Kermi therm-x2 steel panel radiators

With the innovative, patented x2-technology the therm-x2 radiator is setting new standards. With serial flow through the radiator panels, in comparison to conventional radiators, it saves up to 11 % more energy, generates up to 100 % more comfortable radiant heat , and its heating period is up to 25 % faster. Another huge advantage: Thanks to these strengths, the therm-x2 harmonises perfectly with modern heat sources, in particular with the heat pump.

  • In three different attractive looks
  • With energy-saving x2-technology
  • For all heat sources: oil, gas, or remote heating, solar energy or condensing technology
  • Wide range of sizes and colours
  • Perfectly suited for new-builds and refurbishment
  • Top cover and side panel standard
  • Comprehensive programme with short delivery times

x2-technology in every Kermi steel panel radiator

The original x2-technology is exclusive to Kermi steel panel radiators. A brilliant invention: In contrast to conventional radiators which heat up their panels simultaneously, the x2-technology works with serial flow. First of all, the front panel provides warmth quickly and ensures maximum comfort. The lower temperature of the downstream panel in contrast reduces the heat losses to the outer wall. Steel panel radiators with x2-technology are suitable for all heat sources and always operate efficiently – oil, gas, or remote heating, solar energy or condensing technology.

The new electric steel panel radiators x-therm +e are simple to install, easy to operate and efficient in operation. These radiators can be installed anywhere, independently of central heating. The electric radiators are also practical, for example, in rooms that are rarely used, in holiday homes, or when refurbishing. The x-therm +e is practical between the seasons too if it means that the central heating does not need to be started up. Easy to operate, the controller allows for precise control and the electric radiator provides extremely high output and consistently comfortable temperatures. At <0.5 watts, the standby consumption is extremely low. And: Self-generated electricity from solar panel systems makes its use even more cost-efficient.

Kermi steel panel radiator colours

Most of our radiators are of course painted in the classic Kermi white (RAL 9016). Steel panel radiators can be white – but they do not need to be! Play with colours and select your radiator in your favourite shade of colour.

You can select from our extensive colour concept. In addition to white and the major sanitary colours, the Kermi special editions are particularly inspiring. Contemporary and aligned with the stylistic realms of modern living. As for example the “Soft edition” with its luxurious, silky-smooth matt surfaces. Or the “Nature edition” with fresh, expressive tones of nature. While the “Ethno edition” is oriented toward the warm, vibrant colour spectrum of exotic cultures, the “Metallic edition” with its vivid surfaces brilliantly accents the glamorous trend of the '50s. You can also choose finishing in any RAL CLASSIC colour you like apart from this colour programme. You can always rely on a high quality, durable surface.

Steel panel radiators – coatings for special requirements

  • Anti-corrosion coating
    In the spray zone around showers and toilets or urinals in private and public areas, the radiator coating requirements are less demanding than in rooms with an aggressive and/or humid atmosphere. If radiators require greater protection on account of these locations, a coating that complies with DIN 55 900 is not enough. Here, however, there are special requirements for the appearance and feel of the coating in addition to protection. Kermi offers a more inexpensive anti-corrosion coating for these applications. Powder coating is possible to the usual high Kermi standard according to the Kermi colour concept. For these applications, anti-corrosion coating offers optimal corrosion protection and an attractive appearance.
  • Hot-dip galvanised
    Rooms with an aggressive and/or humid atmosphere, e.g. commercial operations, such a butcher shops, saunas, swimming pools, or areas with salt-laden air near oceans, present extreme challenges for radiator coatings. The same is true for rooms that are regularly wet-cleaned with a high-pressure cleaner. Hot-dip galvanising provides the best possible corrosion protection for these areas. The hot-dip galvanising process produces an irregular surface. For this reason, coating with a textured paint in white (RAL 9016) follows to provide a uniform appearance.
