Recommendations for Geothermal Heating and Cooling Systems

Geothermal heating and cooling uses the relatively constant temperature of the earth to heat and cool homes and businesses with 40 to 70 percent less energy than conventional systems. In winter, the relative warmth from the ground or ground water is transferred to the building, and in summer the process is reversed and the heat of the building is transferred to the earth or ground water. This document is intended for use by state and local government agencies and for the geothermal heating and cooling industry to use in overseeing the installation, operation, and decommissioning of these systems. The recommendations are intended to help ensure that geothermal heating and cooling systems are installed in a manner that will prevent ground water contamination, will protect drinking water sources and public health, and help protect the owner’s investments.
