If a subdivision, i.e. 400 homes, were to use geothermal technology, both for heating and cooling, assuming 45 degrees north in the midwest United States, and assuming a substantial aquafer exists, (note, solar heating, and cooling, using Stirling technology), how much will the ground water change temperature…(not a trick question……seriously)… if 1 person does it, it’s a good idea…..if everyone does it, is it still a good idea?
Note, assume 50-65 degree F ground water temperature.
