- TheSpiceIsLife 10y agoModern heat pumps are three to four times more efficient in their use of electric power than simple electrical resistance heaters.[1] I have a 7.1kW heat pump, it uses a little over 1.79kW of power generate that heat, so a thermal efficiency of 3.96:1. Any light bulb, whether it's incandescent or CFL or LED produces heat a 1:1 thermal efficiency. 1. https://en.wikipedia.org/wiki/Heat_pump https://en.wikipedia.org/wiki/Heat_pump
