Is there such a thing? I need one of these babies in my spare room, heating has cut out there and am looking for something cost effective as a temporary solution. The fan heaters I've looked at are rated in kW which is ridiculous, anyone recommend something a little "greener"?
 
I cant see how one would be any efficient thinking about it.

Wasted energy is usually heat on appliances, given thats what you want in a heater they'd all be the same wouldn't they?

I'm running a halogen heater in the living room right now, 1200w on full blast, keeps the room nice and snug.
 
There is such a thing. Well, sort of.

It's not so much the amount of heat, but how it's circulated that matters. Heat is no use to you if it's in the wrong place, or concentrated at one end of the room while the other end of the room is cold.

GCSE physics keywords - condunction, convection, and radiation (Google if you don't understand the difference).
 
From what I've read, the cheapest method of heating a single room is a gas fire. Obviously, if you have to heat the entire house, then Gas Central Heating wins.
 
We're on Economy 10 heating which is fine for most of our needs and not too expensive to run as the storage panels are all new and energy efficient. I find though with being at home all day I can get a little cold during the early afternoon so bought one of these. They have settings from 400w to 1200w and very good at warming up small areas without costing too much on the lower setting. They also give off a bright light making the room feel very warm and sunny. Halogen heater

[Edit] Just checked for running cost and they use 1 unit per hour when on full setting of 1200w, I usually have mine on the lowest of the 3 settings using 1/3 of a unit per hour or 400 watts so check how much per unit your paying for your electric and this will give you the running cost, they can also be run through a timer switch set to turn on/off at regular intervals.

Electric heaters are all 100% efficient. Every joule goes to heating the room. The ones that blow out air warm up the room quickest, but they are loud. A benefit is that you don't need to keep it on for that long to get a room warm at all.

100%? Some breakthrough we've not heard about then :p

The "wasted" energy goes to heating the room? I asked my physics teacher if there was anything that is 100% efficient last year, and that was the answer and reasoning he gave.

Edit: this doesn't apply to the ones that blow obviously. Only the ones that are like the heaters on walls.

Don't worry about it in general, you get used to not having heating easy, I never had it when I was a lad til I was about 16, you don't really notice it's not there unless the rest of the house is toasty.

My mate owns the Gas Company where OCUK is.
He has commented for years whenever he sees our gas fire on that we are wasting so much energy.
He kept on saying that a new maxi boiler and new radiators would mean that we could heat the whole house with less gas than we use on the fire alone.
I thought he was talking BS but the house is now always warm and we've never had the fire on.
Our old central heating was so inneficient.
We haven't had the first bill yet but we can tell by the readings its going to be well lower.

The heaters may be efficient but the insulation in the room isn't.
Heat will always find the cold and hot air rises to the ceiling.
I always wondered why my ceiling fans went in reverse until I was told it was to put them on slow so they would blow the hot air back down.

Eh? It will also apply to the ones that blow, since the energy consumed will be converted to heat. Unless you can tell me where the energy that was "used" goes to besides heat.
 
Probably no use as a temporary measure but underfloor heating is the most efficient and comfortable means of heating. I can only suggest a normal stading heater but with variable settings so you can regulate it.
