15p a unit… Luxury. The stuff of dreams Joe!
Against my advice my next door neighbour had his obsolete gas boiler replaced with Fisher electric heaters in each room.. This was during the spring.3 months later he wanted to sell the house. Every potential buyer was put off because of the electric heating. When he eventually sold it the new neighbours had the shock of there lives when they got the electric bill. Within mouths they had them ripped out and a new gas system fitted. These heaters had a very short life maybe 9 months max before ending up in a skip.
Another thing
. Anyone who’s old enough to remember video recorders will remember 90% of the population couldn’t even program them to record a simple .single program . Wind on 20 years 90% of the population haven’t a clue how to program these heaters and if they can they can’t be bothered. All they do is just switch them on and off.
In my workshop I have a old dimplex panel heater , it’s not used much but it’s got a mechanical time switch and a normal thermostat. How simple is that to set and use. Almost anyone can understand how to set it within seconds
Agree 100% with what you say about Fischer Future Heat (or any similar electric radiator heating system). To heat a whole house in this way is utter madness, tens of kilowatts per hour for 5 or 6 rooms.
These companies must employ ace salesmen to convince someone like your neighbour to rip out gas and go electric. I mean, after all, how much is a new gas boiler? £3000 ish fitted.
And I'm sure the new electric system cost many times that to install plus very, very high running costs.
An electric heater/radiator in one room is expensive (thermostat or no) but for all the rooms in a house ........out of the question.
Yep, i totally agree. Keep it simple.
how about now?
@@jamescat2386 im very curious aswell
Times change also I'm pretty sure you can't talk for 90% of the population never mind have the evidence to back it up, literally typed a essay of pure nonsense, I work with solar and I'm pretty sure electric heaters are really only for homes with solar I thought this was like common sense they go along side each other like two peas in a pod! And I could record on vhs when I was 4 if you struggle there is always a manual to refer too
With better temperature control you can set the temperature lower and still feel comfortable, most of the time thereby saving money. It cuts out that cycle of feeling cold, the comfortable then hot, then comfortable and then cold again (although as the structure warms up the cold feeling gets less of course as it operates like a block storage heater). To get over the cold periods one would be tempted set the temperature up, so the cycle becomes comfortable, sweltering, comfortable, but very expensive. There are more heat losses too at higher temperatures. The problem with fan heaters is that the movement of air can give an apparent cooling effect, not to mention stirring up dust etc unless fitted with a filter. Well controlled and well distributed heating is the best.
The issue that really gets mentioned is maximum demand. A larger house with 4/5 bedrooms, could easily have 10 heaters (20-25kW) . Add all the other demands like 9kW cooker, 3kW water heater, appliances, lights and the electric car charger point. Installation Demand after Diversity could easily exceed 100A. Would like to see a video how efixx would calculate max demand and calculate diversity.
Missed point is it’s not working constantly 8 hours! I think in average it will run maximum half hour constant in each hour. That’s mean is you will consume 3kw average for 8 hours. Not bad at all guys! Make your math accordingly. If you put lower temperature in the the night it may even save you a bit more.
For your opinion, it may not be much suitable for large houses (though as long as you don’t want save energy and just heat all house constantly). And another advantage is if you have large battery or large solar panel system this will run free! There is no chance you can produce gas at home but if you have a large house this may save you a lot of money. Just my opinion.
@@onderdogan6633 now there are solar panels that produce hydrogen. Innovations are the answer.....
can you guys do a video on the new scolmore click smart plus gear that came out this year to replace the older click smart range such as what encousures the switches modules can go in if they fit well in a backbox ect...
Hi Joe, to my mind since the conversion of electriciy to heat is 100% efficient, the amount of energy used is deteremined by the temperature set point, the size of the space you are heating and the degree of heat loss from that space (level of insulation etc). I agree that using a more sophisticated proportional (or even PID) type controller will give you more precise temperature control, it will not fudamentally change the amount of electricty used.
And considering you get a couple of magnitudes more using a heat pump instead of electric heaters for the same electricity... pfff
Well done mate as you given a valuable knowledge of electric heaters.
I have attended a block of flats where the oil filled radiators (Ducassa Advent range) have been fitted ( Which are absolutely useless as the side plastic control panel falls off after it melts from the radiator poor design) which just have a on off push button and temperature control no timer and are all controlled by a central heating programmer through contractors, The previous system was storage heaters but they were removed and contractors mounted in the off peak consumer unit .
with replacing the heaters again for oil filled radiators some of which are faulty which are now all lot 20 and with timer programs built in (Creda Aluminium radiator +Rointe) when the central heating type programmer switches off how long does the memory last or do the heaters have to be switched on manually everytime as they have touch screen displays where as the old type were mechanical push button?
Just curious
This heater's centrally controlled via an app so it has a permanent supply, all the switching is done in the individual heaters.
Oil radiators are controlled by thermostat and only use most electricity when switched on from cold after that the controlled by the thermostat set to the desired temperature, so how can they be the most inefficient electric heater ? Mine switches off when at suitable level then only comes back on if the room temperature drops, with fan heater the power is constantly on being most costly to run 🤷♂️
so it's like OpenTherm for oil radiators?
Very informative, thank you.
Thanks
I know of entire blocks of housing demolished because local councils decided to take out gas heating/enclosed coal fires and replace them with electric heating. The cost to run the heating was so high the people in them moved out and nobody would take them because they had electric heating. They ended up riddled with damp to the extent that it was cheaper to demolish them than refit.
Serves those greedy bastards right! No one should have to pay a fluctuating bill! It’s bullshit there should be a flat rate for unlimited electricity period!
@@andywooten622 currently costing the people in the remaining houses in the same place around £150 a week and it barely gets their homes up to 15c. The houses are well insulated and have double glazing...
The most cost efficient heater I think they call it a woolly hat and jumper
Or body heat, time to get partner exercise and lose some weight. It's a win-win.
Absolutely, heat is basically about comfort. Rooms don’t really mind being cold (within reason) , but people do. “Heating yourself” and/or your immediate environment is the goal, not heating big empty spaces while they are unoccupied. Often I think, brrr it’s getting a bit cold, I’ll put the central heating on, then I catch myself and say… “hang on, it’s January, and I’m in a T-shirt” 😀
And a stationary bike😁
@@brucekennedy5274 I see heating a bit like driving. You are paying for fuel to lug 1.5 tonnes of metal into town when you only weight maybe 70KG. Think about how many cubic metres are being heated just so you can keep the air next to you warm. I heat 1 room only. The room I spend most of my time.
You need to calculate food cost of the heat source. At least a banana every 15min.
Resistive heating generally is a bad idea. "100% efficiency" is misleading cause it only accounts for electricity conversion into heat. Many powerplants use fuel of some sort generating electricity and heat with ~30% and 60% efficiency respectively. Also, there are transmission losses of about ~5%
Other options would be: Passive solar heating, solar thermal heating, waste heat from various sources, heat pumps, CHP, or a combination of them :)
I had a similar discussion with electric shower was being told that a 7kw shower on low uses less energy. I say to them not true they say the water comes out colder so must use less. But it is the speed of the water threw the small tank. No I was not speaking to the shower was speaking about one. Not with one.
Clear 👍
15p a unit. Good old days. Now more close to 50p! And the house I'm in was fitted with new "energy efficient" electric heaters all round. Don't think they will ever be turned on unless prices return to normal. I'm even looking into gutting it all out selling it on and installing a big oil boiler. Great efficiency and atlest only marginally more expensive than gas depending on how cheap you can get 1000ltrs and your energy/efficiency rating of the oil boiler but most run at 10-10.5kq per littre of oil and someone worked it out to being even cheaper than gas at its current price!
The only way electrical resistive heating can be cost effective and or green is by adding a time shifting component and charging up with cheap(er) energy when it’s available. The increasing supply of renewables is not going to make peak energy cheaper, indeed we will see the opposite, with increasing costs during those winter evening peaks when there’s a chronic lack of supply. Let’s see storage heaters given a new image and linked to innovative tariffs like octopus agile.
It's probably going to need a combination of technologies to make it all work effectively.
Let's get back to basics; the amount of heat you need to maintain a certain temperature is the heat needed to replaces losses through walls, floor, ceilings etc.
So all electric heaters will use the same amount of heat, the only difference is how they do it, convection, conduction, or radiation.
A gas boiler system has other losses such as through the flue, so is less efficient. However with electricity being about 4x the price of gas there is a lot of price reduction needed for electric to be economic! There are a lot of comparisons with well insulated rooms and electric, but any heating will be cheaper the better the insulation.
Completely agree - they are talking about efficiency here so a panel or oil rad will chuck out pretty much 100% heat from electricity - how that feels to an individual's level of comfort is subjective depending on the transfer method and hence may be run for more or less time (not a factor if we compare like for like in terms of power and time) so this video seems more like a sales pitch ;)
Cost to run, which is a significant factor for most folks is the big killer versus gas and the only thing that comes close is a heat pump which will be more efficient than just literally "burning" electricity and come close to gas in terms of cost. On the downside heat pumps have a larger initial outlay sadly. Cost isn't discussed in this video which is deceptive in my opinion as those not in the know might be led to believe that somehow this new rad is a 'clean' alternative to gas but there are two aspects to the discussion - efficiency AND cost versus the alternatives!
Agreed, gas is cheaper when used as a heat source and I state this in the video, unfortunately it won't last forever. The purpose of the video was to give an idea of running costs for a heater. The future is definitely electric, most probably a combination of direct heating and heat pumps.
The short answer is; No they use their rated input in electricity.
The trouble with panel heaters and oil filled is the price of the electricity as currently it's 4x more expensive than natural gas and 3 x more expense than Economy 7 tariffs per kw. I currently have a landlord failing SAPs because of these heaters as they're chugging £3 a day per room x 9 rooms (student let hence the SAPs rating). The uni advise installing E7 heaters but they were removed due complaints from previous students due to cold snaps and on/off controls with a thermostat being easier to use. So although technically efficient electric heating can be quite cost prohibitive at times. Depending on whether you want to heat a space or feel warm, radiant heating may well be a more cost effective route.
Down here in good old NZ we've been heating our homes electrically and heating our water the same way for years. The average power bill at the end of last winter for me was about $230.00, per month. Now I am not sure how that works out to Pounds, shillings and pence. However that was fairly reasonable considering how cold and damp it was. An average household/ family might pay $400.00 per month. We just learn to deal with it. We too are becoming energy wise and using solar and wind, but more from an ecological stand point.
400 per month? I'm in a family of 7 and it's 50 a month wtf
If our bills were that much we would revolt..thats a incredible amount of money....
What are the rates by different energy types?
How much does gas cost per kwh?
Electricity?
How many kwh do you use annually?
Anyone any experience if Infrared panels??
I heard they are efficient and work well with PV setup??
Not much but maybe we can look at it,
So when the sun is shining fullbore your heater comes on??
@@Froggability well with battery or in Ireland we can soon, think this year starting, sell back to grid so in directly paying for itself. I was just spitballing an idea.
As stated in a number of observations this whole debate hinges on the heat loss/retention characteristics of the space you are attempting to heat. Far Infrared panels are something quite different and a challenge to appreciate unless you have taken time to evaluate by actually using them. The nature of them is to heat the body/objects and the fabric of the room which in turn over a longer period will radiate that heat back within the room. They are quite a bit different to the glowing infrared bar heaters that we have seen for patio and church halls.
This whole heating cost dilemma that we are now having to address is refocusing attention on the better conservation of energy such that the input can be minimised. The passivhaus model attempts to create the air tight, heat tight home by maximising the insulation but as a consequence requires an MVHR (mechanical ventilation heat recovery) system to prevent the property from filling up with condensation and black mould. Those that have gone to this model allegedly are benefiting from lower running costs.
Gas cost per KWh is cheaper than electric in a straight price comparison. However, I for one would like to see this topic updated and product options and attention given to the smart application of smart thermostats and insulation. Maybe this is beyond the scope of eFIXX who do a Stirling job of keeping us posted on things electric even if they can be at times manufacturer biased😲😀
Given recent skyrocketing oil and gas prices, would electric heating utilising off peak electricity and a home electric battery storage system now be more cost effective than gas or oil central heating?
Gas is *not* being phased out. Just a suggestion. There is also a suggestion of using the extensive gas distribution pipework for hydrogen burning domestic appliances. The city of Leeds was suggested as a trial.
Electricity is the future. What will make it feasible is PV panels and Powerwall types of batteries. Of course backed up by superinsulated homes, not needing much heat input to start with.
Thanks for the clarification - lots going on in the Northern Powergrid DNO area.
Economical heating from 3 Volts: ua-cam.com/video/v4HXKnTmyt4/v-deo.html
Electric heating is expensive. May be OK for one heater in one room, but to think about a house running on electric heaters - wow! I can't imagine the bill for this!
This video really needs updating regarding costs 😂😂
there is almost no difference in the energy used, the only difference is how quick they warm the room up. heaters are 100% efficient at what they do as they waste no energy (wasted energy is heat) a 2kw heater is a 2kw heater no matter what form. the most cost effective are fan and convector heaters as they give full heat instantly so lose less through natural heat loss through walls and ceilings while wasting time heating oil or such.
It's surprising how this simple principle of 100% efficiency is not understood by most people. It gets a bit more complicated when you start thinking about the differences between forced air, convection and radiating heaters. Infra-red halogen or a radiating panel might be more useful where the room isn't insulated very well, or when you need outdoor heating. The heat from an infra-red lamp shining on your face or hands can be much quicker than a fan heater, especially if you have just come home from the rain and moving air will draw heat away from your skin as latent heat of vaporisation. For water this loss is 2.3kJ/g.
We all often directly compare gas and electricity systems based upon price per kW of energy. Perhaps we should also take gas system losses into account. For example, flue gas heat loss, combustion heat exchanger efficiency, loss through copper pipes in floor voids and loft etc, standing charges for gas connection, boiler annual maintenance and repair, etc. I suspect that when you add all these "hidden costs" on to a gas system it might not be so compelling. Then add in the moral aspect due to climate change and electric heating really does start to stack up. My house is electrically heated with modern oil filled rads and I would never go back to gas fired central heating. My hot water is also electrically heated in an unvented cylinder - loads of hot water at towns mains pressure, just perfect!
It is something hard to compare. But a plug in/electric heater in a single room (especially a small room like a bedroom) you'd expect would be a lot cheaper to run than a gas boiler doing the whole house, which needs gas AND electricity to run. But electric through the whole house would cost loads.
But then you don't need to service an electric heater and it's unlikely to go wrong, so that needs to be factored in as well. Gas prices are likely to only go up now too.
@@BlatentlyFakeName good point about the electrical consumption of the gas boiler. Totally forgot about that.
@@JJ-zg1hh
Out of interest what is your annual kwh usage for your electrically heated house?
I use something like 35k kwh of gas each year and I fail to see how electric could be remotely cost effective.
Did I read somewhere that Rointe heaters use a technology where the power to the element is switched on and off repeatedly, thus claiming to use / consume less power overall. Apparently by switching on and off at a very fast rate, the heating element can save as much as 40% in electricity costs.....is this true or just an advertising scam ?
Can't speak for Rointe but this Ascot heater from Premspec controls the current flow, actually adjusting it up and down instead of just being on at full power or off. Clever stuff.
Nice to see TLC sponsoring you guys.....I’ve used them since 1987.....they first introduced me to Wago’s back in the 90’s !!
Well then it's heat output is just 40% less.
You can't create energy from nothing!
DIMPLEX Q-RADS DO THIS ALSO AND HAVE BEEN AROUND FOR A WHILE. NICE
In almost all cases using "electric" heaters is the least efficient way of room heating. It does not matter how you control it; Getting a room from one temperature to a higher one will consume the same amount of electrical energy ("units" in your context) however you control/deliver that energy. I'm not impressed by the video.
I actually stated in the video that it's cheaper to use gas fired boilers and radiators, however gas won't last forever and with the rise of renewable energy sources the future of heating is electric, probably using a combination of direct heating and heat pumps. Thanks for watching.
What do you mean you’re not impressed?
He’s just answering a question about electric heaters, and he answered it. Saying oil radiators have a slight advantage with them being able to retain heat longer after it’s turned off, and with the thermostat settings.
wall heaters heat the wall brilliantly and most rads are on the wall. My elec oil filled rad is in the middle of the room and heats the air not the wall.
They do use a lot of power. I have a 1600 watt heater like this and if you run it for an hour it costs 50p and is completely ineffective, useless even. A 1000w fan heater works much better IMO.
Love a whiteboard....;)
Me too!
Electric is a licence to print money, for the energy suppliers.
Resistive heating Joules in = joules out. Theres no bettering that no matter the fancy labeling. The only improvement I see - all resistive heating should have an accurate readable dial in degC (or F)
And mandated to turn off above say 23C. That alone would subtract power stations
Surely controlling the temperature more accurately has to be a good thing though?
@@efixx could be, but I'd say first massive power saving would be an accurate readable thermostat, maxed at 23C.
Second to that : modulated control using SSR or the like. So approaching set point modulate to 50% or 25% etc.
Who wouldn't have electric everything given a choice? No clunky boiler which has to be maintained, no pipes full of water running all over your house with the potential for leaks, no messy hob to be cleaned in your kitchen. Let's face it burning gas is pretty archaic.
£30 a month british gas homecare agreement carbon monoxide danger etc agreed. I use elec oil filled now - only 1 in the flat - Im happy with it.
we need an update video
I’m here because of the gas hike 250% wholesale! Lol 😂
Don’t worry it will flow through to the electricity prices
When electricity prices drop to 10% of the current amount, it might be economical to heat houses this way. Can't see that happening...
No but gas is being phased out for new build homes in the UK from 2025.
It’s disingenuous to suggest gas is being phased out and replaced with resistive electric heating - its not.
@@efixx
New builds will be heavily insulated, so making electricity feasible as heat input is small. Also, no gas meter charges, which can add towards electricity bills overall.
But the rest of us have to live in poorly insulated and air leaky Victorian nonsense.
@@efixx That seems to be your mantra for everything! Does not detract from the fact that electricity is at least 4 times more expensive than gas.
That seems to be your mantra for everything! Doesn't detract from the fact that electricity is at least four times more expensive than gas. No way is the unit price of electricity ever going to decrease. The energy suppliers would never agree to it.
I am concerned as to where all this push for renewable heat will take us. The UK can and does experience a miserable climate even in early Spring and Autumn. Worst case scenario for people who live in off-grid homes in the future will be freezing in their own homes because they cannot afford to use their non-gas heating.
Missed point is it’s not working constantly 8 hours! I think in average it will run maximum half hour constant in each hour. That’s mean is you will consume 3kw average for 8 hours. Not bad at all guys! Make your math accordingly. If you put lower temperature in the the night it may even save you a bit more. Consider.
Electric heating is the most expensive. Compared to central gas, or radiators with water heated by gas.
Christ I’m now paying 32p per unit,being ripped of like millions of others 🤷
You now need at least 4 HO's kerbside to afford any heat these days.
Oil Filled Rad 600W - 6p per Hour
1500w - 14p per Hour
So two 600w rads are cheaper to run than one 1500w.
Interesting.
I like oil filled radiators. They don’t burn the air like others do , much comfortable to breathe inside a room
Central gas heating is cheaper compared with electric radiator heater
We stated that in the video didn't we? 🤔
That works out over £25 every four weeks for one heater. A 1 bedroom flat at minimum would have 4 heaters. Thats £100 every 4 weeks.
On gas when this video was produced, you could do the same with four radiators for £40 every four weeks.
A big difference. But electricity always going to be more expensive than every other fuel.
I live on my own and have a 1 bed flat. I would have to be insane to keep 4 heaters going. I have 1 oil filled rad 500W and keep it in the lounge by day and move it to the bedroom at night. At todays high prices on 10 hours a day usage my overall energy bill is £100 PM. No gas.
i unplug my heater when not in use, no current.
Geez. This must have been before the war broke out hahaha :D
Electricity price in July 2022 now 30p per kw
yes - so my 500w elec oil filled costs me 15p an hour to run. £1.50 a day. Happy with that.
It's funny that I live in a country without developed gas infrastructure. So we have to heat mostly on electricity which is expensive. We looked at countries that can use gas with envy, since of course - that's objectively the way that makes more sense. Creating electricity is expensive, and often burns materials, which means energy is ultimately wasted in conversion and transportation. But now, because of some delusional "leaders" that do not know where the electricity comes from, everyone is forced to use electricity, since supposedly it's more "green"... Well, after you have the electricity, sure, but how you actually produce it in a clean and effective way? Hint - no, wind mills and solar panels aren't the answer - first because they are not as effective, and second - they have their own environment issues... Nuclear is probably the best option, but instead of making this technology safer, they are shutting reactors, so people go into the woods to chop trees... I would believe electricity is the answer, IF countries were producing safer, cleaner and cheaper electricity. This is what you must do first... kind of obvious. They are doing the total opposite. Idiocracy...
I agree 100% with you . They are shutting down nuclear power stations because the oil I our cars that they are telling us is bad for the environment will have to be sold ! so they just going to use it to power our cars and homes still. Like Trump would say Fake News
£1.98 @ .33p per kWh which is average about now
The heat capacity of oil is lower than water.
This means that the ability to transfer heat is lower for an oil based electric oil filled radiator than an electric water filled radiator.
One way of settling this would be for you to do an experiment where you turn on over a period of several days one radiator of each type to see the amount of energy consumed.
Moreover, if a heat pump is an option, then either a water to air, air to air, or water to water heat pump might provide even more energy savings than either a water or an oil filled electric radiator.
This is due to the fact that a heat pump will extract heat from the cold energy in the middle of the winter, and in most cases it will deliver more than one unit of energy for every unit of energy consumed.
Some more interesting questions would be:
What heat systems are compatible with renewable energy?
What heat systems will be most efficient with renewable energy?
What is the lifetime cost ratio of invested heating equipment to heat delivered?
Here are some products worth investigating further:

40 cent p hout in the netherlands.
1) The whole point of an electric heater is to use a lot of electricity. That's literally their job and 2) You can't answer the question because by far the largest variable is room insulation
50 eurocents per 1000km now
in the Netherlands........ without taxes.
15p per unit....this video hasnt aged well xDDDD
Yeah most houses have in the region of 5 to 10 rads per property if not more!
£1.80 x 10
🤔 sounds like the future!! NOT!
We'll see, fossil fuels won't last forever and it's kit much longer till gas won't be installed to new build homes.
@@efixx That's why there are heatpumps: much more efficient.
True dat!
@@efixx I work for a local council in Scotland and we have pretty much stopped new gas installs and opting for electric heating or a boiler change if urgent.
We done a sheltered housing revamp that had gas communal heating so everyone paid a share. Changed to electric heating throughout the entire building! And I’m talking around 15 homes plus communal areas. The install costs alone were eye watering the cost to the tenant per month in electric costs are scary! 70 year old pensioners paying more in electricity for a 1 bed flat than what they were for a 3 bed semi! Every tenant is in debt with the electric company. There’s only two winners here and it’s not the council or the tenant.
Now 32p and going up another 78%. Absolutely NOT the future of heating🤔
I didn’t like the way you mixed amps and amps without explaining them both.
You need to re do this with todays prices of lecky and gas.
You are trying to flog us very expensive electric radiators (around 400 quid each) that will bankrupt most of us if ever we tried to heat our houses with them. Okay come 2025 and no gas its Hobson's choice but TBH other than what we might call 'spot heat' or 'instant small room warming' there isn't a viable alternative to gas that has been invented anywhere n this planet to date IMHO. May as well get a 2KW convector heater from Home Bargains like I did for 12 quid last winter, warms the room in no time whatsoever for a tenth of the purchase price.
it needs time to heat up. so .... you have 100 procent loss. . . the warmth is rolling out the same thing it needed to warm up.
without comparison against other heating methods it's not possible to understand the effectiveness of these? eg how many would you need for typical rooms ?
So it just seems like sales spin for electric heaters. Downvoted.
the thing about heaters: they are all efficient because the energy loss due to inefficiency is lost as heat.... actually does that make a panel heater nearly 100% efficient?
Edit: Fucksake didn't read comments before posting comment... ah well I guess I'm preaching to a choir.
Stupid and deceptive research, and cheap advertisement for electrical panels
1year later it's cheaper to use electric heaters than gas 😅
Is it? At 44p/kwh a 1.2kw heater, 8 hours a day in one room is costing us about £60 a month.
10.3p/kwh for gas would allow us to heat our entire 3 bed property for about £100/130 per month
