What ISAN Radiátory does
ISAN Radiátory s.r.o. is a Czech privately held limited liability company (s.r.o.) that designs and manufactures heating and cooling radiators, convectors, and ceiling panels for residential, commercial, and public-sector buildings. Founded in 1953 and headquartered in Blansko with a registered office in Brno (IČ 25334727), ISAN claims to be the largest manufacturer of bathroom tubular radiators in the Czech Republic and exports approximately 90% of its production, primarily to European Union countries. The portfolio is organized into seven main product lines — Melody (80+ design and bathroom radiator models), Atol (column/sectional radiators), Spiral (finned tube radiators), Termo (24V DC low-voltage floor convectors), Exact (radiant convectors with massive 70x11mm steel profiles), Ecolite (lamellar heat-exchanger convectors), and Sofito (ceiling radiant panels) — supported by electric regulators and heating rods (including WiFi-enabled Nexus series), electric drying sets, thermostatic connection sets, and custom-printed radiators. Manufacturing is anchored in steel fabrication technologies including capillary welding and resistance welding, with EPD environmental certifications and ISO 9001/14001/50001 compliance.
The company sells exclusively through a channel-partner model, distributing via more than 486 dealer partners across the Czech Republic and Slovakia, including bathroom studios, building material chains (e.g., Stavebniny DEK, PTÁČEK, SIKO), and specialized heating wholesalers (e.g., RICHTER + FRENZEL, GIENGER). Customer acquisition is supported by three online product configurators (Melody, Atol, Termo), trade show presence (ISH Frankfurt), downloadable technical documentation, and a dedicated sales team (e.g., Radek Čihák, David Pavláček for Czech Republic; Rastislav Volek for Slovakia). Pricing is quote-based through dealers and not publicly disclosed; the underlying revenue mechanic is hardware sales to B2B resellers and developers, with named enterprise reference customers in hospitality (Hotel Gala Praha), real estate development (Quadrat, Aura, Ikaria, Viviena residential complexes), public buildings (CEITEC Brno, Churchill Square Praha), and heritage renovation (Automatické mlýny Pardubice). Recurring revenue exposure is limited; the model is essentially project-driven industrial goods distribution rather than SaaS or subscription.
