How Geothermal Works We all know that Michiana homes are acceptable 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 put to good use; just a few feet beneath 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 cumulated in the ground as heat. WaterFurnace 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 stored to condition your home or office. Geothermal Heating During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be put to use for a radiant floor system or domestic hot water heating. Geothermal Cooling During the cooling mode, cold, conditioned air is distributed through 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 procedure as well.
