How Geothermal Works The temperature throughout the year will always vary no matter what climate you live in. For some climates that means blazing summers that cool to frigid winters, and Dexter is no exception. What most 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 constant temperature 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 put to use to provide your home or office with central heating and cooling. Geothermal Heating In the heating cycle, a WaterFurnace geothermal heat pump utilizes the earth loop system to extract the heat from the ground. With delivery through a standard duct system, the geothermal system draws heat from the loops and circulates 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 throughout the house by reversing the heating process. Heat is not extracted, instead it is driven into the ground. The warm heat is extracted from your home and transferred back into the earth loop. Your hot water heating can be fueled by this procedure as well.
