For a short time only, we are offering a fantastic £20 off all Gledhill Unvented Cylinders.

Unvented cylinders are the ideal solution for homes that require substantial amounts of hot water. They ensure a large amount of stored hot water is available on demand for domestic requirements. Unvented cylinders connect directly to the mains water system to provide high water flow rates, consequently creating higher water pressure for household appliances.

Unvented cylinders benefit from not requiring a feeder tank in the loft as they are directly fed from the mains water supply. Therefore, these particular cylinders are ideal for smaller properties where space is at a premium. Unlike vented cylinders, unvented variations do not depend on gravity to function, meaning they offer far more flexibility for installation location.

As unvented cylinders are sealed systems, they require an expansion vessel to allow for the volume increase of cold to hot water.

Manufactured from high quality stainless steel, Gledhill Unvented Cylinders are designed with durability in mind.

All Unvented Gledhill Cylinders are included in this offer – but hurry, this deal is only available until 1st December!
