How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can vary from fiery summers to chilly winters; Burlington included. Did you know there is a pretty constant temperature, regardless of climate or season, just below the ground? The Earth's crust absorbs 47% of the sun's heat (energy) and is maintained in the ground a few feet underneath the surface. WaterFurnace geothermal systems tap into this free heat source with an earth loop. This inventive technology salvages the sun's heat providing your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump utilizes the earth loop system to draw the heat from the ground. With delivery through a traditional duct system, the geothermal system pulls heat from the loops and distributes it as warm air. Other choices are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling Cooling the 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. There is no cost to heating your water during this process. For more information on how to get started with a geothermal system in the Burlington area, contact Crabbe Service.
