VIESSMANN VITODENS 100 - Whats Inside - Full Strip Down

[@jeffmcbride6766]

That was a simple yet very good look at how to expose all the components. Thanks again

[@jeffmcbride6766]

Thanks for sharing your knowledge. I appreciate the way you repeat yourself at times to hi light things

[@danielwilliams3978]

Great Video Allan. I liked the way those Viessmans come apart. Very good video

[@twiggacott]

Thanks. Handy to see how it works and very useful as I'm not sure our service guy does a full clean. Never seen him remove the burner as far as I can remember

[@manofweed1]

No. I think they just test how efficient the gas is burning. If good they leave well alone. If it's not to specification then they delve deeper into the workings to find out why not.

[@paulrossiter9567]

Thankyou Alan....I have a vitodens 100-W to service this week and this has been very helpful as an insight 👏👏👏👏 they look very good to work on unlike many other cramped boilers. ⭐️⭐️⭐️⭐️⭐️

[@keithjackman1]

Hi Allen , All your videos are worth watching . keep them coming .

[@AllenHart999]

Thank you for your kind words.

[@davidalearmonth]

Great video, thank you! Just curious, what is the black deposits in the unit that hadn't been serviced? I had mine cleaned a year ago, but then had a bunch of this stuff in there now, and just wondering what causes this. The technician says that in the past I didn't have it serviced often enough, and so it might be leaking?

[@daveramsay8598]

Good video. I just out in a new vittodens 100 combi. Interesting to see that Viessmann continue to improve their product. Also good to see effect of not servicing a boiler.

[@bugz7149]

Mine is a Vitodwns 100, the upper housing is completely surrounding the inner parts, and also there is a plate separating the upper round heat exchanger together with gas connection, below the separator plate is the pump and the hot water heat exchanger, and in this model it is more difficult to take this hot water heat exchanger due to less space to maneuver, and i can not find the name plate of this model, iwould like to see the complete dissassembly of the specified model and maintenance, thx

[@bugz7149]

Please dissassemble the lower part on the right boiler!!! I need to see how pluck out the hot water heat exchanger

[@neilo1967]

Excellent videos, do you have one that shows how to remove the plate heat exchanger out of a Vitodens 100 WB1B?

Hi Allan I got viessmann combi boiler.F2 keep come. Can you do something about it. Thank You.

[@Pro-nj4uu]

I agree. I don’t get called to many of these in our area which means 1 of 2 things a) they don’t break down that often or b) not many have been sold here !

[@AllenHart999]

The brand seems to be doing well and growing so you might start seeing more. Thanks.

[@Pro-nj4uu]

Hopefully, they seem well built and are easy to work on compared with some ! (Ferroli service agent) need I say more.

[@AllenHart999]

Bet you see some very nice installs lol.

[@Pro-nj4uu]

Yeh shocking lol. Said boilers don’t work very well even when fitted perfectly, poor installs have no chance! We are also agents for Vaillant/Glow-worm so not all doom & gloom lol. Nice chatting Allen, all the best.

[@AllenHart999]

Nice chatting and thanks for your support.

[@gm2407]

these look similar in layout to the baxi. I like that you have a near full cover to lift off, it gives me more confidence the housing will remain in tact.

[@adamlake6650]

Hi Allen, these Viessmanns are decent units, now as you know with the upgraded pipes from the primary they are my boiler of choice, my boss prefers Worcester’s but I’m a viessmann man myself 👍🏻

[@AllenHart999]

Viessmann are much better than any worcester imo. Thanks.

[@adamlake6650]

Has it got weather comp fitted to it?

[@mmaenthusiast7605]

Thank you Alan for the videos, they are of great help!! I work in London and just don't come across enough of these boilers.. worked on 2/3 in the last 12 months so I naturally prefer to work on Worcester's although they're a pig of a boiler to work on for quite a few parts. I'm a vaillant man all the way!

[@Hatfullofhollow]

Hi Alan, thanks for the video which is very informative. Is it possible to replace the expansion vessel if leaking?

[@florin12428]

Hello...viessman or vaillant?

[@daviddavues1677]

Do you need to fit a new gasket, every time you strip down the burner on boiler

[@Mark_Won]

I've got a 100-W 26kW Combi. The call for hot water seems to ignore the flow sensor, it's purely temperature based. Because of this it fires up several times in the night to heat the tiny amount of DHW in the plate exchanger and then turns off (all at zero flow). It's a really annoying. I've tested the flow sensor separately and it's all in-spec. Is this the intended operation of the boiler or is there a problem with the main board?

[@goodlife793]

hi what to do with the gas valve if it does not open?

[@yeknafaskesh1257]

Hello Allan, thank you for taking the time to make the video. It was very informative. Good job.

[@huntermedea8536]

HI Allen . absolutley love this channel , way more info than on th course! I have a question and perhaps you could help. sadly you didnt fully strip the other boiler , combi 30kw , as it would answer my question. i had some building work done and boiler was removed and stored in the garage for over a year. had this re fitted this week , but it seems to be missing a part at the back. Pressure relief valve at the back, has black plastic pipe connected to it , and it hangs freely at the back of the boiler. when i checked on newer model , it is linked internally to the discharge grey flex pipe , but on my model (vitodents b1b 30kw 2011) , it does seem to be loose and i cant dinf where they both would link. searched on viessmann manuals and no luck. could you help please?

[@Sashstrij]

Thank you.

[@michaelthompson3381]

How do you get to the Air Vent Valve on the Boiler on the Right, mine is leaking water ?.

[@AllenHart999]

If you take the case off you will need a gas safe engineer as it will need testing afterwards. You need to drain the boiler to remove the air vent, It then just turns and pulls out. Thanks.

[@MrGoonerguy]

Hi Alan ,how do you remove the trapon these? Ie to clean it? Can you do it from underneath?

[@stevehouse3904]

Could you show the best way to change the pressure relief valve in situ, cheers.

[@Pro-nj4uu]

Those h/ex’s flexi’s cause problems, as with any flexi, the muck loves them, however these are extra long !! They’ve been upgraded to copper pipes now I believe. Great videos btw. Thanks

[@AllenHart999]

The new ones are copper now and much better in my opinion. Thanks for watching.

[@gerardlong5675]

Nice video Alan showing how easy these boilers are to work on. That wb1c can’t be that old, pity seeing it in that state! Must have had a lot of use in its few years and no cleaning judging by the condition.

[@AllenHart999]

They are really easy to work on and very good boilers. Thanks.

[@spencerwilton5831]

do you rate the viesmann vitodens 100-w open vent? I'm guessing similar quality build with less to go wrong so a safe bet? Just wondering if it's really worth the extra expense upfront- thoughts appreciated!

[@AllenHart999]

Spencer Wilton in my opinion the Viessmann 100 compact heat only is the best heat only available. Thanks

[@demirunlusoy2795]

Do these boilers (B1B and B1C) use the same PCB, and will their PCBs fit to each other ?

[@AllenHart999]

I do not know the answer to that , Sorry.

[@akamirosun]

Allen could you explain why water heater (in model of the left WB1C ) is plastic? Is that mean there is no water heater function in this model? Or they just use other material. I'm owner WB1B and have this plastic part in my model so do my WB1B is combi and have water heater funcion?

[@AllenHart999]

Not really sure what you mean but they are both combi boilers. Thank you so much for the comment. Happy new year

[@monstermarkone]

The WB1C on the left is a system boiler (unless it’s been modified after installation). If it was a combi, the black plastic ‘blanking plate’ part would be a stainless steel plate heat exchanger. The first 7 digits of the serial number will confirm what boiler type it is if you put them into the Viessmann spares app.

[@Listermintsluesh]

Viessmann looks like it's made well I've an old Worcester Bosch and although much bigger looks cramped inside. Time for a new one me thinks.

[@SalimKhan-gk1fh]

Hi Allen. It’s nice you to put this video up. These are an excellent good boiler I’v been using fitting viessmann the last 10 years now. They are one of the best to work on very easy access to everything. you can take the whole burner assembly out in two minutes on a service. All the ones I fitted during that time have been very reliable they are extremely quiet in operation and most people have noted the gas bill go down. Their worst enemy is a dirty sludgy system water And shoddy installations. Only downside to viessmann are they are quite pricey on spare parts but fortunately never had to buy many as they been quite reliable ! The boiler is only scrap on your wall as it has never been serviced properly. Good video but I wish you stripped it further down To show the quality

[@AllenHart999]

How much further do you want me to strip it, if you look on one of my other videos I cut the heat exchanger up to show how big the waterways are inside them. Thanks for taking the time to comment,

[@SalimKhan-gk1fh]

Allen Hart . Thank you Allen. Yes you are right my apologies! I’ve just had a look and saw your other videos the one you made on the heat exchanger quality is absolutely first class! the steel must be good As it seems it was not easy to cut through? Good videos mate thanks for putting them up! Keep them coming please🙂

I have a new one on heat exchanger coming soon, as soon as i get the last one i need. Thanks.

[@SalimKhan-gk1fh]

Drink Water. After using them last 10 years I will definitely go for the viessmann they are very quiet.efficient and have the best he exchanger currently on the market.check them out online they have won the which best boiler, aswell

I would say the baxi megaflo , Viessmann is also good.

Hello. I have a strange problem with my Vitopend100 series. Hot waters works fine, but when I try to start heating the flame starts a few seconds, then it stopps and I get a sound like water is circulating but theres no heating whatsoever. Pressure is fine, no problem with thermostat, no error from the unit. What can it be at fault ? Could it be the thermal sensor probe on the heating side ? That's what I suspect. Any thoughts appreciated.

[@joshnichols9972]

Did you find the issue? My vittodens 100 is not heating properly and how water is fine as well. Waitin on a tech next week.

[@ForgottenGamesAndMods]

@@joshnichols9972 Yes, it was the 3-way valve. That's a little expensive to replace, about $125 here.

[@joshnichols9972]

Ok I can deal with that. 125$ USA I have him comin to clean it out and fix anything it may need

[@ForgottenGamesAndMods]

@@joshnichols9972 This is one of the more expensive parts that can break. Thermal sensor on the pipes are around $50 and relays around $25 at most. Some people replace the 3-way valve with an alternate one. These 3 parts have the highest chances to break for this model. Everything else should be long lasting. Replacing the 3-way is not hard, it takes a few minutes for an experienced person. Good luck and have a long lasting boiler.

Veissmann is all I fit. Vitodens 100-W is a great boiler especially in Hampshire where the water is so very hard! The only major gripe would be the flow and return pipes get crunchy and then screw up the plate heat exchanger.

The heat exchanger is one of the best in the industry. Good and bad points with most boilers but these are definitely good boilers imho, Although they do need care and attention. Thanks

[@dan123collins]

Looks like a lot of plastic bits inside and rubber pipes to the heat exchanger ? Don't seam like these would last ? The house we moved into has a ATAG Q38c and it looks quality inside, nothing but stainless steel and brass, it has a small 14ltr DHW cylinder inside the boiler itself so it doesn't need to fire up if only a small amount of hot water is needed and doesn't have a plate heat exchanger to block with limescale etc Any other manufacturers doing a similar set up to my ATAG ? Not a gas engineer but interested in this field.

[@AllenHart999]

Atag ? The Atag boilers are very good but the pipes inside are not stainless. The are carbon steel with an external nickel coating, the end panels on the Atag are also aluminium.

We had a flow problem with our Vitodens 100-w boiler and we traced it to a blockage in the heat exchanger so we bought some washing machine descaler and pumped it into the heat exchanger and left it for about an hour and then flushed it out, this solved the problem the heating and hot water now works fine again, Please note the heat exchanger is made of stainless steel not aluminium.
