WebMost electric heaters have a maximum rated output – usually 2,000 watts (2kW) or 3,000 watts (3kW). Most heaters also have settings where you can adjust heat output – the more choices, the more control you have over getting the correct temperature without using too much energy. ... if you use a 2kW fan heater for an hour every morning and ... WebDec 18, 2024 · It's pretty much 100% efficient at converting electric energy into heat energy. (vs. a heat pump being about 300% efficient 1, moving existing heat from outdoors as well). Even a lightbulb that turns some power into visible light will ultimately heat the room when that light is absorbed by the walls. (Unless some light escapes out windows).
