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 frigid winters, and New Haven County 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 retain a higher rate of constant temperature because it takes in 47% of the sun's energy (heat) as it hits the Earth's surface. WaterFurnace geothermal systems are able to extract this free energy with an earth loop. This technology is then used 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 choices include using that same heat to provide hot water and radiant floor heating are available. 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 taken 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.
