How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climatic zones that means hot summers that cool to ice-cold winters, and Omaha is no exception. What many 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 sustain a higher rate of temperature consistency because it takes in 47% of the sun's energy (heat) as it impacts the Earth's surface. WaterFurnace geothermal systems are able to draw from this free energy with an earth loop. This technology is then put to use to provide 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 pulls 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 household hot water heating. 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 radiating 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 Omaha area, contact Getzschman Heating & Air Conditioning.
