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 freezing winters, and Mountain Home is no exception. What many people don't realize is that the temperature underground (regardless of climate or season) stays pretty consistent year round. The ground is able to maintain 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 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 delivers 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 Cooling the 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". For more information on how to get started with a geothermal system in the Mountain Home area, contact Custom Heating & Cooling Inc..
