Superior durability, reliability and efficiency.

Stainless steel vented cylinders are the perfect upgrade for a traditional copper cylinder, providing many superior benefits like improved durability, reliability and efficiency. Vented hot water storage cylinders are gravity-fed from a cold water cistern tank, usually located in the loftspace of a property.  The vertical distance determines the operating pressure and the cylinders have an open vent pipe from the top of the cylinder back to the cold water tank, to equalise any excess pressure within the system.

Our vented cylinders have no sacrificial anodes either, which are often used with inferior grades of stainless steel or copper to achieve corrosion resistance. The high quality marine grade duplex stainless steel performs in even the most aggressive hard water areas and conditions, providing a longer operational life and with no anode to inspect or replace, maintenance costs are significantly reduced.
