Heizomat

What Heizomat does

Heizomat - Gerätebau + Energiesysteme GmbH is a German manufacturer of fully automatic wood chip and biomass heating systems, headquartered in Gunzenhausen, Bavaria. Founded in 1982 by Robert Bloos and still family-owned and operated (Robert Bloos Sr. and Robert Bloos Jr. as Managing Directors), the company runs two production facilities in Bavaria — Werk Maicha (~35,000 sqm primary site housing development, chipper assembly, control cabinet construction, and a new exhibition/office building) and Werk Heidenheim (a 370-hectare former military site acquired in 2005, housing heavy manufacturing including welding, bending, and brickwork). Total headcount is reported at 330+ employees across both sites, with over 80% of components manufactured in-house.\n\nThe product portfolio centers on two wood chip boiler series: the HSK-RA (30–450 kW) for residential, agricultural, and small commercial use, and the RHK-AK (30–990 kW, extendable to 2,400 kW in multi-boiler configurations) for industrial, agricultural, hotel, and district heating applications. Core differentiators include patented technologies developed since 1982 — the Gelenkarmaustragung (jointed arm extraction), the Kettenentaschung (chain ash extraction), the Parallelführung (parallel guidance), and chain-based fuel extraction that pushes rather than rotates fuel — plus the Siemens-based HeizoControl automation family and the HeizoClean EF 185 electrostatic particle separator (up to 82% dust separation). The portfolio extends into wood chippers under the Heizohack brand (compact HM 6-300 units to self-propelled HM 14-860 machines with ~600 HP and 10m cranes), Heizotrans filling and transport systems, Heizotruck special-purpose forestry/agricultural trucks, Heizocont container/plug-and-play heating modules, the Heizomat Portal cloud-based remote monitoring service (powered by IXON Cloud), and Heizomat E-Power combined heat and power systems. The Heizostroh biomass shredder and Palettenhacker pallet chipper extend input fuels beyond wood chips to straw, waste wood, and pallets.\n\nRevenue is generated through hardware sales (boilers, chippers, transport systems, special trucks) and professional services (installation, commissioning, maintenance), with quote-based pricing on capital equipment and published prices on merchandise. Distribution combines a German dealer network (zip code-based dealer locator), dedicated regional field sales representatives covering defined territories (e.g., Mittel- & Oberfranken), and direct sales for enterprise and municipal projects (district heating networks, industrial facilities, public sector installations). Internationally, Heizomat operates through distribution partners and wholly-owned or jointly-controlled regional entities in approximately 30 countries across Europe, North and South America, Asia, Africa, and Oceania, including exclusive partner Saelen Energie for France. Customer segments span private households, agriculture, hotels and gastronomy, industry and commerce, district heating cooperatives, municipalities and public sector, and forestry and logging, with named reference customers ranging from individual families to municipal utilities and industrial operations.
