Condensing gas Boiler Condens 100 20 CH1

Description

Condensing gas Boiler Motan Condens 100 20 CH1

(equipped with 3-way valve) for heating installations.

This Boiler is intended only for the heating installation. For the preparation of domestic hot water, a coiled Tank is required! Without a DHW Tank, it will NOT produce hot water!

Frendly environment - during operation it emits significantly reduced amounts of NOx, CO and CO2 - Class NOx 5;
Designed and built for maximum efficiency and economy in operation according to the latest EU legislative requirements - low energy pump;
The possibility of mounting in cascade;
Maximum efficiency: Efficiency class -4 stars **** (dir. 92/42/CEE);
Main stainless steel heat exchanger CIRCOND VALMEX (Italy);
SIT gas valve (Italy);
Fan with built-in gas-air nozzle SIT (Italy).
