The company produces an integrated portfolio of heat pumps (Aeroblock, Biblock, Evoblock, Geoblock, Splitblock, WWP LA), gas and oil condensing boilers (Thermo Condens series including the hydrogen-ready WTC-C), industrial and commercial burners up to 17,000 kW, solar thermal collectors, and storage and hot water systems. Core technology includes proprietary multiflam combustion control achieving NOx emissions under 120 mg/kWh, and the WEM Portal web platform for remote system monitoring and management. Manufacturing is conducted in Germany and Switzerland (via subsidiary Pyropac AG), with R&D supported by approximately 100 specialists at a 5,000 sqm facility in Schwendi.

The company sells primarily through a network of certified trade partners (Heizungsfachbetriebe) in Germany, supplemented by 20 company-owned branches that handle direct sales and service for complex projects. International distribution is managed through 10 subsidiaries with representation in 50+ countries. End customers span single-family and multi-family residential, commercial and industrial facilities, and public institutions; the company holds the position of world market leader in burner technology. The Weishaupt Group generated approximately €860 million in 2024 revenue and employs over 4,400 people across the broader group, which also includes Neuberger Geb\u00e4udeautomation (building automation) and BauGrund S\u00fcd (geothermal drilling services) as wholly-owned subsidiaries.

Revenue is generated through hardware sales of heating systems, recurring service and maintenance contracts, and professional services for geothermal drilling and installation. The company is fully family-owned, currently led by Siegfried Weishaupt (Chairman of the Board) and Thomas Weishaupt, with Prof. Dr. Rainer K\u00f6gel as Supervisory Board Chairman. Recent strategic emphasis has been on expanding the heat pump portfolio with natural refrigerant R290 products and preparing the gas side of the portfolio for 100% hydrogen compatibility, positioning the company for the European building heating transition.
