How an Earth Loop System Works:
A geothermal heating & cooling system taps into the earth’s stored energy by using a series of buried high-density polyethylene pipes referred to as the earth loop system. The polyethylene pipe is not glued together. It is actually “heat fused” together so that it becomes one continuous pipe. This type of loop system is considered a closed loop system. It typically comes with a 50-year manufacturer’s warranty.
