How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climatic zones that means blazing summers that cool to ice-cold winters, and Central is no exception. What most 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 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 used to provide your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump employs the earth loop system to draw the heat from the ground. With delivery through a classic duct system, the geothermal system draws heat from the loops and distributes it as warm air. Options are available to use that same heat energy to provide hot water heating and radiant floor heat. Geothermal Cooling During the cooling mode, cool, conditioned air is circulated through the house by reversing the heating process. Heat is not pulled, instead it is propelled into the ground. The warm heat is extracted from your home and moved back into the earth loop. Your hot water heating can be fueled by this process as well.
