Viessmann

I bought a new Viessman brand air conditioner and it only cools at 18 degrees—it does not cool at any of the other levels. It is probably faulty when it left the factory, which makes me question their quality control process. Customer service does not care at all about this product. Although I have ...

Magnificent Viessmann! I’ve always preferred German products and had great trust in the Germans. I admired their work ethic and way of life. We bought a Viessmann heat pump. We used it for 2 months last year and only until February 20 this year. Today is April 11, and our heat pump still hasn’t been...

On 12.02.2025, our Viessmann boiler with serial number 7514912401447100 displayed an F5 fault, so we called the service center at 444 9092. They informed us that a service request had been created and that we would receive a call. On 13.02.2025, I contacted Çakmak Technical Services at 0212 660 07 7...

I bought a Viessmann boiler two years ago, and after only two winters of use, it’s already broken and no longer heating the radiators. The warranty expired in May 2024, just five months ago, and now the product is unusable. I’m incredibly disappointed that a new boiler from a reputable brand would ...

Purchasing a Viessmann boiler has been a regretful experience. Despite being a brand-new device, it has displayed a different error every day since we bought it just a week ago. When I contacted customer service, they told me a technician would come within three business days. Meanwhile, it’s freezi...

As with every year, my Viessmann boiler is causing issues once again. Previously, I had to replace the boiler’s control unit, and now, once again, it’s failing to heat the water. Viessmann boilers seem to consistently have problems, particularly with water heating, and this recurring issue has becom...

I bought two Viessmann air conditioners for my new home, and I regret it deeply. I waited 2.5 months for the authorized service to come and install the air conditioners. When they finally sent three people, it was clear from the start that they were inexperienced. They installed the air conditioners...

My Viessmann combi boiler's expansion tank malfunctioned for the second time, prompting the company to recommend a replacement. Due to the significant costs involved, I decided to seek a second opinion from another technician before proceeding with the repair. Upon inspection, the technician discove...

I have Vitodens 200 boiler. The copper pipe connecting boiler to pump cracked. Authorized technical service and Turkish headquarter informed me that this copper pipe is no longer in production, it is 10 years old product and reccomended to buy a new boiler. The copper pipe was welded temporarily but...

For the past few years my Viessmann air conditioner, just not giving me what it's supposed to...there were holdups in getting the air conditioner's gas tank refilled because of the pandemic. When I originally contacted their service, they said they'd be right over as soon as the gas supply problem w...

The boiler I bought only 3 months ago malfunctioned. I called the service, they came the next day and looked at it. They said that the hose inside the boiler was defective. The fact that the 3-month-old hose was punctured in such a short time is already meaningful. They said they would order and ins...

We've had our Viessmann combi boiler for almost a year, but we've had to call for service almost every month because the hot water suddenly loses pressure and temperature after 30 or 40 days, leaving us frustrated and inconvenienced. It's disheartening to have spent so much money and not gotten the ...

Greetings, After only nine months of use, our Viessmann Connect combi boiler has stopped functioning for three days. Despite my repeated calls to both the service and the main office over the course of three days, no one from either location showed up to intervene. I informed them that I am caring f...
