How Geothermal Works As the seasons change from spring to winter, temperature fluctuates throughout the year. Some climates can vary from scorching summers to chilly winters; Mitchell included. Did you know there is a pretty constant 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 maintained 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 reclaims 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 takes the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and delivers this warmed air through a classic duct system. Additional choices include using that same heat to provide hot water and radiant floor heating are available. 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.
