    Vaillant ecoTEC Pro 28 flue query

    Having the above boiler fitted soon. Smaller (dimensionally) than the current one and wondered if it is permissible and possible to purchase a vertical flue extension to go before the 45 degree connector in order to extend up approx 200mm and re-use the existing flue hole? Would be ideal not to...

    Vaillant VCW GB 242 EH, no spark

    Tested the air pressure switch from the control board. Easy enough to test that is is open when the fan is off and closed when the boiler starts up, no need to remove the cover. As for the fan that was just my ears. I have no intention of playing with gas. This is not a replacement, this...

    Vaillant VCW GB 242 EH, no spark

    Having some problems wit h my combi, I've been reading through all the topics covering it here but I couldn't come up with a reason for me still getting no sparks. Apart from maybe a PCB has gone. So far I've gone through the fault finding procedure: - Neon lights up. - Voltages are good...

    Vaillant Ecotec 831 noisy heat exchanger

    Just to give an update so you know how the story ended: I called BG after 11 days were up and asked about my 7-10 days water test, and was told "Oh, it could take up to a month to get results back". I was not best pleased, and spoke to their customer care team who has supposedly got the...

    Vaillant Ecotec 831 noisy heat exchanger

    To keep everyone updated on the story, my engineer came back to take a (crystal clear) water sample, and now I have to wait 7-10 days to get the results back. If it comes back okay, the next step will be BG replacing the heat exchanger. I asked about copper paste, and he said that if you're...

    Vaillant Ecotec 831 noisy heat exchanger

    BG is such a big company, they need a lot of people. They ran into a lot of trouble a few years back by simply not having the staff to take on all the work they wanted to do, leaving a lot of people having paid for a service they didn't receive. They need to keep recruiting and training people...

    Vaillant Ecotec 831 noisy heat exchanger

    Well it seems I did by searching around and asking here to get some experienced opinions by people who knew exactly what the problem is, as opposed to my BG engineer who had never heard the issue and didn't know anything about it. Who didn't even take a water sample while he was here and wants...

    Vaillant Ecotec 831 noisy heat exchanger

    [/url] No it doesn't. Sounds exactly like this: www.youtube.com/watch?v=5lVMHDU8dAY though it's anywhere from every couple of minutes to a dozen times a minute depending how it's heating things up. It's a clanging/clunking sort of noise that stops once the boiler is hot or cold. In this...

    Vaillant Ecotec 831 noisy heat exchanger

    That's exactly my point. He's the expert on site, but he deferred against his own opinion in favour of someone down the phone, without even so much as taking the lid off the boiler or looking in the filter. I've asked here and been told it's definitely copper paste for metal expansion, he...

    Vaillant Ecotec 831 noisy heat exchanger

    Are you talking about this as a general cure for this kind of thing, or are you talking about this boiler model specifically? It would be really good if I could tell him that he needs to put copper paste between the exact components to fix the problem. Otherwise I can see myself going...

    Vaillant Ecotec 831 noisy heat exchanger

    I wasn't completely happy with how he relayed the fault. He described it as "tapping" to Vaillant, which to my mind is underplaying it because I consider it louder, and it ramps up to proper clanking and clunking where it sounds like someone hitting the boiler from the inside with a small...

    Vaillant Ecotec 831 noisy heat exchanger

    No he won't - he'll be doing a water test and then no doubt trying to get someone else to powerflush the system again in a couple of weeks time. Would have been useful to have known about copper paste before he turned up so I could have at least suggested that to him. Still he did call...

    Vaillant Ecotec 831 noisy heat exchanger

    Well he was a young bloke and open to suggestions, so he didn't just instantly discount it. He claimed not to have ever heard a boiler making the noises mine is making as he was expecting the much louder banging you get on a sludged up boiler. He did say it sounded like the noise old rads make...

    Vaillant Ecotec 831 noisy heat exchanger

    Well so much for the easy fix! :? BG man turned up and said it was too quiet to be sludge in the system. He called Vaillant who disagreed and said it was sludge just starting to build up in the heat exchanger. BG man has to come back to do a water test to see if the repair or the heating...

    Vaillant Ecotec 831 noisy heat exchanger

    Out of interest, could this have been caused by changing our old lead water mains (51 years of limescale) to a shiny blue plastic pipe? Would the increase in the water flow rate mean the boiler needs to be rebalanced for it?

    Vaillant Ecotec 831 noisy heat exchanger

    I've got a British Gas guy coming tomorrow as they support the whole system, not just the boiler. I'm glad it's a simple fix, but can you tell me what I should say to him if he claims it's just supposed to be that noisy? Apparently some Vaillant service guys have been telling that to customers...

    Vaillant Ecotec 831 noisy heat exchanger

    We had a Vaillant Ecotec 831 installed about nine months ago and have had no problems until a couple of months ago. Since then, the heat exchanger has been making loud clicking/clunking/popping/cracking/clanging noises as it heats up and cools down. It's loud enough to be heard through the...
