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 freezing winters, and Scranton is no exception. What many people don't understand is that the temperature below ground (regardless of climate or season) stays fairly consistent all year. The ground is able to retain a higher rate of constant temperature because it absorbs 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 draw heat from the ground. As the system draws heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or household hot water heating. Geothermal Cooling The heating process is reversed in the cooling mode - creating cool, conditioned air all through the home. Instead of pulling heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
