How Geothermal Works We all know that Salem homes are subjected to varying temperatures during the year. Some climates can see the extremities that summer and winter throw at us. There is a consistent source of temperature that you can utilize; just a few feet below 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 cumulated in the ground as heat. Our geothermal systems extract this heating potential using an earth loop system; harvesting this free heat for your home. This innovative technology uses the sun's heat that the earth has readily accumulated to condition your home or office. Geothermal Heating Utilizing the earth loop, a geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and delivers this warmed air through a traditional duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling During the cooling mode, cool, refreshing air is distributed through the house by reversing the heating process. Heat is not extracted, instead it is driven 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 technique as well.
