How Geothermal Works The temperature throughout the year will always vary no matter what climate you live in. For some climatic zones that means blazing summers that cool to frigid winters, and Rochester is no exception. What many people don't understand is that the temperature below ground (regardless of climate or season) stays pretty consistent year round. 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 hits 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 extract the heat from the ground. With delivery through a traditional duct system, the geothermal system draws heat from the loops and distributes it as warm air. Other choices 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 doing the exact opposite as the heating process. Heat is not pulled, instead it is propelled into the ground. The warm heat is pulled from your home and taken back into the earth loop. Your hot water heating can be fueled by this procedure as well.
