What Weishaupt does

Weishaupt (legally Max Weishaupt SE) is a privately held, family-owned German heating technology manufacturer founded in 1932 by Max Weishaupt in Schwendi, Baden-Württemberg. The company designs, manufactures, and distributes gas and oil-fired burners, condensing boilers, heat pumps, solar collectors, and building automation systems, serving residential, commercial, industrial, and marine/offshore customer segments globally through 4,400+ employees and subsidiaries across Europe, the Americas, and Asia.

The company's technical differentiation rests on proprietary combustion engineering, including the patented multiflam internal flue gas recirculation system, the SCOT combustion optimization system, Premix Low-NOx (PLN) burners achieving below 10 ppm NOx emissions, and microprocessor-based Digital Combustion Management controllers. Product ranges span from compact residential burners (43–2,390 MBTU/h) to industrial-scale WK-series burners up to 109,000 MBTU/h, with specialized marine-execution variants. The Weishaupt Group also operates two specialized subsidiaries—Neuberger Gebaudeautomation GmbH (building automation) and BauGrund Sud (geothermal drilling with 20,500+ sites and 3 million metres drilled).

Weishaupt generates revenue primarily through hardware sales of heating equipment complemented by service, maintenance, and training for trade customers. Distribution combines 20 direct branch offices in Germany, wholly-owned international subsidiaries, and an authorized heating contractor dealer network. The GTM motion is enterprise field sales targeting commercial, industrial, and residential customers. Pricing is not publicly disclosed and requires direct consultation. The company remains family-controlled by Siegfried and Thomas Weishaupt (sons of the founder), with no venture capital or institutional outside investment indicated.
