Thank you for your review Garner, glad you are happy with the performance of the Viessmann boiler.
Nice and quiet boiler, easy controle system economical with condensing operation. Very good installation. Just a pity gas is so expensive at the moment. But relieved I changed for my previous 40 year old boiler in summer.

We could not ask for more James, 5* is the best and we do appreciate the review.
Boiler installed by Konak. Working well but waiting for gas bill!!

Thanks Tom, we do appreciate your review and wish you well with your Viessmann boiler.
The boiler works well and is very quiet. The only slight issue was getting the guarantee extension organised; that took several emails to get actioned. The installer is known to us from way back, and has made several enquiries in the few months since the installation as to how it's all working - excellent customer service.

Thank you for the review Geoffrey, apologies for the delay in the extended warranty but see you have it all in place now. Customer Service will be glad about your feedback on there department as well.
I cannot get through on the phone or by email boiler less than 2 years old was shocked as not working when installed less than two years
Helpful Report
Unfortunately after just a few months my new Viessmann combi boiler lost hot water, with the usual trepidation when phoning a company I was shocked when answered immediately by a super helpful person who booked an engineer who appeared as promised. Was given a time slot 3 days after reporting fault, in these dark customer service times it was a joy. Hats off to them.

Thank you for the review Angela, always good to hear customers are happy with the Viessmann boiler.
Boiler works fine so far, would like a definite on/off switch on controller.
Helpful Report
Glad all is working well. Your are welcome to call our Technical team on 01952 675070 to discuss the on/off situation.
Initial customer experience was abysmal, I had to hound the installer to contact the viesmann rep in order to get the boiler registered in the 30 day period to qualify for the 12 year guarantee

Thank you for the feedback and hope you are enjoying your Viessmann boiler.
Very happy with the heating system fitted. Apart from the water being slightly too hot, I have no complaints. Good to be warm in this freezing weather!

Thank you for the review Pamela, regarding the hot water, you are able to reduce the temperature. Please feel free to contact our Technical Team on 0192 675070 and they will advise how you can achieve this.
Viessmann were recommended to me, which is a good start, but since installation completion in June 2022 we have experienced 3 issues with the boiler, installed in a letted residence, 2 of which have required an engineer to attend. It's only 6 months down the line, so it's a good job the warranty is for 10 years I guess.
Helpful Report
Very pathetic customer service. Half the radiators in my house do not work since the upgrade. The installation company continues to avoid fixing the problem. I would definitely advise going for another brand to avoid the hassle.
Helpful Report
Great boiler, super quiet with a nice app to control the setting and see the usage, I will definitely recommend it.

Dear Russ The Aftersales team can be contacted via: Telephone - 01952 675060 Email - aftersales-uk@viessmann.com Kind regards Viessmann
Installation went well. Operating system easy and working well over first 4 months. Recently we have noticed hot water taking longer to come through with the shower experiencing a dip in temperature for around 10 seconds then a return to ambient temperature. Perhaps something to consider on first year service?

Hi Neil, glad you are happy with the install, regarding the temperature issue, bring this up with the service engineer or call the After Sales on 01952 675060.
Very professional.

Thank you for you review Dauba, glad you were happy with everything.
Absolutely depressing to say the good brand name of Vissmann do NOT match their appliance and certainly the customer service. 12 days out of hot water and awaiting parts and work. No appointment for another week and more. Can not believe the heat exchanger failed twice in last 2 years with less than 8 years boiler. I have the vissmann engineer 4 times since I had it and multiple Annual cheks and services and almost changed every part. Now the heat exchanger is Split. Kept dropping pressure and now 3 weeks out of hot water and heating in this cold weather with a disability and young child at home..
Helpful Report
Dear Joe Unfortunately, without having to hand the details of your installation, we cannot comment on why your heat exchanger has split. If you would like us to look into this further, please contact: enquiries-uk@viessmann.com Kind regards Viessmann
