What Heitzmann AG does

Heitzmann AG is a Swiss family-owned industrial heating company founded in 1904 and now in its fifth generation of ownership, specializing in the development, distribution, installation, and servicing of wood-fired heating systems across Switzerland. The company's core technology portfolio spans the full wood heating category: pellet boilers, log wood (Stückholz) boilers, wood chip (Hackschnitzel) boilers, combination hybrid systems, industrial-scale systems, mobile container-format heating units, and external heating modules. Heitzmann develops and manufactures its own log wood heating systems in-house while serving as the exclusive Swiss distributor for Austrian manufacturer Hargassner's pellet, wood chip, and industrial product lines. The technology stack includes automatic ignition, buffer storage (Pufferspeicher) heat accumulation, heat exchanger systems, and combustion optimization designed to meet Swiss OPair air quality standards without fine-dust filters at standard capacities.

The company generates revenue through three integrated streams: hardware sales of complete heating systems, professional services covering installation, commissioning (Inbetriebnahme), maintenance, and 7-day/24-hour customer support, and bundled planning and consulting delivered through a network of regional advisers and an in-house Verkauf-Innendienst project management team. Customers range from individual single-family homeowners (the primary segment) to multi-family housing, agricultural operations, hotels and gastronomy, commercial and industrial facilities, public buildings, sawmills/joiners, and district heating networks (Wärmeverbund), with the Wärmeverbund Schachen serving as a flagship reference project. Go-to-market is sales-led and consulting-driven, supported by a website featuring an online heating calculator and quote request form, a physical Holzenergie-Zentrum demonstration facility, regional trade fair participation, and a certified installer partner network across both German-speaking (Schachen LU headquarters) and French-speaking (Roche VD subsidiary Heitzmann SA) Switzerland. Pricing is project-based and not publicly disclosed, reflecting the customized nature of each installation.

Revenue model

1. Wood heating system equipment sales: Heitzmann generates revenue primarily from the sale of wood heating equipment including pellet boilers, log wood boilers, wood chip boilers, combination systems, industrial heating systems, mobile heating units, heating modules, and accessories. Products include both Hargassner-sourced systems and Heitzmann's own developed and manufactured log wood heating systems. The sales process involves project management from order to commissioning.
2. Installation, commissioning, and maintenance services: Revenue is generated through professional services including system installation, commissioning (Inbetriebnahme), maintenance and servicing (Wartung und Unterhalt), and technical support. The company offers 7-day/24-hour customer service and support. Schulungen (training) for installers, planners, and chimney sweeps are also offered as a service.
3. Planning and consulting services: Heitzmann provides technical consulting, concept development, and planning services for heating projects, as well as sales advice through its network of advisors. This is bundled with equipment sales for a comprehensive solutions offering.

Broad incumbents

• Bosch Thermotechnik: Bosch's heating and hot water division offering a wide portfolio of heating systems including wood, gas, oil, and heat pumps. A broad incumbent competing for the same Swiss residential and commercial heating customers with overlapping wood-burning product lines.
• Hoval: Liechtenstein-based manufacturer of heating and climate solutions with a strong Swiss market presence. Offers wood, gas, oil, and heat pump systems and competes with Heitzmann particularly in commercial and industrial-scale heating projects.
• Weishaupt: German manufacturer of burners, heating systems, and industrial heat technology with Swiss distribution. Competitor in the industrial and commercial heating segment where Heitzmann sells Hargassner-sourced industrial systems.
• Viessmann: German manufacturer of comprehensive heating, industrial, and refrigeration systems including wood-burning solutions. Operates broadly across all heating technologies in Switzerland and competes with Heitzmann on wood heating while also offering the heat pump alternative that threatens Heitzmann's market.

Direct peers

• Fröling: Austrian manufacturer of wood chip, pellet, and log wood heating systems with a strong presence in Switzerland through independent distributors. Directly competes with Heitzmann in the same wood heating product categories and competes with Heitzmann's exclusive Hargassner partnership for Swiss shelf-space.
• ETA Heiztechnik: Austrian manufacturer of wood chip, pellet, and log wood boilers with established Swiss market presence. Competes directly with Heitzmann across residential and commercial wood heating segments, including combined heating solutions.
• ÖkoFEN: European specialist in fully automatic pellet heating systems with active distribution in Switzerland. Directly competes with Heitzmann in the pellet boiler segment where Heitzmann relies on Hargassner-sourced product.
• Windhager: Austrian wood heating specialist offering pellet, wood chip, and log wood boilers distributed across Switzerland. Closely comparable product range to Heitzmann's portfolio and competes for the same Swiss installer and end-customer relationships.

Others

• Hargassner: Austrian manufacturer of pellet, wood chip, and industrial heating systems and Heitzmann's exclusive Swiss distribution partner. Not a direct competitor in Switzerland but a strategic peer in product category, technology, and business model for valuation benchmarking.
• Stiebel Eltron: German manufacturer of heat pumps and renewable heating technology with significant Swiss market presence. Not a direct wood heating peer but a key competing technology for the same residential and commercial heating customer that Heitzmann targets, and a primary beneficiary of the heat pump substitution trend.
