H4EKO-D
Fuel consumption is directly dependent on the quality and type of fuel used, as well as maintaining the cleanliness of the
internal heat exchange surfaces of the boiler. The smaller the chopped wood, the greater the boiler output, but the
burning time per one filling is shortened. Conversely, if we need less power, we can use thicker wood to extend burning
time per one filling. The position of the primary and secondary air flaps and the speed of the fan also affect the burning
time.
