How Geothermal Works As the seasons change from spring to winter, temperature varies throughout the year. Some climates can range from scorching summers to freezing winters; Starkville included. Did you know there is a fairly 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 sustained in the ground a few feet underneath the surface. WaterFurnace geothermal systems tap into this free heat with an earth loop. This ingenious technology salvages the sun's heat providing your home or office with central heating and cooling. Geothermal Heating Utilizing 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 distributes 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 Cooling the air is just the reverse process used in the heating cycle. Warm air is pushed by the geothermal heat pump into the ground. By removing the warm air, all that is left is cool air circulating throughout your home. There is no cost to heating your water during this process. For more information on how to get started with a geothermal system in the Starkville area, contact Mid South Air Conditioning, Inc..
