What is the maintenance and upkeep of a geothermal system?
There are two parts to your Geothermal system the inside portion and the outside portion. The inside portion consist of the heatpump and its associated parts you could compare it to your current boiler. The inside is covered by a conditional warranty for ten years. The outside portion consist of your bore holes, and loop field these currently are covered by a 50 year manufacturer’s warranty. If you think you may live beyond 100 you should know that there are currently closed systems that have been functional for 200 years in the U.S. To make sure your system is running efficiently, change your filter on a yearly basis.
