As part of its comprehensive range, Viessmann also offers a wide selection of tailor made services. These services include courses run by the Viessmann Academy, which provides a comprehensive training and further development programme for heating contractors, design engineers, architects, property developers, flue gas inspectors and technical education facilities, as well as its own employees. This enables the company to meet the ever increasing need for advanced training among its trade partners, arising from the structural changes in the heating equipment sector. These changes are a result of the move towards efficiency technologies and sustainable energy systems and the associated expansion of the technological spectrum. World-wide, 92,000 specialists attend the training events provided by the Viessmann Academy every year.

The Viessmann range of services also includes assistance given by its Technical Service department, a demand-oriented range of software, support through advertising and sales promotions, as well as a user friendly information and ordering system available 24/7 via the internet.

Energy and specialised forums

Prominent energy and climate experts regularly attend energy and specialised forums at the Viessmann Academy to discuss issues and share experiences. Since the first event in 2008, around 2500 trade partners – heating contractors as well as design engineers, architects and engineers – have taken part. This shows there is a real need for factual information and explanation in the context of policy and technology.

At the events, renowned experts from politics, science and the heating technology industry share their opinions, put forward possible solutions and hold Q&A sessions.

Viessmann Allendorf Foundation: commitment to responsibility

Viessmann is committed to fulfilling its environmental and social responsibilities. In accordance with this company principle, the company supports the sciences, arts, culture and society. To subsidise projects in Germany and at an international level, six-figure donations are made every year.

The Viessmann Allendorf Foundation was established in order to put these diverse commitments into a uniform framework and to secure their future continuity. In August 2010, Dr Walter Lübcke, chief executive of the administrative district where Viessmann has its head office, passed the deed of foundation on to Dr Martin Viessmann.
