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.

EASY, MODERN AND COMFORTABLE

User-friendly touch-controller T-CONTROL

  • The central control unit for:

    • Combustion control with lambda probe
    • Buffer management module
    • Weather-guided control for 1 mixed circuit (including outside sensor)
    • Control for domestic hot water preparation (via hot water tank or buffer with
      fresh water modul)
    • Return temperature rise
    • Lambda probe control (controls combustion air and fuel supply)
    • Activation for motorized valve for rapid heating of heating circuits in buffer operation

  • Convenient menu and simple screen layout ensures maximum user-friendliness

  • Offers extension possibilities up to 30 external modules:

    • Controlled heating circuits (actuator drive and pump)
    • Solar circuit control
    • Frost protection monitoring

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).
