About Viessmann – A global family business

We are one family and think in generations

Viessmann is a global family business. Shaped by the Viessmann family of entrepreneurs, Viessmann thrives off the multifaceted talents of our members. We have grown considerably since Johann Viessmann founded the company in 1917, and we are proud to have shared in that journey here in North America since 1978. Today, the Viessmann Group has about 12,750 employees worldwide.

Viessmann is one of the leading international manufacturers of heating, industrial and refrigeration systems. We have a strong international outlook, maintaining 22 production companies in 12 countries, subsidiaries and representatives in 74 countries, and 120 sales offices around the world.

For four generations, Viessmann has been providing comfortable, efficient and environmentally responsible heating solutions, tailored to the needs of the market. With ongoing research and development and a focus on product innovation, Viessmann has pioneered technologies that have continuously set standards and made the company into a technological innovator and pacesetter of the entire industry.
