Oh dear, I spoke too soon when I noted that BigBurner had apparently been banned and resurfaced as Water Systems.
He posts as Dr Drivel and as Water Systems, yet another of his many "names".
Whats worse, he is still up and at it after midnight!
He hides his real identity, his profile is "private", he does not go to exhibitions, CIPHE meetings, ARGI meeetings or local curry evenings.

I would think he spouts enough hot air without warming it up.
Since Drivel is back, perhaps he could explain why the cylinder hasn't moved from it's present location for years, when the OP clearly states it was part of an extension, and gave the impression it was moved as by the builder as part of the work.
Clearly the cylinder is probably 15-20 years old and in a poor state.
You are also forgetting it was the expansion vessel that burst and not the cylinder which is much weaker.
You are also forgetting that expansion vessel are nearly as common as TVs in domestic houses.

That picture was a potential design nightmare!
The EXV was directly coupled to the hottest part of the cylinder and bound to run at 50-60°.
To subject a component with a rubber inner lining to high temperatures is to invite failure.
Baxi/Potty made a similar mistake with their "instant" boilers which ran the EXV at 80° and had them failing every 1-2 years.

So you assume. Nevertheless, a violent explosion occurred, and it was not because of the discharge pipe.
I don't think a violent explosion occurred, it just gave out through metal fatigue.
That's correct they didn't open, so rightly or wrongly we can assume the pressure was normal.
It is a simple task to get the expansion vessel tested, in fact I would suggest a must.
Well spotted Kevin.
The EV failed not because of poor manufacture, but lack of maintenance and of course the installation method (I'm being polite).
And have you noticed the most basic fault with the solar pipework from the cylinder too?.
