How Geothermal Works We all know that Port Washington 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 utilize; just a few feet under the earth's surface. How is that possible? The sun permeates the Earth's crust with its heat energy. Forty-seven percent of that energy is stored in the ground as heat. WaterFurnace geothermal systems tap this heating potential using an earth loop system; gathering this free heat for your home. This cutting-edge technology uses the sun's heat that the earth has readily accumulated to condition your home or office. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump employs the earth loop system to extract the heat from the ground. With delivery through a conventional duct system, the geothermal system pulls heat from the loops and distributes it as warm air. Options are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling Conditioning air is just the reverse process used in the heating cycle. Warm air is driven by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air dispersing throughout your home. Heating your water during this process is "free". For more information on how to get started with a geothermal system in the Port Washington area, contact Professional Geothermal Systems.
