Attack SLX combination boiler for wood and pellets - efficiency and versatility

The combination boiler Attack SLX Combi The Attack SLX Combi combines the advantages of a full-fledged wood gasification boiler with the option of switching to fully automatic pellet operation. Whether you use wood, briquettes, or wood pellets as fuel, the boiler offers high comfort and an impressive efficiency of up to 91.6%. With its robust construction using special boiler steel and numerous innovative features, the Attack SLX Combi is a reliable and user-friendly solution for all your heating needs.

High efficiency and efficient heating

Thanks to the highly efficient tube heat exchanger with mechanical cleaning lever and advanced control, the Attack SLX achieves Combination boiler Outstanding combustion efficiency. The integrated PID control continuously adjusts the fan speed, which, together with the fuzzy logic, ensures optimal energy utilization. The special turbulators in the heat exchanger slow down the exhaust gases and ensure maximum heat transfer to the heating water.

With an impressive efficiency of over 91%, the boiler not only saves fuel costs but also represents an environmentally friendly heating solution, as wood and pellets are considered CO2-neutral fuels as biomass.

Flexibility through wood and pellet operation

The Attack SLX Combi is particularly impressive due to its flexibility. In wood gasification mode, you can easily operate the boiler with logs or briquettes. A large-capacity loading chamber with a capacity of up to 200 liters is available for this purpose, suitable for logs up to 690 mm in length.

For pellet operation, the boiler is equipped with a modern burner that is automatically supplied with pellets via an auger. Switching between the two operating modes is straightforward thanks to a swivel mechanism on the burner. This allows you to choose between manual and fully automatic operation at any time – depending on your personal preference and needs.

Convenient fully automatic operation with pellets

In pellet mode, the Attack SLX Combi shines with its convenient, fully automatic operation. The burner ignites and extinguishes automatically to maintain the set temperature of the buffer tank. Burner cleaning is also fully automatic, significantly reducing maintenance.

With optional control via a room thermostat, you can conveniently monitor and adjust boiler operation remotely without having to enter the boiler room. This increases user-friendliness and saves time.

Robust construction for durability

The Attack SLX combination boiler is made of 6 mm thick, special boiler steel, ensuring a very long service life. The integrated cooling circuit safety device provides maximum operational safety and prevents overheating. With its well-designed and compact construction, the boiler is also space-saving and easy to install.

The Attack SLX range is designed for durability and reliability, so you can benefit from an efficient heating experience for many years to come.

Innovative control system for maximum efficiency

The boiler is equipped with a modern LCD display that clearly shows all important operating states and diagnostics. The control system allows for the regulation of two heating circuits as well as precise buffer tank control. Furthermore, the burner can be controlled either via a room thermostat or a temperature sensor.

The innovative combination of PID control and fuzzy logic ensures continuous adjustment of combustion parameters to optimize heating performance and minimize losses. This allows the Attack SLX Combi to support not only efficient but also environmentally friendly combustion.

Environmentally friendly and cost-saving

With its ability to flexibly combine wood and pellets, the Attack SLX Combi significantly reduces your heating costs per season. By using biomass as fuel, the boiler also contributes to environmental protection. Its low emissions and high energy efficiency ensure that the boiler meets stringent environmental standards.

Additionally, the optional pellet hopper with a capacity of 500 liters offers extra convenience, as it allows for longer operating times without refilling.

Summary
