High-Efficiency Biomass Combustion Technology

The Firematic 80–301 kW series features a modern two-zone combustion chamber combined with an automatically controlled moving step grate. This design ensures uniform fuel combustion, high efficiency, and stable operation even during partial boiler load.

An electronically controlled lambda probe continuously monitors the flue gas composition. Based on the collected data, the controller automatically regulates both fuel supply and primary and secondary combustion air. This guarantees maximum combustion efficiency while minimizing dust and gaseous emissions.

Thanks to intelligent control technology, the boiler automatically adjusts its operating parameters according to biomass quality and the building's current heating demand.

Automatic Cleaning System

To minimize maintenance requirements, Firematic boilers are equipped with a comprehensive automatic cleaning system. The moving step grate continuously removes combustion residues, ensuring proper airflow to the combustion chamber while maintaining maximum efficiency.

The fire-tube heat exchanger is fitted with automatic turbulators that clean the heat exchange surfaces during operation. As a result, the boiler maintains consistently high efficiency throughout the entire heating season without frequent manual cleaning.

Ash and fly ash are automatically transported by screw conveyors into front-mounted ash containers. Larger system configurations can also be equipped with external high-capacity ash containers, extending the intervals between emptying.

HERZ T-CONTROL Controller

All boiler functions are managed by the advanced HERZ T-CONTROL controller with a full-color touchscreen display. Its intuitive interface allows convenient configuration of operating parameters and provides continuous monitoring of the heating system.

The controller manages buffer tanks, domestic hot water production, mixing valves, circulation pumps, solar heating systems, and multiple independent heating circuits. Thanks to its modular design, the system can be expanded with dozens of additional control modules.

Remote monitoring and control via computer, tablet, or smartphone are also available, allowing users to supervise the heating system from virtually anywhere.

Automatic Fuel Feeding

Firematic boilers are compatible with various biomass feeding systems. Depending on the fuel type and storage configuration, screw conveyors, moving floor extraction systems, flexible pellet feeders, and pneumatic fuel transport systems can be used.

The highest-output models utilize dual fuel feeding systems that ensure uniform fuel delivery to the combustion chamber and reliable operation even under extremely high heating demand.

Ease of Operation

The high level of automation reduces daily maintenance to occasional fuel refilling and ash container emptying. Automatic ignition, combustion control, grate cleaning, heat exchanger cleaning, and ash removal significantly reduce routine maintenance work.

All major components are manufactured from durable materials resistant to high temperatures and intensive operation, making HERZ Firematic boilers ideal for continuous use over many heating seasons.

Supported Fuels

The Firematic 80–301 kW series is designed to burn premium-quality wood pellets that comply with current standards, as well as wood chips with a moisture content of up to 40%. Automatic combustion control ensures maximum utilization of the fuel's energy content while maintaining outstanding efficiency and low emissions.
