An immersion heater is an electric water heater that sits inside a hot-water cylinder, it acts a bit like a kettle, using an electric resistance heater (which looks like a metal loop or coil) to heat the surrounding water.
Immersion heaters consist of a brass boss, element, thermostat pocket and thermostat, they can be made of copper, Incoloy or titanium and come in varying element lengths and boss thread sizes.
If the cylinder is situated in a hard water area, its recommended to use an immersion with an Incoloy or titanium element to prolong the life of the immersion, also if the tank is only heated via immersions and its being used in student accommodation or in a home its recommended to use a titanium immersion.
Immersion heaters are connected to their own power supply via a cable, they can be easily switched on and off via an external programmer, as there is no need to constantly heat the water in the unvented cylinder.
The immersions are usually a specific size or style to the cylinder they are fitted to, this differs between the different manufacturers.
Immersion heaters can either be used as a property's primary water heater, or as a backup water heater if the cylinder is being heated indirectly by a boiler.
The immersion heater itself sits inside a hot water cylinder and is powered by a strong electric current, it runs off the mains electric and the electric resistance heater heats the water inside the tank until it reaches the designated temperature.
When the temperature drops below a certain level, the immersion heater comes back on until it reaches the required heat level again.
