What Noirot does

Noirot is a French manufacturer of electric heating appliances founded in 1933 and operating as a brand under intuis-Elec, part of Groupe intuis (formerly Groupe Muller) since 1970. The company designs, manufactures, and sells electric radiators and towel warmers for the French residential market, organized into three core technology families: inertia radiators (using cast iron, ceramic, or lava stone cores via proprietary processes including Fonte Active® and the INERFRONT system), fluid caloporteur radiators, and gentle-heat (chaleur douce) panels. Noirot operates six factories across France — including sites at Laon, Feuquières-en-Vimeu, and Fismes — with over 90% of production cost retained domestically and more than 9 of 10 radiators certified Origine France Garantie since 2012. Differentiated products include the Evolution (double-body connected radiator, Produit de l'Année 2025), Walter (compact cast-iron radiator, Produit de l'Année 2024), Radiasoft, Caldera, Tectonia, and Optiflo (100% recycled-aluminum fluid radiator), plus the connected towel warmer Actibain Connect.

The business runs a dual-channel GTM: B2C direct e-commerce via noirot.fr serving French homeowners replacing old convectors or upgrading under DPE-driven renovation pressure, and B2B via the parent group's intuis.fr/pro platform serving professional installers and tradespeople who specify Noirot in renovation and new-build projects. Distribution is augmented by physical retail (notably Leroy Merlin) and the recently expanded Enki smart-home ecosystem. Connected functionality is delivered through the intuis Connect with Netatmo gateway/app, supporting room-by-room scheduling, presence detection, consumption tracking, and voice control via Apple Home, Alexa, and Google Assistant. Revenue is generated almost entirely through one-time unit sales of radiators (€139–€729 retail) and connected accessories (€85–€100), with an after-sales spare-parts stream through the professional platform. Geographic reach is France-dominant, with historical expansion footprints into Quebec (1982) and Norway (2000s) via acquisitions.

Revenue model

1. Electric Radiator Sales (B2C): Noirot generates the majority of its revenue from direct sales of electric radiators and towel warmers to individual consumers through its e-commerce website noirot.fr. Products are priced from €139 to €729 per unit depending on model, power rating, and features. Individual consumers purchase radiators for home renovation and new construction projects.
2. Electric Radiator Sales (B2B / Professional): Sales to professional installers and tradespeople through the intuis.fr/pro B2B platform. Professionals specify Noirot radiators for renovation and new-build residential projects on behalf of end customers.
3. Connected Accessories (Gateway, Modules): Connected gateway (passerelle intuis Connect at €99.73) and wireless module accessories (€85.20 each) are sold as add-ons to compatible radiators, enabling connected functionality. These represent incremental per-installation accessory revenue on top of base radiator sales.
4. Replacement Parts and After-Sales Service: Spare parts for Noirot products are available through the intuis.fr professional platform, providing an ongoing revenue stream for replacement components such as thermostats, heating elements, and accessories.
