Do you Struggle with Frequent Element Replacements and Excessive Scale Build-up?
Then XTEND Elements are the solution
Lower operating temperatures (240°C) than resistive elements (500°C) which reduces precipitation of solids out of the water
PTC elements have a very low watt density which aids in reducing scale build-up
316 grade stainless steel casing provides long term protection from scale build-up to the ceramic element

Do you Struggle with Frequent Element Replacements and Excessive Scale Build-up?
Then XTEND Elements are the solution
Ideal for Hard Water
lower operating temperatures (220°C) than resistive elements (500°C), which reduces the precipitation of solids out of the water
PTC elements have a very low watt density, which aids in reducing scale build-up
316-grade stainless steel casing provides long term protection from scale build-up to the ceramic element
XTEND elements use a ceramic core and protect this with stainless steel to provide a long-lasting element that provides an affordable solution for hard water areas. The lower operating temperature also means there is less limescale build-up. While there are water filtration systems and water softeners, these are often prohibitively expensive. There are also hard water elements and titanium elements available, though they are heavy on electricity and do still corrode in very hard water conditions.


XTEND elements prevent this from happening by protecting the element with a large straight stainless-steel tube. Any scale build-up is located in the middle around the heating core, however, and most importantly, this scale build-up will not affect the performance of the ceramic element inside. Heat is simply transferred around the scale build-up.
It is also possible to service your XTEND element to clear away excessive scale build-up if you live in an area where elements do not last long at all.

Over Time Hard Water Damages Standard Elements
This can all be caused by limescale build up from heating "hard water" and corroded by a high metal count at certain temperatures. As the limescale builds up the element has to work harder to achieve the same result, costing more to run, and will eventually burnout if the scale build up is excessive.

Case Study with XTEND Elements in Hard Water Area
Problem statement: In hard water areas, the limescale build-up is responsible for many element replacements. Limescale build-up also reduces efficiency by up to 50%. This results in high running and replacement costs. Elements are generally replaced every 2-3 months, if not sooner.
Location: South 32 Mine, Mpumulanga
Water Quality: Hard
Proposal: Install an XTEND element

2 months after installation
XTEND element still working and client enjoying savings. XTEND was removed to check limescale build-up and re-inserted as this was not significant.

12 months - before cleaning
XTEND element still working and client enjoying savings. XTEND was removed to check limescale build-up, which had increased.

12 months after cleaning with CalC Clean
XTEND element looks as good as new and was re-inserted and is still working and saving the client money.
