Hard coal Seasoned wood Mixture of fine coal and hard coal Certified boiler steel (P265GH) with the thickness of 6 mm 4 year warranty for the leakproofness of the exchanger Movable grille for better ash removal (boilers up to 35 kW) Boiler has the highly efficient grille with the water flow Wide range of various capacities of boilers Possibility to adjust the combustion by means of the draught regulator (option) Easy operation and manual boiler control Device characteristics MJ-2 type boilers are popular heating devices with the lower combustion of solid fuels. Modern design and introduction of new technical solutions allow to minimize the amount of welded joints. Thanks to the use of three water laths located vertically, there was forced the labyrinthine circulation of fumes, that is a longer heat dissipation path, making the fact that these boilers are used to the energy maximum, using the natural gas flue. The boiler also has the cast iron movable grille and water grille, which effectively receives heat from the burning fuel. The application of the draught regulator allows you to adjust the boiler performance, and maintain the constant set temperature. Fuel: hard coal, seasoned wood. Specifications of the boiler Mj-2
