Hot Water Dur-alloy Elements
What is Dur-alloy?
Using a specially processed High Grade stainless alloy, the Dur-alloy elements approach incaloy corrosion resistance for roughly the same price as copper.
Dissolved minerals (such as salt, calcium & lime) in the water supply can result in scale (like that found in a well used kettle which sometimes comes losse and ends up in your coffee) building up on a water heating element. Where these concentrations are high, this will considerably shorten the life of the element. Traditionally, elements utilising expensive stainless steel alloys such as incaloy (800 & 825) that are resistant to this scale build are used to extend element life in hard water areas but these are becoming less popular due to their higher prices.
