In Ukraine, many people have been switching to renewable heating sources in recent years. In rural areas, small (10-40 kW) solid fuel boilers are often installed. The fuel for them is made from wood residues, branches, corn cobs, and stalks. This is quite economical.
The video shows such a boiler running on wood chips. The boiler is controlled by an automatic unit that maintains a constant temperature of the coolant and controls the air supply. A control panel on the wall controls the fuel bunker, feeds fuel into the boiler, and periodically stirs the fuel to prevent it from clumping.
