Unvented Cylinder Installation

Do you have a cold water tank in your loft that seems more trouble than it’s worth?
Have you had your cold water tank freeze over long winter periods? Do you find you are often having shortages of hot water? Then an unvented cylinder might be a great option for you.
 
Since its introduction to UK homes in 1986, the unvented hot water cylinder has seen a huge rise in popularity. An unvented cylinder is fed directly by cold water mains, meaning that, unlike the bulky old cold water tank in your loft, it does not rely on gravity to work, and can be placed almost anywhere in your home.
People with unvented cylinders also find that there is less noise in their system, as there is no filling up of a water storage cistern.
At Highfield Plumbing and Heating, we draw upon our wide professional experience to understand the quirks of your home and your hot water needs.

Tempest Stainless - Hot water installation in Mansfield
Unvented Cylinder Installation Mansfield

Bespoke Unvented Cylinder Installation in Mansfield

Not every hot water upgrade is straightforward, and this Mansfield installation was a perfect example of why experience matters.

The customer needed a new hot water cylinder, but the available space was extremely tight. A standard off-the-shelf cylinder simply would not fit safely or correctly.

Rather than forcing a compromise, our team arranged for a bespoke cylinder to be manufactured specifically for the property, ensuring the perfect fit without sacrificing performance, safety or reliability.

Before work began, we fully protected the customer’s home, covering flooring, surfaces and walkways to keep disruption to an absolute minimum.

Once the old cylinder was safely removed, we adapted the existing pipework and carefully installed the custom-made Tempest stainless steel cylinder, making sure all safety controls, pressure settings and connections were completed correctly.

The result was a perfectly fitted hot water system, reliable performance, and another happy customer.

Need help with a difficult hot water cylinder installation in Mansfield, Chesterfield or Nottingham? Highfield Plumbing & Heating is here to help.

Unvented Cylinder FAQs

Common questions about unvented cylinders, servicing and bespoke hot water cylinder installations.

An unvented hot water cylinder stores hot water under mains pressure. This means you can enjoy strong hot water flow without needing a cold water tank in the loft.

No, that is one of the main benefits. An unvented cylinder is fed directly from the mains water supply, so it removes the need for a traditional cold water storage tank.

We recommend having your unvented cylinder checked once a year. This helps make sure the safety controls, valves and general system are working correctly.

Yes, we can inspect leaking or faulty unvented cylinders and advise on the safest repair option. In some cases, replacement may be recommended if the cylinder is old or badly damaged.

Yes, unvented cylinders are often paired with system boilers. This can be a good setup for homes that need reliable heating and plenty of stored hot water.

Yes. If space is limited, we can assess the area and arrange a suitable cylinder option for the property. In some cases, this may mean using a bespoke cylinder designed to fit the available space safely.

Most cylinder installations are completed within a day, but this depends on the property, pipework, access and whether the cylinder is a standard or bespoke fit.
