What Kermi does

Kermi GmbH is a German manufacturer of integrated room climate solutions, headquartered in Plattling, Lower Bavaria, with additional production sites in Stříbro and Opočno (Czech Republic). Founded in 1960 and operating under MBT Climate within the Arbonia Group, the company employs over 1,000 people and serves residential, commercial, and institutional customers across more than a dozen European countries. Its product portfolio spans heat pumps (x-change dynamic series using R290 refrigerant, A+++ efficiency, COP up to 4.48), flat panel and design radiators (therm-x2, Tano, Ineo, Oni, and 20+ other lines), underfloor heating and cooling (x-net), residential ventilation with heat recovery (x-well), heat storage tanks (x-buffer), split air conditioning (x-fresh), and control systems (x-center).

The company's underlying technology stack is built on thermodynamic and hydraulic engineering rather than software: patented therm-x2 radiator technology, heat-pump-compatible low-flow-temperature radiators (x-flair), a cascade collector (Kaskadensammler) enabling up to five heat pumps to share a single hydraulic circuit up to 150 kW, and integrated controls with remote-maintenance capability. Products carry recognized quality signals including 2025 iF Design Award and Red Dot Design Award wins for the Tano radiator and energy-class certifications supporting eligibility for German KfW subsidies of up to 70%.

Kermi's business model is hardware-driven, with revenue generated primarily through unit sales of heating, cooling, ventilation, and storage systems to SHK trade partners, wholesalers, housing developers, planners, architects, and—indirectly—private homeowners served via the Fachpartner channel. Go-to-market relies on a deep regional network of trained Fachpartner installers supported by field sales representatives (Gebietsleiter), with supplementary revenue from a direct spare-parts e-commerce shop and professional services including technical consultation, training, and after-sales support. Pricing is quote-based and not publicly disclosed. Marketing mixes professional tools (BIM data, CAD models, calculation programs), trade fair presence (ISH), digital content, and brand investment including a Bundesliga sponsorship with 1. FC Union Berlin from August 2025.
