Zilmet - 12 Litre Heating Expansion Vessel & Sealed System Kit Z1-301012

Fitted several of these they’re a good make. If you’re going to buy one I would recommend getting one from Amazon. They appear to be the cheapest around plus you get the accessories with it

Bought this to swap in for the exact same model of expansion vessel which had lasted 15 years but finally suffered a bladder failure. The swap was straight forward and the fixing bracket on this was identical to the in-place fixing bracket so no significant fiddling about was required to mount the new expansion vessel. It was pre-charged to 1.5bar, which was confirmed during fitting. Painless job to fit, and hopefully good for another decade and a half.

Great product and great value

Expansion vessels and control valves seem to be one of those plumbing items that eventually leak. This kit was a direct Zilmet replacement and arrived the next day for a good price. My only caveat is that over the years the patterns change slightly, so don't assume it fits without some effort.

This was bought by our parts department as it was the best price in the field

Fantastic kit for the price

Perfect
