Weishaupt

What Weishaupt does

Weishaupt (Max Weishaupt SE) is a privately-held, family-owned German heating technology group founded in 1932 and headquartered in Schwendi, Germany, with 4,400+ group employees organized into three divisions: Energie-Technik (heating systems under the Weishaupt brand), Energie-Gewinnung (geothermal drilling via BauGrund Süd), and Energie-Management (building automation via Neuberger). The company manufactures a comprehensive portfolio of burners (residential through 17,000 kW industrial, including Ultra-LowNOx models down to 7 ppm), gas and oil condensing systems under the Thermo Condens brand (with several units certified for 100% hydrogen operation), heat pumps across the Biblock, Aeroblock, Evoblock, Splitblock, Geoblock, and WWP LA sub-brands using R290 natural refrigerant, flat-plate solar collectors (WTS-F series), and modular storage systems. Core proprietary technologies include the CleanVario self-calibrating combustion control, the WEP (Weishaupt Elektronik Plattform) control unit developed by Neuberger, the BlueFin evaporator, and the WEM Portal for remote monitoring and energy management.

The business model is hardware-led with an emerging services layer. Primary revenue comes from manufacturing and selling heating equipment, distributed exclusively through a network of certified specialist trade partners (Fachbetriebe) and supported by Weishaupt's own regional branches (Niederlassungen) for direct enterprise engagement. Pricing is not publicly disclosed and is determined per system configuration through the trade partner channel. A recurring-revenue motion is being built around the WEM Portal (web and mobile remote monitoring, included free for 5 years with heat pump purchases), service and maintenance through authorized partners, and the Weishaupt cascade control product for multi-unit heat pump arrays. Customer segments span residential (single and multi-family), commercial (hotels, universities, offices, public buildings), and industrial/large-scale (breweries, district heating, industrial process heat), with reference customers including Hotel Roomreich, Zeppelin Universität Friedrichshafen, Wohnanlage Mühlacker, Residenzschloss Arolsen, and the Westnetz H2HoWi hydrogen pilot. Geographically, Weishaupt is concentrated in the DACH region with selected global project exports.

Core offering

Weishaupt manufactures and sells heating equipment including heat pumps (air/water, brine/water, and split systems), gas and oil condensing boilers, industrial burners, and solar thermal collectors. Products are sold exclusively through a certified network of specialist trade partners (Fachbetriebe) who handle planning, installation, and service. The group also offers geothermal drilling services through BauGrund Süd and building automation through Neuberger.

Product overview

Weishaupt is a heating technology group offering a comprehensive, multi-product portfolio centered on heating, cooling, and renewable energy systems. The core offering spans five product families: (1) burners (burners for gas, oil, and dual-fuel from small residential to 17,000 kW industrial scale, including Ultra-LowNOx models); (2) gas and oil condensing systems under the Thermo Condens® brand (WTC-GW/C wall-mounted, WTC-GB floor-standing, 15–620 kW, with hydrogen-ready models); (3) heat pumps across multiple sub-brands — Biblock® (air/water monoblock), Splitblock®/Evoblock® (split systems), Aeroblock® (monoblock, outdoor), Geoblock® (brine/water ground-source), and WWP LA (large commercial air/water) — all increasingly using R290 natural refrigerant; (4) solar thermal collectors (WTS-F series); and (5) storage systems including the new Modularspeicher. Supporting the hardware are the WEM-Portal (remote management), the WEP electronic control platform, and the cascade control system for heat pump arrays. Within the group, Neuberger handles building automation and control technology, while BauGrund Süd provides geothermal drilling services for ground-source heat pump installations. The group employs over 4,400 people and serves residential, commercial, and industrial customers globally.

Scale indicators5 records

Recent moves7 records

Expansion highlights6 records

Direct peers

• Viessmann: Closest direct competitor in the DACH heating market — condensings boilers, heat pumps, biomass, and digital services. Now owned by Carrier following the ~$13B acquisition, giving Viessmann a global balance-sheet backing that Weishaupt lacks.
• Vaillant: Family-owned (Groupe Vaillant) DACH heating manufacturer with overlapping condensing boiler and heat pump portfolios serving the same Fachhandwerk channel; directly comparable on geographies, customer segments, and distribution model.
• NIBE Energy Systems: Swedish-listed heat pump manufacturer with strong European residential presence; competes most directly with Weishaupt's R290-based heat pump family and provides a public-market comparable for the heat pump business.
• Stiebel Eltron: German heat pump and hot water specialist competing directly against Weishaupt's Biblock/Aeroblock/Geoblock lines in residential and light commercial; comparable product mix and DACH focus.
• Buderus (Bosch Home Comfort): Bosch-owned DACH heating brand; overlapping condensing boiler, burner, and heat pump portfolio with very similar trade-channel (Fachhandwerk) sales model — a near-direct competitor to the Thermo Condens and Biblock/Aeroblock lines.
• Brötje (Bosch Home Comfort): Bosch-owned condensing boiler and heat pump brand in DACH; competes head-to-head with Weishaupt on similar power classes and installer channel, particularly in residential and small commercial segments.

Broad incumbents

• Daikin: Global HVAC and heat pump leader; while broader and more diversified, it directly competes with Weishaupt in commercial heat pumps (WWP LA comparable) and is setting the competitive scale benchmark for the category.
• Bosch Home Comfort (formerly Bosch Thermotechnik): Incumbent across boilers, heat pumps, and burners via Buderus, Junkers, Brötje, and Wolf brands — overlapping products across the full Weishaupt portfolio, with significantly larger R&D and global reach as part of Bosch.
• Carrier (post-Viessmann): Acquired Viessmann in 2024 to build a European heating franchise; combines Carrier's global HVAC scale with Viessmann's DACH heat pump and condensing portfolio, positioning it as a step-change larger competitor to Weishaupt's home market.
• Mitsubishi Electric: Major global HVAC and heat pump incumbent with a strong European Ecodan presence; competes in residential and commercial heat pump categories where Weishaupt is investing most.
