THERM 14 KDZN 5

The OPTIMUM Condens boiler series provides an optimal price/performance ratio. The THERM 14 condensing boiler series is made of attested components. The condensing body with stainless exchanger provides long service life and the top burner high efficiency and ecological operation. The shape and dimensions of the exchanger tube head limit the settlement of scale and sedimentation. Naturally, the boilers have the option of equithermic regulation, silent operation, and the flat dwellers will appreciate their compact dimensions.

The boiler has a heat output from 3.2 kW to 14.8 kW. For household water heating, the maximum heat output of 14.2 kW is reserved. The integrated stainless storage tank with a capacity of 55 litres provides long service life and sufficient thermal comfort.
