Sort this out & electrics & you could be the first pro in BG.
Just don't try it in GB!!

Where is this thread actually going? @ShaunCorbs ?

I know I can definitely do this. I've already done a lot of electrical work (for myself) there. I've had to. Nobody ever does it right.

Would never need to as there are good plumbers here (well.....the majority)

It's gone from expansion vessels, to unvented cylinders, to self appendix ops, now can we get back on topic?! We're discussing expansion vessels, not blood vessels!
Seriously though, I don't know how unvented cylinders came up in topic as it wasn't relevant.

You have an unvented cylinder eg mains pressure water cylinder

You have an unvented cylinder eg mains pressure water cylinder

With a fully working safety relief valve which was never an issue.

 

[johnduffell]

my hint would be before or after makes no difference on the expansion, but you need to make sure there are no valves whatsoever that could separate the water that's being heated from the expansion vessel plus pressure relief vessel:

That couldn't be more important.

I'd guess this is Bulgaria?
Unvented cylinder installations and incidents take no account of borders and need suitably qualified people to work on them.
If it doesn't have an expansion vessel it definitely needs one.

I am under the impression that our European cousins allow heated water from sealed systems to expand up the incoming cold main in lieu of an expansion vessel on unvented systems.

Problem is mate he’s asking on a uk forum so I don’t think we can advise
