Ribbed chamber surface and three-pass fluegas flow for improved
heat exchange
Steel boiler with intelligent controller and electric fan for
forced airfeed. Wood-fired boilers WB-S Active range in nominal
output from20 to 110 kW to satisfy the heating demands of medium to
large sizedspaces. They are engineered for burning solid fuel and
provide theoption for fitting pellet, oil or gas-fired burners.

Product Features
Combustion chamber with large heat exchangingsurface and low
chamber resistance
Large firebox door ensures easy loading evenwith bigger wood
chunks
Burner flange on lower door for fitting gas, oil,or pellet
burners
Safety devices :1) Pressure relief valve 2,5 bar incl.in the
delivery set2) Safety heat evacuator a tap-water-filled line
passesthrough the upmost part of the boiler body. In case
ofoverheating it is triggered open by a thermostatic valve(not
included) to evacuate the heat off the boiler.
Exchangeable metallic ash grate protects thechamber base from
the flame

Electronic control unit controls the combustionby modulating the
fan speed. Optional control ofcirculation pumps for DHW and central
heating.
Electric fan for forced air feed optimizes thecombustion and the
fuel consumption rate
