Another excellent video Allen! Informative and in-depth,thanks for taking the time in making these and uploading them for us these are a very high quality boiler and I’ve used quite a few myself last 5 to 10 years ,I just wanted to point out that after making enquiriesOn the plastic components inside these ,it turns out they are the same composite plastic materials that is used in the automotive industry i.e. water housings, let manifold and radiators, and they have proved their worth and reliability .I’ve never had one leak from any plastic component like you normally would expect from a Worcester ,vaillant ferroli baxi etc, even On a 13year-old boiler all the water housings are solid and not showing any signs of wear
Thanks.
Hey Allen
After watching several of your reviews and maintainance/ install videos I chose the viessmann vittodens 100-W 35kw combi to replace a Vokera system boiler that had a broken heat exchanger at 8 years old. Had the heating engineer install it last week. The unit is working great and much better than before though I think the HX was clogged up and performing poorly on the last unit. Hot water is vastly improved due to pressure as we had a tank on a half landing with a header c.1 meter above the showerhead so now get blasted with water. Heating is great and the unit performs as you have described. The heating engineer I used was trying to get me go another brand but I felt confident to stick to my choice based on your videos. Thank you for making these videos and giving good advice that end users can follow.
Glad i could help. Thanks for watching.
I fitted the new Viessmann 100 Combi at my mums house last Monday.
Great boiler to install and is hydrogen blend ready for when we get it in the Greater Manchester area.
I agree that it is better having copper instead of rubber hoses.
I think they are more reliable than rubber.
Excellent boiler.
Thank You- I am looking at converting from Oil Boiler to Natural Gas in the USA and Veissmann is looking like a good reliable brand. Thank You so much for the information and great explanations- looks very sensible and straight forward.
Hi Allen, I had one of these installed last year. When the guy from Viessman came to do the service I asked him which inhibitor I should use and he said none, don't bother as Viessman don't recommend using an inhibitor. What's your view?
I installed my first viessmann the other day, I usually fit worcester boilers (I know they're overrated but it's just what customers want and I've never had an issue with them), and I'm really impressed, I'm definitely going to be trying to use them as a preferred boiler from now on.
Good stuff!
Thanks very much for your comment, please consider subscribing to support the channel 🙂
The say you don't like the rubber hoses inside the boiler but have you had any problems with them ?? Just curious
Hi Alan, great videos. Keep up the great work. I’ve always liked the Veissmann boilers. Installed the old Vit-100 in mother’s & mother in laws. Only had one issue with one of them with the bulging and split on one of the rubber hose. Known issue that they can blocked up after a which, which is one of the reasons they switched over to copper in the new version. I’ve installed a few Ideal logics especially when ideal launched them after trying to recapture some of their market after the issues of the icons & isars. They were offering some pretty good warranties and pretty much lost faith in the over engineered Worcester’s and persistent splitting hydro blocs.
What I wanted to ask is what boiler is your choose as being the best out of all the available combis? The new vit-100 is a top choice if in large cupboard but what would you go for if the client wanted a boiler to fit inside a kitchen wall unit? PS I’m a supervisor for a multi trade maintenance company in Leeds, I’ve had my gas for 15 years but if I’m honest have not done nearly enough gas work in those years. I was originally a multi skilled plumber & topped up my skill base with level 3 plumbing & gas.
Dear Allen. Really nice comparison, thanks for the video. I have the older model the vitodens 100. It had its annual review today (all is good :)) and your vid came to my mind so I asked my service guy about the rubber hoses. He said that indeed the steel is more reliable and the rubber hose can be blown off in case the boiler overheats (sorry if I didn't understand correctly I'm no expert). However he said that in case some sludge gets into the boiler it gets stuck on the inside of the rubber hose while it would go through the metal one and could damage the boiler. He said that with the rubber hose he can easily check this by pressing the hose as he would feel the built in sludge on the inside of the hose. For me it is not an issue as I have 2 dirt separators in the system. I'm really curious about your opinion :). Keep up the good work and all the best!
Burrmorg ,Keep up with the servicing and check your filters regularly ideally twice a year and you will be fine, I have some of the older models in use and they continue to be strong in reliability and performance .have you had your Heat exchanger apart and washed out?
Thank you so much you saved so much money.
And n o w I have heating.
But I bit confused about temp but I will recheck this video again.
Thank you so much
👍👍👍
Older model Vitodens 100-W and definitely having problems with the rubber pipes degrading. Now seven year old and having its second clean out and new heat exchanger because of blockages. It's a WB1C
It sounds like your boiler is running on a dirty system I have about nine of WB1C boilers in service and all are doing well do you have a magnetic filter on yours??
@@SalimKhan-gk1fh Thanks for responding: yes we have a Fernox TF1 fitted but it doesn't seem to be collecting anything. Instead we are getting metallic residue in the heat exchanger and expansion chamber. The system was flushed through before fitting so I think I need to get a second opinion on the installation. Maybe the filter not fitted right?
Hello, I have the same Boiler at home and I want to make a connexion with The extension kit but I do not know where i have to put the cable. Could you help me Please. Could you explain to me.
Thanks you so much wish you have a nice day
Thanks Allen for all the informative videos. I have a 100W combi with the touch screen installed in New England. The unit was installed with an outdoor temperature sensor for weather compensation. However I do not see the outdoor temperature reading on the display. Does this mean the weather compensation was not set up in the system? Thx
Hi Allen ,Thanks for videos,just wondering what is the Danfoss Programme switch in boiler house, seperate to (Veissmann boiler) also states CH 1 and Ch 2. If I press 1 it eventually goes to 2. Having problem with towel rail in bathroom coming on when it is turned off ??. Is this boiler related ??. Thanks Gerry
I'm looking at a replacement combi boiler and favour the Viessmann boilers. My boiler is in my garage, so I need to see what room stats are available, preferably an RF type as a had wire would be problematic. Perhaps a video on that would be very helpful.
Great suggestion!
Thanks for video, really helpful.
Quick question - On the new model how do you put the heating on if the WiFi was to be down in the area as we control ours via a Google nest. Is there a way to put it on via the touch screen as the screen only sets temps and doesn’t seem to physically fire the boiler?
we have the Vitodens 100-w with a separate hot water tank that boiler fills. The display does not show eco mode or comfort mode only the temperatures. Is there an easy fix?
They're a great boiler. Well designed and very quiet too.
Yes very well designed great gas efficiency and most of my customers have noticed how quiet they are too
Which one do you have?
Will a Viessmann 100 boiler work with Poly B tubing?
Hi Allen. How do you check the pressure bar on a vitodens wb1a. There is only two knobs no pressure gauge on the front. Thanks so much
Installing the Vitodens 100-w B1-HC 26kw ( system boiler). Was a bit disappointed it was a four pipe configuration, utilising a Viessmann internal diverter instead of my usual external Honeywell S-plan. Also I needed to purchase a Viessmann "cylinder demand controller" to my Gledhill unvented. This was extra cost as the DHW side is only on volt free contacts and not 230vac like the space heating. Hope this feedback helps others.
You wouldn’t of needed that if you installed a Viessmann cylinder.
We have this model, installed in 2018. Been great , but last week the expansion vessel failed/perforated. Not cheap to replace and part not covered under the 5yr. warranty so a bit disappointed that it should go so early in its boiler life.
Why wasn’t it covered?
@@AllenHart999 Our heating engineer said it's classed as a consumable item apparently.
Hello. I wanna buy viessmann vitodens 100 w 26 kw , what is your opinion about this?
Hi Allen, thank you for your technical reviews. They are very professional and credible. I am thinking about installing this Viessmann Vitodens 100 but I realized the new model has just come out. Are you planning to make a review of the new model? Thanks
I got the 2021 version 100-W 35 kW combi installed start of May 2021, It is working well on Opentherm for me, this 2021 version of 100-W allowed to set max CH hot water flow temp while using opentherm for boiler settings. The Vicare app allows me to remotely see if the boiler burner is operating and what modulation % , and the flow temperature set point called by the opentherm controller (I am using evohome) and what flow temperature reached . I find this very useful as the boiler is in the loft . The turn down declared is a low of 3.2 kWhr , but I suspect is lower as the % on the burner goes down to 8% (indicating 12.5 :1) , I suspect that Viessman dont want to declare this because the turn down capability gap between this and the far more expensive 200W (1.9 kW/hr, ie 17: 1) becomes narrower. I am not sure what justifies selecting the 200W , because the 100W now have the lambda pro combustion feature of the 200-W and does not have does rubber stupid hoses . One neg point however there is no longer an mini expansion vessel included inside the boiler as plastics supposed to be rated for 30 bar (I would still fit a mini expansion vessel, I dont have that much fate in plastics as they age > 10 years )
Note added, I originally was going for the 200-W due to its best in market turn down , but I wanted opentherm which the 200-W , I learned , does not strangely cater for . The 2021 100-W , ticked 95% of the boxes for me of the 200-W and did not have the rubber hoses (which seem a odd design choice for premium boiler),
Low hot water pressure (kitchen bathroom etc) and no hot water, heat exchanger the bottom one is an issue?
Thanks Alan always true and honest
Hello, I have a Viessman Vitodens 100-W Combi system. Installed over one year ago. Noticed in the last week a sound like maybe condensation fall onto the burner, I think. The burner was cleaned out and the condensate trap too. Notice this sound more when boiler is on medium to high fire. I can send you a video. Could it be a venting issue or maybe running temp not high enough.
looks a good one, I am keeping notes as at the back of my mind I am thinking my 15 year old Vaillant turbomax boiler is bound to die soon, especially as this used to be a council property and I am sure nothing has ever been opened up and cleaned out like the heat exchanger, probably just had a quick check with the flu analyser.
Lots of good boilers these days. Thanks for watching.
Alan is it possible to change the steepness of the "weather compensation" curve? On 2018 ones the setting does not work. They have fixed the software for 2019 ones. Do you know anything about this? I am going to ask Viessmann for a new board.
No idea sorry.
metallitech hi call viessmann,they will come out and reprogram it for you, they done mine no problem
Great stuff Allen
Thanks for the video Alan. I have a mobile thermostat for this boiler (same manufacturer) but I can't figure out how to turn the boiler off completely unless I do it manually at the machine itself. Any advice is much appreciated. I have read the instructions fully 3 times and can't work it out! Any videos on operating the thermostat? Thanks

Translated with google because I don't know English.
Hello Good afternoon, I think it's a great video and very well explained.
Please, I wanted to ask you a question: I have one exactly like that (100 W B1KE digital) but in my case at the point where you regulate the temperature of the heating I see that you can raise it to at least 80º but in the case of the I can't go up to 24 for mine, could you tell me what it could be due to?
Hola Buenas tardes, me parece un video estupendo y muy bien explicado.
Por favor quería hacerle una pregunta: Tengo una exactamente igual que esa (100 W B1KE digital) pero en mi caso en el punto en el que usted regula la temperatura de la calefacción veo que puede subirla al menos hasta 80º pero en el caso de la mía no puedo subir de 24, ¿Podría usted indicarme a que puede ser debido?
Allen should a machine power flush always be carried out before installing one of these?
Yes, No, Well maybe, Depends. It actually depends how bad the heating system is. The system needs to be clean. ua-cam.com/video/3VcMnZEbrpg/v-deo.html
Hiya Allen, I’ve just watched your video on plastic pipe with great interest, where did you get the stepped deburing tool ?
www.beneathheat.co.uk/
Can’t figure out why Viessmann 100w will stop burner and pump before zones reach 72 degrees.Aquastat and zone valves ok. Thermostats all ok.
Might have been range rated.
Hi Allen what is the spanner icon on control panel my veissmann 100 it is showing red thanks
Not sure what you mean?
Great vid Allen 👍
Thank You👍
Any issues with these if condensate freezes? How would PRV then discharge?
is the capacity of the condensate pump suitable to drain the flow if the prv is brought into operation.
Customer had left the filling loop open on this and it managed fine. Thanks.
Can the Veissmann be piped up from the rear Alan so the pipework runs up the back of the boiler rather than down ?
Hi Paul. Thank you for the question, Unfortunately not, You would need to buy a standoff bracket. Thanks.
@@AllenHart999 are they expensive Alan do you know and could I build a timber frame faced with 18mm ply to create the gap instead? Or is that not allowed? Thanks in advance.
@@AllenHart999 Thanks Allen, sorry for my previous mispell.
Is the viessmans a german make? If so how easy would it be to get parts this boiler.
Would you say its safer to go with Baxi, a british brand?
Im having boiler man coming today to give me a quote.
max navsa I wouldn’t buy British anything anymore. The constant cost cutting has resulted in poor quality products. Germans are leading everything.
Personally i'd buy british and support british manufacturing. we still make some good products.
Lots of good british stuff. Baxi platinum has been one of the best boilers i have installed over the years.
Hi Alan, does ther vitodens 050 got cooper pipe inside? And modulation pump.
050 has rubber hoses.
Hi Allen, how come viessmann can incorporate there p.r.v with the condensate drain? Don't other manufacturers have to have a visible p.r.v discharge or at least a tundish?
No idea really. You would of thought others would do it now 👍
Much easier 👍
Hello Allen. Thanks for the vids. Which is better for reliability Vogue or this one ? Also the difference is about £400 between the two.
Thanks Paul.M
Derbyshire.
Hi Paul. Honestly I do not know the answer to the question. Both very good boilers. Thanks
I live in a two bedroon bungalow one bathroom one kitchen would the 26kw be good enough flow rate for shower and 6 rads?
Yes and yes
Thx for the quick reply, off to buy one now.
Hey Allen, do you know what year the older Vitodens 100 WB1C was introduced??
Thanks
No sorry.
steowong The now older model WB1C came in during 2012 and it was used right up until the later B1kc Which is the one with the touchscreen display and copper hoses
Hi Allen would you recommend a vaillant ecotec pro combi boiler over a viessmann vitodents 050-W or even vitodents 100-W?
I would go for a Viessmann 100 out of them. Thanks.
@@AllenHart999 Hi Allen just a quick question. Do you have to get your boiler serviced by a plumber accredited by the manufacturer of your boiler in order for your warranty to be valid. I.e if I got a vaillant or viessmann boiler will I have to get it serviced by plumbers accredited by them in order for my warranty to be valid. Many thanks in return.
@@saminaali675 You could you anyone who is gas safe and has boilers, I would advise you to use someone approved though if you don,t know anyone. Thanks.
Hi Allen, how do I turn the pressure on? Greetings from Dublin
ua-cam.com/video/9v9YXRXe3sk/v-deo.html
Is the install easy ? As easy as a vogue ? Are you an Viessmann installer ? Planing to do the manufacturer course in October is it worse it?
Philippe Yon I have installed most manufacturers over the years. Viessmann doesn’t need a blow off so maybe a little easier, Both very good boilers though.
Allen Hart the control panel seen to be straight forward . Great video again , thanks , very helpful and informative.
@@7dayplumbingservices195 Thank you..
I’ve been looking at Viessmann Heatpumps and have to say they seem a step ahead of anything else.
I have never seen a Viessmann heat pump. Maybe one day 👍Thanks for watching.
Allen Hart didn’t even know they made them lol but I was looking around at what’s available, came up with the known ones like Mitsubishi Ecodan, hitachi therma v, samsung etc then came across Viessmann one and everything seemed better on it, just seemed one step ahead in many respects and I guess that’s typical of the expectation in regards to German engineering.
And looking at the video you have just done, the rubber hoses didn’t seem like a good idea, still not too keen on plastics lol but that’s more my personal perception on plastic for what it is rather than proven functionality.
But certainly this new design looks pretty solid, well built and designed what with the copper pipes, stainless heat exchanger, built in PRV with combined discharge into condensate and intuitive menu design.
I haven’t purchased a heat pump yet but it’s the intention to do so, only thing is they are one of the more expensive brands... but I guess if the quality and design lives up to the name it’s worth it for reliability and how well the product performs.
Shame heat pumps are so expensive but when installed right, they are the way forward I think. Installation is a big issue though, only reason I’m considering it is because underfloor heating is being installed throughout.
I did actually look into beneath heat, ironically they are only about a mile or 2 down the road.
But they said they strictly only deal through merchants, and a few others wouldn’t give me the design to look at before committing which was important because 1 supplier came up with a design which would of had cold spots.
@@Clicksystems I would really like to know more about heat pumps. Thanks.👍
don't don't buy viessman heat pump!
it just a oem product from China , not worth the money at all.
turn to the airconditioner brands like daikin or mitsubishi for a the heat pump that worth your money.
great video .. my Roca RX 200 wireless remote TX is unhappy . how can i PAIR my workshop RX200 to the house one .
They are good boilers but from my experience do brake down mo often then for instance Vaillant. Also parts are very very expensive.
This one has a 10-year warranty. So it should be ok for a while. Thanks.
@@AllenHart999 * Only if fitted by a Viessmann approved installer.
@@AmirKhan-qx2lr You also need to pay extra to update it to 10 years. 👍
I have the older one, I wondered do they need to be serviced?
Absolutely, Every year really. Thanks.
Hi Allen can you set timers on this boiler? For example would I be able to set it up so the heating turns on at 6am?
Just wanted to say this was a great video! Really helpful
Hey Allen, another great video. Do you see any smart boilers? Like smart appliances?
Remote control,, data, etc.
Thanks!
Not really just yet. Smart controls maybe. Thanks.
@@AllenHart999 Thanks, would be great to diagnose problems, system status, adjustments on a smartphone. Maybe someday!
@@baypos I feel that is the way we are going. What boiler do you have?
Hi Allen what's the difference between the viessmann vitodents 050-W and the 100-W? Is thier only a slight difference or if there a big difference? I know a boiler with the least amount of plastic inside is ideal. Does the 050-W have more plastic? And do they both contain stainless heat exchanger. Thank you very much in advance.
The biggest difference is the 050 has rubber pipes and the 100 has copper, I have never installed an 050 so i am not that clued up on them. Thanks. Happy new year.
@@AllenHart999 isn't thier an option to buy replacement copper pipes from them to replace the rubber hoses with? Thanks in return.
Sophie Anderson , it’s the same plastic as used in cars ,doesn’t give any issues just as the rubber hoses
It’s all down to system cleanliness Sophie
Looks like a good unit
Thank You
Hi Allen can you do video on how to setup a thermostat on a vitoden 050
I do not really install the 050 but i will if i get chance. Thanks.
Hello Alan, Very informative video on the improved boiler. My installer (I'm writing from Italy) has proposed a Viessmann combi 100-W 26kw. I was unaware that Viessmann had updated the 100-W. Is there a difference in the numeration so I could distinguish between the old and new models?
New 2021 version of 100-W combi, is designated at B1KF , you can download the installation manual from the Viessmann UK web site
Hi Allen, great video. I have the older model Vitodens 100-W WB1C, it is currently set up with a hot water cylinder but on a recent service the gas engineer said it could/should have been set up for on demand hot water. Now our hot water cylinder is leaking and I'm wondering could I get someone in to remove my old cylinder and have on demand hot water straight from the boiler? Not that I doubted him but a second opinion is always welcome! Thanks
Peter your boiler has been set up on a 4 pipe system that supplies the cylinder as well, You can revert it to a standard Combination boiler where it will be water on demand, Hope this helps
Hi Allan Can I request you to make a video on ViCare thermostat please!
Sen mükemmel bir ustasın Allen
What controls are you using with this and do you fine it easy wiring it into the viessmann i've only fitted a couple a 200 and a 222f and used the manufactures controls but they are quite expensive
oliver smith very very good question. You can use any 3rd Party controls with the 100 range. Personally I like fitting nest thermostats when possible
Hi Allen, thanks for the great review :)
How many hours should it take a plumber to fit this model, as a straight swap for a broken boiler of similar specification?
Also, is a Viessmann "standard 1m flue kit" at around £80 also definitely required when changing from an already-existing 30kW broken combi boiler?
Thanks and all the best
Depends what is required really, I would always go and look at a job and see what’s needed. Thanks.
@@AllenHart999
Hi Allen, thanks for the reply, a plumber has had a look already and has said it's a simple swap, how many hours would you estimate do you think? More like 4 hours or more like 8 hours, as that is the range of time I've read for exchanging a boiler. 1 man, who has a lot of experience. Thanks
@@avolpe734 Not possible to do correctly in 4 hours in my opinion, Take longer than that to flush. Thanks.
@@AllenHart999
The installer is not planning on flushing the system, despite me mentioning it. He said that would be "an extra £400" for a power flush, on top of the £500 quoted for installation. Does that seem worrying to you? (Green liquid is leaking out of 2 upstairs radiators too). The current broken boiler was last cleaned in 2013 I believe, and it was installed in 2011. It recently broke with error code E160 fan/fan PCB error. Many thanks
@@AllenHart999
PS. Current radiators are 33 years old
Thanks Allen I've been a worcester installer for about 10 years but recently I've found out that they are a large share holder of boxt so my loyalty as completely gone and I'm not keen on the idea of promoting worcester anymore....i was thinking of switching over to viessmann instead, do you think that would be a good move for my business? Many thanks Dan.
Daniel Angel Absolutely, Very nice boilers
@@AllenHart999 cheers Allen i actually serviced a viessmann system boiler today and what a joy it was to work on, stripped down burner etc in 5 minutes and best of all no cut knuckles....lol
Daniel Angel I switched over 10 years ago Daniel and I’ve never looked back I’m happy ,the customers are happy with the performance impressive gas savings and reliability but of course only if serviced properly
What's the issue with Boxt if you don't me asking? I'm shopping for a boiler right now. Will probably go with a veissmann.
Is it only me who finds touch screens retrograde. I serviced a ten year old Viessman ( heat only) this morning. To get it to max and min you just twiddle the right hand control ..dead easy. At ten years old it looked like new, but did need a PCB two years ago. Beware also Viessman do not use GC numbers so to identify the right spares make sure you have the boiler serial number handy. That nails the right bits.
Tim Hancock I’ve serviced quite a few as well and just out of curiosity I had a friend check the PCB board and the only fault on it was a capacitor which had failed you may want to bear this in mind as they’re only about £2or £3 to repair!
Would you recommend Viessmann over Vailant?
I don’t install Vaillant boilers, The Viessmann 100 is a very nice boiler 👍
The rubber hoses are fine, had never seen them fail, even really shoddy ones. However plastics do fail, common issue (still not fixed in latest ones) plastic part in pump block un-glues itself, thus making pump not pump, good news is that if it fails, it fails in warranty period in first year. (so far have replaced 3 of those in 1 year). Also expansion vessels are garbage (but hey, witch low end boiler doesn't), if you have option, then it is advised to install regular home depot expansion vessel parallel to system, a lot cheaper to replace and better quality. Another new issue that seems to be appearing lately is ignition/ionization electrode cable failure, again, if it fails it fails withing warranty period. Most (if not all problems) come from users who fill their system with water full of calcium and iron.
About boiler in general, good value boiler, stainless steel really does the job, it also supports all non freezing heating liquids (unlike bosch al+si heat exchangers that need additional heat exchanger to run system on anything other than water.) It's pretty much perfect to run heated floors. Outside temperature regulation is garbage for most systems, it is very hard to adjust it to perfection. If you want proper control, ether buy some old school room controller or use viessman ''open therm 2'' expansion, there you can adjust heating curve a lot better.
Thanks for the comments. Happy new year.
Thank you for your interesting comment you put up for us I just wanted to ask you which country you are in ?i as here in the UK it is very uncommon with most people and heating engineers, but I generally run many of my viessmann boilers on a diluted antifreeze solution , the boilers seem to run betterQuieter I’ve also noticed that heating efficiency improves as I assume the antifreeze solution is easier to heat up , it most certainly circulate a lot easier and quieter. what are your thoughts on running these on antifreeze? Also with the solution the rubber hoses on the flow and return do not seem to get sludged up at all. I understand from viessmann technical they are designed to run on antifreeze.
@@SalimKhan-gk1fh Im from Latvia. As I mentioned viessman supports most heating liquids but Bosch/Junkers/Buderus heat exchangers do not. While it's rare here that people run antifreeze/elfaterm/other heating liquids those who do have mixed results. Primary issue is that most technicians dont carry pump with them at all times and the liquid is messy if your boiler is installed in kitchen. Regarding efficiency Its quite opposite, bit less efficient and sometimes boiler has to conpensate inertia (water has higher heat energy capacity than any other liquid, thats why yours heats "faster" with special with antifreeze). Benefit of course is lack of calcium and other minerals in system.
@@bobsempires Greetings to latvia from UK my friend, I hope you are all well and surviving this difficult year thank you for the information which is very valuable I think you are a proper engineer may be trained in viessmann boilers ? it is very difficult to get information here in UK as the heating engineers are not very interested and just use inhibitors on every install ! Installation quality is higher across Europe, you will be surprised to know I am actually usingVolkswagen G13 antifreeze! [It’s environmentally friendly and biodegradable and not toxic] In a Viessmann 100 combination boiler I am using a approximately 5 L concentrated antifreeze in 80 L system capacity, so around 5% concentration, I am honestly finding this is working very well as I said the heating system is heating up much faster with the boiler quieter (reduction in pump circulation noise?) and gas consumption on smart meter Seems to be improved, after five years I removed the plate to plate heat exchanger and it was completely clean! The UK has big problem with engineers putting brand-new boilers onto old very dirty systems maybe you don’t have this problem in Europe? Everybody is complaining about the rubber hoses blocking in the viessmann vitodens boilers When actually they have no understanding of system water quality!!!
Very good that.
👍👍👍
Could you do a video on removing and cleaning condensation trap please?
Scott Vincent Yes it’s very easy 👍
Yes i would like to see that as well please Allen
WARNING i just had a quote from Viessman almost £400 to install a £40 sensor that takes no more than one hour to install. They have a ridiculous pricing scheme to fix things This was the minimum price they would charge to come to my house and repair the boiler. What they are really saying is WE ARE NOT INTERESTED you are on your own AVOID unless you want an endless money pit
Hi Paul. Thank you for the comment. Most manufacturers have a minimum charge of at least £300 that’s the going rate. Thanks.
Thanks that's a great video. I'm in the market for a combi as I'd like to convert from vented. Would anyone recommend an ideal vogue gen 2 over the viessman vitidens 100 ? I want the most reliable and cost effective option really. Thanks for the advice.
Both very good boilers. 👍
Thanks but if you had to choose, which one would it be ?
Akhil Varghese i would definitely go with viessmann, Miles ahead of any other boiler brands
@@SalimKhan-gk1fh thanks but do you know what the warranty is like and are parts expensive outside of warranty ?
Get yourself a Baxi , great boilers and 10 year warranty.......👍
Shall we have a look inside? 😂
Great videos Allen!
Dear Allen Hart I am a fan of watching you from Turkey. I have a question that I have a question viessman vitodens 100 26 kw. I want to adjust the gas settings of this with the gas pressure difference meter. What is the minimum and maximum mbar pressure value of this device? My house is 150 square meters. In the meantime, I have my own ways, I'm working as technical service in the city of Gaziantep in Turkey. I would appreciate if you inform from my private e-mail address. Thank you in advance, I wish you good work.
By the way my email address is serkan_kosker@hotmail.com
