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.

Removing the whole hydroblock to replace the p2p seems like a light bulb moment Never will lose a rubber seal again Respect lads

Nice one Allen Roy. Never thought to take the hydro block out in one piece. 👍👍👍

Great video, straight forward to understand when it’s done like this, well done Roy keep them coming.

great video roys a great trainer always got time and a question is never a stupid question

I will renew my ACS at Viva Training due to Roy’s professionalism and knowledge - very good hire for your training centre!!!

Hi Allen, Thanks for the great videos! Really admire the amount of time and effort you put into your channel. Roy is a great teacher !

Roy, you are a fantastic trainer. So easy to understand what you are saying and doing.

Great video Allen and Roy, very informative and helpful to anyone learning the trade such as my son, keep up the good work 👍

Thanks Roy and Alan, full of little gems.

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 Allen and Roy. All the best.

Excellent video as always many thanks to Roy for his expertise and of course Allen 😁

Got first right hand block tomorrow morning perfect timing thanks Roy and Alan

Cheers Roy 👍 great job, always explains things clearly!

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

Grand work you're doing there fellas. 🙌 to Roy, Allen and the rest of the team. Always a pleasure to be learning something new 😉.

Top of the range.. great tip on bypass thankyou alan + roy for these informative videos 👏

Thanks Allen and Roy great job you guys brought so much knowledge for the trade thanks again

Great video Roy .wish there was more trainers like you

Alan thanks for the video and Roy thank you for your great teaching qualities

Thank's guys another fantastic video very informative . Allen is the man to go too !

Very well explained nothing left to chance

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. 😀

Thanks to Allen and Roy great 👍 video. Appreciate it guys. 😀

What an absolute wealth of knowledge and a Wednesdays fan aswell. Thanks for the video gents

Oh god you make it look so easy UCL professional I have subscribed

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.

Nice one Allen and Roy 👍

Great stuff Allen and Roy

Thank you Allen and Roy.

As we all know the Hydroblock doesn’t come out anywhere near that easily on an older boiler crammed into a dark cupboard !!!!

Excellent presentation, I would like to see an ideal boilers one next please. 👍

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

Fantastic video brilliantly explained.

Very thorough stuff this Alan. Ta!

As usual, another great video Thanks

Brilliant lesson, thank you for your time

Great alan a Roy thanks for good information great

Really good video, explained really well nice one lads.😊

Another top video. Think I’d need 100 photos and big Roy’s help to put all that back together 😳😂

What a life saver!!! Amazing video

Alan and Roy legends💪

Great video as always Allen I’ve taken a couple if these out before, had a nightmare, but this video would of definitely helped me👍🏻

Thanks for the great videos!

Excellent video👍

Top video Allan thank you.

Great video thanks both 👍👍

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 👍

Great presentation

Great video well explained too. Cheers 👍

Great video ,thank you very much sir 👍

Great vid. thanks guys

Wish this video came up first. Very good. Thanks

Excellent I would like to see the testing plate HE video! Well done guys

Great video!

Great video 👊🏼

Great video.

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.

So understandable, respect

Great .. very helpful .. I have to do one these today .. get the plate out

Very good video

hi Allen great video

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

Thanks for the info

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

great video guys , i didnt realise that there was a valve in the bypass

Cheers mate Worcester gives me nightmares 😂😂

Great video as always I've done this but boiler won't fire up afterwards any idea what I've done wrong x

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.

good man!

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 😁

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 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.

👍

So much easier on a dry boiler

Would it be easier to remove the hydro block to change the prv ? Thanks

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

Thanks Lads

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

🤩🤩🤩

Great KZfaq video Allen. Can you do the same thing but with a vaillant boiler ?

All that just to replace a prv. Good video but I'll stick to baxi

Great vid guys, whoever designed the greenstar was on crack 😀

Hi it seems that a part was on the kitchen desk. It's called a damper,from a Worcester 24 green star. Where should this been placed.

Was working on one of these yesterday that boiler was designed to have razor blade edges sliced my knuckle like butter

Thanks for the training.

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

👍🤓👍

Is the hydroblock housing male where it meets the plate heat exchanger holes( female) or doesn't it enter just surface contact with washer?

Where is your training center in UK?

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

I'd just leave the whole lot out for the scrapman.

More vids on Vaillant

💫💫💫💫💫

Looks like a time machine

Great video Allen and Roy, Horrible strip down for a basic job like PRV change How about a video on balancing radiators with Testo clamps

I ned only how to change the pump

ferroli package burners

Halifax eh, that’s handy I usually resit my ACS at Colne but Halifax is much easier Where about s in Halifax are you
