Here my grid tied solar PV system has done well, in part because a modern air to air heat pump efficiently
converts my KWH reserve into house heat/cooling. Not much invested in the pump, but the trade off is
switching to resistance or propane for the most sever cold periods. A trenched in geo thermal heat pump
can handle more extreme temps, at least until it freezes its heat sink dirt.
One method mentioned has been a dual well system; bring water up one, send it back down the other. This
sounds like a big expense, and what are the implications if drinking water is coming from this system? The
thought I just had, was run a water line to my neighbors, and we share our 2 existing wells. When flow is
needed either could turn on a pump, and we could reverse the system periodically to keep things evened
out. Maybe the very first issue is a one way valve at the pump, but perhaps a return pipe could be added
at the top. thoughts? Bruce Roe
