Stainless Lite Direct An unvented cylinder for use with electric

It is available in 8 different sizes ranging from 90 litres to 400 litres, with the 400 litre model capable of satisfying the hot water demands of a property with 3 bathrooms and 2 separate shower rooms.

The direct model comes complete with two immersions, one for on-peak use and one for off-peak use. Therefore the store of water can be heated utilising the off-peak electricity, making the unit extremely efficient.

All models have a temperature and pressure relief valve which is factory set at 6 bar and 95 degrees celsius.

(Please note the 90 litre model is only supplied with one immersion and the 400 litre model is supplied with two immersions for off-peak use.)

All Gledhill Hot Water cylinders from the stainless steel range are made from the very latest high specification grade of Duplex stainless steel, to resist all forms of corrosion, including crevice and stress, whilst its high mechanical strength gives it fantastic durability. The very latest automated welding procedures along with full post weld treatments guarantee welds that are as strong as the parent metal. Stainless Lite unvented is pressure tested in the factory to a full 12 bar which is four times the normal working pressure.

heat exchanger to give a 20% faster recovery

Gledhill unvented cylinders were the first to use a high heat transfer corrugated tube heat exchanger to give a 20% faster recovery than plain tube.

Maximising the hot water potential

The unique Gledhill diffuser used in the unvented range of stainless steel cylinders reduces turbulence when cold water enters the store by baffling the flow. The end result is that the hot water output is equal to the capacity of the cylinder. A 250 litre unvented vessel will produce 250 litres of hot water. Check out the competition as some hot water cylinders are significantly better than others. The practical benefit is that the space taken up by the cylinder is all dedicated to hot water storage and so a smaller cylinder can be chosen compared with other manufacturers products.

Heat loss

All Gledhill stainless steel cylinders incorporate the very latest HCFC-free EnviroFoam insulation. This has an Ozone Depletion Potential (ODP) of zero and an industry leading Global Warming Potential (GWP) of 0.7. Tests show that the EnviroFoam insulation injected into the case and covering both domes achieves astonishingly low levels of heat loss, which ensures it is fully compliant with 2010 Part L requirements for both new build and replacement cylinders.
