Low energy electric heaters

[bigbeautifulmonster]

Can anyone point me in the right direction to find a low energy, non fan (due to fans drying the air, I assume), constant temperature heater out there? I am just so overwhelmed and have little time to look into it properly. Or where should I go to ask someone? Eg. Curry's (though a lot of the time the people in my local don't know very much).

Our entire property is run on electric alone and bills are through the roof. Smart meter recently installed so I am pretty sure the main culprits are immersion heater, cooker and the wheelie oil heaters, two of which are in a large space (40sq m) that needs to maintain a constant temp and humidity due to what is in there.

Underfloor heating not a option.

A kilowatt is a kilowatt. There is no such thing as an electric heater that uses less energy to heat.
For constant heat you need a thermostat so then at least you are only using the minimum.

Oh really? So these 350w heaters out there are just junk/don't actually heat the room?

Yep. Some ir heaters heat surfaces and not the air but they still only put out the same heat they consume

Would I be better off with a massive high kw but thermostatic heater then?

I've just had a look and Dimplex do some. But I don't need all the 7day settings rubbish as it needs to be on all the time.

The oil filled heaters are a pretty good option for all-the-time heating. Their thermostats will keep it at the lowest possible ok temperature.

There are some out there with clay centres that take ages to cool once the thermostat turns them off. Are they worth looking into in order to avoid them using too much electricity?

Only if you're on economy 7 you heat them when rates are cheap.

following with interest as we're moving to a house with central heating except one room, which is an extension, where the only heating is a plug in oil filled radiator. I'm planning to use that room as my office so it needs to be warm enough to work in.

The obvious answer is to get rid of the —cannabis farm— whatever is in there.

I don’t think there is a way to have heating on 24/7 cheaply.

But of a strike out fail there

@EmmaGrundyForPM I would get a decent sleeping bag and sit in that! You will be toasty!

Came on to say what @boonducks said.

You can have more powerful heaters running intermittently, or less powerful heaters running constantly, but ultimately to heat a given space and its contents to a certain temperature and maintain it is going to require a certain amount of energy. It doesn't matter what type of heater you use; the energy requirement - and your electricity bill - is going to stay the same. And, to be blunt, 40m2 is a big space.

I'm not sure how widespread they are here, but ceramic heat wafers are an 'always on' thing which use little electricity, for little heat in return.

Loggia heaters coupled with a thermostat and 7-day timer programme may provide a more powerful solution if you have corners to fit them - they tend to be 500W.

It would be helpful if you could explain why it needs to be on all the time and must be non-fan. A directed air system will dry out a human being sitting in front of it because it will prompt more evaporation from the skin, but it wouldn't 'dry out' air or furniture unless it also dehumidified it.

An air-to-air heat pump may well be your most cost effective way of heating large spaces to a constant temperature (and would also cool it in the summer if constant temperature that that important) but it would dehumidify air.

I have a digital thermostatic plug, which allows me to set a temperature and then plug a heater into that. The heater's set on maximum with no thermostatic controls of its own and so is easily controllable by the plug which switches it on and off to keep the temperature constant.

There's quite a lot of them for sale on Amazon.

I have had a Timeguard one for years, but it does tend to misregister the temperature because it gets hot from the heater's current and so shuts off too soon. Next time I'll get one with a sensor probe!
