About IBC Heiztechnik
IBC Heiztechnik & Nostalgie Wohnprodukte is a medium-sized family business based in Sondershausen (Thuringia) and a manufacturer of cast-iron boilers as well as nostalgic cast-iron radiators. The product range includes wood gasification boilers (IBC GK-7K öko, 24.5/30/36 kW), pellet heating boilers (IBC GK-8K öko, 13/22/32 kW), buffer tanks, solar thermal packages, chimney systems and installation accessories. The boilers are manufactured according to the cast-iron sectional principle: the cast iron for boiler sections and radiator sections is cast in cooperation with the WESO Aurorahütte foundry in Gladenbach; final assembly of the sectional cast-iron boilers takes place in Sondershausen. The cast-iron radiators are offered as models CLASSICO, FLOREAL, RETRO and DK Classic in any desired number of sections. In addition to manufacturing, IBC offers individual heating consultation, KfW funding support, telephone support, remote maintenance and nationwide shipping. The company continues the tradition of the Harzer Werke, where radiators and boilers made of cast iron have been produced since 1909.
