GHP Open-Loop Systems

GHP geothermal heat pump Open-Loop System

This type of GHPS uses well(s) or surface body water as the heat exchange fluid that circulates directly through the Geothermal heat pump system (GHP). Once it has circulated through the system, the water returns to the ground through the well, a recharge well, or surface discharge. This option is obviously practical only where there is an adequate supply of relatively clean water, and all local codes and regulations regarding groundwater discharge are met.
