What is an immersion element?

An immersion heater is an electrically powered component that provides hot water to your property. 

It uses a heating element immersed in a hot water cylinder filled with water; once it reaches the temperature set on a thermostat, it automatically clicks off and remains hot for a few hours depending on the level of insulation around the cylinder and the temperature around the cylinder

How do immersion elements work?

A hot water cylinder full of water is on average heated within 1- 2 hours of the immersion element being switched on. Electrical power running through a metal coiled element converts the electrical energy to heat, similar to an element in an electric kettle.

Depending on the size of your hot water cylinder, you may have multiple immersion elements fitted to help with heating the hot water.

Can immersion elements be plugged into the wall?

No immersion elements should be wired into a wall fuse spur and adequately fused.

Can immersion heating elements be wired in using standard cables?

No. due to the environment they are in, they should be wired in using heat proof cables to minimise risk of burns and fires
