How does a geothermal system work to heat and cool my home or office?
While temperatures fluctuate quite a bit on the surface of the Earth with the change of seasons, approximately four to six feet below the Earth’s surface, temperatures remain consistent year-long because the Earth absorbs 47% of all of the heat and energy from the sun and stores it. A geothermal system is a series of interconnected loops that run from your home down through this temperate underground region. During the heating process, fluid such as water or antifreeze in the loops absorb heat from the earth and transfer it to a unit located in the home such as a conventional duct system or radiant heat system. For cooling, the same unit takes in hot air, and transfers it to the loop fluid, which journeys through the ground, is cooled, and returned to your home.
