How Geothermal Works We all know that Michigan homes are subjected to varying temperatures throughout the year. Some climates can see the extremes 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 underneath the earth's surface. How is that possible? The sun permeates 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; collecting 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 conventional 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, cold, conditioned air is distributed through the house by reversing the heating process. Heat is not extracted, instead it is propelled 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 process as well.
