How Geothermal Works As the seasons move from spring to winter, temperature fluctuates throughout the year. Some climates can vary from fiery summers to freezing winters; New Jersey included. Did you know there is a pretty consistent 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 draw from this free heat 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 pulls heat from the loop it distributes it through a traditional 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, cool, conditioned air is circulated through the house by doing the exact opposite as the heating process. Heat is not pulled, instead it is propelled into the ground. The warm heat is pulled from your home and moved back into the earth loop. Your hot water heating can be fueled by this process as well.
