Boilers with feeder for coal

Komfort Eko PZ

Automatic boilers KOMFORT EKO PZ ensure high servicing comfort with low operation costs. They are equipped with automatic system feeding fuel to furnace chamber and highly effective retort burner of II generation. Design of burner nozzle and use of new fuel feeding system allows using fuels of better sinterability. Developed, but friendly control system ensures that servicing comfort can be compared with boilers using liquid and gas fuels.

Fuel feeder can be installed in the KOMFORT EKO PZ boilers on both sides. Moreover- boilers are equipped with substitute cast-iron grate allowing periodical combustion of the other fuels and use of equipment in the emergency situations. Heat exchanger of boilers is made of certified boiler steel of thickness 6mm. In addition, flue extension with adjustment of flue gas draught is standard equipment of the boiler.

5 lat gwarancji na szczelność wymiennika ciepła, 2 lata na pozostałe elementy i sprawne działanie kotła. 5 years of warranty for heat exchanger tightness, 2 years for the remaining components and efficient operation of boiler;
