hi Corylus, some pics of my own system that i installed some years ago showing A.A.V. in correct position, if the pics are any use for an example of how it should be installed you are quite welcome to use them, i and i am sure all the guys here wish you well, cheers

Thank you robbo for the pics. I will certainly make use of them. And thanks everybody for the support. What would I do without you?

I'm a bit unhappy about my poor plumber in all this. I am certain he would have put it right had he been told. But I have to say, it's a bit of a worry that a safety device can be installed so that it can't work.

 Haven't heard from Caleffi yet, but this will help. I'm not sure how to get the pics transferred off this site, but I guess I can work it out.

Thanks guys

Oh great. Thanks. I tried dragging it and got a lovely wee thumbnail. This is much better.

This is a marvellous website. Congratulations to whoever is responsible. I haven't begun to explore all it has to offer - never mind how to manage the bits and pieces. So now I have another one. Thanks robbo  :-*

Hi guys. Help me think this out? Just tell me where it's wrong.

If this AAV ain't working and the HWC is at 85 and the pump gets switched off by the controller, the water in the manifold is trapped? So it boils? And the steam can't vent. And as I understand it the conversion rate for water to steam, volumewise is 1660? That's some pressure up there then I imagine. And it continues to heat. Superheated steam? Must be a very well made manifold huh? It's a pity it didn't blow - he might have paid some attention to that. Instead it seems to have forced the steam against all its natural inclinations back down into the tank with resultant ructions as it collected up top trying to get out the narrow header pipe?

So. If the vent is actually working and steam can escape, the temp in the manifold shouldn't get above 100? Is this your experience? What happens when the steam is all vented then? The manifold is empty? That must be interesting for the pump once it gets switched back on?

I see you are all having fun with your red cards. I wish I'd known there was such a thing . . . but I can see they are causing you aggro. You're not alone with this board and its antics you know. It seems to be widespread. If you knew the inside story of what goes on in the field of education - you wouldn't let your kids go to school. The people who make the decisions are not involved in the actual work, so their decisions tend to be utter nonsense (feckin' stupid as Badger might say). Same in hospitals these days. And as for being a soldier . . . well . . . you can forget about the bods up there in their safe offices having a clue what they are about.

hi Corylus, your situation can be explained but i don`t see the point. I have to say that from all of your correspondence the system has not been installed correctly and no amount of tweaking will fix it. It seems to me that rather than trying to sort it, it needs to be disconnected so as to be safe before it becomes a `BOMB` then the whole thing re-installed by someone who knows what they are doing, sorry to be so negative but you must be thinking  enough is enough by now. So get someone to disconnect it and re-install the original system then look for someone who knows what they are doing to give some good advice, cheers

Hi robbo - yes that's the plan exactly. But I'm trying to put together my case and I need to know if my thinking is correct.

Your good advice needs money what I ain't got. Hence the need to screw some out of the guy who put it in. But I dont want to start  something unless I can win. So I need to be right. I'm hoping to horrify the referee by explaining what this man has done by installing a safety vent that can't work. That sounds OK but it doesn't tell the story of what is happening up on that roof - which is pretty damn horrifying. And worse - what goes on in my airing cupboard if I let it - which is terrifying as well.

Corylus - pressure alters the boiling temp of water

under normal conditions the vented steam is replaced/made up by water

in your case tube manifold not venting so next place for it to go is path of least resistance - because you have open vent it allows excess pressure out of system - just in your case it has to overcome the volume and head of stored water before it can get there (to atmosphere)

hi Corylus, if the original installer will not fix it, you are entitled to have it fixed by another installer then send the account to the original installer, it`s really as simple as that, of course if he will not pay then you have a concrete case at the tribunal,cheers

Hmmmm robbo. I'll have to think about that. He DID offer to fix it - ages ago . His idea of fixing it was to put a valve in the header pipe to let me have hot water. When I declined to have a bomb in my kitchen he went into " Well then - I've done what I can - if you won't accept it - I can't help it." But things have moved on since then.

But thanks for that. I didn't know such a thing was possible. I didn't like the idea of having some innocent plumber being out of pocket while I tried to extract money I might never get out of this guy. I'm sure you get my drift!

integrated. Thanks for the corroboration. I have this picture in my head of a whole manifold of water being totally converted into steam and needing 1660 times more room than it has got. Obviously it doesn't do that otherwise the manifold would be kaput. It would be interesting to know at what point the pressure forces the steam down the flow pipe instead. Who knows. I'm not that keen on having it all in the HWC either!

But it is behaving itself very well at present. No danger of overheating. And other than the nuisance of having to mess about with the prv and the cold water lever, it is giving us more HW than it ever did before.

No news from Caleffi. I think I might ask too many awkward questions people don't have answers to . . . :D
