How Geothermal Works We all know that homes are subjected to varying temperatures throughout the year. Some climates can see the extremes that summer and winter throw at us. There is a dependable source of temperature that you can put to good use; just a few feet below the earth's surface. How is that possible? The sun infuses the Earth's crust with its heat energy. Forty-seven percent of that energy is stockpiled in the ground as heat. WaterFurnace geothermal systems tap this heating potential using an earth loop system; collecting this free heat for your home. This state-of-the-art technology uses the sun's heat that the earth has readily stored to condition your home or office. 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 delivers this warmed air through a classic duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. 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 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.
