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?

A heat pump doesn’t create heat. It moves it.

It consumes energy to move heat from one area to another. It just so happens that if you get a system with lots of heat in one area it doesnt actually take much energy to move that heat somewhere else, and can look like an efficiency greater than 1.
