Hot water cylinders come in two specific types: unvented and vented. Cylinders ensure that a generous amount of hot water is stored for ready, on-demand use, whether a domestic or commercial property.
Our engineers all carry G3 qualifications and a range of parts, so will be able to investigate faults and repair where possible.
These cylinders primarily differ in how they are supplied with water. Vented cylinders are gravity-fed from a cistern tank kept in the loft, whilst typically, the hot water cylinder itself will be fitted in an airing cupboard.
As the cold water is heated, it will expand – but the vent pipe and the tank in the loft act as overflow areas to which excess water can escape in the process.
An unvented cylinder will be connected directly to the mains, saving you from needing a cold water tank in the loft. This will provide your system with mains pressure water.
When water heats and expands in an unvented system, the excess water can move into an expansion unit or an air bubble fitted as part of the original installation.
This very much depends on the design of your property and, if applicable, on the current installation. We also need to take account of the incoming cold water flow rate and pressure. We will happily conduct a free and detailed home and family survey to advise you on the optimal system for you and your property.
Please contact us if you are experiencing problems with an existing vented or unvented system. If you are looking for a new installation, we can also arrange a home and family survey, whereby we will analyse the suitability of your property for a given system.
