How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climatic zones that means blazing summers that cool to freezing winters, and Abilene 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 retain a higher rate of constant temperature because it absorbs 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 utilized to provide your home or office with central heating and cooling. Geothermal Heating Using 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 choices include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling Conditioning air is just the reverse process used in the heating cycle. Warm air is pushed by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air dispersing throughout your home. Heating your water during this process is "free".
