How Geothermal Works As the seasons change from spring to winter, temperature varies throughout the year. Some climates can vary from scorching summers to ice-cold winters; Idaho Falls included. Did you know there is a fairly 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 underneath the surface. WaterFurnace geothermal systems draw from this free heat with an earth loop. This inventive technology salvages the sun's heat supplying your home or office with central heating and cooling. Geothermal Heating Using the earth loop, a WaterFurnace geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and passes this warmed air through a conventional duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling During the cooling mode, cool, 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 pulled from your home and taken back into the earth loop. Your hot water heating can be fueled by this process as well.
