VIADRUS

What VIADRUS does

VIADRUS a.s. is a Czech public limited company headquartered in Bohumín, Czech Republic, historically engaged in the design and manufacture of cast iron heating equipment. Its product portfolio encompassed solid fuel boilers (HERCULES series, VIADRUS A and U22 lines, LIGNATOR, WOODPELL, VULCANUS, EKORET, HEFAISTOS), gas boilers (G27 through G700 range, GARDE, GRAND, CLAUDIUS, K4/K5, VIAKON, NAOS), cast iron radiators (Kalor, Kalor3, Termo Bohemia, Bohemia R, Styl, Atena, Windsor), accumulation tanks (AkuComfort, AkuEconomy, AkuCombi), CLIMATIX control systems, water heaters, and Regusol solar thermal systems. Core technology centered on gray iron foundry casting and boiler assembly, with control integration handled through third-party systems including Siemens LMS and CLIMATIX.

In May 2021, VIADRUS closed its gray iron foundry and related boiler and radiator manufacturing operations, exiting hardware production entirely. The company now operates exclusively as a post-sale service organization, coordinating a network of 19 authorized external service centers across all Czech Republic regions. These centers handle spare parts distribution, consulting, warranty and post-warranty service, and authorized boiler inspections under Czech Air Protection Act No. 201/2012. VIADRUS publishes and maintains the official registry of qualified inspectors authorized to certify its equipment, which constitutes its primary ongoing strategic asset.

The current business model is service- and spare-parts-driven rather than transaction-based. VIADRUS does not sell directly, does not operate e-commerce, and discloses no public pricing; spare parts and service costs are determined by individual service centers. Revenue derives from facilitating spare parts flow through the partner network and fulfilling pre-2021 warranty obligations. The customer base comprises owners and operators of legacy VIADRUS heating equipment across residential and small commercial settings in the Czech Republic, served exclusively through the 19-center authorized network.
