Let me put it this way: if you have 1000 watts to put into heating, and you use a calrod (or other type of resistive heater), you will get about 1000 watts of heat. That's about 100% efficiency. Now suppose you put that 1000 watts into a heat pump and get 3000 watts of heat out of it, what is the efficiency of the heat pump?
