Unvented Hot Water Cylinders

What are Unvented Hot Water Cylinders?

Vaillant supply unvented hot water cylinders for use in many homes around the UK. Unvented cylinders operate directly from the mains water supply, providing a high pressure flow of water and can use an immersion heater to suplement the heating of the water. An unvented cylinder has built in safety measures to help support the high water pressures.

Advantages of an Unvented Cylinder

The advantage of an unvented cylinder is that no additional tanks are required. Hot water can be provided constantly by the cylinder at mains pressure. Also, an unvented cylinder can be positioned in any suitable location as no other forces such as gravity are affecting the flow of water. The fact that an immersion heater is used to heat the water means that there is less reliance on the boiler.
