Hot water is an essential part of everyday life and to have a precise temperature control and delivery on demand can be crucial. Immersion heaters are electric heating elements that are found in water cylinders to heat water. These elements perform like a kettle to heat the surrounding water in the cylinder. One key advantage of an immersion heater element within your heating system is that if the boiler fails, you should still be able to get hot water. The element usually has its own power supply which means that it can be turned on and off when needed so that water is not constantly being heated unnecessarily.

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.



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.
