The HERZ firematic-E 80-101 ist ein biomass boiler with an integrated electrostatic filter, designed for burning wood chips or pellets. Compact, high efficient and economical.
The great advantages of HERZ firematic-E 349-501
- Lateral insertion of the wood chips and wood pellets into the combustion chamber by a double-insertion screw.
- The step grate elements are cleaned by moving the moving grate. These are special, high-quality cast segments. This ensures optimum air supply through the clean combustion grate.
- The combustion chamber is cleaned by automatic tipping of the combustion ash via tipping grate. The discharge screw underneath transports the ash directly into the ash box.
- The heat exchanger surface gets cleaned automatically via the integrated turbulators (by lifting and lowering), even during heating operation and therefore kept clean without manual effort. Consistently high efficiency due to cleaned heat exchanger surfaces ensures low fuel consumption.
- The fly ash is transported to the front ash hopper via screw.
- The ash accumulating in the combustion chamber is discharged into the ash screw below and automatically transported into the external front ash boxes.
- The removable ash box with wheels enables simple and comfortable emptying of the ash.
- The built-in lambda sensor, which permanently monitors the residual oxygen and reacts to different fuel qualities, ensures that perfect combustion values and the lowest emission levels are always achieved.
- The lambda probe regulates the air and material supply and thus always achieves the cleanest combustion, even in part-load operation.
- The results are low fuel consumption and the lowest emission values even with different fuel qualities.
- The integrated electrostatic filter operates according to the electrostatic principle. Here, the fine dust particles flow through the exhaust duct with the exhaust air. Electrons are released by a high-voltage electrode, which move to the wall by electrostatic forces.
- In the process, the fine dust particles are loaded and also moved to the wall. The fine dust collects on the wall and clumps together to form coarse flakes. These deposits are simply removed during automatic or mechanical cleaning.
- Due to the compact design the insertion and assembly can be done very fast & easy.
Structure electric filter
The electrostatic filter operates according to the electrostatic principle. The high-voltage electrode, which is positioned exactly in the middle of the filter tube, has the task of negatively charging the fine dust particles; this process is called ‘ionisation’. The high voltage is generated by a separate module, which can be mounted on the right or left side of the boiler. The negative charge of the particles causes them to stick to the cleaning basket. The basket is then pulled upwards by the cleaning mechanism and then dropped downwards with the additional help of a spring. As a result, the dust particles fall through the boiler’s heat exchanger and are transported fully automatically by the ash discharge screw into the front-mounted ash box.
Flue gas condenser for additional heat recovery

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).
