Anybody here running a geothermal closed or open loop heat pump?
If so, what was your total cost? Including supplies, digging, installation, and miscellaneous expenses.
My parents have been looking into either solar heating or geothermal heating/cooling for our home. It would be a retrofit, and will certainly be very costly. Regardless, I've run the #'s with a variety of payoff periods and they are all quite short (relatively speaking). By the time my parents are ready for retirement, any system will have been paid off, convenient. We have a contractor coming tomorrow to give us a quote. I'm curious to know what other's have experienced though.
My gut feeling is 20,000 dollars.
