A "heat pump" in this context is a device that uses a refrigeration cycle to extract heat from outside and move it inside. An A/C running in reverse, essentially. And heat pumps are vastly more efficient than resistive heating (or using the heat from a microchip). In many places, for every 1W of power a heat pump consumes, it can move 4W or more of heat into the space. |
