Attack SLX Combi Pellet 25 kW Plus

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

The combination boiler Attack SLX Combi combines the advantages of a fully-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 great comfort and an impressive efficiency of up to 91.6%. With its robust construction made of special boiler steel and numerous innovative functions, 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 tubular heat exchanger with mechanical cleaning lever and advanced controls, the Attack SLX combi boiler achieves 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 into the heating water.

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

Flexibility through wood and pellet operation

The Attack SLX Combi is particularly impressive due to its flexibility. In wood gasifier mode you can simply run the boiler with logs or briquettes. A large-volume loading chamber with up to 200 liters is available for this purpose, which is suitable for pieces of wood up to 690 mm long.

For pellet operation, the boiler is equipped with a modern burner , which is automatically supplied with pellets via a screw. Switching between the two operating modes is easy using a swivel mechanism on the burner. This means you can 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 comfortable, fully automatic operation. The burner ignites and extinguishes automatically to reach the set target value of the buffer tank. The burner is also cleaned fully automatically, which significantly reduces maintenance costs.

With the optional control via a room thermostat, you can easily control and adjust the boiler operation remotely without having to enter the boiler room. This increases ease of use and saves time.

Robust construction for longevity

The Attack SLX combination boiler is made from 6 mm thick, special boiler steel, which ensures a very long service life. The integrated cooling circuit fuse ensures maximum safety during operation and prevents overheating. With its well-thought-out and compact design, 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 for maximum efficiency

The boiler is equipped with a modern LCD display that clearly shows all important operating states and diagnoses. The control enables the regulation of two heating circuits as well as precise buffer control. In addition, 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 reduce losses to a minimum. This means that the Attack SLX Combi not only supports efficient but also environmentally friendly combustion.

Environmentally friendly and cost-saving

With the 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. The low emissions and high energy efficiency help the boiler meet strict environmental standards.

In addition, the optional pellet container with a capacity of 500 liters offers extra convenience as it enables longer operating times without refilling.

Summary

The Attack SLX combination boiler for wood and pellets is a versatile and efficient heat generator that offers both high 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 facility.
