What is the estimated life of a Solar Hot Water System?
Inter Solar uses all Aluminum, Stainless Steel or Copper parts for the Solar Hot water systems manufactured by us, hence they usually last for about 15-20 years depends upon water quality. Some maintenance may required periodically to get maximum efficiency like electric back-up etc. may need replacement. We have some of our very first Solar Geysers (manufactured 15-18 years ago!) still functioning properly to the great satisfaction of our customers.
