Steatite/ceramic element 

Ceramic elements are used for indirect heating of liquids in electrical water heaters, boilers, oil pre-heaters and industrial baths.

For these applications, the ceramic element is mounted in a tube.

Ceramic heating elements are preferred when the exchange of elements without emptying the tube or container is required. The elements are also used in applications with demands for reduced lime or coke formation, and when increased wall thickness of the tube due to heavy pressure stresses is required.
