Be interesting with a bit of furnace glass over the end to see how it burns on different fuels. Great video cheers from a grumpy bastard from Australia
Ahhhh great minds think alike , putting my heaters away for the dry , at last it is staying around 20c at night mid 30s during the day . Need heaters at anything below 20c just to dam cold . Possible that I have lived in the tropics for to long
Heh, I came here to say the same thing! Would be quite interesting to see the difference between Diesel and Vegoil while it is starting. Then you could try heating the VegOil to somewhere around 60-70°C where its viscosity is not too far off of Diesel. Would be quite interesting to know what the failure point is. Burning temperature, viscosity/pressure, etc.
Reminds me to myself when I was a young boy. I had to disasseble everything even though some things rendered unusuable afterwards. But that's the way you learn and understand :-) Nice video - Greetings from Germany!
That is why my parents stopped buying me toys that were already in one piece. I kept taking everything asunder and making something different from the bits. It was Meccano, Lego Tecnic and Airfix kits from then on. These days its an engineering shop at home with several machines and lots of raw materials to play with.
Me EXACTLY.. air rifles, pistols, motorbike engines, you name it when i was an adolescent but it ,s put me in good stead as i can service and fix my own engines now saving thousands over the years on garage bills.
Very interesting to see and work out the flame path and the combustion setup of these burners. Looks like the disk in the middle is used to evaporate the diesel once the glow plug goes out. Might be some methods of operation I can build in to bigger waste oil burners. Trying to get one down to even 10 Kw is a challenge. Great Video David. Didn't waste anything, you imparted some good knowledge into a lot of people. Thank you.
David, I'm an avid diesel heater lover. But one year in I have found a serious flaw with some All In One Units. It seems that some of the All In One Units used sub standard fuel tanks inside and several have spontaneously developed cracks, thus leaking a full gallon of diesel fuel on the burner unit and into my garage floor. I thought it was a bad hose connection but found that some of the very thin fuel tanks were developing cracks. As you can imagine, a full gallon of diesel fuel leaking anywhere, but especially onto a running hot burner could be a serious issue. This is one of the problems with low cost Chinese goods. You can sometimes unknowingly get some dangerous products. Thanks
Imho one MUST keep the fuel tank a a distance from the heater and also from any electronics. Also put it a bit lower if possible so that when the hose burns or leaks the fuel won't leak out into the fire.
Since the water heating variant of these is so expensive, I have thought of tearing into one of these far less expensive units and exploring converting it to heat water. Thanks for the look inside.
Brilliant mate, really interesting and informative. As a HGV driver of 30 years I've never given it much thought how these auxiliary diesel heaters actually work, until now that is. Thank you for taking the time to make your videos. Kind Regards, Damian.
I've been wondering about the heat exchanger construction. I have been running 2 8Kw units in my bus for over A year now with no issues. Thank you for sharing this! Tim NH Usa
I've watched a number of your videos, David, and am much, much better educated as a result! Before then, these were just magic boxes working through who knows what supernatural means. Now, you have shown us that they are - at heart - really quite simple machines. I've just stripped and cleaned mine, replaced all the bits that need replacing and fired it up - off it goes. Couldn't have done it without you! One issue that keeps coming back to haunt me is exhaust length and build up of condensates and gunk. Mine's in a boat and needs a 6 metre run. So far, I can do no better than run it until it no longer goes and then clean/blast everything through with gunk so it works again. At least I now have the confidence to do it!
Great video explaining the inner workings of the diesel heater. Kinda thought it might work like an oil furnace used to heat a home. Just on a smaller scale. Same concept, though.
Whatever you decide to do with it remember that the more you reduce the exhaust gas temp the closer you will run to the dew point which produces acidic condense which is ok as long as you use material that is acid tolerant and you can drain the liquid.
Wouldn't adding a catalytic converter reduce the amount of NOx and VOC's present in the exhaust? Then, when you did produce acidic condensate in the exhaust you could filter it through another medium to capture any release carbon. Say, using the same idea as what they're already doing on large ships when using sea water to filtrate bunker fuel and illegally distributing it into sea water. A peristaltic pump setup on the exhaust end to pump the exhaust through a dirty water tank would cause any particulate to become trapped in the water. Like a dirty exhaust bubbler. Which, you could then send that dirty water to a distillation chamber setup on the exhaust itself since it'll be burning above 100 degree's. The water would steam off leaving concentrated toxic distillate or creosote. Which you could presumably use for something else. Like wood preservative.
@@1607rosie Ultra-high efficiency gas furnaces and instantaneous ('tankless') water heaters deal with condensate, which must be piped or pumped to a drain. Not a big deal; the units are built with corrosion-resistant stainless alloys. I have a Rinnai tankless heater which is built in this fashion.
You sound exactly like Scotty in the Star Trek movies! I've really enjoyed all your videos on these heaters. I've been using a Little Buddy heater in the back of my truck for truck camping - but after watching all your videos and test results, I'm gonna switch to one of these Diesel heaters since I can just use fuel from my tank instead of lugging around a huge propane bottle all the time. Thank you so much for taking the time to do all these interesting videos!
Quite an interesting video. :) Btw..you could punch some threads in there, throw a thin copper gasket on and assemble the whole unit again. It will be easy to disassemble when you want to clean it.
Thanx. I've wanted to know this too. Nice blue flame, low co. Tap between the fins and screw in threaded inserts. Heat resistant gasket or "Ultra Copper" tm. This can be returned to service. Better than new and easier to clean. :)
I was suprised to see bunsen burner blue colour initially when you took the thing out the way, that's pretty ideal burning. Somehow I expected a cooler yellower flame. They burn pretty cleanly and completely when its like that.
A very interesting video indeed, unique too, no one else has done this, and fearless of you to do, I would have the same curiousity but not the guts to attempt doing it. Best wishes from Alan, in England.
Thank you for the creative DeStRuCtIoN. It's design is much more clever than I would have guessed. I think it now deserves to be mounted on the back of a bicycle for the conversation value. Cheers.
@@2cooco IR thermometer readings probably not accurate as that needs a specific surface emissivity; a thermocouple reading would be more representative of the flame temperature.
Great video and no, it wasn't a waste, we all learned something from it. These heaters have incredibly clean burning and low sut accumulation. I was seriously thinking to make a water heat exchanger for one of these. It could help to rise the water temperature of a heat pump when it is very cold. I have 2000l water buffer tank and I heat it when there is sun or when the electricity is cheaper. It takes the water from the bottom, runs it thru coaxial heat exchanger where it leaves at 55°C max. I could add some 10°C perhaps and end up at 65°C. Worth a thought.
Or run the pipe between the cooling fins. Or wrap the whole thing in a jacket and pump the water into the jacket So many awesome possibilities for water/air heating
Excellent video mate, I have just bought one of those heaters for our motorhome and I like to know how they work, thank you for the information. PS, you sound very much like Billy Connelly 🏴👍
Respect to you!!! To be honest you could put some gasket sealant and tap the fins and bolt it back together just like a head. Great to see how they work, wonder if you could oil burn or kerosene feed.
I just got one of these and the one feature I wish it had was during the rundown process. When you shut it off I wish there was a mode that could keep that high-efficiency lowest heat, optional and quiet exhaust. I hope they create some sort of firmware update, or new controller that includes that run down in to off mode as a standard speed option

Amazing how the flame is blue despite running on diesel - usually as it's compression ignition in an engine it's yellow and produces a lot of soot but these clearly achieve near stoichiometric combustion.
Thanks for doing this - it would be interesting to see the intercooler setup, but must deal with the condensation somehow. Could just point the whole set-up down and let the condensate flow out the end, but rust may be the devil here.
Try adding a pyrex window. You could use a pyrex petri dish stuck on with high temp silicone. It would be interesting to see it under near real operating conditions.
Excellent video. Not sure where your at Scotland perhaps, but here in the States there was a TV show called "Deconstructed" and they disassembled various items I e. Tv sets, small engines etc... To show the inner workings and how things were built, it was a very good show, your video is very much like it. Thanks for sharing!!! ✌️
The glow when shutting down, plug where turned on to burn off any excess fuel. So if you’re operating the heater on it’s side, you should lay it down with the glow plug on the bottom.
Very cool video! I'm thinking of getting one of these to take the chill out of my basement workshop. Funny you should have mentioned an intercooler. I'm thinking of running my exhaust out through a length of hot water baseboard element. It's thin copper wall pipe with fins to let out the heat. Why let all that great exhaust btu heat just get wasted. Maybe you could try this and see if it works? I was thinking about a 1" dia x 4' length.
The important thing to remember is to fit the silencer Outdoors, as the seam welds are usually crap, and the condensation weep will both conspire to poison you with products of combustion if fitted indoors.
I really appreciate your effort, going so far as to cut the end of the burn chamber off. Opens up a whole new realm of uses and modifications. Do you feel that running the heater with the intake and exhaust to the side negatively affects the operation or lifespan of the heater?
I wouldn't have thought so. The diesel feed is just hitting the hot gauze and being vapourized before mixing with the air stream. Being on it's side shouldn't have any effect on it.
My old oil furnace burner ran much the same way. It also sounded about the same. Both inject heating oil or diesel. (Pretty much the same thing). The oil furnace sprays oil past a 10kv electric ark, while the diesel heater uses a glow plug. Seems like the diesel heater turns the glow plug off when the flame becomes self sustainable.
Really interesting to see diesel burning with a blue flame, the design of the airflow must provide plenty of oxygen and the fuel must be atomised into small droplets.
Nice blue flame = effizient and clean combustion. Yellow flame indicates soot building flame in combustion chamber. The overall design seems okay to me ( from what i see of it.)
8:45 Attach front piece with NASA approved high-temp zip-ties. Problem with extracting maximum heat from exhaust might be increased soot deposits and corrosive liquids in exit tube. Be sure to keep it sloping downward to outside of building. Also include a cleanout port at start of "Maxstractor Tube" to allow snaking it out with a long wire brush.
love this what you done you have made a small space heather in which i be using but did you do a video or not on taking the fan Assembly apart i cant find it
Great job! I wondered what the insides of the little monster looked like. Not only did he show us the bardun chamber, he had some large pustins from other onjuns lying around. I had a Scot friend from Preston Pans who I worked with for 2 years. Nobody could understand him. He called me Squirrel Meat. I didn't know why. Another new worker asked him why he called me that. It was then that I found out with his twusted Scot accent that he was actually calling me Scrotum Head. He would tell a joke in the lunch room. Nobody laughed. I would retell it in American English and everyone laughed. His answer to that...fookya, Barney!
These are cool. Came across these heaters a while and would definitely be cool for a camper. Better than any stupid electric ones. Buddy said they have water heater versions ? That's cool. Theres a few things you could try to make them a lil more efficient like using the exhaust gas to heat water , running the exhaust through another heat exchanger such as the body of another one of these heaters. Very cool.
This is something I’ve thought about too, my thought was to have a water tank with the exhaust pipe running through it in an S shape so the heat from the exhaust heats the water as it passes through.
I often wondered how they work, I'm now putting one in my Landover as my heater is useless like all Landovers .use that demo unit for spares, many thanks 🏵️

I think the idea of extending the heat exchange chamber is certainly a good idea. More heat expelled means more efficiency less fuel and less expense.

Hi David, thanks for sharing your work. Can you cook with the combustion chamber open? It would be a good device for truckers
Thank you. This helps me. Vegtable oil will not burn. I suspect if Vegtable oil is pre heated it would burn ok.
A viewer commented that he got veg oil to work as long at it was 100ºC as it entered the burn chamber.
Fantastic video very interesting and informative
Nice video. They have a temperature sensor at the exhaust so if you place it in the hot gas at some point it won't flamme out. Cheers
No sensor at the exhaust. There is one on the housing to sense undertemp and overheat. As long as the casing gets warm initially it will stay running.
I suppose, in theory, you could build a DIY one of those out of a blow-lamp and a cylinder block and head from a discarded motorbike engine.
A blow lamp head and a pipe would probably do. I made one like that a long time ago.

You could make a hinge and gasket with that front plate and use it to burn waste oil and clean it out super easy.
04:55 Very impressed. Nice blue flame, complete combustion.
Really cool Dave, thanks for the insight.
Build a chamber out of stove glass. Should look pretty cool
Cool video. Enjoyed watching this.
Thanks for the share, makes me wonder if a piston for a sterling engine could work in there nice and what rpm it would produce for an alternator.
love this what you done you have made a small space heather in which i be using but did you do a video or not on taking the fan Assembly apart i cant find it
Great job! I wondered what the insides of the little monster looked like.
Not only did he show us the bardun chamber, he had some large pustins from other onjuns lying around. I had a Scot friend from Preston Pans who I worked with for 2 years. Nobody could understand him. He called me Squirrel Meat. I didn't know why. Another new worker asked him why he called me that. It was then that I found out with his twusted Scot accent that he was actually calling me Scrotum Head. He would tell a joke in the lunch room. Nobody laughed. I would retell it in American English and everyone laughed. His answer to that...fookya, Barney!
These are cool. Came across these heaters a while and would definitely be cool for a camper. Better than any stupid electric ones. Buddy said they have water heater versions ? That's cool. Theres a few things you could try to make them a lil more efficient like using the exhaust gas to heat water , running the exhaust through another heat exchanger such as the body of another one of these heaters. Very cool.
This is something I’ve thought about too, my thought was to have a water tank with the exhaust pipe running through it in an S shape so the heat from the exhaust heats the water as it passes through.
Thanks for this experiment !!!
👍👍👍
Brilliant, thank you for posting.
I often wondered how they work, I'm now putting one in my Landover as my heater is useless like all Landovers .use that demo unit for spares, many thanks 🏵️
Thanks, was always wondering how that worked
A man after my own heart, let's cut the end off! Yea. Good video. Cheers 😁
