History

The Viessmann Group originated in Hof on the banks of the Saale, where Johann Viessmann set up a small workshop in 1917 specializing in the construction of steel boilers. In 1937 he moved operations to Allendorf (Eder) in northern Hesse. After World War II, Hans Viessmann took over his father's company and modernized it by introducing series production and industrial processes. In the 1950s and 1960s, oil replaced the previously used solid fuels, whilst steel boilers became increasingly important. Viessmann seized these growth opportunities and developed into a medium-sized industrial enterprise with 1,400 employees.

The 1970s were a time of expansion. In 1972, Viessmann opened its first foreign factory in Faulquemont (France), followed by Waterloo, Ontario (Canada), the first site outside Europe, in 1978. With the development of new technologies, the company responded to the challenges of the energy crisis: In 1976, the first solar collectors were produced, followed by the first heat pumps in 1978.

The fall of the Berlin Wall in 1989 opened up new markets – initially in the former East Germany and later in Eastern Europe. At the end of 1991/start of 1992, Dr. Hans Viessmann handed the company over to his son Dr. Martin Viessmann.

In the 1990s, major structural changes were taking place: from floorstanding boilers to wall mounted boilers, from oil to gas, from gas-fired boilers to condensing technology. Viessmann set up a new production facility for wall mounted gas boilers in Allendorf, whilst developing an international sales office and branch network. As of 2005, the company launched the "Efficiency Plus" campaign focusing on demonstrating energy saving and sustainable processes and reducing the company's environmental footprint, whilst also expanding the product range with the acquisition of other technologies. Viessmann first acquired wood combustion specialists Mawera and Köb, followed by KWT, a manufacturer of large heat pumps and ESS for combined heating and power systems. BIOFerm, Schmack and Carbotech acquisitions covered the area of biogas technology, and with an evacuated tube solar collectors plant in Dachang (China), the company has expanded its market presence into solar thermal systems.
