The next generation in unvented cylinders from Advanced Water Company

Water storage has come a long way since Edwin Rudd created the first hot water cylinder in the 19th Century. By the 1980’s, when Fabdec manufactured the first domestic unvented hot water cylinder, every development before and since has been designed to overcome a problem: 

How do we heat the water most effectively, from what heating source, how do we make the water suitable for drinking and how do we get better pressure to the taps? What happens when there is too much water pressure, when the temperature gets too high and how do we stop too much/little water flow? These questions have led to the range of valves and vessels that we now see forming standard parts of a hot water system and make our pressurised units safe to use.

One of the more interesting developments in recent times has been the development of internal expansion air gap. This new type of cylinder has no need for a separate expansion vessel which in turn meant less parts to install and less space required. This product has become the cylinder of choice for many installers, housing providers, merchants and so on. And rightly so, the technology is excellent but there are some questions:

What happens if the air gap loses expansion capacity? 

The system needs to be re-pressured. 

How often does it lose pressure? 

The cylinder should be recharged once per year but if the water pressure is high, systems can lose pressure more regularly. 

Does the system need to be drained to re-pressure? 

Yes (costing time and money).

The latest generation of Hot Water Cylinder has been engineered by Fabdec to overcome these problems. By using 3S technology (patented by Fabdec), the Excelsior-i unvented cylinder self-regulates its internal expansion capability and feeds the air-gap through a Venturi device fitted to the cold water feed.

Advanced Water Company have partnered with Fabdec to bring this exciting new product to the UK market. Call on 01386 760066, email [email protected] or visit the AWC website for more information.
