- dredmorbius 3y agoHeat pumps achieve greater thermal output than the input energy, unlike electric resistance heating. The latter is 100% efficient (all energy in is delivered as heat). Heat pumps exceed 100% efficiency, and can deliver 3 to 6 times the heat energy as input, as they are moving heat from the exterior environment to the heated space.
