Dear Andrew
Thank you so much for the great feedback regarding the boiler and installation.
Best regards
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?

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
Friendly, proficient and quality service coupled with an excellent product.

Thank you William for your great review.
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.

Colin thank you for your amazing feedback.
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.

Andrew thank you for your wonderful review.
I am very satisfied with the quality of the Viessmann boiler, however, I am less than satisfied with the installation done by their Contractor/Sub-Contractor. It was my intention to have the boiler fitted in my garage but I was strongly advised against this "due to the presence of electrical installations". As a result, the boiler was installed in my kitchen, resulting in a kitchen wall unit destroyed, broken tiles, exposed pipework, exposed plasterwork, other damage and reduction in sink draining board area. Opinions given by other tradesmen suggest that garage installation was not a problem, especially if a site survey had been undertaken before commencement of work.

Dear Sandra,

Thank you for your feedback and I am sorry to hear you are not happy with the installation you received from your chosen heating engineer.

As the installation company are not a direct employee of Viessmann, I would advise going straight to them with any issues or complaints yo have as they would be best to respond and help.

Best Regards,
Good quality product, no issues.

My new boiler is excellent & I have a lovely warm home 24/7. Very quiet too, no more pipes clicking & strange whooshing noises!

Thank you for your amazing review Susan.
The installation of the boiler took 7 weeks from start to finish after many missed appointments. The installer also failed to install correctly causing water to flood through the light sockets in the bathroom ceiling. It was a very traumatising experience. Also the manual for the thermostat is very unclear and I still have not managed to set it correctly. Very very upset and unhappy about the service.
