What DRU Fires does
DRU Fires is a Dutch-founded manufacturer of gas, electric, wood and bioethanol heating appliances, with roots in a 1754 Ulft ironworks and a UK distribution subsidiary (Drugasar Ltd, Manchester) operating since 1975 and wholly owned since 2003. The company is currently a subsidiary of the German Spartherm Group and positions itself as one of Europe's largest producers of contemporary fires and gas wall heaters, holding the Hofleverancier designation as Supplier to the Royal Dutch Court. Its core technology is gas heating differentiated by three flue architectures: balanced flue (Art, Horizon, Style and Diamond series, 2-11 kW, up to 78-85% efficiency, no electrical supply required), powered flue (Kamara series, 7-16 kW, over 90% efficiency with 15-minute warm-up), and conventional flue (S-Line and Pigalle series, now discontinued but parts-supported). DRU claims to have invented the balanced flue system in the 1930s and supplies Ceramet-coated heat exchangers with extended warranties.
The business model is a hardware sales motion executed exclusively through a national network of GAS SAFE registered heating installers across UK mainland, who handle surveys, installation, warranty and servicing; pricing is not publicly disclosed and is set at the dealer level. Primary customer segments are vertical-driven and include historic and modern churches (its most established use case), independent and state schools, offices and industrial premises, military installations (including via Landmarc on MOD estates), and residential extensions and conservatories. Marketing is primarily content-led through drugasar.com and drufire.com plus organic social channels, supported by case studies and a separate technical downloads portal (druservice.co.uk) that underpins an aftermarket parts and service ecosystem. The firmographic record lists 1-10 employees, consistent with a lean UK distribution entity within the larger Spartherm group.
