FAQ
Are electric wall heaters efficient?
They’re 100% efficient at converting electricity to heat — but 1 kWh of electricity delivers 1 kWh of heat. A heat pump delivers 2.5-3.5 kWh of heat per kWh of electricity by moving outdoor air, so the same warmth costs a fraction as much.
Should I keep my wall heater on low all day?
Setting back the thermostat when nobody’s home always saves. Wall heaters heat quickly enough (unlike heat pumps) that recovery time isn’t an issue.
Is 1,500W standard?
Yes for a plug-in / 120V circuit. Hardwired 240V wall heaters can go 2,000-4,000W for larger spaces.
