Do electric fires give off much heat?

A cold winter night, darkness fell early even before you got home. The house is cold, and you want to get warm quickly. You get settled in, turn on the TV, turn on the fire, but wait… It is an electric fire. Does this electric fire give off heat? Will it be able to warm the room?

Well, that is what we are going to discover today.


As well as looking stunning, and transforming the rooms they are in, our electric fires do give off a lot of heat. Many have different levels of heat for you to choose, so whether it is to warm a really cold room or just keep the temperature ticking along nicely, you can decide. This feature does give the electric fireplaces an edge on their traditional solid fuel and gas fires.

The heat is instantaneous, and it is also significantly more efficient than gas, coal or solid fuel fires. With these other fires, a lot of the energy produced by the fuel when burnt disappears straight up the chimney. This lost energy is significant as the vertical chimney is where most of the heat goes – as we know, heat rises. As well as this, the traditional fuels also leave behind a lot of mess, definitely something to consider. This is not a concern to the flueless electric fires that are 100% efficient and produce heat the moment they are switched on; leaving no nasty residue or ash/soot behind.

Another factor to consider with electric fireplaces, is their reliability. They are consistent every time you use them, as there is no difference in the ‘quality’ of electric used to power them. The National Grid does not have bad days where the electricity is dirty, or wet – two big problems for solid fuels and coal. On demand, the electric fireplaces work to heat your room and provide comfort to you.

Talking about consistency, the other feature of electric fires is that their delivery does not change, unless you choose to turn down the fire. Just as there is no difference in the electricity provided to the fire, the unit will produce the same level of heat from the moment you switch it on until you turn it off. The electric fires will provide the heat at a constant level until you decide to change the temperature or no longer the fire on.

There is no period of dwindling heat, or having to retrieve more fuel for the fire – it comes through the plug socket in your wall.

One type of heat that your electric fireplace will not generate, is radiant heat. This is the heat that builds up in materials, such as the glass front on a gas fire, or the cast iron grate of a coal fire. This radiant energy is stored as the heat is ‘radiated’ from the source, but as electric fires do heat an element within the fire and do not produce a ‘real’ flame, they do not produce this radiant heat. This is perhaps a double-edged sword, as the benefit of not having a piping hot glass plate or metal surround become pretty obvious when we think about small children or pets being in close proximity to them. The electric fireplaces massively reduce the risk of burns.

“Ok, ok, that’s all great. But how much heat do they give off?”

Well, that depends on which unit you get. Some fires have options for 500 watts, 750w, 1kilowatt, 1.5kw and up to 2kw. This upper limit is dictated by the voltage that comes into a domestic property.

Fireplaces between 1kw and 1.5kw will produce up to 4,500 BTUs (the British Thermal Unit – how heating capacity is measured) and this should be more than enough to heat a small to medium room. If you have a larger living area that you would like the fire in, then a 2kw fireplace would be a great fit. A 2kw unit can generate up to 8,000 BTUs which can comfortably add cosy heat to a 400 square feet room.

So, hopefully that answers the question, does an electric fireplace generate much heat? If you would like to peruse our range, you can find our electric fireplaces here and our marble suites here.
