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 frigid winters, and Boise is no exception. What many people don't understand is that the temperature underground (regardless of climate or season) stays pretty consistent year round. The ground is able to sustain a higher rate of temperature consistency because it takes in 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 put to use to provide your home or office with central heating and cooling. Geothermal Heating Using the earth loop, a WaterFurnace geothermal heat pump takes 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 Conditioning air is just the reverse process used in the heating cycle. Warm air is driven by the geothermal heat pump into the ground. By getting rid of the warm air, all that is left is cool air circulating throughout your home. There is no cost to heating your water during this process.
