Heat Pump Cylinders


Whitewolf Cylinders is a 3rd generation hot water cylinder manufacturer, and the largest white-label cylinder manufacturer in the UK. Our heritage in the industry dates back to the establishment of Copperform in 1967, revitalising Range Cylinders in the 1990s/2000s, and growing RM Cylinders into a sector market leader in the 2010s.


Our team combines strong engineering expertise with unmatched market experience. Our talented workforce and state-of-the-art manufacturing base means we respond to any order request, large or small, with smooth efficiency and short lead times.


We let the quality of our products speak for themselves, and strive for superior quality at a fairer price.


Our aim is to provide outstanding OEM products to distributors, manufacturers, and other companies in the plumbing and heating sector, while building enduring industry partnerships that will last a lifetime.




We're extremely proud of the quality of our unvented cylinders, and offer a 25 year warranty on the vessel as standard (terms and water hardness conditions are listed in the installation manual).

This warranty is honoured via the Benchmark log at the back of the installation manual that accompanies every cylinder. The commissioning checklist must be filled out by a competent and qualified installer upon installation of the cylinder, and is required to be updated with every annual service. The installation manual therefore acts as the guarantee for every homeowner, and must be kept with the cylinder. 

There is no mandatory warranty registration required online to validate your cylinder, however an optional jotform is provided on the right-hand button below, should you feel happier doing so. However, this does not replace the use of the physical log book.

If you have any questions about the warranty of your unvented cylinder, please feel free to contact us below.
