How do water heater elements work?
A water heating element is a pair of upper and lower heating elements that fit into a water heater of some sort. An electric current is passed through the elements which then heats the cold water to the selected required temperature. The temperature is set externally on the thermostat.

What causes water heater elements to burn out?
Below are some causes:

• Power surge - a sudden voltage increase to the element caused by a power surge can be enough to burn out an element.


• Wires - a bad connection can cause an element to stop working.


• Thermostat tripping out- these have a high limit switch that shuts off power to the elements when temperatures exceed normal.


• Minerals - sediment collects at the bottom of the water heater tank, encasing the lower element. Forced to work harder, the element eventually fails.


• Air pockets - these allow the upper element to burn while not immersed in water, resulting in failure.

Note

Although these elements are designed for use in water, it is possible to use these elements in a variety of solutions, however it is recommended that you consult the manufacturer prior to specification.
When installed the lower heated part must be completely immersed.
