The heat pump requires power to run, the question is whether the power to run the heap pump is smaller than the power required to just generate the same heat differential directly.
- jjk166 6y agoNo, the question is whether the power to run the heat pump is smaller than the additional power you'd gain by increasing the differential, which is always no. You would always get more energy out of draining the whole 60 foot water tank directly to ground than you would by lifting the water to 61 feet and then draining it to ground.
