The core division is Max Weishaupt GmbH, which is located in the southwest German town of Schwendi and includes the Group's own Research and Development Institute.
Since 2009, the business, which was founded in 1932, has been structured as a holding for three companies operating in the fields of energy technology, energy recovery, and energy management.

Energy Technology: Weishaupt offers an extensive range of products, with burners as well as complete heating systems, from gas and oil-fired condensing boilers through to solar heating systems and heat pumps that make use of renewable energy sources.

Energy Recovery: BauGrund Süd, which has been part of the Weishaupt Group since 2009, undertakes geothermal probe and well-drilling projects for heat pump installations. It also carries out site investigations and subsoil surveys. BauGrund Süd has around 40 highly professional drill gangs and, with the valuable experience of having drilled over 3 million metres, is one of Europe's leading near-surface geothermal businesses.

Energy Management: Neuberger building automation has been part of the Weishaupt Group since 1995, supplying intelligent building management systems. These systems provide efficient and cost-effective solutions that connect all of the technical systems in a building, such as heating, air conditioning, ventilation, lighting, sunscreening, and all kinds of security systems.
