How Geothermal Works We all know that Atlanta homes are acceptable to varying temperatures throughout the year. Some climates can see the extremes that summer and winter hit us with. There is a consistent source of temperature that you can utilize; just a few feet beneath 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 stored in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; gathering this free heat for your home. This state-of-the-art technology uses the sun's heat that the earth has readily deposited to condition your home or office. Geothermal Heating During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it circulates it through a standard duct system as warm air. The same heat energy can also be utilized for a radiant floor system or domestic hot water heating. Geothermal Cooling Conditioning air is just the reverse process used in the heating cycle. Warm air is pushed by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air radiating throughout your home. There is no cost to heating your water during this process.
