Introduction
Geothermal pipes transfer heat from the ground into a building to provide space heating and preheat domestic hot water. Geothermal heat exchange is a clean energy method for heating and cooling commercial and residential buildings. This technology has been proven effective and widely applied for decades.
In simplest terms, HDPE pipes are buried underground, enabling energy transfer between the fluid inside the pipes and the earth. The fluid in the pipes is warmed in winter and cooled in summer. The entire system consists of buried HDPE pipes, a heat pump, and an air distribution system.
Factory visits and third-party inspections are welcome.
