Product Overview & Application Area
The Attack SLX 35 Pro wood gasification boiler is a log wood boiler for central hot water heating systems in single-family homes, larger residential buildings, holiday homes, and comparable properties. With a nominal output of 35 kW, it is suitable for systems where a powerful wood heating system with buffer tank operation is professionally planned and installed.
The boiler is designed for dry split logs and operates on the principle of wood gasification. The PROFI version uses electronic boiler control that manages operation based on boiler and flue gas temperature, thereby supporting controlled combustion in heating mode.
Technology & Equipment
The ATTACK SLX 35 Pro is designed as a wood gasification boiler with an induced draft fan. The boiler body is made of welded steel plate; wood gasification is prepared in the loading chamber, while combustion takes place in the downstream combustion chamber.
In the rear area, there is a tube heat exchanger with turbulators. These support heat transfer and facilitate regular cleaning of the heat exchanger. The PROFI control manages the induced draft fan and enables operation based on boiler and flue gas temperature.
Everyday Benefits
The large loading chamber and the permissible log length make daily operation with split logs easier. By integrating a suitable buffer tank, the generated heat can be stored and released to the heating system as needed.
The technical design with return temperature boosting, buffer tank, and safety cooling circuit is designed for stable operation in the boiler room. Regular cleaning, suitable fuel, and professional adjustment remain crucial for reliable operation.
System Integration & Compatibility
The Attack SLX 35 Profi is integrated into a hot water heating system and should be operated with a sufficiently sized buffer tank. For this performance class, a recommended buffer volume of 2,500 liters is specified.
For operation, suitable chimney draft, return temperature boosting to maintain the minimum return temperature, and the required safety devices must be taken into account. The specific design must always match the system, the building, and the heating load.

Installation
The installation of the wood gasification boiler must be carried out by a qualified person and must match the existing heating system, the chimney, and the buffer tank concept. For operation, a suitable chimney draft, return temperature control, and the prescribed safety devices must be taken into account.
The boiler is intended for installation in the boiler room. When integrating it, the requirements for the installation room, flue gas routing, heating water quality, return temperature, and electrical supply must be observed.
Notes
Dry split logs are intended as fuel. For clean and stable operation, the wood should be sufficiently dry and match the permissible log length.
The boiler is not intended for installation in living spaces. Cleaning, maintenance, and operation should be carried out in accordance with the operating instructions to maintain combustion, heat transfer, and operational safety.
