. The heating output is less, sometimes by a wide margin, such as underfloor heating. For example, 70,000 BTUs (yes, I'm an old engineer) is equivalent to only 20 kW. And that would give you ample 'heat' for heating a 4-bed house. Thanks to home efficiencies, most modern rooms only need between 1.5 and 2 kW - so 20 kW is over 10 rooms capacity. A 5 kW diesel heater really would go some way towards providing you comfort heat in an average home, especially as the heat is convected (forced draught). Two diesel heaters would probably see you getting away with shutting your gas boiler off completely. Can the poster tell me what make of heater that is, please?
Hi Jim - you're actually completely right and obviously know what you're talking about. I tried saying that in a mechanical engineer (hamfisted) way in a previous video and got slated for it. I haven't had the GCH on this year yet and although not winter yet, it's providing the whole house's heat. Thank you.
@@MarkIansonProperty Thanks, Mark. You've really got me thinking about this, as my house uses 14,000 kWh annually. I think I am going to have to do some research on these and buy one. The 8 kW ones I have just looked at require a 12v supply. That's normal, is it? Which one did you buy? Thanks for posting the video - we need people like you.
@@jimskirtt5717 Some say that there's only really two types, the 2kw and the 5kw - I've seen them branded as 8kw but, that might just be marketing. I've got a Hcalory as it came in it's own case, so it's simpler to site
@@jimskirtt5717 8kW?? Check out the pumping rate in the specification. It will need to deliver about a litre/hour for 8kW. The chinese (and the Uk suppliers) simply con a lot of people with their marketing hype.🙂
I've got a spare Eberspacher heater in my shed that I took off a 28 ft boat we used to have. I'd been considering using it in the house for extra cheap heat especially bearing in mind I have around fifty gallons of red diesel available too. I'm please to see others doing the same thing. I hope you're using domestic heating oil, not road diesel. It's much cheaper and basically the same thing.
I'd have personally connected the intake to circulate the inside air, for efficiency, then you can just choose to open a window when you feel like it, I like the video though, I had the choice between electric heating or diesel and I went with diesel!
This sort of innovation is what Britain was built on! Brilliant idea and, with a basic d.i.y skills, easily installed. No doubt the government will ban the use of diesel heaters but, in the meantime, this would prove invaluable to o.a.p's and struggling families if someone could, at a very reasonable rate, completely install these into people's homes..say a one off price of £400 for equipment and installation(just guessing the cost). If someone could, professionally and safely install a diesel heater(s), with a digital readout with start/stop function inside(just like they have in a campervan), change over lighting inside to low power led lighting all for a single cost(depending on how many heaters and lights needed) you could have a growing and successful business. It's funny though, with so much renewable energy available but such extortionate energy prices people will be turning back to burning fossil fuels to warm their homes, or even cook. How many homes still have old fireplaces that are boarded up? I wonder how many people are now using wood/multi fuel burners or will be using them this coming winter? Or how many boarded up fireplaces will be renovated and put back into use? So, renewable energies and the green agenda may actually cause more pollution from people trying to keep warm/cook food through burning fossil fuels.
But diesel is really expensive. Even though the cost of the heater itself is low, over time the cost of diesel will make this unsustainable. I have the 8KW that I use for camping in the winter. Running at 75% capacity non stop, the 1Gallon tank of diesel last about 20 to 24 hours.
Like everything mechanical, if you run at high power all the time it will use a lot of fuel. This is a top up to GCH not a stand alone so it's used as a boost and settles into low power mode when temp is reached.
Recirculating is the way to go, I get the point about stale air but it sounds like your older house is draughty enough for that to not be a problem anyway. What this is currently doing is creating a positive pressure inside your house, therefore forcing warm air out. Recirc would mostly eliminate that. Its a similar story as to why portable air con units aren't as good as the 2 part systems, because the portable ones create a negative pressure and pull warm air in from outside in the hot summer.
Doing a google search suggests that diesel heater use approx half a litre per hour. Thats currently about 87 pence per hour to run. I live full time in my campervan and im spending £30 per week on diesel in my heater. I dont know how that compares to gas or electric.
Hi Mark, great video. I have just purchased one for my workshop a few days ago and now UA-cam is bringing back lots of related videos. What a great idea, just having this trickling over to keep the temperature up a few degrees in the winter to reduce the demand of central heating. I like the box you have housed it in. Did you make the box or was that purchased? I think I will be buying another one for my house as well. Thanks very much 👏👏👏
@@bonesshed. I haven't fitted mine yet. I am finishing my shed/workshop at the moment. I am just at the point of first electrical fix, membrane and insulation and still trying to paint when it's not raining. I was going to use an oil filled radiator or one of those tube heaters used in greenhouses. I can't wait to fit my diesel heater. Report back when you have fitted your heater. Are you fitting it on the inside or outside. I will Defo go with the Amazon box and have the heater outside. I don't fancy running the exhaust through the shed walls. Maybe see a video from you on UA-cam with your diesel heater installation?
Great video, I am a domestic gas engineer and have installed a few of these diesel night heaters in my friends campervan conversions. The truth is a 5Kw unit would probably keep an average home in the U.K. to decent comfort temperature even in below freezing ambient temperatures
Hi great video easy to understand. Was wondering that as you say old victoriana houses .mine isn't but has same principle flooring under neath.could I run this through the air brick and heat under floorboards as floor always cold.
I have mine inside using inside air. The exhaust is redirected into my radiator water boiler to absorb even more of the energy before it gets exhausted in the chimney. The chimney bricks absorb the last heat available and i cant feel any heat at all on the top of the chimney=)
There is no way I would have an exhaust within several meters of a fresh air intake. Weather conditions make this an accident waiting to happen. Even on a still night these fumes will not disperse. Not even considering diesel particulates which are emitted. Health hazard.
If you observe the cloud of exhaust around a car on a frosty and still morning, you'll get some idea of the seperation required. This setup will surely be drawing in exhaust fumes in those conditions.
I use a Paraffin Inverter heater which, if used sensibly, gives very economical heat. These heaters have many safety checks, CO2 , movement etc. Found on Amazon, not cheap but worth every penny.
I use one of these in my shed. On half heat ( No3 ) it burns around 1ltr an hour , which is currently £1.40 a ltr so I would say it's about four or five times more expensive than heating my whole three bed semi., to 20 degrees, and it only just manages to heat my shed around 5 degrees over ambient. It is without doubt the most expensive way to heat space that I have ever tried. All I can think of is that for some reason or another, there is something radically wrong with my practically new diesel heater.
Have you considered capturing the considerable heat that comes out of the exhaust, by running it through coiled copper within a sand battery, perhaps in your porch or hall? It would act like a traditional storage heater and the exhaust fumes would be sealed in the copper tubing within the sand tank/box, and cold by the time they’re vented back out. It’s an awesome way of maximising the cost of running it. I have also seen videos where people use a traditional cast iron radiator as well to run the exhaust through….which is definitely more aesthetically pleasing than a steel drum/container. It would just mean having one inlet through your wall for the exhaust into the radiator/sand battery and then one back out. Great video by the way….and you’ve made the heater unit look very neat and unobtrusive. 🙂👍🏻💕
What a informative video. I have a conservatory that is impossible to heat in the winter. As soon as the central heating is switched off it gets cold within minutes. Something like this would would perfectly through the night.
Great one Mark, any solution to these modern times is worth looking at for sure , we’re do ya buy these heaters , presume they are for lorry cabins as night heaters , ? Thanks Shane uk 🇬🇧
hot water draw is about 28kw depending on draw.... the heating side of your boiler generally runs at around 13kw and doesnt stay on continuously, rare you find a boiler running heating at max as a constant.
There needs to be a down slope on the exhaust pipe to drain condensation. Or drill a small hole at the lowest point. Also, in this position rain water could accumulate.
Great video 👍 I would install one or two of these in a heartbeat if I still lived in a house, I'm currently in a flat which is part of a listed building so can't do anything like that!
Hi, you can put the heater inside and the exhaust and air intake for the burn from the outside. They ae efficient and you can use Red Diesel or Parafin to run them on. Take care M.
What are your thoughts on a home fit? The unit will be fitted outside Do i re-circulate the hot air in the room? 2 vent holes drilled or , drill 1 hole and leave the other intake outside in fresh air? what are the pros and cons, been as we dont have very Harsh winters now.
I left the intake outside as it works fine and gives fresh hot air...a side benefit is that this way gets rid of condensation on single glazed windows - who knew..?
Iv one of these in me caravan and the boat....i waz thinking about the house....but what you ain't showing the folks here....is were you put the ducts...does you haves the ducts alover the house or just in one room....be interesting to see a video about that pal much appreciated ty.
Only change to be made is the intake should get air from inside the house, this way is mpre effective as doesn't have to heat the cold air from outside
Have you got any updates on this system Mark. did you put the controller indoors. I'm doing the same but thinking about solor powering it. How much electric does it use per hour
Well done video. I have a victorian house with all the quirks you mention. Its our large hall with very tall windows that cools all our house. This would help? How does it come on and off please? Is it a manul thing or is it temperature related switch on etc? Thanks in advance for the reply.
Really like the look of this installation, job well done. Couldn't detect the typical click, click, click of the pump - being outside, I don't suppose that matters too much

By having the heater air inlet on the outside of the building you are causing positive pressure inside the home stoping cold air entering through the gaps
I installed one of these under the stairs inside the house with just the exhaust going outside (fuel tank outside!). It has already done 3 winters and has been a blessing with only a log burner in the house for heating. It gets the whole house (small 3 bed) up into the 20's and very comfortable in no time. We now only use the log burner in the evenings since having this even in sub zero winter months.
Ducted warm air systems were very fashionable back in the 70s over here in the U.K. for smaller houses but didn’t really catch on as some customers complained that the warm dry air caused them to have dry raspy throats. Eventually houses went back to wet rad systems on a gas boiler. They are now also on their way out (2026) for new builds to be replaced by electrostatic heating and ground source heat pump systems. (No gas in new builds after that)..
What a load of shite , you need to do some maths , one litre of oil can only produce 10 kw of heat total maximum at 100% efficiency , oil costs £1.60 pet litre , so if your 5 kw heater is 100% efficient it would cost £0.80 pence per hour to run !! Not £0.12 pence as you say the real problem is that your heater is only 80% efficient so the real running cost is £0.96 pence per hour , or to put it simply £24 per day approximately!!!!!!! Unless your heating a 4x4 room up . With a thermostat to switch it off for 23 hours , you are totally conning people who really cannot afford to put there heating on let alone afford to buy install or run a pice of shit that is designed to heat a lorry cab , just a thought if your that tight and you cannot afford your gas bill why not sell that posh house and down size you prick 🤔
if you dont have gas central heating then bang on..... no good for a house with central heating
What's that you say? It's efficient and gives you some degree of self sufficiency? Better ban it quick!

What a great video!!!! I’ve been heating my flat this way for the past two winters, It’s saved me 1000s apon 1000s overall and it’s actually very efficient and instant heat. A full tank lasts two days on lowest setting, my “electric” panel heater’s cost about £12 each on a cold day, I have three of them, normally looking at about 20-30 quid a day for electric. A full tank on the diesel costs about £10 for two days!! It pays for itself in just a month!
I like how this guy has built a permanent outdoor box, that’s impressive and sensible. Mine is indoors and may save some diesel with recirculating air, however I’d rather clean air coming inn especially inn the autumn. Don’t buy this if you have no idea on combustion or flues. This outdoor box invention really is a good idea! so glad I spotted this video…..thanks for sharing!

As an engineer that has installed two diesel heaters in my house, you have explained this soooo well. Better than anyone else on the internet. They give brilliant background heat.
Some installations on UA-cam are so clumsy, and look dangerous. Well done Sir.
Thank you, appreciated.
Great video. Just a little tip, I saw this on a US video, the exhaust baffle should be level and the little opening in the centre/bottom is to allow moisture out condense and drip out. Currently, you’re gathering water in the bottom left side of it. The rest of the exhaust should be level not facing up. Hope this helps!
Thank you
Great tips. I will also add to have the exhaust even further away. The reason is that your setup is in a corner, so the wind could create a mini tornado and the fumes going to the intake. This has been seen more than once at dive centers with a bad compressor installation and they filled scuba tanks with toxic fumes. And if the wind comes from the right, it'll push back the fumes to the intake as well since the turbulence will spin in the corner.
I don't know much about anything - but wouldn't you want to insulate the hot air outlet so that you don't instantly lose heat?
And if the "cumbustion" air is hot, wouldn't you want to coil it round the hot air outlet for the length of which it's still hot? (or around the air intake to pre-heat the air a bit)
Does the temperature of the fluid affect the performance? In that case you might want to insulate that as well.
What an absolute great idea, and kudos on sharing this video👍🏼
I understand what you mean but just for clarity. In old houses earth under a wooden floor doesn't transmit cold into the house. The heat from the house transfers to the cold area under the floor.
Heat energy always transfers from a hot area to a cooler area. I had a lot of trouble with this so I temoved the floorboards, insulated beneath them and replaced the floorboards. This took some time but it made a massive difference to my heating bills and to our living comfort.
Thermodynamics
You're right but, the house remains cold...that was the point. The heat at the floor is always colder in Victorian houses because heat rises. The top of the room heats up first and it takes a lot more energy for the heat to get to the bottom of the room.
Absolutely brilliant, thanks for the video Mark! Considering giving this a go myself
1l heating oil 72p contains approx 10. kwh of energy. 10kwh of gas =£1.50. 10kwh of electric £5.20 (Oct 2022 UK).
Very nice installation!
I am testing my diesel heater which had been sitting in a box for a year. I put it inside the house clamped to the top of my fireplace wood stove insert. I drilled and tapped a 3/4 inch pipe thread hole into the wood stove and the corrugated exhaust pipe fits the hole perfectly. The unit is powered by a 12 volt lithium battery pack that I built a few years ago. It will power the heater for 17 hours on a single charge if the power goes out again. I have a central natural gas furnace, but it will not work without the utility grid power. In my area, the temperature inversion layer sometimes holds smoke down low, and the Air Quality District forbids the burning of fireplaces in those conditions. With the grid down, the diesel heater will be employed.
Exhausting the diesel heater into the wood stove eventually warms the stove top but also provides enough updraft in the brick chimney to draw combustion gasses out. A stick of burning incense showed the smoke being drawn into the wood stove lower intake such that no diesel exhaust will enter the house. The diesel burner keeps the living room at a comfortable temperature of 88F, 20C, with the central furnace shut off. I burn about 3 liters a day of diesel on the H2 and H3 settings. The central furnace burns about $12 of natural gas a day to maintain 62F, 17C, but 3 liters of diesel costs me $4 US. In 4 days of testing, refueling was a concern until I found a plastic 5 liter fuel jug with a push button fill spout. I keep a towel handy but so far, the spout does not spill a single drop of diesel.
Great job
You can optimize it more, by elongating the fresh air pipe and adding another one, with a bigger diameter, over it and redirect the exiting combustion air in the chamber between the 2 pipes. The same should be done with the inlet combustion pipe. In this way you are using the combustion air temperature to preheat the inlet fresh air as well as the inlet for combustion air.
When I get mine I will like set it up with internal circulation (for simplicity). However after a welding course I'll make a box to mix the fresh/hot flows like you said - seems like a good compromise.
Also looking at extending the exhaust down the wall and through my electrical cabinet - it is big and contains my plumbing; this way as the pipe passes through it can keep that cabinet warm with the waste heat.
At about -6.6C my water inlet freezes up so this would be a useful secondary feature, albeit not used often.
Be careful with doing mods to these systems...it's not so called "common sense" it has technical implications.
@@jimosullivan1389 and Safety ones, no doubt?!
Good idea
Paul Pantione designed and patented the reburner you speak of..
That is GOOD, crikey I have a little fan heater that would cost ( at my current tariff) 54p an hour to run. Really made me think watching this.
Maybe worth pointing out that a 5kw heater like this might not be enough for an old draughty Victorian house as you say but if you have a reasonably modern, open plan house, well insulated and are happy with room temps a bit lower this could be used in isolation
this is awesome. i live in an area with an extreme air pollution. using "fresh air" from outside would be risky. in my loft, i installed a high performance air filter. DIY myself from scratch. 50m3 per hour dual hepa and activated carbon cylinder handled by 100mm RAM fan and ducting system. that lowered the in house smoke pollution from seriously dangerous levels to negligible. i think that both the diesel heater and the air filter could work in combination.
just got one of these a while back and its just sat there doing bugger all. youve gave me a kick up the arse to get it rigged up cheers.
They are sorted Mark well done. We have one in our garden shed bar. Top tip though Mark, make sure your ambient air inlet comes from inside the house. You will have trouble in winter where the ambient air will get too cold and prevent the burner from running at full temperature and fouling up and shutting down, which then often requires a strip down 😉👍
Good tip, thank you
Yup. I recirculate mine. Good vid. 👍
Unless your mechanical minded person you will find it difficult to keep it running I used the webasto water and air heater for 20 years although they been around for 30 years it would be one off the best however if you had to pay everytime it stop it would cost a fortune if you use diesel it will block up with soot and need strip down and cleaned at least once a year best to use kerosene it much cleaner and cheaper under 1 pound a litre uk service every 2or 3 years ps when we used then in camper van we got nothing only complaints to do with fan noise and the constant ticking off the fuel pump however this may not be the case here as the unit is out side the house however the down side to that is it outside when it needs refueling or service plus the damp which they don't like however it is Chinese and fraction off the price webasto which it was poorly copied off and maybe spare parts could be hard to get I'm just making some facts known before everyone rushes to eBay as the excitement could be short lived also these heater were never intended to run all-day every day (keep warm )
@@patkelly9907 Some valid points there...they're not for everyone but, serve a purpose for some.
yup, personally my first instinct would be to combust the air from inside the house too.
I'm currently planning to build a tiny house for next summer (2023), and I had this alternate heating source in mind. I even already bought a fuel tank, brand new, from a thrift store the other day!
Certainly doable as a secondary heart source after log fire ..
@@thorselckmo7378 That's my plan :)
I have installed 2, there's a way to replinsh the heat from the exhaust by using an egr from a diesel car and running a pump with water, or antifreeze straight into a radiator, that way you are utilising 100% efficiency from the heat produced
What is the egr doing in this idea
@@leeyo5494 EGR would imply that the exhaust gasses are recirculated into the combustion air to burn off any remaining hydrocarbons. However it almost sounds like they are recirculating the exhaust gasses through an air to water intercooler to dissipate the heat from the exhaust, and convert it into additional heated air.
I think that you are referring to an EGR cooler, that's a good idea 💡
I fitted one in my home workshop two years ago. At that time red diesel was 69p a litre. Last year it was 99p now it’s 1.35! It’s getting more and more expensive to run them but still far cheaper and more efficient than electric. Mine is a 5kw and over 8 hours it uses a shade over 1 litre of fuel. Currently costing 17p an hour to run. Two years ago it was 8.5 🥹 Recirculating the air won’t make it run more efficiently or use less fuel but it will mean the outputted air will be slightly warmer but it will be negligible.
Great idea. Good for a greenhouse too! Ps You can buy a pellet stove. Uses wood pellets And very efficient
Was thinking about this , great thats some one done it , great for sharing

Done this last year works great
The way you have it installed is probably the most inefficient way to do it, it will not be very effective in really cold weather. Recirculating would be just one step in the right direction. This heater has to be located inside the space you're heating in order to be efficient, only with exhaust and burner intake going outside. Ideally in some adjacent space like the basement or utility closet and air in/out vents going to the main space you're heating.
Very good, Mark. Im looking at doing something similar, hence this visit !
Fitted two to my ground floor a number of years ago, plus one in my work shop and one in my van. They can save money if you don't run them flat out.
Your absolutely right Mark, it won't heat the whole house, I've just done a similar install to you but I've placed my heater in my cellar and vented the exhaust outside, then run the hot air pipe through the floor, and under my kitchen floor units, to act like a plinth heater fan. To be honest I'm a bit disappointed, it's not as good as I'd hoped at heating my kitchen/ dining room, and it certainly won't heat the upstairs as well, I think some of the other videos on UA-cam with people saying they can heat the whole house are stretching the truth slightly. They certainly help but they are not a replacement for your central heating system.
I have two, one is a 2kw (for one room) and the one in this video is a 5kw. It won't heat the whole house, as you say but, maybe a 5kw will do more for you.
@@MarkIansonProperty it is a 5 kw that I've got it's an old Victorian end terrace house that I'm renovating, so at the moment it's not the best insulated. This will improve in time, so performance may improve, but at the end of the day they're not meant to heat houses. But every little bit helps, I have a log burner too, so it's not too bad. Plus gas boiler when I absolutely need to use it. I thought about putting a diesel heater in my loft, and venting hot air through the landing ceiling but I'm not too sure how safe that would be? It's the upstairs that gets coldest.
@@HappyTyke25 The one in the video is piped to go up the stairs...it doesn't heat all of the rooms but, does make the upstairs warm.
another top tip. Route the exhaust pipe through an old empty radiator. There's still plenty heat in the exhaust gas and you can use it. Bumps your effiency from 65% up to higher than 90%
That’s a good idea 😊
Bad idea. You want free-flowing exhaust on these so they burn efficiently, also if you are talking about running the exhaust inside through radiator and then back outside that is just asking for carbon monoxide poisoning.
@@moretrash4you correct.
@@moretrash4you Not necessarily correct. If you use a small fan downstream the radiator, that can completely made to balance out the flow restriction of the radiator. Also you can handle the CO poisoning by 1. Having a tight system - you are normally not having water seeping out of your radiators and piping do you? 2. Have a CO alarm to warn if the unlikely happens.
@@moretrash4you a big radiator will not pose a big obstruction to the exhaust flow and of course you'll still route the exhaust outside
Been driving lorrys since the 90,s so no stranger to night heaters but this is a great idea !
Absolutely brilliant video. This is the best in home install I’ve seen and I’m inspired! Few questions - could/would you put up a link for where you bought the green box from? Also you seem to have your heater in a suitcase inside the box. Is that something else you added, or did your heater come in this box? Finally, cavity insulation, did you have to do anything to remove the insulation from around the hot air inlet into the house! We are struggling like crazy with the rising cost of keeping warm. I have installed one of these in our camper and two in a couple of old VW beetles. Seems the next natural step for me to install it in my house !
My house is sold wall, so no cavity to go through. The Hcalory comes in a box already, the outer green box is from eBay branded as an Amazon parcel delivery box
@@MarkIansonProperty really helpful. Thanks for taking the time to reply, mark. I’ll let you know how the install goes.

Over a year for mine Mark. Mine sits inside house but fuel intake and exhaust sits outside. Cold this evening but 23 degrees in here. I do have central heating but rarely use it. My air intake taken from inside. I get your point about fresh air but heater will be very inefficient sucking in freezing cold air in winter. Mine HAS replaced my central heating but you do need to leave all interior doors open.
Where did you buy your heater from my friend?
Just curious how this is beating the cost of living? I understand that having these heaters in cooler areas of the house can provide a comfort convenience. But when factoring in savings on primary heat while running this supplemental heat, is it actually cheaper? Here in Canada I believe natural gas is quite cheaper than diesel. Can you share your cubic meter and per litre prices for gas and diesel?
Great video by the way, I like the idea of experimenting with different fuel sources and setups.
We are $0.0979 per cu M
$0.0923 per KWh
And currently $2.08 per L of diesel
Diesel is usually between $1.60-1.90 per litre.
Thank you
I believe whenever possible the cheapest and more environmentally friendly options is geothermal, as long as you have a backyard it is possible to do it on a moderate budget. After that I'd say solar, and on a third place natural gas.
@@zaratrusta79 my freind has geothermal its no cheaper
@@S99-c5s how is it no cheaper? the installation costs if it’s a DIY project are quite affordable, and maintenance is extremely low. Other than that the energy itself is free, it naturally uses the differential of energy accumulated in the underground.

@@S99-c5s take a look at this guy,
ua-cam.com/video/xc_BbbMi1cg/v-deo.html
everything is very well detailed in his videos, he’s definitely not lying. There are running costs because he’s using a heat pump, still it’s way lower than a conventional AC unit because it’s taking advantage of the free energy on the ground, and you can offset it with solar (like he does). I suppose with an even more efficient system (bigger loops, very well insulated house) you could entirely offset the heat pump running cost or with a fully “passive” system you could entirely go without heat pump thus reducing running costs to virtually zero.
Everyone's an expert, and everyone's got an opinion - but...from other sites, it would help if the unit was high enough for you to avoid putting the exhaust pointing up anywhere. Apparently, you can get a build up of moisture in the bottom bend. Excellent idea and video - I'm doing this once my heater arrives.
Your 24 or 30kw boiler is mostly devoted to hot water production if it is a combi. If you have a small maybe 6 -8 radiator house then the heating part of that might only be 10-15, call it roughly 1.5 per rad.

Nice video. 👍
NOTE!!! I have a Chinese diesel heater and whilst they are very good and economical there is one major flaw with them and that is they should come with a battery back up in case of power failure. The reason I say this is when you turn the heater off it take about 5 mins to wind down and within this time the fan continues to run. If the power is shut off at the mains or there is a power cut then the fan stops and the heat stays inside the unit and could be a fire hazard.
So it still needs electricity to run ? That's not practical.
battery backups can be bought separately
@@lise1255 maybe 10 watts to run the fan and 100 watts on initial start up for a minute or two. I doubt you'd even notice a change to your electricity bill.
As for the power cut issue just run it off a leisure battery and keep it topped up with a trickle charge.
@@antman5474 Better to use a smart charger which turns itself off when charged,
saving electricity.
I've got a model that goes up to 8kW. The fuel pump doses 0.02ml per cycle, so at the fastest speed (5.5Hz/cycles per second) it uses 0.02 x 5.5 x 60 x 60 = 396ml per hour.
Red diesel currently costs £1.30 in my area, so £1.30 divided by 1000ml = £0.0013 per ml, times our 396ml in an hour = £0.51.
Divide that by 8 to get a single kilowatt = £0.06 per kilowatt hour.
6p per kW/H is very attractive in comparison to 35p per kW/H for electricity or 10.3p per kW/H for gas.
Of course we have the additional electric cost of powering the heater, which is high on startup but drops during use.
None of that stacks up. Total energy in 1 litre diesel is 10kWh - and that's if you can burn it with 100% efficiency. So it it costs £1.30 a litre, and you reckon it only gets through 396ml an hour, the maximum the heater can be outputting is 3.9kW.
@@fredderf6491 The pump doses 0.02ml per cycle so it's just maths.
@@GaryMcKinnonUFO Maybe you shouldn't believe it really produces 8kW. Fred's data and math is correct, so something in your data must be wrong, that's probably the 8kW. And you can't burn with 100% efficiency, a lot goes out of the exhaust, so that 8kW you are using is probably closer to 2kW.
Mains gas currently 16p per kWh, plus Vat. Diesel nearly 10 kWh per liter or 20p per kWh with fuel at nearly £2 per liter. No standing charges with the diesel heater.
You would use agri red diesel at approx £1.25 pl
There is more to it than that. Localised heating. Reduced fuel flow rates possible. Oil can be stored. Not all are on a gas main. There is a price for the electric to run the heater.
@Spirit - you are correct: 1Kwh produced from diesel does indeed cost 20p. How can anyone therefore hope to run a 5Kw heater at full chat for 12p an hour?
A great informative video.
A lot of people are now sneaking these into their everyday life and using them for the home. I say fair bloody play to you all! I have 2 in my workshop, 1 in my utility area as thats not heated and a portable one for the summer when on the patio having a beer in the evening especially, when the missus is chilly, she loves it!

Hi.
Have you used a kerosene
@@CharlesPiston Yes, it burns hotter (which is great) but doesn't have the lubrication properties of Diesel. (some will argue) You can suffer early pump failure and this has happened to my neighbour that has a small canal boat but that said it took about 2 yrs to happen and that was running on pure kerosene. So I use a 50/50 mix and have done for 9 months now and I have had no problems so far. hope this helps.
@@crazy-diamond7683 Nice one mate. Thank you very much
Had plans to do this for a while, But not owning the property i thought i would have to put outside, But wasn't sure it would be good enough. Now i will un pack one and build a box.
I'm using a 8kW diesel heater to heat my small condo - I ended up using about 5 gallons US in 10 days, about $30.00 US, which means it will cost about $90.00 US a month to heat my condo. I only have electricity for heating (no natural gas lines in our old building), so this little diesel heater is far more economical to run. It will even run off one of those solar battery power systems and is portable enough to use for winter camping - no wood stove in the tent! The only thing different in my set-up is I have the fuel line running directly in to a 5 gallon fuel can.
Spot on - next step is to run on solar, when I've figured it out.
Your 8kW heater does not exist, if it is of the cheap chinese variety. It would need about a litre per hour for 8kW. Your 5 US gallons is 20 litres. Ten days is 240 hours. Go figure.
They are not even 5kW output, actually, so might last 40 hours at full tilt. I don’t disagree with your costs, just the real size of your heater. Let’s not exaggerate how good they are on fuel. S litre of diesel only contains about 10.5kWh of energy.
The 5 and 8kW heaters have the same output it's only the sticker that is different
@@benwouda yup, you got it
You could plum the could inlet into the house and a have a tapping on the inlet to allow fresh air in as well..sort of a T piece. It would be more efficient and still give fresh air in.
can you put a link to the diesel heater you use?
Do you have a link for purchase of the whole set up you have , including the box . Great video btw game changer for me & the family at todays gas prices.
Not really, I got different parts on eBay
I just fitted one of them for my father who lives in a Park home . It works brilliant and heats the home so much faster than his central heating as its blown air . Blown air heating is very good and can help deal with condensation. I think having the heated air intake from outside will introduce moisture so better to circulate from inside. Just make sure you have a co detector in the area . Inside.
How about the repairing costs
@@tamasszuroes9451 you can get replacement parts very cheap and the actual whole unit you can get for around £100
Been running night heaters for years in my camper , great bits of kit
Hi Mark, great video! What is the box you have this in? I’m looking for one just like it to do the same thing. Could you also show a bit more of how the box is set up in another video. Thanks for sharing.
Absolutely answers all my questions.
Excellent and thanks 😊 👍
Please could you send a link to the heater you are using?? Thank you.
Good on you for making people aware of these little heaters I would add have a battery backup to power the unit if it’s one that uses glow plug they are planning for blackouts soon even a 12volt car battery is better than nothing when the power goes out you can stay warm at least
Actually, very often a 30 kW boiler refers to a combi boiler where the 30 kW output is on the hot water. The heating output is less, sometimes by a wide margin, such as underfloor heating. For example, 70,000 BTUs (yes, I'm an old engineer) is equivalent to only 20 kW. And that would give you ample 'heat' for heating a 4-bed house. Thanks to home efficiencies, most modern rooms only need between 1.5 and 2 kW - so 20 kW is over 10 rooms capacity. A 5 kW diesel heater really would go some way towards providing you comfort heat in an average home, especially as the heat is convected (forced draught). Two diesel heaters would probably see you getting away with shutting your gas boiler off completely.
Can the poster tell me what make of heater that is, please?
Hi Jim - you're actually completely right and obviously know what you're talking about. I tried saying that in a mechanical engineer (hamfisted) way in a previous video and got slated for it.
I haven't had the GCH on this year yet and although not winter yet, it's providing the whole house's heat. Thank you.
@@MarkIansonProperty
Thanks, Mark. You've really got me thinking about this, as my house uses 14,000 kWh annually. I think I am going to have to do some research on these and buy one. The 8 kW ones I have just looked at require a 12v supply. That's normal, is it? Which one did you buy?
Thanks for posting the video - we need people like you.
@@jimskirtt5717 Some say that there's only really two types, the 2kw and the 5kw - I've seen them branded as 8kw but, that might just be marketing. I've got a Hcalory as it came in it's own case, so it's simpler to site
@@jimskirtt5717 8kW?? Check out the pumping rate in the specification. It will need to deliver about a litre/hour for 8kW. The chinese (and the Uk suppliers) simply con a lot of people with their marketing hype.🙂
@@oliver90owner
Thanks for that. It's on ebay under this heading:
12V Air Diesel Night Heater 8KW LCD Remote For Car Truck Motor Boat Home Bus UK
great video can i ask where you got the green box and whats the paint you used for the pipes and tanks
I've got a spare Eberspacher heater in my shed that I took off a 28 ft boat we used to have. I'd been considering using it in the house for extra cheap heat especially bearing in mind I have around fifty gallons of red diesel available too. I'm please to see others doing the same thing. I hope you're using domestic heating oil, not road diesel. It's much cheaper and basically the same thing.
Thanks, I'm using red diesel. Good luck with yours.
Paid £89 for heating oil 2 yrs ago it is now £500 unbelievable now ridiculously heating my home with electric convector heaters
@@statementallity red diesel
@@MarkIansonProperty where the hell can you buy red diesel ?
@@statementallity Some BP garages sell it from the pump - it's readily available.
Iv installed one in my conservatory whare I dry my laundry! Very good 👍
I'd have personally connected the intake to circulate the inside air, for efficiency, then you can just choose to open a window when you feel like it, I like the video though, I had the choice between electric heating or diesel and I went with diesel!
Where did you get the box
This sort of innovation is what Britain was built on! Brilliant idea and, with a basic d.i.y skills, easily installed. No doubt the government will ban the use of diesel heaters but, in the meantime, this would prove invaluable to o.a.p's and struggling families if someone could, at a very reasonable rate, completely install these into people's homes..say a one off price of £400 for equipment and installation(just guessing the cost). If someone could, professionally and safely install a diesel heater(s), with a digital readout with start/stop function inside(just like they have in a campervan), change over lighting inside to low power led lighting all for a single cost(depending on how many heaters and lights needed) you could have a growing and successful business. It's funny though, with so much renewable energy available but such extortionate energy prices people will be turning back to burning fossil fuels to warm their homes, or even cook. How many homes still have old fireplaces that are boarded up? I wonder how many people are now using wood/multi fuel burners or will be using them this coming winter? Or how many boarded up fireplaces will be renovated and put back into use? So, renewable energies and the green agenda may actually cause more pollution from people trying to keep warm/cook food through burning fossil fuels.
I have made a heat exchanger that goes over the exhaust which pushes more hot air via a computer fan.
You superstar...love it.
could lead to problems if any exhaust gas gets pulled in at the same time
But diesel is really expensive. Even though the cost of the heater itself is low, over time the cost of diesel will make this unsustainable. I have the 8KW that I use for camping in the winter. Running at 75% capacity non stop, the 1Gallon tank of diesel last about 20 to 24 hours.
use "free diesel", worn out car engine oil
ua-cam.com/video/zBHSSQ7iBjc/v-deo.html
Like everything mechanical, if you run at high power all the time it will use a lot of fuel. This is a top up to GCH not a stand alone so it's used as a boost and settles into low power mode when temp is reached.
REd diesel is still available to the agricultural and boating industries ...if u can find a supplier then its much cheaper and legal.
@@mickymost8887 Not in Polin :(
i got a 5kw diesel heater in my shed, it uses diesel at quite a rate, up to .5 litre per hour, i use low setting but still uses 2ltrs a day.
Recirculating is the way to go, I get the point about stale air but it sounds like your older house is draughty enough for that to not be a problem anyway.
What this is currently doing is creating a positive pressure inside your house, therefore forcing warm air out. Recirc would mostly eliminate that. Its a similar story as to why portable air con units aren't as good as the 2 part systems, because the portable ones create a negative pressure and pull warm air in from outside in the hot summer.
Furthermore I'm pretty sure depending on wind direction he's pumping contaminated air into the house, what a terrible design.
Doing a google search suggests that diesel heater use approx half a litre per hour. Thats currently about 87 pence per hour to run. I live full time in my campervan and im spending £30 per week on diesel in my heater. I dont know how that compares to gas or electric.
Hi Mark, great video. I have just purchased one for my workshop a few days ago and now UA-cam is bringing back lots of related videos.
What a great idea, just having this trickling over to keep the temperature up a few degrees in the winter to reduce the demand of central heating.
I like the box you have housed it in. Did you make the box or was that purchased?
I think I will be buying another one for my house as well.
Thanks very much 👏👏👏
Thank you, this is a box off eBay, branded as an Amazon parcel delivery box...pretty watertight with a sloping, overhang lid.
How have you found it ? Ive just yesterday bought one form y own workshop. I was running an oil filled rad but this should work out cheaper ??
@@bonesshed. I haven't fitted mine yet. I am finishing my shed/workshop at the moment. I am just at the point of first electrical fix, membrane and insulation and still trying to paint when it's not raining.
I was going to use an oil filled radiator or one of those tube heaters used in greenhouses.
I can't wait to fit my diesel heater.
Report back when you have fitted your heater. Are you fitting it on the inside or outside. I will Defo go with the Amazon box and have the heater outside. I don't fancy running the exhaust through the shed walls.
Maybe see a video from you on UA-cam with your diesel heater installation?
Great project, where did you get your lovely green box from?
Great video, I am a domestic gas engineer and have installed a few of these diesel night heaters in my friends campervan conversions.
The truth is a 5Kw unit would probably keep an average home in the U.K. to decent comfort temperature even in below freezing ambient temperatures
Thank you, we have the GCH on but quite low and the house is warm
Thats interesting. I live in a small cottage. I just want it to be able to take the chill off.
Hi great video easy to understand. Was wondering that as you say old victoriana houses .mine isn't but has same principle flooring under neath.could I run this through the air brick and heat under floorboards as floor always cold.
yup, you could
I have mine inside using inside air. The exhaust is redirected into my radiator water boiler to absorb even more of the energy before it gets exhausted in the chimney. The chimney bricks absorb the last heat available and i cant feel any heat at all on the top of the chimney=)
4:15 im in a house that was built in 2008 and this is what i have tounge and grove boards no insulation and just earth underneath really cold
Thanks for your comment, not sure if there's a question?
Nice install!
Also that exhaust is still close to the intake, so you'll still be breathing in exhaust fumes.
There is no way I would have an exhaust within several meters of a fresh air intake. Weather conditions make this an accident waiting to happen. Even on a still night these fumes will not disperse. Not even considering diesel particulates which are emitted. Health hazard.
If you observe the cloud of exhaust around a car on a frosty and still morning, you'll get some idea of the seperation required. This setup will surely be drawing in exhaust fumes in those conditions.
I use a Paraffin Inverter heater which, if used sensibly, gives very economical heat. These heaters have many safety checks, CO2 , movement etc. Found on Amazon, not cheap but worth every penny.
I use one of these in my shed. On half heat ( No3 ) it burns around 1ltr an hour , which is currently £1.40 a ltr so I would say it's about four or five times more expensive than heating my whole three bed semi., to 20 degrees, and it only just manages to heat my shed around 5 degrees over ambient. It is without doubt the most expensive way to heat space that I have ever tried. All I can think of is that for some reason or another, there is something radically wrong with my practically new diesel heater.
Have you considered capturing the considerable heat that comes out of the exhaust, by running it through coiled copper within a sand battery, perhaps in your porch or hall? It would act like a traditional storage heater and the exhaust fumes would be sealed in the copper tubing within the sand tank/box, and cold by the time they’re vented back out. It’s an awesome way of maximising the cost of running it.
I have also seen videos where people use a traditional cast iron radiator as well to run the exhaust through….which is definitely more aesthetically pleasing than a steel drum/container. It would just mean having one inlet through your wall for the exhaust into the radiator/sand battery and then one back out.
Great video by the way….and you’ve made the heater unit look very neat and unobtrusive. 🙂👍🏻💕
What a informative video. I have a conservatory that is impossible to heat in the winter. As soon as the central heating is switched off it gets cold within minutes. Something like this would would perfectly through the night.
Great one Mark, any solution to these modern times is worth looking at for sure , we’re do ya buy these heaters , presume they are for lorry cabins as night heaters , ? Thanks Shane uk 🇬🇧
hot water draw is about 28kw depending on draw.... the heating side of your boiler generally runs at around 13kw and doesnt stay on continuously, rare you find a boiler running heating at max as a constant.
How did you build it Mark? Thanks for sharing mate.
There needs to be a down slope on the exhaust pipe to drain condensation. Or drill a small hole at the lowest point.
Also, in this position rain water could accumulate.
Thanks, you're right
@@MarkIansonProperty Absolutely awesome how you're using this for residential heat :)
You can automate co2 your inlet /stale air
Hi, looks good, wonder if cooking oil is possible, used in older diesel cars enough
They will run on cooking oil
Great video 👍
I would install one or two of these in a heartbeat if I still lived in a house, I'm currently in a flat which is part of a listed building so can't do anything like that!
Hi, you can put the heater inside and the exhaust and air intake for the burn from the outside.
They ae efficient and you can use Red Diesel or Parafin to run them on.
Take care M.
What are your thoughts on a home fit? The unit will be fitted outside
Do i re-circulate the hot air in the room? 2 vent holes drilled or ,
drill 1 hole and leave the other intake outside in fresh air?
what are the pros and cons, been as we dont have very Harsh winters now.
I left the intake outside as it works fine and gives fresh hot air...a side benefit is that this way gets rid of condensation on single glazed windows - who knew..?
Iv one of these in me caravan and the boat....i waz thinking about the house....but what you ain't showing the folks here....is were you put the ducts...does you haves the ducts alover the house or just in one room....be interesting to see a video about that pal much appreciated ty.
Hi,
Great video, thanks.
Please could you put a link for your heaters in the description.
Monoxide is the stuff you get out of a 'M'OTOR cars exhaust, Dioxide is the stuff in fizzy 'D'RINKS pop.
Only change to be made is the intake should get air from inside the house, this way is mpre effective as doesn't have to heat the cold air from outside
Have you got any updates on this system Mark. did you put the controller indoors. I'm doing the same but thinking about solor powering it. How much electric does it use per hour
Thank you for this video! Where did you get the box?
Well done video. I have a victorian house with all the quirks you mention. Its our large hall with very tall windows that cools all our house. This would help? How does it come on and off please? Is it a manul thing or is it temperature related switch on etc? Thanks in advance for the reply.
It has a thermostat to control the heater
Really like the look of this installation, job well done. Couldn't detect the typical click, click, click of the pump - being outside, I don't suppose that matters too much
Regards from Poland!
