How Geothermal Works We all know that Seattle 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 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 instills the Earth's crust with its heat energy. Forty-seven percent of that energy is stockpiled 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 cutting-edge technology uses the sun's heat that the earth has conveniently accumulated 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 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 getting rid of the warm air, all that is left is cool air circulating 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 Seattle area, contact Vaughn Mechanical.
