Apologies for the 'silence' in terms of longer term behaviour after the adjustment happened. Reason is that I changed the entire heating system after a couple of months, hence was not (and would not) be able to comment whether the slight mechanical adjustment of the thermocouple relative to...

WEll, based on lot of reading thought that the pressure indicated by the gauge is a reflection of the pressurised heating system. So if it indirectly heats the hot water with the same 'system water' that is quite indirect and low efficiency. Otherwise of course it would have to pump the actual...

thanks, one nagging thing is just that I assumed the pressure in the system it measures (the heating part) is really disconnected from hot water supply-related part. So if the CH pressure gauge fluctuates this much by just using hot water, there must be quite some heat transfer to the CH-related...

Hello, something that slowly and surely drives me crazy on the new CD35C combi boiler from Alpha- any thoughts highly appreciated, as this was observed for weeks and weeks now: 1. We start with pressure gauge showing 1 bar, in middle of green area on the display. 2. If the system had...

sounds excellent and doable even with my skills - indeed lots of measuring :) Many thanks.

Hi, recently had the old backboiler ripped out (had the boiler and a gas heater/radiator part) from the lounge. It left behind a 45 x 72 cm gap in the sandstone coloured rugged surface decorative brickwork that covers the lower part of lounge wall. The right edge is smooth, the left edge...

Hi, quick update - had the visit today and cleaned gas injector for pilot light, also the engineer said that he adjusted a bit the thermocouple position relative to the flame, as it was barely touching even on maximum setting for pilot light gas flow. So explanation was that it may have...

Thanks - last week when servicing was done, only measured the gas pressure at the boiler measurement point. So will suggest this, too - from visual assessment, can't see pilot light change in the short (5-10seconds) time period between burn ending and pilot clicking off, but this is something...

Quick update- probably by end of this week will be looked at. In the meantime, has to be re-started every time it finishes a burn - few more phone conversations concluded that it might be an 'adjustment' of the thermocouple relative to the flam in case it got moved during last servicing...

Sorry guys for getting back to this with some delay, my Saturday was chaos. Indeed, it's Glow Worm 45, in its manual and what I saw during last 3 servicing visits since '07 there was no sign of separate o/h stat, seems pretty 'dumb' - i.e. I only see now (from a frontal look) thermocouple...

yep there's a mighty vent near it, quite cold draft nowadays. I've been bringing in Southern Electric to clean and service it each year since I bought the place, this year switched to a checkatrade.com chap who lives nearbya and Gas Safe registered (S.E. said there 'may' be asbestos in chimney...

it does, thanks- it matches 9.4 in the manual I have. Also explanation makes sense, clearly I see therefore just part of the picture through the window. I might shelf :-) the thermocouple he brings next week (I can only hope... "will ring as soon as part is in") and then redirect him...

totally repeating myself: thanks heaps - again, really. Lightbulb indeed - good news is then next week he may not poke around for N visits and N thermostats + whatever :-) One thing that surprised me anyway was that watching the pilot right after the burner stops, couldn't see any change...

Something that either cracks you up or opposite effect: what does ASD stand for? :-( Is it what the manual calls lower sensing tube (and has a filter on it) ? if yes, will it then lead to such cut-off only after nice long burns? it doesn't seem to have a fit on its own for short burn...

Which then brings me back to initial theory: no overheat stat it seems, and the boiler stat only kills main burner as I hoped for (after all, it should allow the burn to continue bit later which needs pilot light) - therefore something, somehow decides to kill pilot, but in a...
