Unvented Cylinders

An unvented cylinder is a pressurised hot water storage system that connects directly to the mains water supply, delivering strong and consistent hot water pressure to every outlet in your home without the need for a cold water tank in the loft. For households where hot water demand is high or where existing water pressure has been a frustration, an unvented cylinder can make a significant and immediate difference.

At RWR Plumbing Limited, we are qualified to install, service and carry out repairs on unvented cylinders, offering a complete and professional service for homeowners looking to upgrade their hot water system.

The Advantages of an Unvented Hot Water System

One of the most commonly cited benefits of an unvented cylinder is the improvement in water pressure. Because the system is fed directly from the mains, you get powerful, consistent pressure at every tap and shower in the house, regardless of how many outlets are in use at the same time. This makes unvented cylinders particularly well suited to larger homes and households where several people need hot water at similar times. In addition, because there is no requirement for a cold water storage tank, you gain back valuable loft space. Unvented cylinders are also well insulated, retaining heat effectively and helping to keep running costs in check. Modern units are compact, efficient and designed to integrate neatly into a range of property types.

Installation by Qualified Engineers

Unvented cylinders must be installed by engineers who hold the appropriate G3 qualification. This is a legal requirement in the UK, reflecting the fact that pressurised hot water systems need to be fitted and commissioned correctly to operate safely.

Our team holds the necessary qualifications and experience to carry out unvented cylinder installations to the highest standard, ensuring every system is properly set up, tested and compliant with current regulations. We take the time to select the right cylinder size and specification for your home and to ensure the installation is completed to a finish you will be satisfied with.



Servicing and Ongoing Maintenance

Like any pressurised system, an unvented cylinder requires regular servicing to remain safe and efficient. Annual maintenance checks should be carried out by a qualified engineer and include inspecting the pressure relief valve, expansion vessel, thermostat and other critical components. Keeping up with regular servicing protects the long-term performance of the cylinder, reduces the risk of unexpected failures and ensures the system continues to meet current safety standards. We offer unvented cylinder servicing as a standalone appointment, and we are also happy to combine it with a boiler service visit for added convenience.
