Viessmann Gas Boiler Maintanence

I was trying to make an appointment (neither the radiators nor hot water is working and there is a baby at home) with Viessmann due to having error code `F4`, however the earliest date possible was in 3 months. It is unnecessarily long, definitely not going to replace my new gas boiler with Viessmann. Poor after sales service, not recommended.

Never again

Dear viessmann, I'm currently already 3 weeks without hot water or heating in my appartement. 3 different plumbers tried replacing various parts but the boiler always broke down again. As adviced by one of the plumbers, I called viessmann for technical expertise exactly one week ago. After 1,5 hours in a waiting queue, I got through, only to hear that if I don't have a maintenance contract directly with them I should contact them via a plumber. No problem for me if that's company policy. So next step was that I had a plumber contact viessmann. Their answer to the plumber was that they would call me for a visit of one of their technicians. That was 7 days ago. I did not receive any call yet. Another plumber I contacted then ordered a replacement relay from viessmann after his inspection of our boiler, but he received the wrong one. He told viessmann it's the wrong one but they continue arguing it's the right one and if it isn't we should just replace the whole system for 3.500 euro. Our boiler is only 7 years old. We will now replace the whole system but definitely not with a viessmann, since I don't want to risk anymore having to go through so much trouble and costs to fulfill basic needs as hot water and heating in a cold winter month.
Having had contact with so many different plumbers has taught me that a viessmann boiler normally is good quality, but more complex to repair when they break down than one from another brand. And with such unreliable customer service, impossible to fix rapidly when in need. If you're having doubt about your next boiler, hope you make the right choice and go for another brand.

No care for the client whatsoever

This is the worst experience I have ever had. I am waiting since over three weeks to have my heating system fixed. With neither hot water nor heating I have been on the phone with my expert and Viessmann every day. Every week they keep informing me they will solve the problem by the end of the week. Come Friday everything gets pushed to next week and the circus restarts.

With a three-months old baby and being in February we start trying to understand if there is another way to fix the situation. We meet with enormous resistance and rudeness from the teams at Viessmann (both Belgian and German branches). After 3 weeks of waiting we - by ourselves and talking to other experts - figure out they have ordered a piece that does not exist anymore and neither Viessmann nor our experts figured this out. Had it been for the brilliant (ironic) efforts of Viessmann we would wait another three weeks before they figure out our problem.

Main takeaway: DO NOT BUY VIESSMANN the systems break and their terrible service will leave you without heat and hot water when you need it the most!

We are sorry to hear that you are experiencing poor service from Viessmann. Due to the late start of the heating season this year, it is difficult for our technical department to deal with all requests quickly. Our apologies for this.
