Geothermal Savings Calculators
If you have a geothermal heat pump, were the geothermal savings calculators an accurate reflection of the savings you saw from switching to geothermal? My home is about 4200 sq. ft. and we have a three zone oil fired boiler system now. The geothermal contractor recommends two 3 ton units and one 2 ton unit. They are recommending keeping the oil as a backup and to heat water. They also happen to supply our oil so I am wondering if this is for our benefit or theirs. Any thoughts?
