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?

It doesn’t take much energy to pump gasoline, and yet it powers your car to travel vast distances. That’s similar to what a heat pump does. It isn’t creating heat, just moving it around. Since it’s relatively easy to move heat, you can move a huge amount of heat around without using that much energy.
