Blue Diamond Heating Element
Heating elements start to scale over time, reducing efficiency
Heating elements used in water heaters are made of steel, so they will corrode and scale over time. Scales are the white particles which form on the surface of a steel heating element, reducing its efficiency.
Blue Diamond glass lined elements are coated with a protective layer which greatly reduces scales.
Blue Diamond elements maintain higher heating efficiency
Coating a Blue Diamond heating element is much more difficult than coating a Blue Diamond tank as the surface area of an element is more complex.
Over the years, A. O. Smith has mastered this skill. Now, Blue Diamond elements can effectively reduce scaling by 50%, maintaining high heating efficiency
The process of Blue Diamond coating is highly guarded
When glass-coating heating elements, one requires not only the perfect formula of glass, but the process of coating the element is also patented.
It is no surprise that A. O. Smith goes to a great extent to keep this part of their production line confidential.
