Unvented Cylinders

An unvented hot water cylinder is an excellent upgrade for homes that need a reliable, high-pressure hot water supply without the need for a separate cold water tank in the loft. Unlike traditional vented systems that rely on gravity and a header tank, an unvented cylinder connects directly to the mains water supply, providing good hot water pressure throughout your home.

McGhie’s Plumbing and Heating supplies and installs unvented cylinders for homeowners looking to improve the performance of their hot water system.

The Advantages of an Unvented Hot Water System

The most immediately noticeable benefit of an unvented cylinder is water pressure. Showers perform better, baths fill faster and hot water can be supplied to multiple outlets at the same time, subject to the incoming mains supply. Because the system connects directly to the mains, there is no need for a cold water storage tank, freeing up valuable space in your loft or airing cupboard.

Unvented cylinders are available in a wide range of sizes, making them particularly suitable for homes with higher hot water demand. When correctly sized and installed, they provide a reliable supply of stored hot water for bathrooms, showers and other outlets around the home.

Replacement and Upgrade Options

If you already have an unvented cylinder that is ageing, underperforming or developing faults, our team can assess whether a repair is viable or whether replacement would better suit your needs.

Replacement may also be worthwhile if you need greater hot water capacity, are adding bathrooms or showers, or are making wider changes to your heating and hot water system. We’ll give you straightforward advice on your options and a clear quote before any work begins.
