Vitoflex 300-VF – fully automatic wood boiler


Take advantage of these benefits

  • Biomass boiler for dry to damp wood fuels
  • High efficiency of up to 92 percent
  • Minimal heat losses due to complete insulation
  • Output guaranteed up to moisture content of 45 percent
  • Automatic ash removal


Suitable for a very wide range of wood fuels

The Vitoflex 300-VF is suitable for burning damp spruce woodchips, pellets or residual wood from forestry and sawmills.

The flat moving grate is charged by means of a screw conveyor feed or an hydraulic feed with water-cooled feed neck. At the end of the grate, a screw conveyor transports the ash into a sealed ash container.


Low NOx technology reduces nitrogen oxide emissions

The Vitoflex combustion chamber is equipped with an air stage on the primary side for reduced NOx emissions.

In addition, this effect is amplified by a flue gas recirculation system (option). An energy conversion efficiency of up to 92 percent allows highly efficient operation even in modulating mode.
