Boiler for coal 5-25mm PROSAT WE - 5 class -20 kW with feeder on right side

Boiler Class 5 PROSAT WE 20 kW - an ecological boiler meeting class 5 standards in compliance with PN-EN 303/5 2012, with an automatic fuel dosing system - ecoal. The boiler is adapted to work in open central heating systems. A microprocessor temperature controller manages the entire combustion process as well as the operation of central heating and domestic hot water pumps. Boiler operation is limited to refueling in the tank, removing ash from the ash pan, and periodic cleaning of the convection heat exchanger channels from soot.
