Buying Electric Radiators: Quick Tip

With electric radiators, think wattage and control. Choose the right wattage for your room size and insulation, then focus on features that stop you wasting electricity — a good thermostat, timer and programming make a bigger difference than most people expect. If it’s heating a room you only use sometimes, independent control is where electric radiators really shine.

Who Should Buy an Electric Radiator?

And who should consider alternatives

✔
Who Should Buy

Rooms without central heating pipework

Ideal if adding a wet radiator would be costly or disruptive. Electric radiators provide heat without a boiler connection.

People who want room-by-room heating control

Great for home offices, spare rooms and extensions where you only want to heat the space when it’s being used.

Homes needing quick upgrades without plumbing

Perfect if you want to improve heating in a room without changing your existing boiler system or running new pipes.

✘
Who Shouldn't Buy

You want the lowest-cost option for heating all day

If you have an efficient wet central heating system already, it may be cheaper to heat the home through the boiler rather than running electric heating for long periods.

You need to heat very large open-plan spaces

Large areas can require higher wattage or multiple units, which can increase running costs. A properly sized wet system setup may be more practical for big spaces.

Your electrical setup isn’t suitable

Some electric radiators need hardwiring or suitable circuits. If the electrics need upgrading, you may need an electrician before installing.

FAQs About Electric Radiators

Help with sizing, control and running

  • What are electric radiators?

    Electric radiators are heaters that warm a room using electricity rather than hot water from a boiler. They run from the mains supply and can be used as a primary heat source or as additional heating, especially in rooms where adding central heating pipework would be difficult.

  • How do I size an electric radiator properly?

    Electric radiators are sized in watts. The right wattage depends on room size, insulation, ceiling height and heat loss. A common starting point is roughly 80–120 watts per square metre, then adjust for draughts, big windows, or very well-insulated rooms to get a more accurate match.

  • What controls are worth paying for on an electric radiator?

    The most useful features are a precise thermostat, a timer, and programmable schedules so the radiator only runs when needed. If you want more control, some models offer app control or zoning so you can set different temperatures in different rooms and avoid wasting energy.
