Slimline Unvented Hot Water Cylinders

If you are looking to squeeze your cylinder into a tight space, we also offer copper Slimline Unvented Hot Water Cylinders.

Typically measuring, an industry leading, 450mm in diameter including the insulation, 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 flexible approach to manufacturing and our use of copper, we can manufacture our hot water cylinders as small as 300mm diameter shell size, plus the required foam lagging.

We can even place the connections in the best location for the installation, making further savings on installation time and costs.
