ATTACK DPX COMBI Pellet is an ecological wood and pellet boiler of the 5th emission class, which offers high-quality construction. High combustion efficiency of up to 91% saves significant heating costs. The choice of fuel selection provides an economic advantage and high comfort. Changing fuel is simple and can be handled by everyone. The boiler uses the design, construction, and all features of the DPX boiler with PROFI regulation. It is equipped with a fully automatic Pellet Burner Automatic for convenient and fully automatic pellet combustion and burner cleaning.
The wood and pellet boiler is suitable for every type of house
A wood gasifying boiler with strong power and high efficiency is suitable for every type of house. Take advantage of the opportunity to get a new boiler with the Green Households program.
Boiler connection
Correct connection of the boiler to the chimney is very important. Every house has a different height and area. When choosing the right type of boiler for your house, the power to the chimney and the heating system is important. We always recommend consulting this topic with a service technician, chimney sweep, or designer.
Extra-large loading chamber
ATTACK DPX COMBI Pellet is also ATTACK DPX equipped with an extra-large loading chamber for power ranges 25 – 35 kW (100-110 liters) with a length of (550 mm to 650 mm). For power ranges 40 – 50 kW (128 liters) with a length of (750 mm). Thanks to the large chamber, you save time on wood preparation.
Practical advice for wood and pellet boilers
Boiler care
Find out everything necessary about wood boilers. How to quickly and effectively ignite the boiler. Why tar can form and how to correctly clean the boiler.
Effective ignition of a wood boiler
We manufacture boilers to have the least possible impact on the environment, which we consider essential for life. Compared to combustion in a classic boiler, wood gasification technology is highly ecological, efficient and significantly less burdensome to the environment. Gasification is carried out using precisely controlled technology. This improves the overall efficiency of wood combustion, reaching values of up to 91%. Higher efficiency is reflected primarily in costs, as you consume less fuel.
Pellet burner
ATTACK Pellet Burner Automatic takes care of fully automatic operation during pellet burning. The burner handles ignition, controlled start, or controlled combustion process itself. In the production of the combustion chamber, grate, igniter plate, and burner scraper, we used high-quality heat-resistant stainless steel. In addition to high quality and comfort of the burner, operation safety is a matter of course. We equipped the burner with safety elements against back-burning and up to 4-fold protection against overheating (emergency, boiler, and flue gas thermostat, cooling circuit).
- Suitable for everyday heating
- PID regulator – more precise and continuous control of fan speed and Fuzzy Logic control sensors
- Controls 2 pumps (heating circuit pump + accumulation tank or DHW charging pump)
- For solutions with an accumulation tank – built-in tank charging logic and discharge protection
- Simple operation and display with current operating information (boiler temperature, flue gas temperature, temperature in the accumulation tank)
- Parameter monitoring (fan operation, DHW/accumulation tank charging pump operation, circulation pump operation)
- Automatic boiler shutdown after fuel burnout
