How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to ice-cold winters, and Oswego is no exception. What most people don't realize is that the temperature below ground (regardless of climate or season) stays fairly consistent all year. The ground is able to maintain a higher rate of temperature consistency because it absorbs 47% of the sun's energy (heat) as it hits the Earth's surface. WaterFurnace geothermal systems are able to tap into this free energy with an earth loop. This technology is then put to use to equip your home or office with central heating and cooling. Geothermal Heating Utilizing the earth loop, a WaterFurnace geothermal heat pump takes the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and passes this warmed air through a traditional 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 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..
