“Best boilers on the domestic market ”
Written on: 29/03/2013
I've been installing Veissmann boilers for two years now and they are by far the best on the market. I previously fitted worcester bosch, but have found Veissmanns are more reliable and better made. No other manufacturer gives a 10 year guarantee on the heat exchanger. buy one now !!! (read more)

I've hAd this boiler just short of 5 years it's been a load of rubbish since the day it was installed,in just under 5 years it's had a replacement ignition switch which was to get the boiler working in the first place,18 months later a step motor ,then another 18 months on another step motor....it's now needs topping up everyday to get it to work at all...sick to death of it and don't say it has a 5 year warranty at the time I brought it it was only 3 year warranty ....that said you do expect a boiler to last longer then 5 years ...so people learn from my mistake and do not buy this boiler ..

“Veissman Vitrodens 100 System Boiler 3 years on.”
Written on: 13/03/2013
Her Majesty’s Government with their Boiler Trade in Scheme and the sneaking suspicion persuaded me to replace my perfectly functional but very inefficient (I know know) Portterton Kingfisher (Vintage 1973) with a new boiler. It was a hard decision as the Potterton worked fine and I was “used” to paying the gas bill. It was also a very simple boiler (Pump, Gas valve and Stat) so I was concerned about adding complexity. Doing my research it was clear that a stainless steel heat... (read more)

“Works well in Canada - no complaints here.”
Written on: 12/03/2013
Our Vitodens 100 with Combi-Plus gives us plenty of reliable heat and DHW, despite our cold winters. Paying for a quality installation really is the key. Our installers provided a 1-1/2" circulation loop with a low loss header, and the rads tie into this loop. The installers also created a distribution manifold that allows us to control every rad in the house from the boiler location. Given that we no longer have a hot water tank, we naturally have to wait a minute for the DHW, but once the... (read more)

TOTAL DISASTER. The boiler never worked properly due to DESIGN FAULTS which cause valves to stick. Boiler still within their 5 year warranty period yet Viessmann won't even reply.

You don't have the current Viessmann model. Infact there has been 2 more completely different models over the last 5 years that have taken over from yours.
The model you have is the first one they ever produced for the UK market, the WB1A, which had its faults. A few years later they brought out the WB1B model which is excellent and now they have just brough out the WB1C which again is outstanding.
The current boilers are way better than the competition. People want to hear reviews about the current models available.

NO.
People want to know what sort of company they are dealing with; in this case one with a history of failing to deal with complaints and failing to rectify or replace their faulty-designed boilers still within their so-called 5 year guarantee period.
AVOID.

It's not just me that's had a bad experience.
Only 43% of users here would recommend them.
They rate the boilers only two point seven out of five.
Have a breakdown and Viessmann will do everything it can to wriggle out of the Guarantee including just ignoring you and hoping you'll go away.
Installers don't get to see that side of this disgraceful company.

You install them. Customers have to live with them, and their irritating design faults.
If only 43% of customers are satisfied, I'm not the only one with a bad experience. A rating of only 2.7 out of 5 confirms this.
But worse than this is that Viessmann won't honour warranty claims when they do go wrong.

Your correct and thats why I said its a pity you have had a bad experience. I have heard others mention poor customer service also, there is no excuse for that.
If you had brought one of the last two models and had a good installer you would not have had to call Viessmann at all and you would be giving them 5 out of 5 purely based on ultra reliable well engineered systems.
Most other bad reviews are down to poor installs, infact if you look at other big boiler brands Vaillant included not any of them score above 3 out of 5. Most are dirty systems or bad customer service. Other thing to remember is most satisfied customers don't bother coming on these forums.
I wouldn't install anything else, but as you say I dont have customer experience so I can't vouch for that. All I know is if one of my customers needed a warranty visit I would be dealing with it as I tell them to call me.

Just reading your comment, reading between the line it seem that you don't have a viesmanns boiler at home if that is the case then having one installed in your home would be a better endorcement than just saying they are better, I have had a viesmann vitoden 100 for some years now and have had faults constantly for that time German Vorsprung durch technik; I dont think so.

I want to agree with you. We had a Viessmann installed and it never worked from day one. Cost us a lot of money and the Veissmann service team blamed everything but the boiler. Dirty radiator filters, lime scale, you name it. Veissmann after sales service non existent. We even took out an extra years guarantee for £190 and had them come to fix it. It broke down again the next day. They refused to come out to look at it, in spite of the guarantee.
We have now given in and bought a new boiler inspite of the Viessemann only being 33 months old. A British one which hopefully will work.

Viessmann don't claim to lead the way in technology, thats AUDI.
Like it or not Viessmann are way ahead in technology and engineering over other brands.
I am not 'just saying they are better' I have many many of them fitted out there in my local area. Trust me if any of them suddenly had no heating or hot water they would be on the phone to me immediatley. Fact is they don't, next time I see them will be on the yearly service. I have a choice to fit any boiler I want for them. Most manufactures offer very lucrative incentives to get us to fit their boilers, Viessmann don't, they don't need to. So why do I fit them? Because they don't break down if fitted professionally. Thats what I need, no breakdowns and no call backs, just satisfied customers.
Oh and to help you read between the lines, yes I do have one in my own home. Plus there are another two in my families homes. So why are these all so reliable and yours not? Think we all know why.

I've had the Vitodens 100 for 5 years now (installed in 2007). These are (as all the installers are saying) very nicely engineered boilers. However this one (early models) does have a design fault which will bite anyone who leaves it off for long periods. Also the narrow-piped, single-path heate xchanger is designed for clean water so fitting it to an old system full of rust and sludge will cause problems unless suitable care is taken.

You have obviously been very fortunate. We have the 100 and it has been a nightmare. We had it fitted in 2008 and it started causing us problems within 3 months and continues to do so, the last problem was the pump that needed to be replaced so another £300.00 up the spout!!! I am not going to list all that has gone wrong but just to say I wish I had gone with my research and gut and stuck to the WB and not been swayed by the engineer who sold and fitted this for me. Adding a utility room to the property this year so going to take the opportunity to ditch the Viessman and find something hopefully more reliable..........Update, other half just running a bath and the boiler is now struggling to deliver anywhere near the 12 litres per min it promises to do, managing just about half of that. As I said earlier, a nightmare so be warned if your in the market for a new boiler!!! Or I may have just been unfortunate and got one produced on a Friday afternoon.

We needed a new combi boiler because our old one Vailliant was running too much and too long and made the house not efficient. Also our bills were sky high. I did some research in diverse types of boilers and saw one installer giving it a good thumbs up.

Just to add a little more concerning this boiler. I forgot to mention that we also have weather compensation installed and you can really notice that it takes care of the environment temperature. Before with our vaillant we had to adjust the thermostat all the time to keep it warm when the temperature goes down. This weather compensation is taking of that automatically. It senses the outside temperature and makes the boiler work a little harder when needed, but when the ideal temperature is reached 20,5 degrees C. It shuts down and it barely comes back on again. If it does come on it will be on the lowest stage of the modulation of the boiler. Extremely quiet. This after noon I was not even sure it was burning any gas so quiet it was, but I checked the radiators and they were nice and hot. Not overly hot like old boilers so you can't put your hands on it, but a proper temperature of 60 degrees. At the moment it is 1.8 degrees C. outside. Nicely toasty inside downstairs as well upstairs. Really happy so far. The negative stories are for me unfounded.

We had the VV 100 installed thinking we were upgrading our system. Although our previous boiler was inefficient and un-modern, I'd take it back if i could. Most of the time the initial DHW from our tap takes time to run hot, and some of the time it takes a good deal of time. I can live with that (but why should I?). However, after running hot for a minute, it usually (not always) starts to blast cold water, and it takes at least three to five minutes for the hot water to (slowly)... (read more)

As a gas installer of over 20 years experience I can honestly say that Viessmann boilers are the best appliances that I have ever fitted. On average we install 100-150 boilers a year and we have had a zero call back rate since we started installing Viessmann products 2 years ago. The attention to detail is typically German in it's thoroughness and servicing is straightforward and simple. The other negative reviews are interesting but reading between the lines it is clear that the problems... (read more)

Problems always occur when a system is poorly installed by an inexperienced engineer. The QC on these systems is none less than a QC on a BMW. If you don't get your technology serviced by the right engineers within the service period you will most definately have problems before the warranty is up. Basicaly these boilers are designed to last only if you get them serviced by a qualified engineer within the service period....

Mine was fitted by an excellent registered Corgi, Viessmann fitter. He also serviced it every year on time and in full. This boiler has been a nightmare since fitted. I had to have an engineer out to it within days of fitting to change a part in it. At least once a year it breaks down. It is currently spewing water out of it. I'm guessing the expansion tank yet again! It's had loads of parts changed as they fail very quickly. One part should have been changed when fitted as it was known that it was faulty from the start apparently. Now I'm stuck in the winter with no hot water, and no heating just as the New Year is about to start. And to top it all off there is no emergency engineer team for weekends, or holidays. This company sucks.

Sorry but this boiler is rubbish. I've had mine fitted for 6 yrs and it has never run correctly since fitted. I've had to have engineers out to it every year, if not twice a year. So far it is only my anger at the fact that it has never run correctly that has meant it has been sorted for free. Otherwise it's at least £190 everytime they do anything. It's had nearly every part replaced once, if not twice. It's pure rubbish.

Soon as you install the boiler on a dirty system with out a quality filter and with out flushing you have already shortened its life greatly. Not just the heat exchanger but everything else will get lined with sludge and dirt. You are now paying price couple years later.
This would happen to any boiler, regardless of warranty. No manufacture should pick up your bill when its not installed correctly.
Almost everyone can be wrong (they are the ones cutting on cost on installation) the others are right and enjoying their new boilers and don't need to visit a review forum.
Look carefully every single negative comment refers to a dirty system.

This is all down to people always going with the cheapest deal. There are installers out there that cut corners and pull the wall over your eyes to gain maximum profit from their customers. There's nothing wrong with the Viessmann products. We are so confident with them we offer an extra years warranty on top of the manufacturers but then again we fit a Magnaclean filter and power flush every system we install 1 on. Most "Heating Engineers" don't even own a power flush machine but claim they have used one. Just be aware of what your trusted installer is doing for you.

Jezbee4's you've missed the point. I agree with you thats how the boiler should work. After power is restored to the boiler after a power cut the boiler control unit goes into a default condition and starts the heating circuit (ignoring any previous communication with the controller/room stat). I've had a Viessmann engineer out twice to replace the main boiler control unit and controller. The resolution has been to fit a third party Honeywell controller.......which defeats the object of having a Veissmann controller. I would expect much more from this product. Having to manually override the boiler control is unsafe in my mind especially if you have a pet or new born baby in the house and find your heating on in the night after a power cut. My advise, buy a Worcester Bosch

How can the Honeywell programmer be the issue, when indeed it rectified the problem. My original installation included the boiler fitted with a VEISSMANN controller, this is when the problem occurred. It doesn't matter how of these new ones you have fitted, Veissmann recognise this as an issue in certain circumstances, so be expecting calls from your customers.......

Hi, I have just spoken to Viessmann Technical Support about this issue. They have confirmed that after a power cut the Viessmann Controller will go into default mode and (potentially) fire up the central heating. However, they have told me that after 20 minutes of "initialization" self tests the Viessmann Controller will revert to the customer programmed thermostat / timer settings.
Viessmann Technical Support claim that this 20 minute self test "initialization" is necessary to ensure that the central heating system is in working order before reverting to the customer programmed settings.
Did you wait 20 minutes before manually overriding the default boiler condition? If you did wait more than 20 minutes then you are right there is a Viessmann Controller design fault. If not, then I think the Viessmann Controller is fit for purpose.

Veissmann have since contacted me and told me the same thing about the 20 minute period. I did not wait 20mins and here is why.......
When this happened at 4am, with a baby, i can not have a blast of additional heat for 20mins unless i wake up and realise whats going on to manaully override it, do you realise how dangerous this can be?
Ok, this is how the controller is designed to operate, but my point again and again, under certain conditions and circumstances this function is not ideal to me as a customer. If you're not bothered about this, then go ahead and purchase.

Fit a Viessmann weather compensation sensor (£30) then even if the boiler does remain in heating mode for a while it will only fire the correct flow temp around the radiators in accordance with the outside temp.

Without a doubt, the BEST boiler on the market. Your fault is a 99.9% chance of poor installation. When a boiler fails, it is your installer's responsibility. When he/she can confirm it's a boiler fault under warranty, then Viessmann can get involved. I assume your installer has completed the mandatory /Bench Mark Log Book' and left it with you? Have the notified Gas Safe Register of the installation? If your installer already had to amend pipe work after the installation, you can be pretty confident he is not great!

As a registered installer with over 27 years experience I can assure you that the Viessmann 100 range is one of the best boilers that I've fitted. They out perform the equivalent Worcester Bosch appliance by far and are a much better build quality. If your installer has had to "reconfigure" the pipe-work then it suggests that he didn't do it right to begin with. If you have doubts about the quality of the installation then Gas Safe will send an inspector out to check it out free of charge. It is your installer's responsibility to arrange for Viessmann to come out if he believes the product is at fault.

Ok, so you have had to call back the engineer to reconfigure the pipe work? what does that tell you? that he done it wrong in the first place!
Why don't you go on a forum and write negative comments about the installer? why blame the boiler? Its 2 weeks old so under warranty easily, if you feel its the boiler causing issues Viessmann WILL come out within a day or two, that I can guarantee, IF its installed by GAS SAFE registered company and its been registered with GAS SAFE. If non of the last two have been carried out then call GAS SAFE register who will come and inspect the installation FOC as it could be an illegal installation.
If Viessmann do not come out I will be happy to book a visit for you.
Reading your description of symptoms I am betting though this is all down to your installer.

Was the pump changed when your boiler was fitted, if it is an old pump it maybe surging to much power from the board causing strain on the board?? Board fails everybody blames the boiler.

By the way, I have worked on these units before, and always install Viessmann. PCB's will eventually need replacing on every boiler, it is common. Your boiler is complex and so will cost a little more. I purchased a PCB last year and cost around £250.00 + vat.
Let me know I can give you my merchants number.
Your boiler is actually very good, but just need to make sure its installed exactly correctly. Use an engineer who knows what he's doing.

Going by the date of your post it would appear that this is a current problem. It would seem that you have been sold a lemon here. The Eurola is not commonly sold in the UK. If it is a recent installation why would Viessmann charge you for a repair, unless it was not installed by a registered approved person, in which case it's no surprise. We install 150-200 boilers a year and the Viessmann Vitoden range are by far the best product on the market. If fitted properly, by a trained engineer Viessmann's aftercare is very good.

Hi I am a viessmann specialist, the model you have is a wb1a, this model did have a few problems, but if you have had the modifications done, and the service engineer who is looking after it knows the issues, and procedures, you should not have any problems with it from then on, as for the domestic heat exchanger blocking up it should have some scale protection on the boiler if you live in a hard water area, but more than likely it is black or red oxide from the radiators, this is poor installation or maintenance, I would suggest contacting Viessmann and getting a specialist, in your area to come and checking the boiler over, doing the modifications (treating the water in the system correctly and flushing if necessary that could be costly if done correctly using acid and a tds meter for purity of the system, very few people do this correctly please contact kamco.co.uk), then your problems will be over,

Response to guest's response:
Thanks for your comment, but Viessman came to look at the boiler about 3 weeks ago. They said it was dirt in the system, but the system has been flushed out three times (twice before they came last and again since, with acid). I don't know about modifications, but they had to replace the main board because they could not repair an ignition problem. We have a descaler and magnaclean filter attached. Viessman have basically tried to say it's nothing to do with them since around 2009 when the 2 year guarantee ran out. The main hot water heat exchanger has been cleaned out, the hot water heat exchanger replaced twice, the water in the system runs clean, and if there was a problem with the installation, that was done by an engineer they trained. In my view, they should accept the boiler had faults, that the installation - if not up to scratch - was in part their responsibility, and come and fix the issues for free, given that we have paid them for engineer visits and parts, as well as several other engineers. I'm not interested in what they have to say unless it is to offer a cost-free service. I would rather spend ten times the cost of another visit for a boiler that actually works.

In response to Dazrickards: the problem is you go with an engineer who is trained and registered with the maufacturer so you expect they will install to the standards approved by the manufacturer. The previous boiler worked without fault for 10 years after we moved here but was 25 years old and starting to leak water so we looked for a replacement. There is a descaler and a magnaclean, and the engineer said he would NOT recommend a power flush because in his opinion they can cause more problems than they fix by dislodging particles that were not a problem before the flush. If the engineering profession wants clients to take responsibility for their colleagues' weaknesses, I'll hold up my hands. But the guy was fully registered and approved by Viessman, we didn't hire a cowboy, unless even registered engineers can be cowboys, in which case where does that leave the average consumer?

Hello Salim
I appreciate your situation that you did try and use a professional. As a Viessmann installer, I personally think their 'suggested' installers should all be quality vetted. Unfortunatley gas installers can go on a Viessmann course and then be on their website. Viessmann have no idea on their quality of work. Yes their are also lots of gas installers that door very poor work, which is legal but to a very poor standard, then guys like you are left feeling robbed. Always in future get a recommendation of a good installer. For example I am on 'which local' You were let down by poor installation not by the boiler. If you brought a current Viessmann, and had a professional installation you would be very pleased with it. The Viessmann service is poor and is something I constantly am asking them to improve. Good luck!

I have read quite a few of these reviews and what seems common to me is how all these boiler problems are blamed on poor installation. The allegation seems to be coming from installers who make a living out of installing Viessman boilers. I am not just talking about people on this site as I have visited many forums trying to get a perspective as to if these boilers are good or bad. I don't believe that a bad installation would ruin a good quality boiler but would ruin the installation instead. A good quality boiler would protect itself by shutting down until the threat was removed (bad installation) and then it would be possible to reset it. In this instance as SalimSalam says it was installed by a Viessman approved engineer. The site was visited and inspected by a Viessman rep at least 5 times. If the installation was poor then they should have picked up on this and advised how this could be rectified. Viessman had a responsibility for this system as their TRAINED INSTALLER installed the boiler, I don't believe a Viessman boiler is any different to install than any other boiler, It has a flow, return, cold water feed, hot water supply same as any other boiler. There may be a difference in how the boiler is commissioned and if Viessman are not training its installers well enough to commission their boilers then they are still at fault. Personally I will go for the Worcester Bosch, I have read a few horror stories about them but only maybe about 10% of what I have heard from Viessman. They can't all be down to poor installation!!!

In response to Marcia's Dad comment. In 6 years of fitting many Viessmann's I have had no call backs to boiler faults, its that simple!
Poor installation does lead to faulty boiler (fact), otherwise there is no point in me doing a professional installation. I may aswell just take a boiler off and put new one on and away I go, job done.
Some early Viessmann's had a few simple faults a long while ago, but these were simple and once fixed they were good to go.
Having a magna clean installed and scale filter does not protect the boiler 100%.
How on earth you people expect that a clogged heat exchanger is the boilers fault is beyond me. Clogged means clogged with something, the boiler did not arive with sludge or scale in it, but good luck finding a boiler out there that has built in shut down feature that can sense when dirt is travelling back to boiler. As Marcia's Dad suggested. By the way I have replaced two main aluminium heat exchangers from two different Worcester bosch boilers this month, from blocked returns. Is this also a boiler issue? No installation issue! These were 4 year old boilers. For build quality, better design and ease of maintenance Viessmann beats all others easily. This is coming from an engineer who has fitted both, not a poorly informed consumer.

In response to Dazrickard's comments. I take it that salimsalam's did not install their own central heating system and it was done by someone who was deemed competent by Viessman. The very obvious pattern I see here is Installers cannot say a good enough word for these boilers, Customers IE end users, cannot say a bad enough word for the same boiler. Most customer complaints seem to be expansion vessels, PCB boards, Faulty Heat exchanger, Ignition, PRV and F4 flap problems and poor customer services. All Installers complaints seem to be blame the Installer not the boiler. Unless Viessman Installers are building the boilers on site I would class these as inherent defects. My present boiler is a Glowworm Swiftflow which is 16 years old, I don't consider this to be the cream of boilers but in the 16 years I have had it I have had to replace the fan and the PCB. As a novice I installed this boiler and central heating system 16 years ago without using Magnaclean or any other scale reducing device but I did add twice the amount of inhibitor. (And yes before you ask, I did get a CORGI Registered person to make the gas connection) We have been nursing this boiler along for the last 3 years and i have been looking at boilers since then. If my boiler had gone 3 years ago I would have replaced it with a Viessman boiler because Pimlico Plumbers a very reputable company in London were recommending and fitting them.(No I don't work for them after seeing a TV programme about them I admire the company's ethos) Pimlico Plumbers have stopped fitting Viessman boilers some time ago and I had been trying to find out why. It could have simply being a commercial decision on their part. If I am going to spend £1200 on a boiler I want to know it will stand up to the job. When I bought the glowworm I fully expected to have to change it within 8 to 10 years. I will not replace it with another glowworm as I don't think I will be so lucky next time. I researched the boiler I have upstairs which is now 18 years old and will last another 10 and has not missed a beat in all that time. (Potterton Profile 100e) I split my system and researched the Glowworm as a cheaper alternative to service the downstairs and that has lasted 16 years. I run two boilers as a cheaper alternative to heating 14 rooms when we are all sitting in 1 room or constantly running upstairs to turn radiators on and off. So you cannot say I have been a poorly informed customer. I do my research no matter how long it takes.

I do wish you luck on your next boiler. Viessmann or any other manufacture will not deem anyone competant, all they state is that a person has been trained on their products, how do they know how good their work is? Only 'Gas Safe' deem us competant with Gas.
I will give you a simple summary, I have installed Glow worm, Vaillant, and Worcester Bosch and now Viessmann for the 6 years. The first 3 I have had various callbacks, all relating to annoying boiler faults, usually electrical or various components inside leaking, usually within the first year. Its not good to have callbacks and not satisfying for me or my customers. I got the opportunity to go to Viessmann and train on their domestic and commercial boilers, after seeing the quality first hand started to fit these. Now since then I have had no callbacks, and I mean NONE. My installation practice has not changed so what does this tell you?
There are a 101 things that could have been done wrong by these other installers.
Old boilers will keep ticking along for a long time with dirt in system, new boilers are much more complex and efficient and won't give long service with dirt in system.
Your research is a little out of date!
F4 flap does not exist on the current Viessmann boilers. Expansion vessels are same problem on all boilers, usually need re pressurising every year,most engineers do not even check them. PCB's never fail on current models, Ignition module was faulty on models of about 6 + years ago, not anymore. Heat exchangers are by far best on market, and can't be faulty as its a lump of stainless steel. It can however be clogged from deposits. Their stainless steel heat exchangers come with 10 year warranty, and patent and pended, a very well engineered item.
Go with a Viessmann, and get a top notch installer and you will be impressed, if your not you are welcome to come back to me!
Customer service? well all I can vouch for here in East anglia / midlands its exceptional. The area rep is very good.

I have a 2010 Vitodens 100 (non-Combi) it has not missed a beat in a year and a half. It is fitted with temperature compensation (and rather lacking in science since I don’t know what the outside temperatures were) its year on year gas consumption 50% less gas than the Old Potterton Kingfisher it replaced. I chose the Viessmann over other high end boilers for it reputation of reliability provided by the large bore stainless steel heat exchanger. So far so very good! The only down side is... (read more)

Written on: 05/05/2011
I have been installing viesman vitoden 100 range for about 3 years. Lost count of how many I've installed. I use them because I fit them and forget about them. Customer service is good and they honour their 5 year warranty. All I can say is most problems are installer related, powerfushing, inadequate gas supplys and condense lines. Get a good installer who knows his job not some straight out of a 4 week plumbing coarse! You people go for the cheapest quote and expect the best! (read more)

Looks like you have been very lucky then...I had this boiler installed just over 3years ago within the 1st 3months it needed a new ignition switch September 09 it needed a new valve switch, and guess what July 11 I need another new valve switch they have as a good will gesture said they will send me another new valve switch but I will have to pay to have it installed...I would not recommend this boiler to anyone ..looks like it is going to need this switch every 18months what a load of garbage I fully expected a boiler to last more then 3years but looks like I was wrong. ..i was wondering how come you say 5years warranty ....I was told it is only 3years

2 expansion vessels, 2 PCB boards, 1 Faulty Heat exchanger, 1 Ignition, PRV and 2 call outs for a F4 = flap problem, another design fault, and thats only the one's I can remember.
You have been lucky. Nothing to do with 4 week plumbing course fitters. Mine was fitted by a Veissmann registered installer with 40 years experience, even he has had enough of this dross unit.
Nearly almost had all the bits replaced, and its still pile of garbage.
Now on the 7th year of this living nightmare, May 2012, and it has broken down again, Expansion vessel again. RUBBISH NEVER AGAIN !
My God you've been lucky with your experiences.

Hi everyone.I am installing Vitodence 100 since they came to the North American market.Piping the boiler is very important in order to keep the fan motor and controller healthy.Most plumbers don,t know how to pipe this boiler.If they make a 1 1/2 boiler loop and run the boiler pump with the boiler contactor through this loop,none of the abover problems will happen.By the way the quality of the gas is very important to keep the heat exchanger free of any blockage which cause burning the...

Hi.
Ay advise would be useful please, a friend of mine has had the vitodens 100 gas condencing boiler fitted and she a problem.
When you turn the water on upstairs in the kitchen, (Yes it is upstairs) the water pressure downstairs reduces considerably especially the bath which resorts to a trickle.
The incoming water pressure has been checked and is fine.
Any advice would be helpfull.
Thanks Craig.

Sadly I inherited this system when I bought my house in Germany. The system was brand new as the house had been fully renovated, so there should have been no calls for concern, however....it has proved to be nothing but trouble - so much for German engineering excellence.
To be fair to Viessmann they offer super energy saving potential. Install a Vitodens 100 and you will drastically reduce your gas consumption...BECAUSE IT WILL NEVER BE WORKING WHEN YOU NEED IT.
They should change their...

I don’t agree about the reliability. I have a 2010 vintage Vitodens 100 it has not missed a beat! It is fitted with temperature compensation (and rather lacking in science since I don’t know what the outside temperatures were) in its first year it burned 50% less gas than the Old Potterton Kingfisher it replaced.

I bought a Viessman Vitodends 100 boiler in 2007 and had it installed by a reputable plumber.
Since then I've experienced numerous reliability problems with this boiler and have had to get get an engineer out on three separate occasions to replace a stuck internal air flap and, most recently, to replace a faulty ignition unit. It seems there are a number of acknowledged design faults with this boiler. Viessman's customer service team are polite but inflexible and have refused to offer...

We are also Viessmann installers and find the product very good. It really depends on the quality of installer to be able adhere to all relevant regs and manufactures reccomendations to get these boilers, and any other appliance installed correctly.
We have about 25 under our belt now and at present, no break downs or call outs.We have a good relationship with the company and look forward to installing many more

I bought a Viessman Vitodens 100 Compact in September 2008 and it has been entirely satisfactory. I understand the early ones were not so good, and the newer ones are even better. It is essential to have it installed by a Viessmann-approved person, trained by them (free). There is a list on their website. That way you get the 5-year parts and labour guarantee. If you are putting it on an old heating system, you are very likely to have a lot of dirt, rust, sludge and sediment in it, and... (read more)

Thought I better reply ,we have over the last 4 years installed over 400 Viessmann boilers and can honestly say the call out rate has been remarkably low maybe 5or 6 in total .All were up and running within 24 hours .NO I DONT WORK FOR VIESSMANN and could install any boiler on the market if I wished to. If installed correctly then there should be no problems .Viessmann have given us every backup although that has not been needed often. Main problems we have had is with other badly installed boilers fitted by others so called installers who dont want to know when they play up .Viessmann quite rightly cannot accept responsibility if they are incorrectly fitted hence we get involved as we have been trained to install and repair.AS with anything in life you can get faulty ones and its normally these are the ones that people take trouble to write about.

Im wondering the same thing, I work on the railway but don't spend my time on review sites telling people how wonderful the 9.15 to Birmingham was in response to someone saying that they were stuck for 5 hours and the service is poor.
I simply cannot believe that all these installer come home after a hard days graft and get on the internet just on the off chance someone has bad mouthed the same make of boiler they have installed today!!! i can't see why an installer would even be looking at this site. It makes no sense at all. All i can say is beware of these recommendations from installer and people who say they have owned a Vissmann boiler for 5 years and it makes them tea in the morning. Again why are they on here they don't need advice on a boiler. Rant over im just off to write a review on my 9 year old dishwasher!!!

quite simple, if your an installer and you hear people giving a bad review about a product you know for a fact is very good, why wouldn't you want to add your opinion?
Sounds like you need to make up your mind and choose a boiler. If all reviews are biased and not installers why you bother coming here?

I did Dannyrichards2013, I chose and installed a Worcester Bosch Greenstar 28CDI around June last year and it has been fantastic. It heats my house up in around 15 minutes and gives me instant hot water, and when I say instant I mean from the second I turn that tap on. (I still haven't worked out how it does this)
Even though I would marry this boiler as I'm truly in love, I still have not had the urge to rush through the front door of my lovely warm house, get on the internet and profess my undying love for Worcester Bosch!!
As far as I'm concerned I paid a good price for the boiler, it preforms better than expected but that is reflected in the price. If I heard someone speaking bad of a Worcester Bosch, it wouldn't urge me to get on the internet to put the world to rights as I have no other interest in them, I don't own shares in the company I just happen to own one.
But seeing as you asked I came on here to find out about Viessmann Boilers around this time last year.
Pimlico Plumbers used to install them as their preferred choice. They have a very high standard of workmanship but stopped installing Viessmann Boilers. I asked them why they stopped installing them and got no response. In hindsight they really couldn't respond because I could have been a friend of a disgruntled customer looking for information.
my boiler was on its last legs and I originally wanted to install a Viessmann Boiler I had to find out why Pimlico Plumbers stopped using them. Now I have found out I need to look no further than a Worcester Bosch.
Of course you could be completely right, and Viessmann Boilers could be excellent boilers, but in my experience If you have a good experience with a product you will tell on average around 2 or 3 people, and only when asked. If you have a bad experience you try to tell the world, which is the case of this review page is exactly what has happened.
I just found it amusing that all installers on here rated this boiler highly, considering this is how they make their living, and all customers or end users hated the boilers They are on here to tell the world of their bad experience. If bad things happen to good people, they in turn try to stop that bad experience from happening to others.
If I am going to spend over £1000 on a boiler, why take the chance on the word of someone who installs it rather than someone who has to live with it and use it daily.

Note as an installer who could fit any make boiler ,.I spend most of my day repairing boilers of every make some good some bad ,based on my vast experience in repairing boilers I am sad to say that some of the worst that I come across are English ,Including Worcester ,most are over 5 years old and are a nightmare to work on ,parts expensive etc. The others at my company who do the installations of new boilers ,ALL of them have now fitted Viessmann boilers in their own houses as have I ,and YES we did have to pay for them at normal rate. No dont work for Viessmann but if installed correctly these boilers are one of the very best on the market.Still what do I know 48 years repairing and installing boilers???.There are other good boilers Vaillant ,Glowworm (owned by Vaillant) Vocera are all quite good.

My original question still stands. Why did a high quality and successful company like Pimiclo Plumbers stop installing Vissmann boilers? Surely it makes good commercial sense to install a boiler you don't have go back to? Even if you have to reduce your profit margin you would come out ahead on fewer return visits and improved reputation. If someone from Pimiclo plumbers would like to comment it would be appreciated, but i do suspect they won't be reading this because they will all be busy installing boilers rather than defending them.

Some of the larger companies ,smaller ones as well,use cost as their prime concern ,we also get offered better deals and yes we could make more profit , lot dont even make a visit if a boiler goes down , 9 out of 10 simply call manufactures if under warranty ,
I only came on this site because a customer said he had read bad reviews ,and I can see where he was coming from .However as with all sites of this nature probable for every 1 bad reviews there are maybe 100 who are happy with there boilers etc ,so never even think of writing . We gave this customer a long random list of our customers(all who allowed us to do this upon having their boiler installed) so he could ask any one of them their opinion of Viessmann boiler ,not sure if he followed it up but has placed an order .
Like I said there are a few other good boilers about ,but not prepared to take a gamble solely for extra profit and maybe not so happy customers ps.We are maybe like Pimiclo very busy ,I start at 6am finish at maybe 7pm but I still find time to make inquiries to help customers make the right choice and answer any questions .

Am I right that Viessmann have only been making domestic boilers for a relatively short time, so can any one give an objective view over a few years. I am thinking of replacing our Worcester combi boiler because it is proving unreliable. It is the discontinued 28 CDI RSF model and has stopped producing hot water although it still gives hot water with the central heating. I am told it is possibly the diverter valve. We have only had it for 18 years and in that time it has had the pressure vessel re-pressurised about 3 years ago. Needless to say we will be re-placing with another Worcester, the only reason is that we are not repairing is that the new condensor boilers are more efficient and can produce instant hot water. I think that with a guarantee of 5 years and a good service contract I won't worry for a while. But if I am still around I will try to follow up in another 15 years or so.

I found this review not helpful because...this review relates to the old Dover type Viessmann boiler. Unfortunately, Viessmann at this time did acknowledge that they had an issue with the diverter valve & because of that they released the new version boiler with an 'aquablock'(the parts at the bottom of the combi that direct the water) developed in conjunction with Grundfoss. On the new version, all of the parts including the heat exchanger can be relativley easily removed for inspection & cleaning, including the diverter valve. They have also patented this design which means that you are unlikely to see it on any other boler manufacturer. In 16 years they also have a zero failure rate on their patented heat exchanger as this is made from stainless steel & not aluminium like lots of other manufacturers which is why they give it a 10 year warranty. I can't speak about the service as their is no excuse for that behaviour!

Worcester-Bosch give a 10yr heat exchanger warranty on gas boilers, and 5yr warranty on oil. Also their spares are a lot cheaper than Viessman.
