DEFRO CLASSIC PLUS hand-loaded boilers are a design with horizontal flue gas channels, suitable for upper combustion of solid fuels. They are intended for heating buildings with an area of up to 250 square meters. Primary fuel: anthracite coal in nut size and anthracite coal in fine size. Alternative fuels: a mixture of anthracite coal in nut size and fine size, seasoned wood, and wood waste. The combustion process is facilitated by forced air supply and controlled by an electronic regulator, allowing for more precise temperature regulation and increased user comfort. The multipoint air delivery system to the loaded fuel zone increases the stability and efficiency of the boiler’s operation.
