What Reka does
REKA A/S (legal name Maskinfabrikken REKA A/S) is a Danish family-owned manufacturer of biomass-fired heating systems, founded in 1979 and headquartered in Aars, Denmark. The company designs and builds boilers and complementary fuel-handling equipment that burn wood pellets, wood chips, straw, and mixed biomass, addressing customers seeking fossil-fuel alternatives for residential, commercial, and light-industrial heating.
Its core product lineup spans the HKRST series (20/30/60 kW dry-fuel boilers and 100-3500 mixed-biomass boilers) featuring compact moving step grates that prevent slag formation, the TPK 12/22 kW wood-pellet boilers with integrated hoppers, and the HK Manual straw-fired boilers of which more than 14,000 units have been sold. Supporting components include multi-size hoppers with chain and auger outfeeders, a slow-rotating Chaff Cutter (HFA-approved for in-storage placement), a Hardox-built Straw Pusher for Hesston big bales, corten-steel chimneys, and cyclone dust-removal units. The technical differentiator is a fire-tube boiler construction insulated with A-batts and clad in aluminum zinc/plastisol steel plates for durability.
REKA operates an indirect go-to-market model, selling exclusively through a global dealer network that handles local sales, installation, and service. Revenue is generated from one-time hardware sales of boilers and complementary modules; pricing is not publicly disclosed and quotes are issued on request. The company employs 11-50 staff, is privately held with no external investors identified, and supports customers in Denmark and internationally through dedicated sales, quotation, and foreign-sales functions.
