Passat Energy

What Passat Energy does

Passat Energy ApS is a Danish manufacturer of biofuel boilers and solid-fuel heating systems, headquartered in Ørum, Denmark. Founded in 1958 as Ørum Maskinfabrik, the company pivoted to bioenergy in 1971 following the oil crisis and has since become one of the established Danish biofuel boiler brands, reporting cumulative sales of 70,000 combustion plants over 25 years. Its core product portfolio spans gasification boilers (Ventum series, 20–100 kW), fully automatic wood pellet boilers (Caria series, 12–150 kW), multi-fuel biomass boilers (Compact series, 11–199 kW, produced since 1991), semi-automatic pellet boilers (Eco Mini, 12–60 kW), fully automatic wood chip boilers (Powerchip, 20–100 kW), and industrial-grade HO boilers (140–990 kW). Underlying technology emphasizes high-efficiency combustion (up to 93% on the Caria series) via microprocessor-controlled oxygen sensing, PLC-based touch-screen automation, automatic ash removal, and modulating operation, all manufactured to EU EN 303-5 (2013) Class 5 emission standards.

The company's business model is a hybrid B2B/B2C industrial-equipment sale backed by recurring service and parts revenue. Boilers, tanks, silos, auger systems, and chimneys are sold through a dedicated B2B reseller shop to qualified trade installers (plumbers, blacksmiths, HVAC installers), while consumer sales are routed through parent company HH Energy ApS (hh-energy.dk). Pricing is published per unit (e.g., Caria 12 at 42,999 DKK incl. VAT, Ventum 20 at 26,499 DKK incl. VAT), with installed-base service priced at 795 DKK/hour and 24/7 emergency support across 15+ service centres in Denmark and additional centres in Sweden, Norway, Germany, and France. Customer segments split between private individuals seeking residential biomass heating (3.6–150 kW) and commercial/industrial customers requiring larger systems (140 kW–1 MW) in agriculture, hospitality, logistics, and construction — with named enterprise logos including DSV, Saint-Gobain, AAR Airport, and several Danish farms and hotels.

Revenue is generated across four streams: hardware sales (boilers, accessories), service/maintenance contracts, spare parts, and project-based solution packages (container heating plants, complete wood chip systems, straw handling plants). The company is privately held by HH Energy ApS — itself owned by two former Passat Energy employees — with no venture, growth, or private equity capital disclosed. In 2023–2024 Passat extended the franchise with the Powerchip wood chip boiler and a new Passat Compact air-to-water heat pump product line, signalling a transition beyond pure biomass into broader low-carbon heating categories.
