About Newark Cylinders

Three generations of solving hot water problems

Newark Cylinders has been manufacturing hot water cylinders since 1977. What started as a family business in Nottinghamshire remains one today: three generations later, still independently owned, still building every unit ourselves at our production workshop in Newark.

That continuity matters. The knowledge built over nearly 50 years of manufacturing stays in-house, and so does the accountability.

What we make, and who we make it for

Our range covers domestic unvented cylinders through to large-scale commercial calorifiers, thermal stores, buffer vessels, and marine calorifiers. We work with individual installers and specifiers who need a single solution built to an exact brief, and with trade and manufacturing partners who need the same cylinder produced consistently over time.

Both get the same standard of manufacturing. Neither gets pushed towards something that doesn’t quite fit.

How we work

From your initial enquiry through to design, fabrication, and despatch, everything is handled in-house. We combine precision machinery with hands-on fabrication in stainless steel and copper. This means we can respond to complex briefs, unusual dimensions, specific coil configurations, or tight deadlines without outsourcing or compromising on quality.

There is no fixed catalogue and no off-the-shelf compromise. If your project needs it, we can build it.

Why installers and specifiers trust us

Our technical team works directly with installers, specifiers, and architects throughout a project, not just at the point of order. That means support on complex specifications, help translating unusual briefs into a manufacturable solution, and direct access to the people making your cylinders that larger manufacturers don’t offer.

It’s that combination of genuine technical knowledge, manufacturing flexibility, and consistent delivery that has built our reputation across the trade for almost five decades.
