Hi all, Any info would be very appreciated. We are in the infant stage of this whole geo installation, since our house won't be built until this summer (at the earliest). I am currently under the impression that an open-loop system using well water has cheaper start-up costs than installing a closed-loop system, and we just had our well drilled that seems more than adequate for it, but I have a few concerns. I apologize if these are embarrassingly rookie questions. My main concerns are what to do with the water after it runs through the geo (seems to me that having to drill a re-injection well would end-up costing much more than just digging a horizontal closed-loop), and what effects water hardness and other well water impurities will having on the life of the geo (I don't yet have any idea what the quality of the water is). Thanks very much for any help.
