Unvented Cylinders
An unvented hot water cylinder is one of the most effective upgrades you can make to your home’s hot water system. Unlike traditional vented cylinders that rely on a cold water tank in the loft to supply pressure, unvented cylinders are connected directly to the mains delivering high-pressure hot water to every tap, shower and bath in your home simultaneously. At Plumbwise, our qualified engineers carry out unvented cylinder fittings and replacements to a high standard, giving you a more capable and efficient hot water system built around the needs of your household.
How Unvented Cylinders Differ from Traditional Systems
A traditional vented hot water system relies on gravity to deliver water pressure, fed from a cold water storage tank typically located in the loft. The result is often inconsistent pressure particularly on upper floors or in properties where the tank is not positioned high enough and the need for a dedicated loft space to house the tank itself. Unvented cylinders remove both of these limitations entirely.
Because an unvented cylinder draws directly from the mains water supply, the pressure of the hot water it delivers matches the pressure of your cold water supply making it significantly more powerful and consistent throughout the property. This is particularly noticeable in showers, where the difference between a gravity-fed and a mains-pressure system can be dramatic. The cylinder itself can also be positioned almost anywhere in the property, freeing up loft space for other uses and simplifying the overall design of your hot water system.
The Practical Benefits for Your Home
The advantages of switching to an unvented cylinder extend beyond water pressure alone. Modern unvented cylinders are heavily insulated, retaining heat for extended periods and reducing the energy required to keep stored hot water at temperature. This contributes to lower running costs over time and means your hot water is ready when you need it without the boiler needing to fire up constantly.
For households with multiple bathrooms or high simultaneous hot water demand such as families with busy morning routines an unvented cylinder with the right capacity provides a reliable supply to multiple outlets at the same time without the pressure dropping noticeably. The absence of a cold water tank also reduces the number of components in the overall system, simplifying maintenance and removing one potential source of future problems.
