WebJul 27, 2012 · Greater than 100' is a good rule of thumb. Spacing of vertical boreholes is site specific as well - but usually in the 10-20' range depending on availability of land. urthbuoy, Jul 25, 2012. #5. DavidCraig Member. Your are referring to a minimum requirement for spacing on a open loop. Thinking of closed loops actually. WebThe geothermal earth loop, or ground heat exchanger (GHEX), is the heart and soul of a geothermal heat pump (GHP) system. It is where heat is extracted from the earth to provide geothermal heating in winter–and where heat is rejected to provide cooling in summer–utilizing an underground piping system, which usually consists of a specified ...
