Geothermal vs. air-source heat pump
I am building a tight insulated home in zone 6 and deciding wether to choose between ground water heat pump and air heat pump. After the 30% tax incentive there is not much increse in cost for the geo system. I am being told differnet stories in regard to system performance and longevity of equipment ( depending on what side of the fence your on). I am hoping to be in this house for the duration and willl be the last home I live in until my kids have to make the choice of where to send me. Dana
