INSTALLATION INSTRUCTIONS PDF: Telford Cylinder Installation Guide

The Telford Tempest is the flagship stainless steel unvented cylinder. Over the years there have been changes in the hot water industry that have caused manufacturers to offer lower grade stainless steel to remain competitive.

All Telford stainless products have remained the same high grade of stainless steel, up to 40% thicker than some products on the market today.

For Telford a family run company, quality is the first priority. Whilst remaining competitive, we offer a manufacturer’s lifetime guarantee, this gives both us and you the customer, peace of mind.
