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?
you are confusing efficiency with Coefficient of Performance. You can't talk about efficiency unless you take into account the contribution of the heat source.
