The area of the heating surfaces is record large, they are directly heated by flame and cooled by air. A large air-tight firebox makes it possible to effectively use the stove in the mode of continuous burning.
Special calibrated orifices supply hot air for the complete burning of exhaust gases. Convective heat-exchange pipes throughout the cross section and length, from the beginning to the end, are located directly in the flame. The shape of the firebox is that of the flame of the freely burning solid fuel. You can warm up food on the upper horizontal surface heated with the flame.
The front and rear surfaces on which convective pipes are located take full part in the convective heat exchange. A large replaceable grate ensures regular burning throughout the area of the firebox. Ashes drop down to the ash box through the grate apertures. With a capacious pull-out ash box you can remove ashes, not interrupting the process of burning. Inlet holes of convective heat-exchange pipes are higher than the floor level, which is good for free convection of the heated air. The boiler has a built-in stable base with holes for being fixed to the floor.
