Replacement expansion vessel placement
Hi, need to replace a failed boiler expansion vessel* how critical is it
to place an additional (replacement) expansion vessel close to the boiler? From what I read it seems the concensus is as close to the boiler as possible or Bad Things will happen, but I've also seen installations where a system boiler has an expansion vessel in a remote cupboard. So it can't be all that bad? *Vaillant, so no surprise there, but it did manage to last a few years. I really don't want to demount the boiler to replace the internal one and space around the boiler is very limited, hence the question. |

I can't see why it would need to be close to the boiler. |

Most modernish Vaillant boilers have a very easy to get at expansion vessel - typically on the right hand side of the case.

Has worked fine for the last ten years. I would say that its not that critical. ;-) Tim -- Please don't feed the trolls |

Install a cutoff valve anyway, thus ensuring that the expansion vessel will never fail because now you can swap it out with ease? Thomas Prufer I've seen plumbing jobs where it looks like someone was working with Es. NT |

Vis (silver thing top right): http://wiki.diyfaq.org.uk/index.php/...cotec824HE.png It would be nice, but there isn't enough clearance above the boiler to remove the Expansion vessel in situ - at least according to Vaillant anyway. This one has the flat red vessel at the back, the one in the link does look easier to change. |

Well that's that settled then :)
It's going in a convenient space in a storage cupboard - about 4m from the boiler. The CH pipes already run through said cupboard so should be straightforawrd... |

Thomas Prufer Given the poor service life reported for two of the brands I looked at, this might not be a bad idea! :) |

Put it low down & it can "air" the cupboard, a bit (like the good old days, a bit) :-) -- Jim K ----Android NewsGroup Reader---- http://usenet.sinaapp.com/ |
