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.

Product features

Manufacture

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.

Effectiveness

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.

  • Ribbed chamber surface and three-pass flue gas flow for improved heat exchange
  • Burner flange on lower door for pellet burners

Safety devices

For a safe and reliable operation of the boiler, a number of safety devices are installed

  • Pressure relief valve 3 bar included in the delivery set
  • Safety heat evacuator - a tap-water-filled line passes through the upmost part of the boiler body. In case of overheating it is triggered open by a thermostatic valve (not included) to evacuate the heat off the boiler.
  • Exchangeable metallic ash grate protects the chamber base from the flame

This appliance complies with EN 303-5 and has CE Certification
