Why Titanium Heater Elements?


Calcified Element in Tube

Poor water chemistry is damaging to hot tub heater elements, particularly when amplified by abuse or neglect. Additionally, fill water that is naturally high in salt, lime and calcium can also promote slower, but premature death to elements. Below you will learn why titanium provides a superior defense against “adverse” water conditions, and will extend your hot tubs heater elements useful life.

Chemical failure/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.

Titanium is the Solution!

Titanium has become the solution to hot tub 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 hot tub heater longevity like titanium.

Titanium doesn’t allow scale to harbor onto the surface. Titanium naturally produces a dioxide film that continually migrate to the surface, and detaches harmful content. Additionally, titanium’s surfaces 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 most adverse 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 Hot Tub Heater Elements provide your best defense against common recreational water chemicals, and becomes more beneficial and a much better value, when water chemistry is less than perfect!

    I installed our 550 gal hot tub some 20 years ago in a deck adding each componet seperately. It has a Comfort Zone heater with two 8 inch folded 5500 watt elements and now leaks at the threads of the elements due to corrosion beyond the gaskets ability. I see you have a tube type heater. Could I replace the Comfort Zone (Haward)with the a tube heater? Would I possibly need to gang two in line? I’m a hands on person and can do the plumbing and wiring if you can sell me the parts and help with the tech help I might need.

      Hi Frank,
      Normally you need a spa control system to control an inline heater. We do sell self-contained heaters similar to what you currently have if you would like to look at those. Not being at your location and seeing what your set up is it is very difficult to provide technical advice, but we can gladly help you with your spa parts needs. Please let us know if you have any other questions.
