HERZ Energietechnik

What HERZ Energietechnik does

HERZ Energietechnik GmbH is an Austrian manufacturer of renewable energy heating systems headquartered in Pinkafeld, Burgenland. The company designs, produces, and sells biomass boilers (wood gasification, pellet, wood chip/pellet combination) ranging from 10 kW residential units to the 2000 kW BioFire Taurus for industrial and district heating applications, with cascade configurations reaching up to 6000 kW. It also manufactures heat pumps across groundwater, ground source, air source, and domestic hot water variants, complemented by supporting modules including storage and transport systems, electrostatic precipitators, flue gas condensers, intelligent control systems, and the myHERZ internet portal for remote monitoring.

The company serves three primary customer segments: single and multi-family residential, commercial and industrial facilities, and large-scale settlement/district heating projects. Its technology stack includes a condensing pellet boiler achieving up to 106% efficiency, Smart Grid Ready heat pumps with 60°C flow temperatures for renovation projects, automatic combustion control via lambda probes, and an in-house heat pump test center for product validation. HERZ runs a 2022-expanded 18,000 m² production facility, employs 200+ people at Pinkafeld, and maintains a research partnership with FH Burgenland.

Commercially, HERZ operates a hybrid channel model: dedicated regional managers (Gebietsleiter) for Austria and Germany provide direct enterprise sales, while a global network of distribution partners (Termosun in Spain/Portugal, SB Thermique/Iseli in Switzerland/France, CleanBurn and Votab in Sweden, Alternative Heat in Ireland, Rural Energy in UK/Scotland, Verdo in Denmark, Solarbiox in Finland, Heatplus in the Netherlands, and others) handles international markets. Pricing is project-based through certified installers; the entity holds ISO 9001, Austrian Environmental Label, EHPA Quality Seal, and BAFA/GET certifications that enable subsidy-driven demand capture. The business is a subsidiary of the HERZ Group, a 50-company diversified building technology conglomerate with 40 production sites across 12 European countries, which transferred ownership to a charitable foundation in 2025.
