Today, the indoor climate specialist Kermi GmbH is one of the leading manufacturers in the building technology sector in Europe.
Affiliated to the ARBONIA climate division of the listed Arbonia AG Group, we work together with our sister brands as a strong European competence center for system services for heat and cold generation, heat and energy storage, heat and cold distribution, ventilation and air filtration.
True to the motto “sustainable heat for well-being”, Kermi GmbH offers optimally coordinated products and solutions for the heating revolution - for both new builds and modernization projects.
Kermi - A strong system thanks to perfectly coordinated products
Our high-performance and energy-efficient indoor climate solutions are perfectly coordinated and work perfectly as a system. They can be combined as required, interlock perfectly with each other and together show their full strength: The more components are linked, the greater the benefits - also in terms of sustainability. This means even lower energy costs and less CO2 with maximum heating comfort and an optimum room climate. The specially developed x-center control system controls the individual components of the Kermi system in an x-optimized way and ensures that all processes run smoothly and that the Kermi product range works in perfect harmony. Controllable via any mobile device using an app.
Kermi products for maximum efficiency and almost any application
The Kermi x-change dynamic pro heat pump offers additional efficiency in combination with Kermi storage heaters. The x-flair low-temperature radiator offers the perfect solution in combination with the heat pump, particularly in renovation projects. The heat pump radiator can be connected to existing pipes and makes optimum use of the low flow temperature, heats up efficiently and distributes the heat quickly. Decentralized and central domestic ventilation units for a perfect indoor climate round off our comprehensive and sustainable product portfolio.
Together in a strong brand alliance, we support the energy transition in Europe and the world.

Our Products

x-well residental ventilation
Health and well-being, value retention and energy saving
Within your own four walls, it ensures consistently high air quality and optimum humidity with a regular air exchange. Controlled domestic ventilation ensures the necessary air exchange between indoor and outdoor air. This regular air exchange is not only beneficial for the residents, but also for the building fabric.
Why controlled domestic ventilation?
Intelligent domestic ventilation is essential for energy-efficient buildings and the renovation of old buildings. Without sufficient ventilation, the proverbial “thick air” is created, which encourages bacteria and mold. In modern energy-saving houses, the tight construction prevents the natural exchange of air. According to § 6 of the EnEV, the building envelope must not only be airtight, but must also ensure the minimum air exchange for health and heating.
Central living space ventilation
- Ideal for passive houses and low-energy houses
- Convenient control
- Perfect integration
Decentralized domestic ventilation
- Individual ventilation for many requirements
- Pendulum ventilators
- Single-pipe ventilators/small room fans
- External wall diffusers

x-change dynamic pro air/water heat pump
Refurbishment & modernization. Many homeowners are reluctant to install a heat pump. However, these concerns are unfounded. Modern heat pumps have also been developed to meet the requirements of renovation and modernization projects. Regardless of whether you want to renovate your entire house to make it more energy efficient or just replace your heating system - a modern air/water heat pump adapts to your needs. Save energy, protect the environment and increase the value of your property.
Sustainable heating in your new build. Opt for a future-oriented heating solution and choose an x-change dynamic pro air/water heat pump. Use free energy from the environment to heat your new home in an environmentally friendly and cost-saving way. With the help of the integrated solar power function, the heat pump uses the surplus energy from your home's own solar system sensibly and efficiently. Enjoy maximum comfort at home and make a contribution to climate protection at the same time.
More power, more efficiency: cascade solutions. Our cascade solution is the right choice for large projects and high heating loads. Up to three x-change dynamic pro air/water heat pumps work together intelligently to ensure optimum efficiency and an output of up to 60 kW. Thanks to the intelligent control technology in the x-center pro controller, it always operates in the optimum efficiency range. We offer you a tailor-made solution for individual requirements.
Perfect addition: x-flair heat pump radiators, x-buffer hot water and buffer cylinder and intuitive control technology

Features the original x2 technology as standard
The therm-x2 Vmulti works according to the innovative serial flow principle. While all panels were heated at the same time with conventional steel panel radiator technology, the heating fluid flows through the front panel first with x2 technology. This results in energy savings of up to 11 % compared with conventional panel radiator technology.
