Attack SLX combi boiler for wood and pellets - efficiency and versatility
The combi boiler 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 levels of convenience and an impressive efficiency of up to 91.6%. With its robust construction made of special boiler steel and numerous innovative features, the Attack SLX Combi is a reliable and user-friendly companion for your heating needs.
High efficiency and efficient heating
Thanks to the highly efficient tube heat exchanger with mechanical cleaning lever and the advanced control system, the Attack SLX combi boiler achieves outstanding combustion efficiency. The integrated PID control continuously adjusts the fan speed, which, together with fuzzy logic, ensures optimal energy utilization. The special turbulators in the heat exchanger slow down the flue 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 biomass and CO2-neutral fuels.
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 loading chamber with a capacity of up to 200 liters is available for this purpose, which is suitable for logs up to 690 mm long.
For pellet operation, the boiler is equipped with a modern burner that is automatically fed with pellets via a screw conveyor. Switching between the two operating modes is easy using 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.
Comfortable fully automatic operation with pellets
In pellet mode, the Attack SLX Combi boasts convenient, fully automatic operation. The burner ignites and extinguishes automatically to reach the set buffer tank temperature. Burner cleaning is also fully automatic, significantly reducing maintenance requirements.
With the optional control via a room thermostat, you can conveniently monitor and adjust boiler operation remotely without having to enter the boiler room. This increases operating convenience and saves time.
Robust construction for longevity
The Attack SLX combi boiler is constructed from 6 mm thick, special boiler steel, ensuring a very long service life. The integrated cooling circuit safety device ensures maximum safety during operation and prevents overheating. With its sophisticated and compact design, the boiler is also space-saving and easy to install.
The Attack SLX series is designed for durability and reliability, so you can benefit from an efficient heating experience for many years.
Innovative control for maximum efficiency
The boiler is equipped with a modern LCD display that clearly shows all important operating statuses and diagnostics. The control system allows for the control of two heating circuits and precise buffer 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. Thus, the Attack SLX Combi supports not only efficient but also environmentally friendly combustion.
Environmentally friendly and cost-saving
With the flexibility to 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 help ensure the boiler meets strict environmental standards.
In addition, the optional pellet hopper with a capacity of 500 liters offers extra convenience as it allows longer operating times without refilling.
Summary
The Attack SLX combi boiler for wood and pellets is a versatile and efficient heat generator that offers both high levels of comfort and environmental friendliness. With the ability to switch between wood and pellet operation, it flexibly meets different heating requirements. The robust materials and innovative control technology make the Attack SLX Combi a sustainable and long-lasting solution for your heating needs.
If you value efficiency, ease of use and environmental friendliness, the Attack SLX combi boiler is the ideal choice for your home or system.
