Q: Hi, what is the working life of 9 kw element on a hard water tank fed system. On approximately 20 hrs a day .
— Asked by Stephen McMurray on October 27, 2020
A: The working life can vary significantly for immersion heaters, as it is very difficult to anticipate the working conditions of the unit. There are too many factors which would need to be taken into consideration when judging this. We’d suggest to choose a titanium immersion heater as this is a harder wearing sheath material compared to Incoloy or stainless steel, and is more resistant to corrosion from hard water. We’d also recommend to use a water softener. Another factor to consider is watts density. If you are able to use a 9kw element across a longer immersed length (such as 24 or 36”), this would reduce the watts density which would increase the longevity of the immersion heater.
