Free standing electric radiators.

Can anyone help with advice on electricity consumption supplied by a free standing electric radiator 2000w. Our house doesn't have any heating and we don't like fan heaters and wondered if they were fuel hogs. Sorry if I've posted on the wrong section - hopefully some kind soul will put me right. thank you.

You've posted the answer in your question.

a 2000w heater is also written as 2kWh, which means it will consume 2kW every hour that it is on full power. To work out the cost of running this simply multiply your unit cost (probably about 12p?) by 2 (kWh)= 24p per hour.

The cost will reduce as the thermostat turns the heater off when the room has reached temperature.

Thank you Andy for that reply - very helpful.

I don't know the technicalities but I remember when I was a student and had one of these and could watch the meter in the room go into a spinning overdrive when it was on. Maybe that was a more powerfull model.

Th type of electric heater make absolutely no difference. All electric heaters are 100% efficient, so a 2kW fan heater will cost exactly the same to run as a 2kW oil filled heater.
The way they release their heat is different, but not the output or the cost.

Some electric heaters (ceramic or oil-free) heat up and cool down v. quickly

Oil-filled heaters are much slower

The positioning of the heater is probably just as important as its power rating

As I said, the release of the heat can be slow (oil filled) or fast (fan heaters), but this makes no difference to the efficiency, the running costs, or the actual heat output.
An oil filled rad does not produce any more heat per kWh input of electricity, it just outputs it more slowly.

I would question the value of fan heaters. If you use a fan heater close to your body, then there is a chance that it will cool you rather than warm you as it pumps large quantities of fast-moving air across your skin.

But the air it projects is hot...

That does not necessarily mean that it will not become hotter as it takes heat away from your skin

It's a bit like the windchill factor

macman

But windchill factor is only relevant when the air is colder than the target it's hitting. The stream of cold air carries your body heat away, or rather it is heated by the heat loss from your body.
Having hot air blown in your face may feel unpleasant, but it won't cool you down.
