Buying decision

Which type of heater is right for you?

Every electric heater turns a kilowatt into the same amount of heat — what changes is how fast you feel it, how long it lasts and how it sounds.

Common questions

Heating questions, answered

What size space heater do I need?

Allow roughly 10 watts per square foot for a room with average insulation and 8-foot ceilings, so a standard 1,500 W heater suits about 150 sq ft. Add 20–30% for high ceilings, single glazing or a room above a garage.

How much does it cost to run a space heater?

Multiply the wattage in kilowatts by the hours you run it and your electricity price. A 1,500 W heater used 5 hours a day at $0.17 per kWh costs about $1.28 a day — roughly $38 a month.

Is an oil-filled radiator cheaper to run than a ceramic heater?

Watt for watt, every electric heater turns the same electricity into the same heat. Oil-filled radiators feel cheaper in a closed room because they keep radiating after the thermostat clicks off and cycle less; ceramic heaters are better for short bursts of fast heat.

What is the cheapest way to stay warm at home?

Stop drafts first, then heat the person rather than the whole house. Door and window draft-proofing, thermal curtains and a heated blanket — which uses around a tenth of the power of a space heater — cut costs more than turning up the thermostat.
