How Geothermal Works As the seasons change from spring to winter, temperature varies throughout the year. Some climates can vary from sweltering summers to cold winters; Greene County 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 sustained in the ground a few feet below the surface. WaterFurnace geothermal systems tap into this free heat source with an earth loop. This innovative technology recovers the sun's heat supplying your home or office with central heating and cooling. Geothermal Heating During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to draw heat from the ground. As the system draws heat from the loop it distributes it through a standard duct system as warm air. The same heat energy can also be used for a radiant floor system or household hot water heating. Geothermal Cooling During the cooling mode, cold, refreshing air is circulated through the house by reversing the heating process. Heat is not extracted, instead it is pushed 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 process as well.
