How Geothermal Works We all know that Northern Virginia homes are acceptable to varying temperatures during the year. Some climates can see the extremities that summer and winter hit us with. There is a dependable source of temperature that you can put to good use; just a few feet underneath 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 stockpiled in the ground as heat. WaterFurnace geothermal systems draw from this heating potential using an earth loop system; harvesting 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 During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to draw heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be put to use for a radiant floor system or domestic hot water heating. Geothermal Cooling During the cooling mode, cold, conditioned air is distributed through the house by doing the exact opposite as the heating process. Heat is not extracted, instead it is propelled into the ground. The warm heat is pulled from your home and moved back into the earth loop. Your hot water heating can be fueled by this technique as well. For more information on how to get started with a geothermal system in the Northern Virginia area, contact Renewable Energy Solutions.
