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 equip your home or office with central heating and cooling. Geothermal Heating Utilizing the earth loop, a WaterFurnace geothermal heat pump extracts the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and distributes this warmed air through a standard duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. 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.
