Powerful hot water without the loft tank
Prime Plumbing & Heating is built on doing the job properly: honest advice, tidy workmanship and systems that perform reliably long after installation. An unvented hot water cylinder stores heated water under pressure and delivers strong flow when you open a hot tap or run multiple outlets—ideal for busy households.
Because unvented cylinders are fed directly from the mains, they don’t require a cold-water storage tank in the loft, helping save space and often improving consistency compared to older vented systems. We’ll assess your property and usage, recommend the right cylinder size and specification, and install it safely with the correct controls and safety devices.

We had a really old boiler system that needed replacement. We used the Worcester Bosch ( WB) fast track service to have a local WB accredited engineer come out and do a survey and provide a quote. We were lucky enough to be allocated Prime Plumbing and Heating and Ricky came out to look things over. He spent about 20-30 minutes reviewing our boiler and advising us on our options. He really knows what he’s talking about and is so professional and also a really nice chap, we felt in capable hands and so it proved. The team he sent out to do the work were all excellent, they worked so hard over 3 days and were all highly skilled and very courteous and professional. Their work was very clean and tidy. In our experience Prime Plumbing and Heating provided a service that exceeded our expectations. Thank you so much to the whole team.Posted on A STrustindex verifies that the original source of the review is Google. Excellent work and customer service.
