An improvement in form of heat exchanger cleaning was introduced to increase the comfort of boiler operation. Depending on boiler model it can be started manually – using a lever or automatically using electric drive. The system uses economizers in form of springs, located in boiler chimney draughts, which allow comfortable cleaning of heat exchanger walls. Furthermore, economizers cause flue gas swirling, what increases heat recovery from flue gas and limits emission of dusts to the atmosphere.

It is possible to program times and period of cleaning in case of the automatically started system.
