If you are considering a geothermal heating and cooling system for your home, a logical question would be: how long will the parts and equipment last? One of the often overlooked benefits of a geothermal heating and cooling system is the fact that it will outlast most conventional HVAC systems by a large margin.
Unlike an air source heat pump, a geothermal heat pump is placed within the home. Located in the basement or garage, the heat exchange equipment is protected from the outdoor elements. The harmful effects of cold, rain and debris are not a factor with indoor equipment. As a result, the heat pump life expectancy should be at least 20 years and is often much longer. And since noise is not a factor, locating the system indoors makes perfect sense.
In addition, the water circulating pipes, whether buried in the ground or submerged in a well, are extremely durable. Geothermal loop piping is most often made from high density polyethylene, which should last many decades under normal use. With a warranty of 50-years and a typical life expectancy of 200 years, geothermal piping should perform well for many generations.
Where a connection is needed, two pipes are heated and fused together. This creates a bond which is at least as strong as the piping itself. Under no circumstances are mechanical fittings used as these types of joints can eventually fail and leak.
A geothermal heating and cooling system will perform reliably and save money for many years to come.
