Pennsylvania, US, heating and cooling of residential house
In North America, the first installation of a geoKOAX probe was installed in Pennsylvania for a residential application. The system was designed to heat and cool the house and provide 100 percent of hot water – a safe and comfortable alternative to burning propane gas or other fossil fuels. Two 250-ft boreholes 35-ft apart were installed in series coupled with a Climate Master Trilogy heat pump. Pairing the geoKOAX probes with a variable speed heat pump provides an impressive coefficient of performance of 5.5 and a significant reduction of electric consumption compared to conventional heating or cooling systems.
