Size guide

Choose the radiator by the size of the room it will heat. Use the calculator below, or the quick table. The figures assume a typical UK room with modern insulation and a 2.4 m ceiling. For a conservatory, a room with large windows or a draughty older room, choose the next size up: a larger radiator reaches temperature sooner and then cycles off for longer.

Size guide

Which size electric radiator do I need?

Measure the room, pick the insulation that sounds most like your home, and we will suggest the output. If you are between sizes, go up: a larger radiator reaches temperature sooner and cycles off for longer.

FAQs

Sizing questions

Are ceramic core electric radiators expensive to run?

Any electric heater turns 1 kWh of electricity into 1 kWh of heat, so the running cost is set by the output you choose and the hours it runs at full power. The ceramic core keeps radiating after the thermostat switches the element off, so the element runs for fewer hours than the radiator is on. Use the running-cost calculator above with your own unit rate.

Can I fit it myself?

The 1000W and 1500W come with a fitted UK plug and a wall bracket: fix the bracket, hang the radiator, plug in. The 2000W has no plug and must be hardwired to a fused spur by a qualified electrician.

What if it is not right for my room?

You have 30 days to return it. Every radiator also carries a 2-year warranty covering parts and electronics.
