More information

Fully automatic operation

From pellet feeding to ash removal

An auger feeder moves fuel into the combustion chamber. The boiler lights and controls combustion automatically, continuously cleans the heat exchanger and burner, and collects ash in a separate box.

ATTACK PELLET 30 AUTOMATIC Plus technical features

A pellet boiler offers convenient, automated heating.

Its level of convenience is comparable to a gas boiler or heat pump.

Fuel feed

Hopper and auger feeder

The boiler manages fuel feed, output adjustment and air supply. Pellets are delivered directly into the combustion chamber by an auger feeder (1.5–2.5 m), where they burn at 91% efficiency.

Pellet burner

Automatic combustion

ATTACK Pellet Burner Automatic provides fully automatic operation, including pellet feeding and ignition. Its key components are made from durable heat-resistant stainless steel. Safety features include burn-back protection and up to four safeguards against overheating.

Boiler cleaning

Automatic cleaning

The turbulators help keep the tubular heat exchanger clean. The pellet burner also cleans itself after each burn or at a set interval. Ash is automatically moved to a removable container, which can be emptied so the boiler can continue operating.

ATTACK PELLET 30 AUTOMATIC Plus boiler options

A practical solution for modernising the boiler room

Technical features presented as practical benefits for system design, installation and everyday use.

Buffer tank

For higher performance, we recommend adding a buffer tank and an ATTACK Oventrop mixing unit.

Pellet hopper

The pellet boiler comes with a 500 l hopper. An external fabric big bag can also be used. The large hopper holds enough pellets to keep the boiler running for an extended period.

Flue and connection on the ATTACK SLX COMBI PELLET boiler

Flue connection adjustment

Adapt the flue connection to the boiler-room layout. A correctly designed connection supports safe and effective flue-gas removal.
