Expansion Vessel Siting

[Riley]

Not strictly a gas issue here but need some advice in conjunction with an old Worcester 24i combi. Exp vessel has failed and will not hold a charge. Intend to fit an external vessel however the only accessible pipework is a pipe with an AAV on it in what was the old airing cupboard. Now I know the ideal situation for an external vessel is on the return near to the boiler but it’s just not feasible due to space can anyone envisage an issue with teeing into this pipe in the airing cupboard. As surely expansion is expansion?

Why not replace the boiler vessel? Doddle on that boiler.

 

[Riley]

Have I listed the wrong boiler?? It’s the old school with the vessel on the back

 

[Chalked]

Bracket on the top and pull out the hose from the block.
Vessel slips out.

 

[Riley]

Doesn’t come past flue and not enough clearance above boiler even if flue removed

Are you running another PRV also? Or just the external vessel? I know that this is a massive cost but will they not considere a new boiler if it is the old 24i? I wouldn’t want the responsibility myself of fitting the vessel that far from the boiler.

 

[Riley]

No I know what you mean but he is dead against replacement

 

[Riley]

To be fair this would be directly above boiler slightly offset maybe a meter and and a half

If I had to

To be fair this would be directly above boiler slightly offset maybe a meter and and a half

could you run another PRV from the vessel if it is that close?

 

[Riley]

I could do a prv but would this be overkill? The one on the boiler is fairly new as the last engineer just replaced that

Maybe. Just trying to get to a place where I would be happy.

Thanks mate I appreciate your help it’s just one of these where the LL is trying to penny pinch and I’m only doing it as a favour to the letting agent as they put loads my way

Why not just lift the boiler off the jig? Disconnect flue elbow, drain the boiler and then just undo 5 nuts? Looking at max 1.5hrs work. Fitting an external vessel will probably take as long. The expansion vessel will still work in the position you have stated though if you wanted to go that route.

Boiler off these days can be done under an hour but if it's your first time allow 2

Favour jobs always a pita, Letting agents always wanting something for nothing, try not to be reliant on work from them they will always try to pressure you in to doing "Favours"

 

[Riley]

Oh they seriously do put a lot of good regular work my way with no payment problems so I don’t mind helping out. It’s not my first time removing a boiler but have not had great experiences with doing this on older boilers so was trying to avoid this if at all possible. Thanks all for the thoughts
