How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can range from sweltering summers to cold winters; Beckley included. Did you know there is a fairly 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 maintained in the ground a few feet beneath the surface. WaterFurnace geothermal systems draw from this free heat source with an earth loop. This inventive technology salvages 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 extract the heat from the ground. With delivery through a standard duct system, the geothermal system pulls 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 all through the home. Instead of pulling 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.
