Poor water chemistry is damaging to heater elements, particularly when amplified by abuse or neglect. Additionally, fill water that is naturally high in salt, lime and calcium can also promote a slower, but premature death. Below you will learn why titanium provides a superior defense against “adverse” water conditions, and will extend your elements useful life
Corrosion is the etching and rusting effect that happens to ferrous metals. As water becomes acidic (low in ph) or overly chlorinated, corrosion is accelerated and your heater element is most at risk. Titanium is not a coating and is non ferrous (less than .03% iron) and therefore will withstand greater chemical punishment, without the pitting, etching, or surface breakdown of typical nickel alloys.
Lime & calcium can naturally collect on the element’s surface, and form a white “scale” coating. This insulating layer will slow heat transfer, resulting in lower efficiency, longer run periods, and a higher internal temperature. This excess buildup will not let heat escape efficiently, and in time the element will cook itself to death.
Titanium is the Solution!
Titanium has become the solution to heater longevity, and has long been the best defense against chemical & mineral abuse. Even with today’s salt chlorinating systems, there has been no other material that has improved heater longevity like titanium.
Titanium doesn’t allow scale to harbor onto the surface. Titanium naturally produces a dioxide film that continually migrates to the surface, and detaches harmful content. Additionally, titanium’s surface pores do not open when heated, and will not allow harmful chemicals or particles to collect. This “self scaling” miracle can be verified in your own dishwasher. As heavily concentrated detergents are added weekly, your element remains nearly scale free for years. The best commercial and residential dishwashers are equipped with titanium elements for all these reasons.
Titanium contains no iron, & therefore cannot rust or corrode. Given the worst water conditions, titanium can resist pitting, oxidizing, and surface breakdown up to 10 times better than typical nickel alloy elements. Titanium is not magnetic, and will not attract materials that can attach and promote deterioration. Additionally, titanium has an exceptionally low thermal expansion rate, and this will reduce the stress that can cause structural fatigue and fracture.
Titanium provides your best defense against common recreational water chemicals, and becomes more beneficial and a much better value, when water chemistry is less than perfect!
