How Geothermal Works As the seasons move from spring to winter, temperature fluctuates throughout the year. Some climates can vary from scorching summers to freezing winters; Columbia included. Did you know there is a fairly consistent temperature, regardless of climate or season, just below the ground? The Earth's crust absorbs 47% of the sun's heat (energy) and is sustained in the ground a few feet under the surface. WaterFurnace geothermal systems extract this free resource with an earth loop. This inventive technology reclaims the sun's heat providing your home or office with central heating and cooling. Geothermal Heating Utilizing the earth loop, a WaterFurnace geothermal heat pump extracts the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and delivers this warmed air through a conventional duct system. Additional options 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 driven 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. 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 Columbia area, contact WaterFurnace.
