Heater type

Expand to view more details.

Radiant heaters are personal heaters. They radiate heat from a red-hot heating element. Convection and panel heaters draw cold air over an electric heating element. The warmed air then leaves the heater and rises towards the ceiling, while cooler air moves in to replace it. This includes oil filled column heaters. Fan heaters are specifically designed to blow hot air; the fan is a key part of the heater design, rather than a booster as on other heater types. Their fans are usually more powerful and can project the hot air a reasonable distance into the room.

Design type

Expand to view more details.

Heaters come in all shapes and sizes, but generally conform to type. If you see elements like 'ceramic' or 'micathermic' we've found these aren't guaranteed to give better results than other formats, so tend to fall into the marketing spin category. We list the common forms seen here, such as oil columns, towers, panel heaters, fan heaters and radiant heaters.
