      We are looking to install a closed loop geothermal heat pump exchange in our old home. So far, we have narrowed the field of manufacturers to three; Trane, Water Furnace and Bard. Anyone have any good or bad experiences with any of these? Or any others we

      should consider? Private e-mail appreciated. I will summarize responses here. Thanks.

      We are in our 2nd home with GWHP. Used Marvair brand and have had much success. I have only used the open system with a return well.

      We find the operation costs quite competitive and a savings.
