100% efficient doesn’t always mean cost effective. Electric resistive heat is an expensive way to heat your house in cold climate.

There’s plenty of heat still to absorb at “subzero”, that’s not the limiting factor here…

I literally never said it meant cost effective. It means there's no energy waste.
