Having installed Viessmann boilers for well over 15 years, I can fully endorse them as boilers of superior quality and technology over other brands. The interface and build quality are superb and the heat exchanger, in my opinion, is the …

Have been installing Viessmann boilers for around 18 months now and the quality is very good. They are a brilliant modern boiler which have easy solutions to make the boiler run efficiently. The backup could be slightly better ( i am lucky …

We had a Viessmann VItodens 111 boiler that had so many problems, these German boilers are supposed to be so good but waiting on parts can take several days. Their engineer visit under the warranty is sometimes hopeless, I’ve been left …

I’ve had my Viessmann boiler for two years now, and to date it hasn’t missed a beat. Significantly quieter than the prematurely expired boiler (another brand) that it replaced.

Impossible to book a service to comply with the warranty conditions. UK after care is in meltdown it seems. There’s no option on the phone line to book a service anymore, you have to fill in an online form and wait for them to contact you. …

Viessmann are the best boiler manufacturers in Europe. If it’s gas boilers or heat pumps they have a solution to any situation. I had a boiler in a basement and Viessmann made me a vertical flue that fitted inside the existing chimney. It’s proper engineering and extremely reliable

My fitting people left with no hot water working. They said the brand new boiler has a faulty component and need me to contact customer service myself. Viessmann’s line is always busy and I cannot get hold of anyone.

Don’t be fooled by associating the German name with reliability. I have had problem after problem with my boiler (and so have my parents). The customer service is utterly dreadful. I would change boilers just on the basis of the customer service if I could afford to.

As an installer I have fitted many different boilers , viessmann boilers are by far the best out there, google stainless steel vs aluminium heat exchangers and you see stainless steel performs and last longer than aluminium . Viessmann after care is also great for customers piece of mind.

Biggest mistake ever to go for a viessmann boiler, I paid extra money for an extended warranty. I been trying to contact them for a few weeks over the phone and email but no response, I noticed that must of the customers who try to contact them have the same issue.
