For generations to come

We create living spaces for generations to come.

104 years ago, Johann Viessmann founded a company that has become one of the world’s leading providers of climate and energy solutions, and has grown into a family of 12700 members.

We create living spaces for generations to come.

Connecting heritage and future

Over the past 100 years, change has been our constant companion. Looking back at the key milestones in the Viessmann family history, it becomes clear that enthusiasm for innovation is embedded in our DNA.

Thinking in bigger terms than we had ever dared to imagine

At home throughout the world, but firmly rooted in our native soil. In our case, that’s no contradiction!

We think in longer terms, spanning generations.

The image shows Prof. Martin and Max Viessmann in conversation.

With Max Viessmann, who joined the company in 2015, the fourth generation has taken up the reins. In his role of Co-CEO, he guides the fortunes of the global Viessmann family in tandem with Joachim Janssen. Supporting him as Chairman of the Board of Directors is his father Martin, who boasts 40 years of operative experience. In this joint interview, father and son describe how they are harnessing the strength of two generations to shape the future of the Viessmann Group.


As the owners of a family enterprise with a 12700-strong workforce, both of you have a tremendous responsibility resting on your shoulders. How are you able to cope with this pressure?

A generational change is always accompanied by a change in culture. How has this change manifested itself?

How are you communicating your messages within the company?

How can you tell if your messages are having the desired motivating effect?

Don’t you sometimes think it would be much easier to sell the company than enter into an experiment where the outcome is unclear?

In addition to developing climate and energy solutions, you are also making large-scale investments in other companies, predominantly start-ups. Are you still a medium-sized family enterprise or have you already become a kind of family investor? Or put another way: How much of its core business does Viessmann need?

Commitment to environment and society

Sustainability – maintaining a harmonious balance between economy, ecology and social responsibility – has always been a topic of great significance to us.

"During the Corona pandemic, we donated 100,000 euros to schools in the district in the form of laptops and iPads. In this way, Viessmann is helping to improve school equipment for the time after the Corona crisis and is creating virtual learning spaces for current and future generations of students," says Katharina Viessmann.

Viessmann Family Holding — Safeguarding the company’s future

We think in terms of generations, not quarters. To ensure Viessmann can remain operative for many years to come, in the 104rd year of our existence we have set a new course for the future and optimized our corporate structure.

In the 104rd year of this family-owned company, we have laid the structural foundation for generations to come by means of the new Viessmann Family Holding – augmenting our Integrated Solutions Offering as a second pillar of future success.

The Viessmann Family Holding’s Executive Council is headed by its president, Prof. Dr. Martin Viessmann. Katharina Viessmann in her role as Executive Council as well as Prof. Dr. Thomas Rödder (Flick Gocke Schaumburg) and Dr. Albert Christmann (Dr. Oetker) are also part of the body as “non-executive” members. Operationally, the Family Holding will continue to be managed by Co-CEO Maximilian Viessmann, Co-CEO Joachim Janssen and CFO Dr. Ulrich Hüllmann.

This is how we are forging a seamless link between our heritage and our future. Prof. Dr. Martin Viessmann: “As a family business, we stand for trust and reliability. For us, the focus is not on the next quarterly report, but on ensuring the continuation of the business into the generation to come. This is only possible through profitability, further growth and financial independence. Through the Family Holding, we have created the ideal foundations for attaining these objectives.”

Viessmann provides solutions for entire living spaces

Viessmann is evolving from a heating manufacturer to a solutions provider for entire living spaces – both inside and outside of buildings.

Playing a central role in this process is the new “Integrated Viessmann Solution Offering” that uses connectivity and platforms to seamlessly combine products and systems with digital services and value-added services. It unites our origins and our future within a clear structure.

Expansion of the solutions portfolio

Numerous smart people will be helping us to add new solutions to our portfolio. This includes our users of course. After all, there are few better qualified co-developers than those who will be using the solution themselves later on. Our installer partners, who are becoming more and more involved in the development of new products, will also be giving us valuable assistance.





Value Added Services


As a company, we are always close to our partners, no matter where they’re located. Our innovative climate-friendly products can be found throughout the world as well.
