Unvented Cylinders

Unvented hot water cylinders are connected directly to the mains water supply, offering the benefit of better flow rates which in turn help baths and showers perform better; an appealing option for customers. With this in mind, Plumb Center’s range of unvented cylinders helps cater to the needs of any trade installation.

Since first becoming legal in the United Kingdom in 1986, unvented hot water cylinders have become enormously popular with homeowners. Unlike their vented counterparts, unvented hot water systems don’t need a cold water tank in the loft, freeing up valuable space and eliminating the risk of freezing during the cold winter months. Because they don’t rely on gravity, they can also be installed almost anywhere on a property – another attractive benefit for homeowners.

What’s more, as the system is essentially sealed, there’s little risk of contamination as the water moves from the cold water tank into the hot water system.

We offer a huge range of unvented hot water cylinders from trusted names in the plumbing industry, including Albion, Centerstore and Dimplex. Find everything you need to install a new heating system online from Plumb Center – all at competitive trade prices.
