Boiler for wood pellets with regulated output of 8–30 kW are intended for heating of dwelling houses and industrial premises. Boiler can be accessorized with electrical heating device of 2,4–6 kW output, equipped with own operation and emergency thermostat.

Basic part of the boiler is a water cooled boiler body. Welded piece of the body is made from special boiler steel plates of 4–6 mm thickness, which guarantees long lifetime of the boiler. Exchanger is tubular, with turbulators improving heat transfer into the heating water and enabling exchanger cleaning to ensure balanced efficiency.

Fuel is burned in the stainless steel burner, intended for combustion of the wood pellets. Fuel is automatically ignited by electrical spiral, built into the burner. Optimal burning conditions and output regulation are provided by electronically controlled fuel feeding and air inlet, following the parameters of heating and d.h.w. warming, required and set by the user. Burner, combustion chamber and exchanger are constructed to ensure optimal burning of all combustible materials. Boiler body is isolated with mineral wool, design is completed with powder-treated coating.

The ATTACK Pellet Automatic Plus boiler is equipped with system for automatic cleaning of tubular boiler exchanger in intervals adequate to the automatic ash removing into detachable box.

Construction and description

Boiler constructively consists of combustion chamber with partitions and tubular heat exchanger. Beyond the heat exchanger, the flue gas goes into collector with chimney, that can be horizontally or vertically oriented by turning the flange for 180°C. There is a wood pellet burner built-into the boiler body.

Podávač palivaThe boiler is equipped with spiral fuel feeder (1,5 m), ensuring continual fuel dosing. The ATTACK Pellet 30 Automatic Plus boiler can be delivered with pellet container of 500 l volume (dimesions: 720×1 240×830 mm).

The „big-bag“ – the external textile tank can be used as an alternative.

By wood pellets combustion in the ATTACK® boiler, there is minimal ash production. Amount of ash depends on quality of pellets and represents approximately 1 % of the consumed fuel.

The ATTACK Pellet Automatic Plus boiler is equipped with automatic system for ash removing into detachable box. Box of appropriate volume has to be emptied one time pro heating season, according to the season and intensity of boiler operation. Boiler can be also accessorized with electrical heating device of 2,4–6 kW output.
