This is a common thread on heat pump threads, where numbers like 300% efficiency are quoted. The explanation, as I understand it, is that it’s not creating 3 or 4 kW of heat for each kW of power drawn: it’s moving those 3 or 4 kW from outside to inside (or vice versa when cooling instead of warming).
