If you are looking to squeeze your cylinder into a tight space, we also offer slimline versions of our Unvented Cylinders.

Typically measuring 450mm in diameter, these slimmer models are manufactured to the same standards and designs as our POWERflow units and come with the full 25 year guarantee.

However, thanks to our unique approach to manufacturing hot water cylinders and our use of copper, we can manufacture cylinders as small as 300mm shell plus the required foam lagging.
