Viessmann who are they. Never heard of them until I needed a new combination boiler. I did my research and Viessmann were top of the list in consumer tests. I have been extremely pleased with the quality and efficiency of my Viessman boiler which is also very quiet. First class product.
Helpful Report
Very good service, turned up on time, cleaned up after and the workers were very polite.
Helpful Report
Boiler stopped working one day after installation. There was subsequently poor co-ordination between installation company and Viessmann, with each blaming each other. Two Viessman engineers inspected boiler, identified fault and provided replacement part but refused to install or fix. I was left without working boiler for nearly a week after installation. Issues like this should be handled behind closed doors - customers should not have to mediate between companies.

Dear Graham Our records show that we attended the property in June to fix a wiring issue. If you have any further feedback regarding the situation described please send it to so it can be looked into. Many thanks Viessmann
Installation was very good - the operation has been excellent so far - as a family e are a high % user - and the bills we get are normally high - we feel that this has made our usage more efficient.

My boiler has broken down twice in the three years since installation. After the last so called repair the hot water keeps going cold and even at the hottest I can still keep my had under the running tap. Shower is also affected.

Hi, sorry to hear you've experienced issues with the boilers. If your boiler is still under warranty you can book a callout so Viessmann's engineers can diagnose the issue. Please call 01952 675060 to speak to Aftersales. Alternatively you can contact the Technical department for insight into how to fix the issue: 01952 675070 Kind regards Viessmann
8 years ago, we had a brand new Viessmann Vitodens 100-W system boiler for our central heating only. It went wrong within days and we had the plumber back fixing it 4-5 times over the first couple of months of having been in. After that, we had the plumber round at least twice a year, often more, with various faults and it never managed to heat the house properly even when working as it should. Eventually, we got tired of having such a useless boiler and had a new Vitodens 200-W system boiler installed just over a year ago. Not the combi, the commercial grade system boiler, only to run the central heating. Hot water has always been provided by the Aga (which has been working faultlessly throughout). I wish I had insisted on a different brand after years of suffering the 100-W. The new boiler started flashing a fault after less than 2 months. Bearing in mind it had been installed in the middle of the summer, this was its first actual use. It was fine on the first couple of days, but then came up with a fault. We had the plumber back more often than having hot meals with yet more fault codes flashing and the boiler not working. It spent most of the lockdown flashing fault codes, even through the summer. It hasn't worked for more than half an hour at a time for nearly 8 months. Bearing in mind it's only about 15 months old, that's pretty useless. I'm never ever having another Viessmann product for as long as I live. First one was bad enough and needed scrapping after just 7 years and the new one is even worse.

Hi Please could you email with your contact details so we can look into this for you asap? Kind regards Viessmann
We have a Viessmann boiler which we have had faultless service from over the last 10 years. I simply can’t fault it. It’s been brilliant.

New Boiler started off to flying start. Now second time without hot water. So frustrating! Filters fitted to H2O supply system drained flushed x4 times problem persists.

Hi We are sorry to hear this. Please could you provide your full address and contact details so we can look into this for you? Many thanks Viessmann
Very disappointed in the overall fitting of my boiler. I bought the boiler to replace a 15+ year old boiler and after have the new one fitted I wished I stuck with the old. The mess left by the fitter; large crumbling hole in the kitchen wall (that my dad had to fill/plaster) is still crumbling onto my kitchen worktop, a myriad of pipes (that the old boiler never had) taking up large amounts of room in my already small kitchen, random pipe that is not attached to anything just left poking out of the kitchen work top and finally the noise it makes every so often is loud enough to be heard upstairs. For the considerably amount of money spent in the system I am sorely disappointed and local tradesmen who have been in and seen the result (plumber and electrician) are shocked at the quality of the work.

so far appears to be a good boiler. well installed by proficient engineers. The temp controller does need a bit of understanding, but once mastered is good. had mine finally commissioned January 2019, with 10-year guiarantee

Dear Andrew Thank you so much for the great feedback regarding the boiler and installation. Best regards Viessmann
i am looking to install a new combi boiler and am in the process of researching the various options. something i find worrying here is the corporate stock reply from veissman to poor reviews. clearly there's a problem with the control system being unfit for purpose but no solution is offered. just how many bad reviews does a company need to have before they take the appropriate action to fix the problem? these are clearly good efficient boilers but i'm not prepared to take the risk of having a control system i am unable to operate. has the control system been greatly simplified on the latest domestic models? furthermore, people are talking of a 10 year guarantee but, from what i have read, this seems to have been reduced to seven years in the uk. is this the case and if so why?

Hi, Thank you for taking the time to write your review. The control system has been updated on the Vitodens 200-W and all other domestic gas boilers in our range comes with documentation on how to work the control system. Alternatively, there is information provided on our website if needed. The 10 year extended warranty is offered across our Vitodens 100-W and 200-W range as long as the boiler has been installed by a Viessmann trained installer. The Vitodens 050-W comes with a 7 year extended warranty unless the installer you have selected has contract support from ourselves and can therefore offer a 10 year extended warranty. I hope this information helps and if you need any further assistance, please do not hesitate to get back in contact. Kind Regards, Your Viessmann Team email:
Friendly, proficient and quality service coupled with an excellent product.

Still early days yet, but so far, the boiler works well, is simple to operate (as is the wireless heating controller) and provides plenty of warmth to our home.

Boiler works well with no problems, it’s one of those items in the home it’s when it doesn’t that’s when you notice it being there, So fingers crossed we have no issues.

Thank you Rebecca for your great review.
The advice I received from Viessmann before buying was sound, and the recommended installer was great, being able to solve all the problems of our system to retrofit a Vitodens 111, which has been trouble free since installation in September 2019.
