Huge savings can be made on can be made on the most efficient cylinders availible today

The Gledhill name is synonymous with a family of water heating and storage products that lead the field in terms of innovation and quality. We are respected for our world-leading range of primary stores, but we have also produced unvented cylinders from the very beginning. Stainless Lite is an unvented mains pressure store in Duplex Stainless Steel that establishes new criteria for quality, performance and life

 

Providing powerful, mains-pressure performance, it incorporates high flow rate controls, ideal for multi-bathroom homes, where baths fill very quickly, and flexible sitting options.

There are Indirect and Direct patterns for gas/oil and electricity with 14 models in total, with litreages ranging from 90 to 300. There are also an additional 8 options available catering for those with, or intending on, Solar technology so your home can work efficiently and reliably.

The Stainless Lite is also simple and easy to transport and manuvre when empty making installation easier and hassle-free.

 

Duplex Stainless

The Stainless Lite uses the very latest high specification Duplex to resist all forms of corrosion including crevice and stress whilst its high mechanical strength gives it the strength for long life. It is particularly light and easy to handle on site.

Manufacture

The very latest automated welding procedures along with full post weld treatments guarantee welds that are as strong as the parent material. Stainless Lite is pressure tested in the factory to a full 12 bar which is four times the normal working pressure.

More Hot Water

Stainless Lite uses a high heat transfer corrugated tube heat exchanger to give 20% faster recovery than plain tube. It is also lighter and stronger than plain tube making the vessel the lightest and easiest to handle on site.

Controlled Stratification

The unique Gledhill diffuser reduces turbulence when cold water enters the store by baffling the flow

Minimal Heat Loss

Tests show that the 50mm of polyurethane foam injected into the case and covering both domes achieves astonishingly low levels of heat loss.

Guarantee

The 25 year guarantee underlines the usual Gledhill confidence in its own products.
