What Haas+sohn Ofentechnik Gmbh does

Haas+sohn Ofentechnik GmbH is an Austrian family-owned manufacturer of residential heating appliances headquartered in Puch bei Hallein, Salzburg, tracing its origins to an 1854 iron foundry taken over by Wilhelm Ernst Haas Senior and Junior in Neuhoffnungshütten, Hessen. The company operates as a full-range supplier (Vollsortimenter) of wood-burning stoves, pellet stoves, water-carrying stoves, fireplace building kits, fireplace inserts, and wood-burning cookstoves/ranges, plus accessories such as the patented Energiespar-Zugregler, hydraulic modules, heat-storage magnesite blocks, and Wi-Fi modules. Products are designed, developed, and produced at the single Puch bei Hallein site, with stated thermal efficiency above 80%, EN 16510 certification (including room-air-independent variants for airtight buildings), and Ecodesign 2022 compliance across the range.

The technology base combines combustion engineering with embedded controls: the HSP 4.0 pellet platform delivers automatic room-temperature regulation, ember-bed-height monitoring, and a color touchscreen; water-carrying systems route up to ~70% of heat output (e.g., 6.8 kW of 10 kW on the HSP 6 WT RLU) into the central heating circuit; the patented Energiespar-Zugregler provides electricity-free draft regulation with claimed up to 10% heating-cost savings; and the HAAS+SOHN App (iOS/Android, SSL-encrypted) supports local and global remote control of up to five stoves per family account. Warranties of up to 5 years/5,000 operating hours on the welded stove body are gated on app-based product registration.

Revenue is generated through hardware sales of stoves and fireplaces via a pan-European certified specialist dealer (Fachhändler) network covering 15+ countries (DACH plus France, Benelux, Italy, Poland, Czechia, Slovakia, Hungary, Slovenia, Croatia, BiH), supplemented by a direct online spare parts shop (shop.haassohn.com) with 4,000+ permanently stocked articles and a B2B dealer login. The primary customer segments are individual homeowners seeking premium residential heating and the certified dealer/install/service channel; a secondary segment is central-heating operators integrating stoves as supplementary heating. Pricing is not publicly disclosed; quotes are issued by dealers. The company is led by Managing Directors Andrea Szamosi and Maximilian Reischl and operates with no disclosed parent, institutional investors, subsidiaries, M&A, or funding rounds.
