I am going tohave house built this year and one of the many things throwing around is goingwith geothermal. Seems that everyone talk to has their opinion. theheating companies are all for it. But seems that friends and other tradespeople that talk to about it are down on the long term payback. I knowabout the tax credits, can’t help but know way the heating companies keepreminding me of it. just wondering if anyone converted existing houseover to geothermal and has some savings numbers. House will have full basement with about 1600square feet min floor. From Wisconsin so do get some colddays..
