How Geothermal Works We all know that Northern Colorado homes are acceptable to varying temperatures during the year. Some climates can see the extremities that summer and winter hit us with. There is a consistent source of temperature that you can put to good use; just a few feet underneath the earth's surface. How is that possible? The sun imparts the Earth's crust with its heat energy. Forty-seven percent of that energy is stockpiled in the ground as heat. WaterFurnace geothermal systems extract this heating potential using an earth loop system; harvesting this free heat for your home. This cutting-edge technology uses the sun's heat that the earth has conveniently stored to condition your home or office. 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 standard duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling In the cooling mode, the heating process is reversed - creating cold, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
