Worcester 25si expansion vessel removal and replacement

[wuzdirt]

Hi all,

Ive got a job on to replace the expansion vessel on a 25si Worcester. Customer has test the valve and water is present.

Without seeing that particular boiler model in a while can anyone recall if the thing can be removed without removing the flu that he said runs directly over and out the back (over the vessel).

I cant recall without seeing the boiler whether its possible to get it out without all the hassle (I know some models have different mounts to aid this).

Otherwise might leave it in situ and fit another close by.

Help greatly appreciated.

The 25si & early Greenstar are both at the rear, can be done if you have enough height above boiler and you can get flue out of the way
