Steel boiler with natural air feed, controlled by a thermostatic draught regulator. Solid fuel boilers BW-A range in nominal output from 25 to 110 kW to satisfy the heating demands of medium to large sized spaces. They are engineered for burning solid fuel and provide the option for fitting pellet burners.
The boiler is manufactured from high quality steel with 5mm thickness. The combustion chamber has a large heat exchanging surface and low chamber impedance. Large firebox door ensures easy loading even of large chunks of wood.
To increase the heat exchange, the combustion chamber's surface is ribbed and designed for a three-pass flue gas flow. The mantle completely envelops the firebox for maximized usage of the heat. The boiler's body is insulated from the external conditions by very thick high temperature resisting wool. This series uses a thermostatic draught regulator that opens or closes a flap on the lower door, depending on the amount of air needed for the burning process.
For a safe and reliable operation of the boiler, a number of safety devices are installed
