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’s just like your fridge.. the heatpump in there, takes the heat energy from your fridge, and takes it out. So the fridge stays cold, and the surrounding air in the kitchen heats up. The fridge does consume energy but generally less than the heat energy that is being moved. Heat pumps for home heating work on the same principle. It takes heat energy from an external source (outside air, or geothermal, or surface water) and transports that to inside. If it uses 1kwh electrical to transport 5kwh of heat energy the COP is 5.
