How Geothermal Works As the seasons move from spring to winter, temperature varies throughout the year. Some climates can range from scorching summers to frigid winters; Oswego 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 retained in the ground a few feet below the surface. WaterFurnace geothermal systems tap into this free heat with an earth loop. This inventive technology salvages the sun's heat providing your home or office with central heating and cooling. Geothermal Heating During the heating cycle, a WaterFurnace geothermal heat pump uses the earth loop to extract heat from the ground. As the system draws heat from the loop it circulates it through a traditional duct system as warm air. The same heat energy can also be utilized for a radiant floor system or domestic hot water heating. 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 removing 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 Oswego area, contact Nodines Heating Inc..
