The triple air circulation contributes to the high efficiency of the combustion process.

  • Primary air, which facilitates the firing of wood, is supplied under the grate.

    Secondary air is distributed to the rear wall of the combustion chamber. It ensures efficient combustion of the gases, reducing smoke and the emission of harmful substances into the environment.

    The air curtain is a secondary source of combustion air, the jet of which sweeps the glass, effectively removing soot particles and limiting their deposition on the glass.

    The hearth plate, in the form of a two-piece cast iron grate, helps to distribute air evenly over the entire base of the stove reducing the possibility of local overheating̨ of the surface,

Control of the air supply is intuitive in the form of two separate dampers - one for primary air and one for secondary air. The movement of the sliding elements is smooth and quiet, ensuring user comfort.


  • The proven TERMOTEC solution

    The side sections of the combustion chamber of the K11 stove are equipped with TERMOTEC, a heat-accumulating material that increases the temperature in the firebox. This ensures more efficient combustion and longer heat retention.

  • Flexibility of connection

    The K11 stove can be installed with a top or rear connection. Connecting the stove from the top saves space, while connecting from the rear makes the pipes less visible, which can be beneficial for those who care for a minimalist look. The choice between top or rear connection depends on personal preference, installation conditions and the aesthetics of the room.
