What size electric radiator do i need?

This will depend primarily on the size of the room you wish to heat. As a rough rule of thumb, take the size of your room in square metres and multiply it by 100. This will give you the total wattage needed to comfortably heat your space, and this can be split between one or more radiators as needed.

For those of you who prefer working in feet and inches, you should look for approximately 10 Watts per square foot of space.

How much does an electric radiator cost to run?

This is quite easy to work out if you know two pieces of information. First of all you need to know the Wattage of your radiator, secondly you will need to know how much you pay your electricity supplier per kWh (Killowat-Hour). If you’re unsure, you can use a rough estimate of 15p per kWh (correct as of November 2015).

This means for a 1000W electric radiator you’d be paying around 15p per hour of heating. A 500W radiator would cost just 7p per hour. Whereas a 2000W radiator would cost 30p per hour, and so on. Of course, there is more to an economical heater than simply the wattage.

Should i upgrade from a storage heater?

This is a tricky one, storage heaters and the old economy 7 tariff are a legacy left over from when Britain was predominately powered by coal fired power stations. As Nuclear and increasingly more so, renewable power, becomes the norm this old tariff is looking out of date.

That said, cost wise there is little difference as such, however you may find that storage heaters are somewhat impractical and can’t provide the heat on demand that electric radiators or gas central heating can. It is here that you will see the most benefit.

Are wall mounted or free standing radiators best?

This depends on how you define best. A properly fitted wall mounted radiator will be the most efficient as it can effectively use convection heating to evenly heat the room. However in terms of heat output there is little difference. So essentially the question is whether you wish to have the added portability of a free standing unit or the neatness of a wall mounted unit.

What is the difference between an expensive 1000 Watt radiator and a cheap 1000 Watt radiator?

This might surprise you but in terms of heat production, there is no difference at all. The difference in price will account for range of features and the quality of build. A cheap and nasty radiator may well produce the same heat as a more expensive model but if it falls apart or breaks down in 6 months well, then that’s not such good value for money.

On the other hand, just because a radiator is super expensive it does not necessarily mean it’s build quality is equally as high. This is why we’ve hand picked the best and most respected radiators for inclusion on our comparison chart here.

My radiator is making a clicking sound, what is it?

Most electric radiators will make a clicking sound when powered on as the thermostat clicks into life. However, a common problem on such devices is a constant clicking sound whilst the unit is running. This could be relatively harmless, or in worst cases a possible sign that the thermostat is having problems and could be on it’s way to failing. If you’re worried about such a noise we advise contacting a registered heating specialist to come out and take a look at your radiator to ensure peace of mind.
