Installation
Boiler connection
Correctly connecting the boiler to the chimney is essential. The design should account for the home, boiler output, chimney and the entire heating system.

Household support
Green for Households grant programme
Eligible households can apply for a grant of up to €1,500 towards a new, modern heating appliance. Request a quote and we can help with the process, including the grant application.
Compact dimensions of the ATTACK DPX 15 boiler
Easier installation in a smaller boiler room
Compact dimensions and improved access to the electrical connections make the boiler easier to position. When selecting the output, consider the chimney height and cross-section as well as the heating system. The manufacturer recommends discussing the design with a service technician, chimney professional or heating-system designer.
Features and operation
How ATTACK DPX 15 works
Explore the loading chamber, combustion, cleaning, damper and available controls.
Loading chamber
82 litres for logs up to 350 mm
This compact boiler has an 82-litre loading chamber and accepts logs up to 350 mm long.
Combustion
Wood gasification technology
ATTACK boilers are designed with the environment in mind. Precisely controlled wood gasification is cleaner and more efficient than combustion in a conventional boiler. With efficiency of up to 91%, it uses less fuel and can reduce both heating costs and environmental impact.
Cleaning
Mechanical heat exchanger cleaning lever
The heat exchanger is cleaned with a mechanical lever. The product page says it can be positioned to suit the boiler-room layout.
Flue-gas extraction
Automatic flue damper
The damper opens when the loading door is opened and directs flue gas straight to the chimney. It closes automatically when the door is shut.
Two control options
Controls
STANDARD controls
The basic control is intended mainly for simple heating systems with a buffer tank.
PROFI controls
The PROFI version adds more control options. Its manual describes PID boiler control and manual adjustment of user parameters.
ATTACK DPX 15 boiler options
Compact footprint, practical operation
ATTACK DPX 15 combines a 15 kW output and compact dimensions with features that simplify installation, lighting and maintenance.
01
Connection to Viadrus U26
ATTACK DPX 15 makes it easier to replace an older Viadrus U26 boiler. It has the same G 2″ hydraulic connection size and the same connection spacing, simplifying installation.
02
Buffer tank
For higher performance, we recommend adding a buffer tank and an ATTACK Oventrop mixing unit.
03
Reversible door opening
ATTACK DPX 15 offers flexibility in the boiler room. You can choose the door opening direction to suit the available space.
04
Flue connection adjustment
Adapt the flue connection to the boiler-room layout. A correctly designed connection supports safe and effective flue-gas removal.

Detailed specifications
Technical data
The technical table on the Slovak product page lists efficiency at 91.3%; accompanying text gives 91% and up to 92%. The product page and manual state a minimum buffer tank volume of 400 l and a recommended volume of 800 l; the DPX 15 information sheets state a 600 l minimum. The table retains the product-page values, and these discrepancies are noted for verification.
