Electric Immersion heaters

Immersion heaters are also known as elements. They can go in both vented cylinders and unvented cylinders. They heat the hot water in these hot water storage tanks with electricity. In direct cylinders they are the only source to heat the hot water. In indirect cylinders they are used as a back up if the boiler is not working. For you to choose the correct size you need is based on the size of your cylinder. Some immersion heaters go in the top of the cylinder and some go to the side. You need to measure the length or width of the cylinder to ensure that the immersion heater and stat will fit. Make sure that it is the longest that it will possibly fit for optimum results.
