Hi BluePlanet.
I'm guessing the service guy turned off the anti-cycling feature; Vaillant Anti-Cycling Mode Explained - Compare The Boiler Market - https://comparetheboilermarket.co.uk/vaillant-anti-cycling-mode possibly as part of the service and checks.
Why this might cause additional noise...
Silly Q - you do now have a large basin and/or towels sitting under the boiler?
That is bizarre, and obviously worrying. As you say, there's few 'system-water' components above that dividing shelf, other than the MainX and the two pipes supplying it. Any longer-term leaks from the pipe...
Fab, thanks Chris - phew, a sensible move by a manufacturer (and obviously more likely to stick with the make). Cool - he's going for a Pro 28, so slightly more powerful.
Thanks, Shaun.
From what I understand, the old boiler has been moved, but not yet recommissioned (part of a larger kitchen refit). Advice is to have it replaced as it's old, hence looking for an 'exact' swap if possible.
Is the plus 831 still made? Or, will the pro 28/30 fit easily?
Hi.
Looking to replace a 13-year old 824 with a new combi as its location is being moved, so seem like a good time to also replace. The new boiler needs to be more powerful - 30kW (as against 24kW?) - as the mains supply will also be upgraded.
The old 824 has actually had its pipes shifted to...
I see what you say, but that would be true of any system with TRVs, Smart or not.
I just mean that individual Smart TRVs, on at least the rads that are used on a daily basis - should provide the ultimate control, and therefore saving. Bedrooms will be the most obvious application - have these...
Ha-ha! I have to say, I think that Smart TRVs are great :)
Ok, I only have one - in the main bedroom - as t'kids have flown t'nest, but it means I don't need to run up and down t'stairs morn and eve turning the rad manually on and off. And I certainly have no intention of leaving the bedroom...
Hi.
Mil's UFH has Wavin 230V 2W actuators - model 1026. One went 'pop', and I've ordered a replacement, but the fellow that turned up is their newer model, the 35CS498, a one-watt jobbie in a straighter-sided body.
I've asked the seller - the Underfloor Heating Store - if they are fully...
