Geothermal Heating Installation

Installation Process for Geothermal Heating Systems

The installation process for geothermal heating systems involves several steps. First, a site survey is performed to determine the suitability of the location for installation. Then, the ground is excavated to create a trench or borehole. A ground loop is then installed in the trench or borehole, which consists of a series of pipes that circulate a heat transfer fluid to capture the earth’s warmth. Next, a heat pump is installed inside the home to translate the collected heat into usable heat for the HVAC system. Finally, the HVAC system is integrated with the geothermal system to distribute the heat throughout the home.

Equipment and Modifications for Home’s Heating System

The installation of a geothermal heating system requires specific equipment and modifications to a home’s heating system. The necessary equipment includes a ground loop system, a geothermal heat pump, and an HVAC system. The ground loop system consists of pipes, often made of high-density polyethylene (HDPE), that are plowed or drilled into the earth to capture the earth’s heat. The geothermal heat pump translates the heat from the ground loop into usable heat for the HVAC system. Finally, modifications may be needed to the ductwork of an existing HVAC system to ensure compatibility and to distribute the heat throughout the home effectively. Additional steps may be needed for new construction installations.
