What welltherm does

Welltherm GmbH is a privately held German manufacturer of electric infrared heating systems headquartered in Lüdenscheid, North Rhine-Westphalia. The company designs and produces a broad portfolio of infrared heating panels under its proprietary ESHC+ (Entire Surface Heat Conductor) technology platform, which covers more than 70% of each heating surface with heating conductors and is claimed to deliver a 74.3% radiation share and up to 30% cost savings versus competing infrared products. The product line spans glass-front heaters (Crystal, Mirror, Satino, Chalkboard, custom RAL, Picture-print), powder-coated metal heaters, BKW Plus bathroom heaters with dual space/towel-drying zones, traditional Badradiator Classic units, electric underfloor heating mats, outdoor radiant heaters (HP Klassik/Glass variants and the DAZEX-based Ilios), church pew and desk-targeted heaters, and high-temperature industrial infrared heaters. Complementary accessories include heating elements (Rondo NG, Konstant), towel holders, LED light frames, ceiling installation frames, and a bidirectional radio control system integrating wireless thermostats, receivers, sensors, actuators, and a Tydom bridge for free smartphone app control.

The business operates on a one-time hardware sale revenue model with quote-based pricing distributed through a multi-channel go-to-market that combines direct website sales and an extensive certified partner/installer network across Germany, supplemented by owned sales offices in Southern Germany and Switzerland, and partner sales points in Spain, Mallorca, Denmark, and Ireland. Primary customers are residential homeowners seeking primary or supplementary heating for new construction, KfW-efficiency houses, and renovations, with secondary verticals in churches, commercial/industrial spaces (car dealerships, industrial halls, fitness/yoga studios), outdoor hospitality (terraces, restaurants), and office workplaces. The company emphasizes German manufacturing ("Made in Germany"), holds VDE, VDE-EMC, GS, CE, RoHS, EIHA-Gütesiegel, and DIN EN ISO 9001:2015 (since 2017) certifications, and markets low-EMF ("electrosmog-arm") construction for health-conscious buyers as a differentiator.

The company is founder/management-owned with no disclosed external investment, no M&A activity, no headcount disclosure, and no public revenue figures. Go-to-market is supported by content marketing through the German and English websites, a planning Web-App for iOS/Android, an interactive "Infrarot-Haus" cost-comparison tool, trade show participation, and a free online quote-request funnel. The most recent material commercial signal is the release of the 2026 product catalog alongside continued product and ecosystem development including smart home integrations.
