Radiators

What Radiators does

Radiators S.P.A. is Italy's largest manufacturer of radiators and towel warmers (scaldasalviette) for fixed heating systems, founded in 1960 in Moimacco (Udine) and operating today under two brands: DL Radiators, positioned for professional installers and demanding consumers, and De' Longhi, positioned for accessible residential heating. The product portfolio spans four heating technologies: hydraulic, electric, mixed (dual-fuel), and the proprietary E-Flow (Air Flow Technology) that integrates a towel warmer with an electric fan heater in a single unit. Manufacturing is consolidated at the Moimacco plant following a 2021 industrial reorganization, with a 16,700 sqm photovoltaic installation supplying approximately 2.3 million kWh annually. Supporting the product portfolio are the RADIATORS Connect smartphone app for remote programming and energy monitoring of connected electric radiators and towel warmers (launched November 2025), and BIM/Revit specification files distributed via the BIMobject portal for architects and engineers.

The business model is hardware sales of branded radiators, towel warmers, and accessories through a hybrid distribution model: B2B channels of wholesalers, distributors, and direct engagement with professional installers and specifiers across European markets (Italy, France, Germany confirmed), supplemented by retail channels for the De' Longhi consumer brand. Customer segments include professional installers (primary), residential consumers, healthcare/hospital facilities, and commercial/office projects, with lifetime warranty registration and certifications to ISO 9001, ISO 14001 (first in the Italian heating sector, 2006), CE marking, and EN442 standards supporting specification-driven procurement. Since 2022 the company has been subject to the direction and coordination of Stelrad Group PLC (LSE:SRAD), a UK-listed heating solutions conglomerate with market leadership in UK, Ireland, Netherlands, Belgium, and Denmark, and the entity transitioned from DL Radiators Srl to Radiators S.P.A. in June 2023.

Revenue is not publicly disclosed. End-consumer price points are not listed; products are sold exclusively through professional and retail channels with project-based consultation available via direct contact. Operating geographies span European markets with active multilingual (Italian, English, French, German) corporate communications. The company employs 101-250 staff across its Moimacco headquarters and a secondary site in Roncade (Treviso). Strategic priorities reflected in recent activity include digital specification channels (BIMobject), IoT/smart product expansion (RADIATORS Connect), and ESG positioning through renewable-powered manufacturing and circular-economy end-of-life product recovery.
