What Gledhill Hot Water Cylinders Are Available?

Made from high specification duplex stainless steel, our STAINLESSLITE PLUS range is built to resist all potential corrosion including stress and crevice

It is strong and durable due to its high mechanical strength. Automated welding, post-weld pickling, passivating treatment, and automated welding ensure that every individual weld is as strong or stronger than the parent metal.

The StainlessLite Plus cylinders have been pressure tested to 12 bar – four-times their normal working pressure – and injected with 50mm of our HCFC-free EnviroFoam insulation. This will ensure that you are able to enjoy the highest levels of energy efficiency.

The STAINLESSLITE PLUS RANGE comes in direct and indirect options. It is also available in sizes from 60 litres to 400 litres. They are compatible with solar thermal technology, heat pumps or a hybrid system that uses both.

The openvented boilers are for use with header tanks and conventional boilers, these are the ones where you may find your header tank leaking in the loft or similar!
