Modern and technically most advanced boiler of our production program. Thanks to its large scope of output modulation from 1.8 to 19.0 kW it can be used in buildings with low energy loss, such as apartments or modern houses. 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. Increased heat output for DHW heating – 23.5 kW, ensures high comfort of domestic hot water supply.
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 18 KDC is determined for heating and supply water warming in flow-heating way.
