Geothermal is Green
Would you like to have a heating and cooling system in your home or business that can:
- Save energy
- Slash utility bills
- Drastically reduce hot water costs
- Cut greenhouse gas emissions
- Rid your yard of unsightly equipment and
- Reduce annual maintenance costs
…all while providing you year round comfort?
Then Go Green. Go Geothermal.
Geothermal systems are a cost effective, energy efficient and environmentally friendly way of heating and cooling buildings. Both the Department of Energy (DOE) and the Environmental Protection Agency (EPA) have endorsed the technology. Geothermal systems deliver reliable quality air-conditioning and heating, on demand, in every season.
How Do Geothermal Systems Work?
Geothermal systems are electrically powered systems that tap the stored energy of the greatest solar collector in existence: the Earth. These systems use the earth’s relatively constant temperature to provide heating, cooling, and hot water for homes and commercial buildings.
While many parts of the country experience seasonal temperature extremes – from scorching heat in the summer to sub-zero cold in the winter – a few feet below the earth’s surface the ground remains at a relatively constant temperature. Depending on latitude, ground temperatures range from 45°F (7°C) to 75°F (21°C). Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. A geothermal heat pump takes advantage of this by exchanging heat with the earth through a ground heat exchanger.
As with any heat pump, geothermal and water-source heat pumps are able to heat, cool, and, if so equipped, supply the house with hot water. Some models of geothermal systems are available with two-speed compressors and variable fans for more comfort and energy savings. Relative to air-source heat pumps, they are quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air.
Geothermal equipment is also compact and, except for the loop piping buried in the ground, is located inside, tucked neatly in basement, attic, closet, or crawl space.
