@ 8:55 Using hoses instead of pipes for viessmann boilers apart from the only real benefit + probably a slight reduction in water noise in the installation: water goes through the hoses more easily there are other "Benefits": the hoses collect dirt from the installation + that's how you realize the installation you need to be cleaned. Connecting the hose to the back of the heat exchanger is another great idea from viessmann - it helps to keep you in shape ... + tests your patience

[@AllenHart999]

Other countries such as America has always had copper pipes.

Thanks for sharing Al👍🏾

Thank You

Good informative video Allen. I don't install viessmanns or really service them so I haven't seen the insides of many, it's really simple how the prv and condensate are joined within the boiler. Makes me wonder why other manufacturers don't do it. I think alpha are the only other manufacturer I can think of that do.

[@AllenHart999]

Hi Craig. First of all let me thank you for all your continued support as a member. I actually have a new Alpha here to install. Thanks.

[@AllenHart999]

[@robiddon]

Great video thanks. I have the same boiler and it's heating the rads when I have hot water going so I think my diverter is stuck I feel a lot better about taking it out and cleaning it now.

[@AllenHart999]

I am sure you will phone a gas engineer or plumber; clearly, it wouldn't and isn't a DIY job. Thanks.

[@Honest_Reviewer.]

Excellent video. Can you replace the rubber hoses with copper?

[@AllenHart999]

No, unfortunately not, The new boilers have been updated to copper though. Thanks.

[@SalimKhan-gk1fh]

You don’t need to change the rubber hoses to copper on a good clean system they don’t give any issues mine is into year nine with original hoses

[@AaronThibeault]

great breakdown of the boilers components, i got one installed in my house this past year. Recently the boiler locked up and gave me a F4 code, the boiler wouldnt fire up at all. the installer adjusted the exhaust flue so that it was on an incline and that fixed it it seems what could cause this to happen? The boiler wouldn't fire up before the exhaust flue was adjusted from horizontal to an incline, When it was installed the air intake and exhaust pipe were installed parrellel to each other with no incline and vented out the house, does that this make sense? Thanks great video!

[@SalimKhan-gk1fh]

Excellent video Allen if I remember right you dismantled this boiler sometime ago? It was the one with the red wax seal still on the gas pipe ? these are a great boiler to work on very easy to dismantle and bring back to life it’s just a shame people don’t service them properly you see so many where they haven’t even bothered pumping up the expansion vessel, after a good service and clean out they always run like brand-new again even if seven or eight years old I have just done a year nine service on mine and it still hasn’t got crunchy hoses yet! Up-to-date I have never had to buy any plastic grundfos components for these, The composite plastic on them is really brilliant not even prone to leaking

[@AllenHart999]

I cannot remember what videos i have done now to be honest, done so many lol. Thanks.

[@ciscoenerlorfrancisco3520]

sometimes the boiler gives me such a headache to diagnose the malfunction, that I want to dismember it like you did in the video... piece by piece... eheheh. Merry Christmas!

[@CommercialGasEngineerVideos]

Merry Christmas all my fellow plumbers especially those working through the holiday season. Have a good one.

[@larryaok]

Great video, have you a video or information on changing the circuit board on that exact same model ? Thanks in advance

[@Brijoolz]

Has big issue with one very similar. One of the 4 pipe ones ( although the installer had blanked off the dhw primary pipes). Started with high limit fault. Changed the stat. Poor circulation. Called Viessmann. Advised by them to change the pump. Changed the pump head. Just as bad. Called Viessmann. Advised to check heat exchanger. Took it out flushed it, and the hoses , then all the hydraulic unit. Something looked wrong on the back of the pump casing. Asked if the disc was meant be at an angle ( not flat against the impeller). Put on hold, then I’m told that they’ve had problems with the block, and I’d need a new block.(£400 if we supplied it ). Client didn’t want the installer to come back as we were their service company and they didn’t want to open an account with the local Viessmann service agent. Very poor back up in my opinion. I’m sure the job had a massive loss on labour. Not my first choice of boilers.

[@reliabill87]

Great video, can you do a video putting it all back together?

[@AllenHart999]

No idea how to do that lol. Thanks.

[@reliabill87]

Yeah I was just kidding, it was just funny how you were just tossing all the components in the boiler 😂😂😂, never the less brilliant video P. S. I am glad you have some humour

[@leaturk11]

[@AllenHart999]

Thank You

[@dogwoodtube]

Thanks Alan seen a few videos and unfortunately had a bad plumber around who wanted to rip me off 800 pounds for change of heat exchanger for hot water and 450 pounds to flush a system with 8 radiators 4 of which I had taken off for decorating and was surprised how clean the water was also magnetic filter didn’t have much dirt in although the boiler is over heating so I think boiler is blocked but I will flush with mains water after seeing your easy to understand videos and I think boiler will work again

[@davep4703]

Hi Alan another great down to earth educational video so question Maybe you could assist me with this question. I have been watching you dismantling several boilers and am trying to determine the following. Description of 'system type condensing boilers' , returning water from the system (radiators) enters into the 'Secondary heat exchanger' picking up 'residual heat' from the the 'flue gases' . Where exactly does the secondary heat exchange take place, I can only see the return water entering the main heat exchanger. Regards Dave Porter

[@AllenHart999]

This video should cover everything you need in great detail. Thanks. kzbin.info/www/bejne/lXrKeH6Vqdx2d5o

[@kevincranfield5235]

Secondary heat exchanger or recuperators sat between the fan and the flue exhaust outlet. They were joined via pipes internally to the main heat exchanger. Newer versions have a similar setup but rather than the primary water flowing through the secondary heat exchanger on the flue outlet, it is the mains cold water that takes the flue heat and then passes through the plate heat exchanger where the heat is topped up to produce hot water

[@kevincranfield5235]

The rubber hoses allow oxygen to be absorbed through them and therefore can promote iron oxide build up, but I had a little conversation with heat geek and he says the positive charge from the hydrogen particles in the water react with rubber and that is why they block up.

[@kevincranfield5235]

🤷‍♂️

[@AllenHart999]

He used to say the hoses were amazing and do not cause an issue.

[@AllenHart999]

Never been any doubt that the hoses cause oxygen ingress in my opinion though. Thanks.

Great video . I here viessmaan now don’t recommend the use of inhibitors has they may rot the rubber hoses, When we had one fitted some 4 years ago , they were saying it’s essential to have the inhibiter in the system for the 10 year guarantee to be valid, now the goal post haven’t been moved they taken them away. Do you use the inhibitors or not . What areYou’re thoughts Allen .

[@suheilhanna873]

So if you have to replace the diverter valve, then we need to replace the whole right hand block??

[@edmetcalfe8974]

Also, have you really got to take the fan and gas valve out to get to the condense trap?? That can’t be right but I can’t see any other way of getting to it. 🤷‍♂️

[@AllenHart999]

I always strip Viessmanns down every time so not an issue. Thanks.

[@1Monaghan]

The fibre washers on gas valves are they specific gas rated fibre washers or can you just use any fibre washer that fits correctly?

[@AllenHart999]

I use the Viessmann one when needed but its definitely worth checking it. Thanks.

[@grayhalf1854]

I've got that boiler! Had it ten years without so much as a service...! 😁

[@grayhalf1854]

I'm a bad bad boy, I know. Just installed a Fernox TF1 Sigma though, so I'm making a tiny bit of effort to keep the system in good order...

[@grayhalf1854]

And actually, although I probably shouldn't admit to it, I've lived in 2 flats since 1997 and never serviced the boiler in either property. Over almost 25 years it's a decent saving! You have my permission to wag your finger dissaprovingly at me Allen 😁

Hi Allen, Great videos!. I have the hot water issue ( hot / Cold ) . I replaced the heat exchange plate, I cleaned the 2 rubber hoses, I removed "kilos" of muck but it still going hot / cold. Heating side works perfectly fine. The pressure going up and down ( between 1.2 and 1.8 ) when hot water is on, temp goes up , stops, then down, starts again... What else I could check?

[@kpkp349]

Can anyone explain how the fan is 'proven' on the newer boilers without air pressure switches? I'm assuming that modern fans send a signal to the p.c.b. once they are running which can then carry on the sequence of operation. Any specific explanation would be much appreciated. Thanks.

[@s.o.a8520]

hi allen how can i contact you? really need your help. rad wont heat up. been trying different things for 5 weeks but no luck. heres what ive done so far: 1. released air 2. removed air lock. 3. changed both valves. 4. used sentinelx400 and 800. 5. flushed system many times. once i took magna filter off, connected a hose and drained each rad individually but when i got to that rad pressure was rising but nothing coming out of return so i opened up another rad and water shot out! i suspect theres a blocage somewhere but pipes all all under floorboards! what can i do. is this something you would do? many thanks

[@rayc1503]

It's quite frustrating when a customer or builder drains the system to put in or move Rads. On refilling the system most won't bother flushing or reinstating inhibitor. If the system is filled with standard mains water. It really does need inhibitor. The water standards in Germany only allow for deminerlised water to be put through their systems. The importance of good system water quality contributes to the longevity if the boiler.

[@AllenHart999]

I went to Germany and asked them about the miff of demineralised water, They told me they use both methods, They also use inhibitors
