How Geothermal Works We all know that Martinsburg 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 consistent source of temperature that you can utilize; just a few feet below the earth's surface. How is that possible? The sun instills the Earth's crust with its heat energy. Forty-seven percent of that energy is stored in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; collecting this free heat for your home. This cutting-edge technology uses the sun's heat that the earth has readily stored to condition your home or office. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump employs the earth loop system to draw the heat from the ground. With delivery through a traditional duct system, the geothermal system pulls heat from the loops and distributes it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling During the cooling mode, cool, refreshing air is circulated throughout the house by doing the exact opposite as the heating process. Heat is not pulled, instead it is pushed into the ground. The warm heat is extracted from your home and taken back into the earth loop. Your hot water heating can be fueled by this procedure as well.
