The 10 Best Fan Heaters of 2026, Ranked

Cost per hour is the heater's kilowatts times your unit price. A 2kW heater on full power uses 2kWh an hour, so at an example 27p per kWh it costs 54p an hour; check your own tariff, as unit prices change. A thermostat cuts this by switching the element off once the room is warm, so the real cost is lower in a small, well-insulated space.

The air warms quickly but cools quickly once the heater is off, so they suit short top-ups and not all-day heating. The fan is noisy on cheaper models, around 57dB on the loudest here, and the air can feel dry. Like any electric heater, a fan heater costs its kilowatts times your unit price for every hour it runs, so a 2kW model left on for hours adds up quickly.

A 2kW heater suits a small room of up to about 10 to 20 square metres. A rough guide is 100W per square metre, so treat a fan heater as a top-up rather than whole-room heating. A 3kW model suits a larger room.

A ceramic (PTC) element reaches heat quickly, has less smell when it first warms up, and shuts itself down as it overheats. A plain metal coil heats quickly too but can smell of burnt dust and glow. Noise comes mostly from the fan, so a ceramic heater is not automatically quieter.

A fan heater warms a small room in minutes but cools fast once switched off. An oil-filled radiator takes longer but gives steady, silent warmth that lingers, so it suits a bedroom or all-day use; see our [oil-filled radiators guide](/home/electric-heaters/oil-filled-radiators/). Convector heaters are a third type, and our [electric heaters hub](/home/electric-heaters/) explains which type fits your room.

No. Do not leave any fan heater running unattended or while you sleep. Look for a tip-over cut-out and overheat protection, keep it clear of curtains and bedding, and never dry clothes on it. Only use a heater with a suitable IP rating in a bathroom, and keep ordinary models out of wet zones.
