Benefits of Geothermal Heat Pumps
Geothermal Heat Pumps are the most environmentally friendly way to cool and heat your home. Combined with a low operating cost and short payback period, you'll be on your way to a greater level of comfort and efficiency in your home.
· Save up to 70% on your heating and cooling utility bills
· Geothermal Heat Pumps can pay for themselves in 5-7 years.
· More evenly distributed heating and cooling than conventional systems.
· Reliable ground loop systems have a life expectancy of 50+ yrs.
· Do your part to reduce green house gas emission and U.S. foreign oil dependency.
Ground source heat pumps rely on an energy exchange between the air within the building being heated and the ground. Below ten feet the earth's temperature is fairly constant, generally around ~10 °C (~50 °F). During the summer when the ambient temperature of the building exceeds that of the ground heat pumps are used to pump heat from the building in to the transfer medium (typically water with small amounts of ethanol or glycol) and is subsequently pumped through narrow pipes into the ground so that the heat can be dissipated in the earth. When the ambient temperature falls below the ground temperature the process works in reverse. Heat pumps extract heat from the ground and use it to heat the building.
Geothermal energy is a type of renewable energy that encourages conservation of natural resources. According to the U.S. Environmental Protection Agency, geo-exchange systems save homeowners 30-70 percent in heating costs, and 20-50 percent in cooling costs, compared to conventional systems.
