Unvented Cylinders
A high-pressure hot water system that allows you to run multiple showers, taps and appliances at the same time without a drop in performance. Unvented cylinders installed, replaced and serviced across Berkshire, Surrey and Hampshire.
High-Pressure Hot Water
Reliable hot water when you need it
Unvented cylinders deliver hot water at mains pressure, providing a stronger and more consistent flow throughout your home.
This means you can run multiple showers, fill baths and use taps at the same time without the water pressure dropping, making them ideal for modern households with higher demand.
Unlike traditional systems that rely on a cold water tank, unvented cylinders are fed directly from the mains supply. This removes the limitations of gravity-fed systems and allows hot water to be delivered more effectively across the entire property.
The result is a system that not only performs better but also supports everyday use without compromise.

Where It Works
Suitable for a range of homes
Unvented cylinders are well suited to homes where strong and consistent hot water performance is important.
They are particularly effective in properties with multiple bathrooms, larger households or where multiple outlets are likely to be used at the same time.
They can also be installed in place of older vented systems, providing a noticeable upgrade in both pressure and overall performance.
Performance
Strong water pressure and consistent flow
One of the main advantages of an unvented cylinder is the ability to maintain strong water pressure even when multiple outlets are in use.
In practical terms, this means you can run more than one shower at the same time, or use taps and appliances without the flow dropping or temperature fluctuating.
This level of performance is particularly important in homes with multiple bathrooms, where traditional systems often struggle to keep up with demand.
By delivering consistent pressure across the system, an unvented cylinder provides a more reliable and comfortable experience day to day.
