How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to ice-cold winters, and Michigan is no exception. What many people don't realize is that the temperature underground (regardless of climate or season) stays fairly consistent all year. The ground is able to sustain a higher rate of constant temperature because it absorbs 47% of the sun's energy (heat) as it impacts the Earth's surface. WaterFurnace geothermal systems are able to extract this free energy with an earth loop. This technology is then utilized to equip your home or office with central heating and cooling. Geothermal Heating Using the earth loop, a WaterFurnace geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and distributes this warmed air through a conventional 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, cold, conditioned air is distributed through the house by doing the exact opposite as the heating process. Heat is not extracted, instead it is propelled into the ground. The warm heat is extracted from your home and taken back into the earth loop. Your hot water heating can be fueled by this process as well.
