Hot Water Cylinder Services

We install, repair and service vented and unvented hot water cylinder systems

Hot Water Cylinder Services

There are essentially two types of hot water cylinders that we need to be aware of: vented and unvented. Each of these cylinders supplies hot water to the property, however, they both do this in very different ways and the ways in which they do this determines the choice you make for your home. 

Vented cylinders store and heat water that is fed directly from a tank in the loft. As the tank in the loft is situated in a location higher than the vented cylinder, this provides a natural gravitational force of water to the system, enabling it to provide a flow of hot water to the tap outlets throughout the property. An unvented hot water cylinder differs in that it provides mains pressure hot water directly from the cold mains as opposed to tank pressure water provided with a vented cylinder. The cold water is directly pulled from the main water supply and is then heated by the selected heat source relevant to the cylinder type. One of the core benefits to point out with an unvented cylinder is the flexibility it provides when there are space restrictions in the property, as there is no requirement for a cistern tank. This means that the cylinder itself can be installed in the loft – out of sight and out of mind. 

We can supply, install, repair and service hot water cylinders. Please contact us for a free quote.
