How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can vary from scorching summers to ice-cold winters; West Branch included. Did you know there is a fairly constant 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 maintained in the ground a few feet under the surface. WaterFurnace geothermal systems tap into this free heat source with an earth loop. This creative technology reclaims the sun's heat providing your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump utilizes 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 circulates 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 throughout 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 transferred back into the earth loop. Your hot water heating can be fueled by this procedure as well.
