How Geothermal Works As the seasons change from spring to winter, temperature fluctuates throughout the year. Some climates can range from fiery summers to freezing winters; Defiance included. Did you know there is a pretty constant temperature, regardless of climate or season, just below the ground? The Earth's crust absorbs 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 salvages 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 circulates 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 household hot water heating. Geothermal Cooling During the cooling mode, cold, conditioned air is circulated through the house by reversing the heating process. Heat is not extracted, instead it is propelled into the ground. The warm heat is pulled from your home and transferred back into the earth loop. Your hot water heating can be fueled by this technique as well.
