ECONO traditional coal boilers are designed for traditional coal and wood burning using natural chimney draft. They are intended for heating residential and industrial spaces ranging from 30 to 350 square meters and for producing domestic hot water. The boiler’s heat exchanger is made of certified sheet metal with a thickness of 5 mm. The regulation of the amount of air required for an effective combustion process is done using an adjustment screw on the ashpan door. The boiler also has the option to install a draft regulator, allowing for automatic control of air intake.
