    Not going to be that easy sorry. As the UFH will never ask for more than 35oC, the return temp will never get high enough for long enough as the boiler will undoubtedly short cycle or stay in full modulation. This will be particularly problematic when the UFH is up to temp and requiring very little heat input. Fitting a buffer tank in between the boiler and the UFH would solve this, where the boiler would fire infrequently at higher temp to maintain the buffer stat set temp, whilst the UFH was able to draw as much or as little heat as it required. As your install stands, it's likely your boiler will just sit at a low modulating temp for the rest of its days, away from the range required for condensing. . Can you retrofit a buffer tank, say in an airing cupboard, where the heat loss would be useful? ( The E setting iirc is the sweet spot for condensing to occur ). Hope that helps

    Not in onoffs bath, I'm pretty sure of that. ? I'm sad now, happy thoughts please people. ?

    From the wider audience POV, this is a very informative exchange . Certainly separates what the difference is between simple 'good practice' and the actual regulatory requirements, with the latter, essential criteria, now well highlighted. I think that statement gives total clarity to the thread, thanks.

    For the uninitiated. . 1:38 secs in lol. Damn I'm old. ?

    I used to DJ, so can provide some hands-in-the-air music to throw some shapes to. ??????

    Hi, and welcome ?

    Yes. It's common for the PRV to fail and 'let by'. Water comes out of the copper overflow pipe at the rear of the boiler ( outside wall ), but can be tricky to catch as it often will do it when the system is hot and it evaporates away. Zip tying a clear bag over the end and making sure rain doesn't get in is the best way to see if it's been discharging. This could be the problem. An average system is around 10 radiators. It may be that the system doesn't have sufficient expansion and is causing the PRV to open. The boiler gets topped up to say 1bar, then the system heats up. The high volume of system water expands beyond the capacity of the boilers expansion vessel ( EV ) and the PRV opens to relive the excess pressure. The system then cools down again, when the heating turns off, and the water contacts. As there is water missing, the system pressure drops below the low pressure threshold and the boiler goes into lockout with low pressure fault on the display. How often are you having to top up, and how long has this been a problem ? Do you know if there is an additional EV?

    Looks the dogs bollocks mate ? Time to celebrate ? ??

    @TerryE Dont you have a hideehole where you could remotely mount the cylinder ? Or is it out of sight where it is?

    All for £40. ? Cheaper than shoplifting!

    I think @Temp's point is a valid one. Stainless clips are easily sought, and as Peter says, there are correct and incorrect types. This isn't at you terry, this is about ensuring you and jan have a safe and reliable installation, hence you posting it accordingly for comment / approval. . Is the pipe sleeved where it goes through the wall ? Apologies if you've already answered that.

    I assumed this would have been eliminated ?. Good point ? When the combi was fitted, did they fit new rad valves to BOTH sides of EVERY rad? How many radiators?

    Sentinel Leak Sealer is what you want. . Very good stuff and works lightning fast. Dose and run the heating for an hour as hot as you can get it, then after the leak is cured, drain and top up the inhibitor.

    Use this for sloppy joints. Sorry for the late heads up

    What he said. ?

    Hi @A_L. Thanks for the input . Can you give us a brief in the 'introduce yourself' section please ? . Many thanks ?.

    I think they'll be more than happy to just leave you the tails sticking out for you to connect up as and when. One less thing to distract them from the important stuff .

    Yup. Scratch it up with 40 grit and use the proper solvent weld cleaner before the actual weld. Clean is the rule.

    Can you easily get a duct in now? Change of £300 notes isn't to be sniffed at. It's certainly worth a second, or third thought. Btw, it's a lot more than running 2 pipes . Blow off, condensate, cold fill and associated cabling. You can only future-proof so much mate. Maybe toss a coin and let the queen decide. ? ??

    ?. That looks awful familiar ?? Patent pending me thinks lol. Manifold plumbing has a good few advantages. One which I found most useful is to be able to purge and set to work each individual run without having to pressurise the whole installation at once, like you have to do with series ( regular ) plumbing. Very handy indeed for those who mostly work alone for the finer jobs, like myself. Keep at it! Looking good so far ??
