Product Information

When it arrived it had all the labels as on the already fitted [[ASIN:B01BGZQVY6 ARB18 Expansion Vessel (Baxi Megaflow system) ]].

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.

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. When water is heated it expands and as water is not compressible this increased volume will create a rise in pressure within the system. 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.To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Definitely recommed the seller and of course the ARB18 Expansion Vessel (Baxi Megaflow system) if you are looking for one.

THE AQUASYSTEMS ARB POTABLE EXPANSION VESSELS ARE MANUFACTURED TO COMPLY WITH UK WATER REGULATIONS AND ARE TESTED AND CERTIFIED BY WRAS.

All Aquasystem expansion vessels are supplied with a replaceable membrane, which separates the water and air, to prevent contamination of the water system, corrosion of the expansion vessel or pressure loss in the water system. An unvented cylinder is expected to be checked/serviced every year and that would usually include checking the EXV. Happy to get it done by G3 engineer but an idea of how long it will take so I can gauge cost would be a great help, as if I point it out to Valliant service guy Im sure the cost will be astronomical and they'd yellow tape the system and switch it off if I didnt proceed. The installer of the system was in last year to pump up the vessel and said it was unlikely to last much longer, however looking at Gas Safe the installers of that firm now have no unvented certs so hesitant to get them back in.

I am sure that you check and top up your car tyres every few weeks so why do you not expect your EXV not to be checked for three years at a time. As the process is going on, the membrane deflates until the pressure reaches its minimal threshold value. 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.

At this point the membrane is back to its initial dimensions, the pump starts again and a new cycle begins.

Reliance Valves Aquasystem Replacement Vessel Membranes are available from 2 to 5000 litre capacity, which allows the vessel to be serviced in situ and prevents any water contact with the steel shell to prevent internal corrosion.
