Wood chip-/ pellet boiler
firematic 20-60 kW

Power range 6 till 60 kW

The HERZ firematic 20-60 kW is a biomass boiler for wood chips and wood pellets. Compact, high efficient and economical.

  • The cleanest combustion thanks to Lambda probe control even with variable fuel quality.
  • The quiet operation of the boiler is thanks to its high-quality system components.
  • The lowest emission values to protect our environment

The great advantages of HERZ firematic 20-60 kW

  • Side load of wood chips or wood pellets into the combustion chamber.
  • Complete cleaning of the grate due to automatical tipping on a cleaning device.
  • Due to the clean combustion grate an optimum air supply is guaranteed
  • Minimizes the manual cleaning requirement.
  • The heat exchanger surface gets cleaned automatically via the integrated turbulators, even during heating operation, no manual cleaning necessary.
  • A consistently high level of efficiency thanks to cleaned heat exchanger surfaces enables low fuel consumption.
  • The fly ash is taken into the front ash container via a discharge screw.
  • Via two ash discharge screws the combustion ash and fly ash is automatically transported into the ash container(s).
  • The removable ash container(s) with wheels enables simple and convenient emptying of the ash.
  • A built in lambda probe, which monitors continuously the flue gas content values, detects fuel quality changes and ensures optimum combustion and low emission values.
  • The Lambda probe controls the primary and secondary air supply ensuring complete combustion, even in partial load operation.
  • The results are low fuel consumption and the lowest emission values even with different fuel qualities.
  • Due to the compact design the insertion and assembly can be done very fast & easy.


User-friendly touch-controller T-CONTROL

  • Convenient menu and simple screen layout
  • Possibility for remote visualization and remote maintenance via smartphone, PC or tablet PC
  • Data transfer and software updates via USB stick
  • Possibility of Modbus-Communication

Cascade operation

Using the HERZ T-CONTROL, up to 8 HERZ boilers equipped with T-CONTROL can be switched to cascade (CAN BUS). A special advantage of the cascade arrangement is the efficient utilization of the boiler at lower heat consumption (eg in the transitional period).
