Installers should be Certified and Experienced
Because of the technical knowledge and equipment needed to properly install the piping, a geothermal system installation is not a do-it-yourself project. To find a qualified installer in your area, contact the S.A.G.E Group, or click here to Locate a Dealer.
Even though the installation price of a geothermal system is usually more than an air-source system of the same heating and cooling capacity, the additional costs are returned to you in energy savings. System life is estimated at 24 years for the inside components and 50+ years for the ground loop.
The ground heat exchanger in a geothermal system is made up of a closed or open loop pipe system. Most common is the closed loop, in which high density polyethylene pipe is buried horizontally at 4-6 feet deep or vertically at 100 to 400 feet deep. These pipes are filled with an environmentally friendly antifreeze/water solution that acts as a heat exchanger. In the winter, the fluid in the pipes extracts heat from the earth and carries it into the building. In the summer, the system reverses and takes heat from the building and deposits it to the cooler ground.
The air delivery ductwork distributes the heated or cooled air through the house's duct work, just like conventional systems. The box that contains the indoor coil and fan is sometimes called the air handler because it moves house air through the heat pump for heating or cooling. The air handler contains a large blower and a filter just like conventional air conditioners.
