Now in compact version and thus in all multi-panel Kermi steel panel radiators. THERM X2 THE COMPLETE ENERGY-SAVING PROGRAMME.

heating technology. The times demand a new generation of radiators: Therm X2. The energy-saving radiator. In a time in which energy costs are increasing constantly, legal requirements are becoming more stringent and customer desires for cosy and comfortable living are becoming stronger, Kermi provides a unique solution: Therm X2. The first and worldwide only steel panel radiator with serial flow-through, which saves up to 11% of energy, which at the same time ensuring 100% comfort – at all operating points. A milestone of heating technology, precisely adapted to the requirements of the new...

WITH THE UNIQUE PLUS IN COMFORT. In controlled operation, the rated heating load and required heat output diverge from each other greatly. Therm X2 sets a new standard in heating technology. With serial flow-through instead of parallel flow-through. Maximum radiation output even at low flow rates for optimal comfort. Decreased heating requirements due to improved insulation standards. up to Optimal dynamic response. shorter heating up time up to Corresponding addition in radiator design for the desired dynamic heating up output. Confirmation of the energy efficiency of all heating system...

The X2 principle. Conventional steel panel radiator technology with a triple advantage. THE X2 SOLUTION: SERIAL INSTEAD OF PARALLEL.

While in existing steel panel radiator The innovation for a larger competitive technology all of the panels are connected edge: Significantly better dynamics, optimal in parallel and thus flowed through at the comfort at every operating point and high same time, the Therm X2 uses a completely energy efficiency. new, unique principle: serial flow-through. This means that the front panel is connected in series with the panels behind it; the front panel is thus flowed through first. In controlled operation, the front panel's output is completely sufficient and the downstream panel heats up...

Greatly increased radiated portion MAXIMUM COMFORT AT ALL TIMES. for optimal heating comfort. DIN EN 12831 requires the following with regard to dynamic heating-up response: Conventional steel panel radiator “For rooms with intermittent heating operation, a reheating factor must be determined in agreement with the user.” The consequence: The heat output that has to be installed must be increased by the required reheating output. The result: More of the controlled operation takes place under partial load. This reduces the radiated portion and thus the comfort. On the other hand, VDI 6030...

shorter heating up time higher radiated portion Energy savings Example: Typ 33 060 100, Flow temperature 50° C Kermi Therm X2 steel panel radiators after 10 after 15 after 20 Mass flow rate Mean surface temperature [°C] Conventional steel panel radiator approx. 40 approx. 43 approx. 45 approx. 31 approx. 32 approx. 33 Thus the Therm X2 not only successfully counteracts the negative effects of DIN EN 12831 on the partial-load behaviour. It is also the only steel panel radiator that optimally fulfils the requirements of VDI 6030. For high customer satisfaction through a significant gain in...

Innovative technology that HIGH HEATING EFFICIENCY. is effective in saving energy. DIN V 18599-5 describe the energy efficiency of all heating system components in the German Energy Saving Ordinance confirmation. For radiators the standard reference values have up until now been used exclusively for this. Improved specific characteristic values have been a false indication up until now. Shorter heating up times, a higher radiated Based on the expenditure numbers currently The degrees of utilisation specified in portion and lower radiation loss and the DIN V 18599 likewise improve when...
