Log wood / pellet combination boiler
pelletfire 20-40 T-Control

Leistungsbereich 6 bis 40 kW

The HERZ pelletfire 20-40 is a combination of a log boiler and a wood pellet burner. Especially the continued operation after burning of all logs makes the heating with a combi-boiler comfortable!

The already proven technology and the know-how from the HERZ pelletfire (from the year 1996) was used for further development regarding efficiency and comfort.

The multifunctional pelletfire is a perfectly paired combination of a log wood boiler and wood pellet boiler.

The great advantages of HERZ pelletfire

  • The revolutionary double vortex combustion chamber ensures optimum mixing of the combustion gases with oxygen.
  • The flame is distributed across 2 chambers and therefore a highly efficient combustion is ensured.
  • The combustion chamber consists of heat-resistant fireproof concrete (SiC) ➠ no sheet metal parts ➠ no wear and tear ➠ which means DURABILITY
  • Due to the separate combustion chambers there can be flexible switched between log wood and pellets operation.
  • If the buffer or heating circuits require heat after burning all logs, the operation is automatically continued with wood pellets.
  • Complete cleaning of pellets-combustion grate which automatically tips ash to extraction point. Minimizes the manual cleaning requirement.
  • Due to the clean combustion grate a optimal air supply is guaranteed.
  • The ash from the combustion chamber is dropped into the large ash bin below.
  • Unchanged, 1000-times proven combustion system since 2003
  • The heat exchanger surfaces are automatically cleaned via the integrated turbulators, even during heating operation, eliminating manual cleaning.
  • A consistently high level of efficiency thanks to cleaned heat exchanger surfaces enables low fuel consumption.
  • The integrated, extractable ash boxes allow an easy ash disposal.
  • The automatic ignition of the inserted logs with pellets is possible as standard.
  • Made of high heat-resistant steel – for longest lifetime
  • 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 air supply and ensuring complete combustion, even in part load operation.
  • The results are low fuel consumption and the lowest emission values even with different fuel qualities.
  • HERZ offers a variety of wood pellet discharge systems including flexible screw discharge, suction system or manual hand filling to suit different room situations.

EASY, MODERN AND COMFORTABLE
