As the outdoor temperature moves away from the indoor and ground temperature, direct heat transfer with the groundwater becomes the best power saving option. Running a radiator to temper the outdoor air will not grab as much heat. However, if you use a low power pump to supply it you might save more watts than by using a well pump.

So if i used a radiator it wouldnt lower the temp enough to matter ?
