How is it that a machine (like a heat pump) can consume 1kw of power and produce an amount greater than that of heat? What am I misunderstanding?

Its not generating the heat by itself, its just yanking it from somewhere, usually from outside or in your house, and putting it somewhere else, usually outside or in your house.

It turns out that, with the right materials (refrigerant) the amount of energy it takes to pump that heat from where you don’t want to to where you do is a lot less than the heat you’re moving.
