18 Litre Aquasystems ARB18 Potable Expansion Vessel 3 Bar with Integrated Bracket - XVES050055

Product Information

The installation was very simple, the engineer powered off the mains of the boiler and replaced the vessel and restarted the system and it was all good. The existing [[ASIN:B01BGZQVY6 ARB18 Expansion Vessel (Baxi Megaflow system) ]] was installed in 2003 and the registered engineer said the reason I have to keep topping up the system on a daily basis was due to the expansion vessel.

At this point the membrane is back to its initial dimensions, the pump starts again and a new cycle begins. The expansion vessel allows for this extra space, as when water temperature increases the membrane inside the vessel inflates to allow the water to fill the vessel. These replacement membranes are quick and easy to install and can be used with all Aquasystem replaceable membrane potable and heating expansion vessels. THE AQUASYSTEMS ARB POTABLE EXPANSION VESSELS ARE MANUFACTURED TO COMPLY WITH UK WATER REGULATIONS AND ARE TESTED AND CERTIFIED BY WRAS. Expansion tanks are also known as expansion vessels and are used to protect closed water heating systems and domestic hot water systems from excessive pressure.If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag.

Due to the pressure from the pressurised air surrounding the membrane, water will start to exit the vessel until the membrane is deflated.
