Hard coal Seasonal wood Wood pellet 6 – 8 mm Approved steel for boilers P265GH with a thickness of 6 mm 4-year-warranty for a tightness of the exchanger Automatic combustion of the boiler and work control Boiler’s control panel of 2’nd pump Highly-efficient burner with the movable grate The boiler is equipped with two combustion chambers Possibility to adjust the combustion using the draught regulator Increased thermal efficiency Support of the mixing valve Room controller Device characteristics Biotec Kompact boilers are fully-ecological, two-furnace boilers with an effective burner for the combustion of pellet and additional traditional combustion chamber. These are devices of a relatively small size (making them suitable for installation even in small boiler houses), while having the double combustion chamber. The lower chamber is equipped with the automatic combustion burner for the combustion of pellets. In turn, the upper part with the water grate allows the combustion of traditional fuels, such as coal and wood. With this design solution, we get complete freedom in the choice of fuel to be used. Technically-advanced controller ST 976 provides high comfort of use and trouble-free operation. Both in the case of fuel combustion in a conventional grate, as well as pellet combustion, there will be maintained optimal combustion conditions, which ensure high efficiency of the boiler. Fuel for the automatic feeder: wood pellet 6 – 8 mm. Fuel for the traditional combustion chamber: seasonal wood, hard coal. Specifications of the boiler Biotec Kompact
