Modern and technically most advanced boiler of our production program. Thanks to its large scope of output modulation from 3.4 to 37.0 kW it can be used in various buildings. Its continuous dosage of output ensures the highest thermal as well as economic comfort, of course with minimum effect on the environment. Thanks to the new conception of multiphase ventilator the considerable noise limitation was achieved. Last but not least the control electronics was updated, it includes its auto-diagnostics and newly enables to optimise the program map with regard to the course of burning.

Also the condensation boiler body was innovated. The condensation body combines the exchanger with cooling front burner wall equipped with brand new type generation of burner BLUEJET®. Boiler version THERM 35 KDC is determined for heating and supply water warming in flow-heating way.
