What Thermador does

Thermador SAS is a French wholesale distributor of heating, plumbing, and sanitary components, founded in 1968 by Guy Vincent and headquartered in Saint-Quentin-Fallavier. The company operates as a subsidiary within Thermador Groupe, a publicly listed diversified conglomerate created in 1987 to enable the stock-market listing of Thermador and its initial sister subsidiaries (Jetly, Sferaco, Dipra). Thermador serves the entirety of the French professional wholesale market, distributing approximately 4,600 product references across 50 product ranges (heating, solar thermal, biomass, heat-pump accessories, plumbing fittings, sanitary fixtures, and spare parts) sourced primarily from Italian and German manufacturers via long-standing partnerships (Caleffi since 1970, Goetze and Zilmet since 1971, DAB Pumps since 1988).

The company does not manufacture its core catalog — it curates, distributes, and supports a comprehensive multi-brand portfolio that includes a proprietary sub-brand, Thewa (sanitary fixtures, integrated in 2014), and a pre-equipped mixing bottle (B-CROSS) developed with Caleffi. Operations are supported by a 10,000m² warehouse site, 98% service rate, and 24-48h delivery across France. In 2022, the company launched both an e-commerce website surfacing 4,000+ references and the Virtual Thermador House pedagogical platform, alongside ongoing e-learning and training programs for installers.

Thermador's go-to-market is exclusively B2B through professional wholesale distributors serving plumbers, heating engineers, and sanitary installers working in individual residential housing, collective housing, tertiary/commercial buildings, and public receiving establishments (ERP). Revenue is generated via per-unit product sales (e.g., thermostatic mixers from €114, decorative radiators from €278.04) with pricing exposed on the public website for indicative purposes; transactions occur through the wholesale partner channel rather than direct consumer sales. The company is currently certified under ISO 9001:2015 (2023) and holds an EcoVadis Gold Medal (2026) with a score of 85/100 placing it in the top 5% of evaluated companies.
