The ground remains at a constant temperature year round about six feet below the earth’s surface. In the winter months the ground is warmer than the surface and in the summer it is cooler. Using a series of liquid-filled pipes buried in the earth outside your home, a geothermal system gathers the heat from the earth and distributes it throughout your home when it’s cold outside. In the summer months, the system moves the heat from your home to the earth to cool it.
A geothermal system consists of a compressor, heat exchanger, geothermal unit and pipes. The system and the labor necessary to excavate and install the loops of pipe will cost significantly more than a conventional furnace. However, a highly-efficient geothermal system will save you so much in utility bills, that it’s possible to recoup your start-up costs in as little as 3 to 5 years.
If you have a well and strong pump for your domestic water supply, you may be able to hook your heat pump directly to your well. This eliminates the need to install a ground loop.
