Types of Water Cylinders

Unvented Hot Water Cylinder – The systems pressure is from the cold mains water supply, which then flows through as hot water at mains pressure, this will enhance the performance of your bath and shower. Cold water storage tanks are not needed for unvented cylinders, which works in your favour if you have space issues.

An immersion heater can heat up the water, as can the central heating system or other renewal energy. If you are wondering if multiple fuel sources would be good to use, you should consider a thermal store.


Vented Hot Water Cylinder – A cold-water tank is required for a vented hot water cylinder and they are normally kept in the loft space of a property. To allow the trapped air to escape you must use the cold-water tank. This will also perform as an expansion tank to supply the expansion of hot water.

A vented cylinder is slightly different from an unvented cylinder as it does not require any extra expansion vessels.

Electrical Hot Water Cylinder – An efficient way of heating water is with an electric immersion, which captures the loss of energy which can be passed through pipework, and circulating pumps.

Indirect Hot Water Cylinder –Indirect cylinders do not heat the water directly. An external source provides the water to get heated inside the cylinder. The gas boilers water is heated up, which then flows through a coil that goes through the indirect cylinder, which then heats the water.

Megaflo Cylinder – An unvented system, which is a stainless-steel cylinder, is part of the central heating system the cylinder stores hot water. A megaflo cylinder can help improve the water pressure around the home.

The direct water cylinder heats the water up directly it has an element inside of them, which is typically 3KW.
