Where used with solar it is important to match the dedicated solar volume with the property specification to achieve

compliance with building regulations.

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.


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.


The 25 year guarantee underlines

the usual Gledhill confidence in its own products.
