HERZ pelletfire - Heating with log wood and pellets

The HERZ pelletfire  is available in three  sizes from 20 to 40 kW and is a perfectly coordinated combination of a log wood boiler and a pellet boiler. For those who want to enjoy full independence, heating can be done either traditionally with log wood or fully automatically with pellets, depending on the need. Thanks to separate combustion chambers, it is easy to switch between log wood and pellet operation. If there is still heat demand from the buffer tank or heating circuits after the log wood has burned, the heating operation is automatically continued with pellets. For even more convenience, the automatic ignition function is available, which can automatically ignite not only pellets but also log wood, depending on requirements.

Due to the built-in lambda probe perfect combustion values and the lowest emission values
are always achieved.. The heat exchanger surfaces are automatically cleaned and maintained by the integrated turbulators, even during heating operation. This ensures consistently high efficiency and reduced fuel consumption.

Combined boiler with integrated suction hopper for even more convenience

To continue meeting customer needs, HERZ has expanded the combined boiler with a version featuring an integrated suction hopper. With the integrated suction hopper (75-liter capacity), approximately 49 kg of pellets are stored temporarily in the boiler. This means that only 1-3 pellet deliveries from the storage room to the boiler are needed per day. The suction times can be freely selected, allowing the boiler to be automatically fed with pellets via the integrated suction hopper.
