The ATTACK DP Profi wood gasifying boiler is intended for economical and ecological heating of the family houses, small plants, work stations and similar objects. Wood is the main fuel for the ATTACK boilers. By full utilization of the feeding chamber there is possibility of the continual burning for 8- 12 hours.

Gasification of wood and the following combustion of the wood gas ensures optimal burning of all combustible contents. The combustion is regulated by the flue gas fan. Boiler body is isolated by a mineral wool. The boiler covering is treated by a powder paint.

Advantages of boilers Attack DP Profi

The ecological warm water boilers ATTACK DP Profi are intended for heating of dwelling houses and industrial objects. The boilers are constructed for combustion of the wood logs. It is possible to use any kind of dry wood, e.g. wood logs of the length adequate to the boiler type. The wood gasifying boiler ATTACK DP is a modern boiler that gets maximum from wood thanks to its technology and saves the environment by ecological combustion. The wood is a favourite fuel, as it produces comfortable warmth and grows right outside your door.


The wood gasifying boiler ATTACK DP Profi is controlled by an electronic regulator for regulation of temperature of the warmwater wood boilers. The Profi version of ATTACK DP boilers in comparison with the Standard version has advantage of the higher comfort of operation and the possibility of the boiler output modulation to achieve the optimal parameters of wood combustion. The regulator permanently measures the temperature of water in the boiler, displays its value and controlls the flue gas thermostat and the pump of central heating.
