How Geothermal Works As the seasons change from spring to winter, temperature varies throughout the year. Some climates can vary from scorching summers to chilly winters; Van Buren included. Did you know there is a pretty consistent temperature, regardless of climate or season, just below the ground? The Earth's crust takes in 47% of the sun's heat (energy) and is retained in the ground a few feet under the surface. WaterFurnace geothermal systems tap into this free heat with an earth loop. This inventive technology salvages the sun's heat supplying your home or office with central heating and cooling. 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 classic duct system, the geothermal system draws heat from the loops and distributes it as warm air. Options are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling In the cooling mode, the heating process is reversed - creating cool, conditioned air throughout the home. Instead of extracting heat from the ground, heat is taken from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
