    Viessmann

    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.
