Hi Scoobydo I am interested to know what "GC" stands for, and who they are and function etc? Have you any more details? The reason I ask is because I asked the Gas Safe Register about a problem of safety of absence of setting up instructions from guess who - Vaillant - for an auto by-pass...

Thank you +++ for this news. It is interesting they seem to have been aware of the problem, while at the same time not quite denying it! I note your update is installed. Was it a question of getting a new VRC 430. (mine is the ebus version, not radio VRC 430f.) How did you procure it? Who...

I do not have the wireless 430F which I think you have, but I installed the VRC430 (hard-wired eBUS) last autumn. I have been impressed by it as a functional programming unit. I like being able to step quickly and easily through various "zones" and functions and adjusting a whole week's...

I actually DO NOT work on GAS things, and wouldn't nowadays. Although I have for years, nowadays I reckon a court would come down in favour of a piece of paper, though we have much evidence of how inaccurate their allocation sometimes is! Analysis first, modesty second - sorry about that...

I agree with that wholeheartedly. It is also the law. smokebox

I'll quietly accept I am an unregistered RGI man, I will not accept I am speaking BS! Tell me which other BS is worrying you. I am thanking the guys who have maintained an intelligent, timely and helpful approach. I don't know for sure who is and who is not RGI. but I have the fortune to...

gass wizard Read the previous few contrbutions, to put it in context. Remember we are not all gas registered men, and some of us are interested in learnibg about boilers etc - not neccessarily gas safe fixing type work. A broad mind can be a wiser mind. smokebox

Matt Makes sense smokebox. I have learned so much on this thread. Thanks to all you expert contributors! Agile was actually quite right. I started like a know all pri*k. but soon began to be humbled quite a bit! I beleive with your collective help, especially Hailsham, Agile...

Matt Isn't it actually closer to 1220/60 per sec = about 20 litres/sec = about 4 gallons per sec! smokebox seems excesscive but with Agile's further information maybe not!!

Agile a fascinating glimpse of a 'burn' occurring - thanks smokebox

Agile As always your field experience is invigorating! Thanks. Your solution to revert to auobypass, while using Auto-mode Alpha2, however gets me right back to page 1!. Illogical, out of line with Grundfos's pdf s that MJN uploaded for me, and in ordinary running, loosing condensing function...

Matt Together with Agile's point above, and yours now, I am being forced to regroup my thoughts rather drastically, and concede there is more to this cooling down after flame extinction than I realized!!!! I think your unloading (at high volume flow) into a standing zone is the best heat...

Agile I had no idea! That is fascinating, and somewhat salutory, to say the least! Thank you vary very much for this info. smokebox

But matt this huge throughput of 1220 litres/ min (20.3 litres/hr) can never be maintained in all situations. It is because of the wrong (impossible) statement in the Vaillant manual, and their refusal to acknowledge this that whole thread was raised by me, as you have spotted. In a way the...

Yes onetap - I reckon it his highly likely Vaillant has an anticipatory computed algorithm for impendind change in heat demand. They maw well be a bit secretive about this id detail! smokebox

Barry camb I agree about burying in the wall seems very counterintuitive for an air readingg thermomometer and stat. There will be hopeless lags in time response and relevance of timely information. I note the instructions are pretty clear about surface mounting! smokebox

Moderator can you help me! I hit ignore for Barrycamb in error when i wanted to quote him! and reply. Can you restore him for me please! ASAP Smokebox

Gary I am very interested in Vaillant's way of advising your heating curve of 2.3. ? did it sound like a 'reasonable' guesstimate, or a bit more scientific, or just a sensible starting point? What information did they request about he house? smokebox

Matt Yes you have, and very many thanks! I am planning to follow that route when a bit better, I hope smokebox
