THERM 18 KDZ 5

The THERM 18 condensing boiler series combines top technology, based in the latest findings in the field, and state-of-the-art components allowing active control of the combustion operation with regard to gas consumption, preventing unnecessary energy loss. The boilers have stainless exchanger with cooled front burner wall. The new type of the gas valve in combination with the burner provides a high level modulation. The regulation ratio of this type of boiler is then 1:10 and the minimum output starts at 1.8 kW. The boiler represents the PREMIUM Condens series with superior technological design.

Thanks to the broad range of output modulation, from 1.8 kW to 19.0 kW, the boilers are designed to be used in low-energy buildings with low heat loss. The THERM 18 KDZ 5 version is designed for central heating and for heating household water in an integrated stainless tank with a capacity of 55 litres.
