“Terribly overpriced and overrated boiler. We’ve had ours for six years and it has now failed 21 times. Many/most components have been replaced over the past several winters and so far this winter it has not failed, but we do not trust it.”

“Had a Viessmann boiler fitted 5 years ago in that time it broke down once and was fixed under guarantee no problem. I do get it serviced by an approved engineer once a year and that is the answer . Would not hesitate buying another .”

Helpful Report

“Terrible durability and Poor User Experience I regret purchasing the Viessmann boiler due to its unreliable app connectivity and overall frustrating usage. The app is supposed to offer convenient control, but it rarely works as expected. Constant disconnections, errors when trying to adjust settings, and an unintuitive interface make it nearly impossible to use. Even when the app does connect, there’s a significant delay in response from the boiler. Additionally, the boiler itself is overly complicated to operate. Simple tasks like adjusting temperature or setting schedules feel like a chore, and the system isn’t user-friendly at all. For such an expensive product, I expected much better performance and functionality. I would not recommend this to anyone looking for a hassle-free heating solution.”

“State Of the art expensive combi boiler fitted 4 yrs ago trouble free until now - no central heating. 2 weeks waiting for the Valve replacement part, can't get them from Germany, only one in stock in UK... .Apparently our plumber has 3 similar systems with broken valves. But these systems are massively over complicated, a complex touch screen for the boiler control designed by a boffin for other boffin Gen Z's.... when all you want is an on/off and manual over-ride, not a NASA cockpit.”

Helpful Report

“We purchased a Viessman boiler in 2021 under the expectation they are a decent brand. Unfortunately 2 out of 3 annual services have resulted in the same part braking when the front cover was removed. Leaving us with no hot water or heating for a week each time, as the part doesn't seem to be stocked as standard in any of the main plumbing supply merchants. Viessman customer service is also very snotty, not very understanding and wipe their hands of any responsibility. Even when the boiler was installed, the installer was unable to complete the install on his first or second attempt. It took 2 other engineers to finally get it running! Would not recommend anyone to buy this brand due to the issues we've had.”

“Hi my boiler was fitted on 1/05/2024 boiler takes ages for water to get to sink downstairs water meter spinning around costs rising, when water arrives average heat, bathroom takes ages to obtain hot water anyway put bath on took ages as per normal, sadly house radiators started to get warm , contractor called engineer diverter valve replaced,sadly water still takes ages to get to sink downstairs and luke warm then goes cold, bath takes ages to get warm and boiler is in bathroom water is warm in bath only time I got hot water was through normal shower attachment, engineer coming out this week customer services said must make you aware could be a callout fee £144.00 I said it's the boiler which is at fault not anything else crazy , I would like to know we're I stand of either them replacing boiler with a new boiler or refund myself of £2500 and leave the bloody boiler and I will replace boiler with a decent one .I've owned many houses and had many new boilers which worked perfect . Probably have to take this company to court”

“I have experienced extreme difficulty getting the free Service offered for five years with my new Boiler. The Company is impossible to get through to without long waits or constantly ringing back.. First service date given was cancelled due to apparent sickness of the engineer and another appointment was made. When nobody turned up, I called to be told there was no record of such an appointment. I would have to make another one which turned out to be two weeks later. I’m extremely unimpressed with customer support for this company and would suggest to anyone looking to renew their boiler to seriously consider buying elsewhere.”

Helpful Report

“The back up service is dreadful. If you ring and they are busy , no call back is offered. Instead they cut you off and ask you to call back later. Also they have 7 email addresses. I received a message from them and was given the option of ringing, or sending an email to reply. I replied using email. I received a message to say this email address did not exist. I wanted to request that the engineer brought a thermostat with him. I am 73 years old and have been unable to shower or use my central heating for 5 days. Tomorrow (the 6th day) they are due to fix it.”

“Don't. Get a proper boiler. So.many issues with it not reading the temp.. randomly turns on and you can't shut it off with app even when u set the temp low. Only way is on the boiler itself. The app is stupidity designed . No boost button . Once u change the temp for little heat it changes the setting of program. Typical German idiotic”

“After all the chaos with different local and insurance engineers stating my boiler was beyond economical repair, I phoned Viessmann to book a one off service/repair. An engineer called Danny turned up, who was like a breath of fresh air, he knew all there was too know, he instantly diagnosed the problem and went through the boiler with a fine tooth comb cleaning it all and explaining what should be done every service and what hadn't been done previously. The boiler is now working without any problems and was advised that as my boileris only 7 years old should last 20 to 25 years if serviced correctly. The customer service is fantastic and Danny was polite, courteous and very professional. Can highly recommend both Viessmann and Danny”

“I am happy with my boiler but I tried to get, via email an answer to my query but as I cannot find a GG code I couldnt get an answer. My question was: why was my heating on at 3 am when the timer was turned off. It was Spring and warm weather. The thermostat shoed 23 deg getting warmer.”

“Great product but very low customer service, if you are looking for customer service when something goes wrong with the product do not go close to Viessmann. as a contractor, very, very disappointed.”

Helpful Report

“New flagship model Viessmann 222 boiler installed in August 2023. Nov 2023 it developed a fault and required the installer to replace the pump. Apr 2024 another fault left with no hot water or heating. Although connected to the internet from the point of install, it seems there's a totally separate process required to get the "warranty". So instead we have the standard manufacturers warranty... But this is where it's extraordinary - that warranty they claim is from the point which the merchant first had it in stock !!! Not when we bought it, or installed it !! And guess what, that stock date was just outside 2 years !! So we have no warranty at all, for a boiler that's less than 8 months old. Welcome to Viessmann. Appallingly unreliable products. Appalling service. You simply couldn't make it up.”

“We purchased a Viessmann 100-W heat pump because the company had a good reputation for service. So far we have been sorely disappointed. The unit was installed months ago, by a partner company called Energy Solutions here in Prague. We puchased the most expensive warrant for 10 years. A technician was supposed to contact us to explain how the unit works and do some fine tunning. It never happened. Two weekends ago, the unit stopped producing hot water. With no indication of a malfunction. We spent a weekend with cold water. On Monday, a nice person from Viessmann came. It was the technician who supposed to the final installation months ago. So he did that and tried to fix the problem even if he was not from the same part of the company. After four hours the machine was working again but he did not tell us what was wrong. The following Friday, the machine failed again. We call the same person, but he was on vaccation, and said that we should call the help line. We called Friday evening. We called Saturday Morning We called Saturday Lunch We called Sunday Morning We called Sunday Evening We called Monday Morning No one answered. We called the general number, the person there said to e-mail. We emailed. We called again, the lady said we will call you back and solve it today. Nothing. We received an email to schedule an appointment four days later. We called again, they said email. We called again, they said we were about to call you. Which was patently false as were calling 1 minute after closing time. They said we will solve it soon. As I write still no hot water. I can understand that sometimes a company has trouble. But I dislike communication that is not honest with the customer. I will post this widely and update as things progress.”

“Viessmann Vitodens 050 installed September 2020. To date I have replaced the expansion vessel and the pump at my own expense. The heat exchanger has now failed. I would reccomend avoiding these boilers at all costs. Very poor build quality and not fit for purpose.”

Helpful Report

“Just don't. Our 2.5-year-old broke down with a lockout issue and two plumbers including British Gas were unable to fix it because the parts must be on special order with 10 days delivery time. Their own support offered an appointment in weeks time. It is not acceptable with products that people rely on, during the cold months.”

“Boiler 2020 installed on a government grant due to my disabilities and the pump has now gone,I have no money to repair this and I’m classed as a vulnerable person so sat here in the freezing cold ,please phone me 07757714356 as I’m desperate!”

Helpful Report

“Had a Veissmann boiler fitted 9 years ago by one of their approved installers. Nothing but problems since … costing several hundred pounds per call out, usually annually. They will diagnose and fix some things but not the peripherals (e.g flue, cellar pump). Never got to the bottom of the problem and now considering replacing the boiler to get some peace. While the Viessmann engineer is fab, I wouldn’t touch their product again or recommend it to anyone.”

Helpful Report

“Absolutely atrocious customer service. I am a contractor currently on hold for over an hour. The last time I called the operator was an absolute ass. This company should be ashamed of their customer service, especially regarding contractors they do regular business with. It’s embarrassing honestly.”

Helpful Report

“The boiler is far too complicated, the wireless doesn't work well, the central heating takes too long to heat up , my 12 year old Vaillant gave better heat and far quicker . Really annoyed that I changed over .”
