Engineered for Efficiency

It's better by tube

The corrugated tube, inside the cylinder, increases the heating surface and creates turbulence which gives a 20% better heat exchange than plain tube.

The extra thickness of foam provides a cylinder with extremely low standing losses.

A new design of cold-water inlet diffuser has been developed which improves the hot water performance. The end result is that the hot water output is equal to the capacity. A 180 litre vessel will produce 180 litres of hot water!

Suitable for all boiler types

Joseph C Kenny Plumbing & Heating will advise you on the best cylinder to fit for your home, whether you are replacing an old cylinder or require a system for your new build or refurbishment. The cylinders can be fitted with oil, gas or electric boilers or solar panels.

Both vented and unvented cylinders with direct or indirect fittings are available. The only difference between the vented and unvented range of stainless steel cylinders is that instead of being supplied with the unvented kit, the vented option is supplied with a control thermostat and a drain valve.
