How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climatic zones that means hot summers that cool to ice-cold winters, and Utah is no exception. What many people don't realize 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 absorbs 47% of the sun's energy (heat) as it hits the Earth's surface. WaterFurnace geothermal systems are able to extract 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 Using the earth loop, a WaterFurnace geothermal heat pump pulls the heat from the ground in the heating cycle. The geothermal system draws the heat from the loops and passes this warmed air through a traditional 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, refreshing air is circulated throughout the house by reversing the heating process. Heat is not pulled, instead it is pushed 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 technique as well.
