18 Litre Aquasystems ARB18 Potable Expansion Vessel 3.5 Bar with Integrated Bracket - XVES050056

It comes pressurised to correct BAR and ready for fitting or to replace existing one. A company quoted me in excess of £700 to replace the existing. I bought this from Amazon for less than £50. Another plumber who came to service the Boiler, fitted it in less than 10 minutes and did not charge me extra

Good price, just a shame the old ‘aqua system’ expansion vessel fitted with the cylinder only lasted 3 years! Let’s hope this one is of a better quality and that the manufacturer has upped their game! No complaints about the service of the supplier, prompt as usual.

Very fast delivery, came fully pressurised and ready to fit.

Exactly what I needed. Good price, good service - what more can you expect?

Well packaged, simple to fit. Recommend draining system down & heating is turned off. Plus Turn off that water valve . All done in 20 minutes

Accurate description, well-packed, and prompt delivery, all at a good price.

Never had any issues with this supplier, highly recommend

Arrived quickly but with a dent in it
