How Geothermal Works We all know that Charleston homes are acceptable to varying temperatures during the year. Some climates can see the extremities that summer and winter throw at us. There is a dependable source of temperature that you can utilize; just a few feet under the earth's surface. How is that possible? The sun imparts the Earth's crust with its heat energy. Forty-seven percent of that energy is cumulated in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; harvesting this free heat for your home. This innovative technology uses the sun's heat that the earth has readily accumulated to condition your home or office. Geothermal Heating Utilizing the earth loop, a WaterFurnace geothermal heat pump takes the heat from the ground in the heating cycle. The geothermal system sucks 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 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 dispersing 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 Charleston area, contact Custom Climate Heating & Air.
