How Geothermal Works We all know that Mt. Pleasant homes are subjected to varying temperatures throughout the year. Some climates can see the extremes that summer and winter hit us with. There is a dependable source of temperature that you can put to good use; just a few feet under the earth's surface. How is that possible? The sun infuses the Earth's crust with its heat energy. Forty-seven percent of that energy is stockpiled in the ground as heat. WaterFurnace geothermal systems tap this heating potential using an earth loop system; harvesting this free heat for your home. This state-of-the-art technology uses the sun's heat that the earth has readily accumulated to condition your home or office. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump utilizes the earth loop system to extract the heat from the ground. With delivery through a standard duct system, the geothermal system pulls heat from the loops and circulates it as warm air. Options are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling During the cooling mode, cold, conditioned air is distributed throughout the house by reversing the heating process. Heat is not pulled, instead it is propelled into the ground. The warm heat is extracted from your home and moved back into the earth loop. Your hot water heating can be fueled by this process as well.
