A deep well recirculates water to extract ambient Earth temperature (typically at 6 to 10 gallons per minute). Ambient earth temperature is much lower than peak summer air temperature. And, much higher than the lowest extreme Winter air temperature. Water is 25 times more thermally conductive than air, so it is much more efficient that an outside air heat pump, (which is useless when outside air temperature is below 40 degrees F). [...] [...] A geothermal heat pump uses ambient Earth temperature to improve SEER for heat and cooling.
