Indoor Comfort, Down to Earth Savings with Geothermal Heating A source of consistent, metered flow of conditioned air is already being tapped by many homeowners all across , WI, 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 geothermal system is dependent on the most abundant source of renewable energy and a source that is available virtually anywhere in the , WI, area. The result is a system that achieves green status in more ways than one: homeowners can lessen both their carbon footprint and their utility bills. In fact, the geothermal energy savings provided by a WaterFurnace geothermal system can be as much as 70 percent compared with a conventional system (natural gas, oil, electricity, or propane fuel). Additionally, the system removes noise pollution, with a sound level resembling a refrigerator. A 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, providing warm comfort. Inside the home, the heat is distributed through either a conventional duct system or a hydronic radiant heat system. Levels of indoor air pollutants are 2-5 times greater than those outside, according to EPA tests. A geothermal system confronts this concern as research shows that exposure to poor indoor air quality (IAQ) can lead to a variety of health problems such as, asthma, dizziness, fatigue and respiratory diseases. A variety of devices can be used to diminish 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 geothermal system and contribute to good IAQ throughout the home.
