    If you’ve ever used an air conditioner you’ve used a heat pump. ACs are just one way heat pumps that take heat from inside and dump it outside. You can add a “reversing valve” to allow it to move heat in either direction, making a general purpose “heat pump”. They can be nearly 400% efficient, which is better than any other heat source.
