Heat without fuel
Closed-loop geothermal heating and cooling systems do not burn any fuel and do not pollute the air. “We’re just absorbing the heat from underground”, says Richard Sansoucy.
A closed-loop geothermal system has two sealed, interconnected pipes that go deep into the ground where natural heat is present. The pipes are installed through a process much like boring into the ground to install a well. Mr. Sansoucy said his system goes 300 feet down.
The system’s pipes carry water and environmentally safe antifreeze or some other suitable liquid. The earth’s heat warms the liquid and a pump circulates it through a duct system inside the house.
