Do Geothermal Systems Require Frequent Repair?
There can be some concern in regard to repairing geothermal systems because of how the system is set up. As such, one of the main concerns is how frequently do geothermal systems need repair? The answer is: very infrequently. Not only are geothermal systems made to be durable, their operation is very different from more traditional systems, so the risk of malfunction is far less. Understanding how geothermal systems work helps explain why geothermal systems do not have the same frequency of breakdowns as other systems, so let’s take a look at how a geothermal system works. Geothermal Operation A geothermal system takes advantage of the steady temperature of the ground below the frost line to heat your home. It does this via a ground loop filled with a solution (typically anti-freeze) that absorbs the latent heat and transfers this heat to the ground-source heat pump. The heat pump concentrates the heat, then distributes it to your living spaces. What About Repairs? The ground loop is a simple component that does not have mechanical parts; in fact, the main mechanical component in a geothermal system is the heat pump. Furnaces and boilers are mechanical devices with moving parts, which makes them more prone to developing problems; a geothermal system does not have multiple moving parts. Additionally, unlike traditional combustion heating systems, geothermal systems do not generate heat; instead, they transfer heat. This, too, helps the system to be more stable. None of the geothermal components are exposed to the outdoors, which helps protect the parts from corrosion and damage. Lastly, the average lifespan of the equipment is some of the longest around: ground loops have an average lifespan of 25-50 years and the heat pumps have an average lifespan of 20-25 years. Geothermal systems are the most energy efficient heating and cooling system available, so don’t let the possibility of geothermal repair in Lino Lakes keep you from considering a geothermal system for your home.
