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?

Heat is extracted from the cold side. Because this is against the natural flow of hot to cold, energy is required to get the heat pump’s cold side cold enough to be warmed by the surroundings.
The power required to run the heat pump is used to work against the natural flow of heat from the hot side to cold side.
