Maybe that’s a little low, but you get the drift. Payback on our system was about four years.
Compared to a traditional nat gas system, our geothermal is 300 percent efficient. If you plan to build new, it will pay you back big time.
I don’t think I can build one here in Florida. The water table is about 2 feet down but thats not too cold. The aquifer certain has a lot of cold water, 72 degrees but I’m pretty sure the state frowns on a bunch of people drilling into it.
