Indoor Comfort, Down to Earth Savings with Knoxville Geothermal Heating A source of consistent, metered flow of conditioned air is already being tapped by many homeowners all across Knoxville, TN, area. Geothermal heating and cooling is provided by the constant temperature found in their own backyards; just a few feet under the surface of the earth. The advantages of using this "down to earth" method for heating, cooling and hot water are many. One benefit, according to studies by the Environmental Protection Agency (EPA), of geothermal heating and cooling is that it's the most energy-efficient option available. The experts at WaterFurnace International, Inc., the leading manufacturer of geothermal heating and cooling products, add that a Knoxville geothermal system is reliant on the most abundant source of renewable energy and a source that is available virtually anywhere in the Knoxville, TN, area. A WaterFurnace geothermal system can achieve as much as 70% energy savings when compared to conventional systems like natural gas, electric or gas fuelled. The system removes noise pollution as well; operating at a sound level along the same lines a refrigerator would make. The result is a heating and cooling system that surpasses the efficiency of conventional systems while reducing your carbon footprint and your utility bills at the same time. A Knoxville geothermal system captures the free energy from the earth by using a series of pipes, called an earth loop, buried in the ground. During the heating mode, a special fluid flows through the pipe where heat energy is transferred from the ground (the heat source) to the fluid and then to the geothermal unit located in the home, supplying warm comfort. Inside the home, the heat is distributed through either a conventional duct system or a hydronic radiant heat system. A Knoxville geothermal system also addresses pollutants in the air. According to EPA tests, levels of pollutants are 2-5 times higher indoors than outside. Research also shows that exposure to poor indoor air quality (IAQ) can cause health problems including, asthma, dizziness, fatigue and respiratory diseases, among many others. A variety of devices can be used to decrease the health risks associated with poor IAQ and improve the air in your home. The WaterFurnace product offering includes HEPA filter technology, heat recovery ventilators, electronic air cleaners and a selection of filters, all designed to work with a Knoxville geothermal system and contribute to good IAQ throughout the home.
