Geothermal Information

Homeowners around the world have learned that a geothermal system is the smarter way to reduce your carbon footprint and utility bills at the same time. Geothermal systems use the free, renewable energy found in your own back yard to save on heating, cooling, and hot water costs. What are geothermal heat pump systems?

Geothermal or ground source heating and cooling is a high-comfort, cost-effective, and environmentally friendly technology that takes advantage of the Earth's capacity to store the Sun's energy in the form of heat. Geothermal heat pump systems store heat from your home in the earth during cooling and retrieve it from the earth to heat your home in the winter. A small amount of electricity is used to operate the pumps, fan, and compressor, which, along with the earth heat exchanger are the major components of the ground source heat pump system.

The earth heat exchanger consists of a piping system circulating a water or water /antifreeze mixture through the piping system from the heat pump to the earth. Because of the refrigeration circuit in the heat pump the ground temperature need not be especially warm and these ground loop systems will perform efficiently virtually everywhere in the U.S.

The value of investing in a geothermal system can be measured by calculating the energy cost savings compared to a conventional air source heat pump or fossil fuel system. The monthly energy cost savings, in most cases, will exceed the "cost" of investing in the new geothermal system creating a net positive monthly cash flow. Also, hvac equipment replacement costs comparing the "life-cycle" or how long the geothermal system will last compares favorably to traditional heating and cooling systems. The estimated life of a geothermal system is projected by the American Society of Heating, Refrigeration and Air Conditioning Engineers to be approximately 24 years. A traditional gas furnace life expectancy is 18 years, while air conditioners and air source heat pumps both have life expectancies of 16 years, with proper maintenance. The value added to a home or commercial building by a geothermal system is measurable and the extra cost recoupable to the building owner through energy savings. Further advantages include: "free" hot water, no outdoor condensing unit (noise, maintenance, or vandalism), and geothermal heat pumps are the most environmentally friendly heating and cooling systems available today according to the US EPA.
