Should I Replace Hot-water Cylinder?

[Traveller 47]

I have a vented hot-water cylinder that was installed when the house was built - 38 years ago! It has a header tank in the loft and the cylinder is located directly above the ceiling of a new and expensive kitchen. It does not leak and causes no obvious problems. Should it be replaced?
Advice appreciated.

I wouldn't bother if there are no signs of trouble.

No, it is likely to be of better quality than a new one!!

Hi It looks fine to me, just wasting money to change it, if there was any issue with it you would see signs of water leakage and there is nothing obvious from the photos.
one question though we're does that 15 mm pipe go that is teed into the 22mm hot water feed at the top of the cylinder?

Thanks for the replies. The 15mm pipe teed off at the top of the cylinder feeds a shower unit on the other side of the house - works well.
