How To Strip Down A Worcester Bosch Boiler. Roy from Viva Training Academy shows us the importance of reading the instructions and removing components on a Gas Boiler.
This saved my bacon today, replaced plate heat exchanger, right hand side block and manifold, as well as PRV. No way I'd feel comfortable enough to tackle this job without this video.
Allen this is probably the best content you have uploaded with viva training academy and Roy etc and all of your content is of extremely high quality. Absolutely loving the videos of boilers being stripped and each part being thoroughly explained how it works and what they do. You and Roy are wizards. Keep up the great work. Thank you.
Thank you so much for this video. The company responsible for my boiler insurance with Domestic & General have to come back and replace the PRV on my Greenstar 24i Junior. I now know that, after shutting off all the radiators and draining what's left, a competent plumber should be able to remove the hydroblock relatively quickly in order to replace this part. I've seen several videos that attempt to replace the PRV without doing this, and it seems far more trouble than removing the block. While I wouldn't consider working on the boiler myself I really do like to know what is being done, and how it should be done.
Great info again. Retirement looming after nearly 50 years. Wish I'd had your backup years ago. You never stop learning. Advised a few newbies to tune in. Well done x
Thanks very much Gentlemen, very useful to understand the components more. I’ve removed 2 Hydroblocks on 24/28i juniors, not easy, but I had to refer to mi’s as well. 😀
You forgot to mention in little older Worcerster boilers, these plastic flow turbine starts deteriorates and cracks easily, so be carefull when removing hydra block in older boilers. Really good video. thanks
Excellent 👌 👌 👌 So well explained and honestly didn't realise how easy it is to remove the hydro block 🙄😂 Fantastic tips especially about the auto bypass. Just so impressive 👍
Amazing Allen how you get time to fit all these videos in. I'm 61 been in plumbing since 17 and at no time has there been better access to plumbing and heating today then ever. THANK YOU 👌
another thing to be advised about .. the washers that go in the top of the hydro-block are called Bonded Washers they are bosh specific they have little tabs do not try put the system back together without them. I am not sure where mine went if anywhere... but i did find broken Fibre washers which lead me to believe that was the washer needed.. which is wrong... cut a long story short after watching a few vids and visiting a few plumbing spares websites i found out about that the correct proprietary washer.. another side part is that you can use a regular bonded washer on the left hand block that does not have little tabs.
Nice video, Thanks for sharing the knowledge. But the writing was covering the actual stuff what he was showing please keep all the writing in a separate section so we can see what he is showing. Thanks again
Roy, fab video.. my right hand side plastic unit was all fured up with a leak. I drained and replaced the right plastic unit, the flow turbine, re pressurised to 1.5bar, (the diverted valve solenoid looks really low and doesn't raise more than 3 mm) and it will not turn on. Blue light mostly off, 1 blue light to two red lights. What amhave I missed / need to do? Many thanks Roy and team.
Hi Allen, thanks for your video clips. What are all the symptoms of a faulty bypass valve?This gentleman in the clip mentioned one of them already. What is the rest please? Best Mo
I would be interested to see common primary heat exchanger faults. Recently had an cast alloy heater exchanger on a Worcester Bosch RD32 split at the side that was not visible from the front. It would hold pressure when cold but when the heating was re-engaged it would slowly lose pressure and leak out about a litre of water in 24 hours.
Absolute quality demonstration of hydro removal and the explanation of all the components.....gotta be honest I never realised there was a valve in that bypass 🥴 Thanks Allen and Roy. P.s. your a genie with these Worcester’s Allen ...seen you strip these for fun 👏👏👏👏 Do you have any component testing from pcb videos 😁
Hi great video, just a quick question, is this the same setup on a Worcester Bosch greenstar 30i? I have a problem with my boiler, when the hot water is off the pressure goes over 3 bars but when the hot water is running it drops down to just below 3 bars. What can be the main issue? Cheers
Don't understand why they put the prv where they did, you can pop a baxi out in minutes, having to take the hydraulic block out just doesn't make any sense, and they don't come out as easy as you are implying, also you forgot to mention those unusual metal type washers that you can miss when to release those clips with the pump pliers, then you can't buy the washers and seals just enough to replace the prv, they supply a big bag with every clip, O ring and washer in the boiler around £45, I've got a big tin of the ones I didn't use. Even standard fibre washers won't fit as the male end has a little lip on it so you can only use WB washers and they don't give you any extra. I walked away from one of these last week that needed a new prv, just couldn't face it.
I have a P2P to change on the Greenstar classic the pipes go straight out of the valve into the wall so no chance of moving hot pipe out of the way, do you recommend removing the hydro block to change p2p
Hi Allen, do you (or any readers) know where we can buy a PCB for a Mains Eco fan please? I think it's also known as the fans 'speed modulation board' < it's positioned in the housing on the back of the fan... All we can find on the internet are Worcester fan PCB's - Cheers
Hi Chaz, unfortunately the fan Pcb is not available as a separate part, I know some of the Baxi engineers, just change the Pcb but have to take it from a new fan.
Great video again mate I’m currently on my gas course and I’m looking to get some jobs done in my portfolio I’m from Pontefract if you know anyone in the local area who can give me a hand let me know thanks my friend
