“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.”

“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.”

“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.”

“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.”

“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.”

“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 .”

“A terrible fraud company who forces customers into saying something to cancel the warranties and bully them into giving information customers don't know. Viessmann UK is complete fraud and con and think carefully before buying this product. I am now in the process of taking them up on the consumer law but it is complete waste of time to have to deal with these complete uneducated morons there, specially an agent called Amanda or something is at the front line of campaign to strip customers of the 10 year warranties that is promised them at the time of purchase. Be Very carful before you buy Viessmann UK”

“The boiler is compact, well documented and quiet in ooeration. I have switched to a Viessman approved engineer for maintenance and value his expertise and the direct access to the Viessman techical support network.”

“This system was installed 18 months ago and has packed up. Little to no support from manufacturers, an attempt to charge me £350 to repair without even knowing what the fault or issue is. Would avoid and opt for a more reputable brand!”

“Very pleased with the high tech product . It meets all my requirements. The only downside is the lack of both general expertise and high tech ability in the general heating engineering profession to be able to readily provide a truly competent sales and after-sales service. Viessmann online service very good as long as you know the question to ask. Hence the 4star review ,otherwise it would be 5star”

Hi Alison Apologies, it looks like there was a mixup when the installation company entered your details into the warranty registration portal. We can see by referencing your email address provided for the warranty details that your first name was entered incorrectly. Please accept our apologies for the confusion. Kind regards Viessmann

“As a product it is very good and I have no issues, where I do have an issue is the so called approved installers, in my opinion very unprofessional installation was very poor and had to be called out a few times to put things right”

“I highly recommend Viessmann products. They are great and the build quality is excellent. I had a new Viessmann boiler installed recently in my house in Canterbury. and a complete replacement of radiators. The local Kent company Guscott Heating could not have been more efficient and professional.”
