The KUPP Geothermal (Spacer) PE pipe is becoming commoditized in Geothermal Heating and Cooling System. HDPE Pipe is considered for the top of geothermal piping. It is essentially higher-grade version of polyethylene pipe, with better rigidity, thermal properties, and chemical resistance. This piping system (geothermal heat pumps & exchanger) can tap into this resource to heat and cooling buildings. In the winter, the heat pump removes heat from the heat exchanger and pumps it into the indoor air delivery system. In the summer, the process is reversed, and heat pump moves heat from the indoor air into the heat exchanger.
