How Geothermal Works The temperature throughout the year will always vary no matter what climate you live in. For some climates that means blazing summers that cool to ice-cold winters, and Denver 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 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 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 passes this warmed air through a classic 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, cool, conditioned air is distributed throughout the house by doing the exact opposite as the heating process. Heat is not extracted, instead it is pushed into the ground. The warm heat is pulled from your home and transferred back into the earth loop. Your hot water heating can be fueled by this process as well. For more information on how to get started with a geothermal system in the Denver area, contact WaterFurnace .
