Geothermal
We have 400' of 1/2 oxygen-barrier Pex-B buried ~34" down in our back yard. We plan to use it to dump excess heat in the summer, and for "passive" air conditioning, but not for running a geothermal heat pump for supplemental heating. Why not? *NOTE* These calculations are *incorrect*; divide the cost of gas by 3 to arrive at the maximum "breakeven" gas cost (about $5.81/gJ, if electricity is $0.07/kWH).
