How Geothermal Works As the seasons move from spring to winter, temperature fluctuates throughout the year. Some climates can vary from scorching summers to cold winters; Williamsport 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 sustained in the ground a few feet below the surface. WaterFurnace geothermal systems tap into this free heat source with an earth loop. This ingenious technology recovers the sun's heat supplying your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump employs the earth loop system to extract the heat from the ground. With delivery through a conventional 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 The heating process is reversed in the cooling mode - creating cold, conditioned air all through the home. Instead of extracting 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.
