DPBi2, dual fuel, auto feed from hopper, manually load logs, wood.

DPBi2 are wood pellet boilers with a true multi fuel burn capability,  automatic feed system for biomass like pellet or grain and manually loading for logs, wood and wood waste to produce hot water for central heating system.

Can be used in both open / vented and closed / pressurised plumbing systems.

Power outputs range are from 16 - 75kW which roughly covers property of a floor areas from 200 to 850 m2 @ 3m height.

DPBI range of multi fuel wood pellet boilers, are the biggest and heaviest in size per their power output when compared to other brands of pelletized fuel burners we stock. These units are tested to over 30% of their stated output and come equipped with variety of electronic aides to boost their reliability and efficiency.

The DPBI, biomass boilers are capable of burning using auto feed system a wide variety of pelletized fuels like wood pellets, small pea coal, slack and some grains. They are also able to burn manually loaded solid fuels like wood, logs, peat, turf, coal, wood offcuts, garden leaves, shrubs and other wood originating products, loading is through middle door. Please see the cut away diagram.

The pelletised fuel of no more than 20mm cube is stored in a hopper, which is rigidly mounted on the side of the boiler. An auger delivers fuel in to the lower centre of the fire box chamber where air is being injected from surrounding air jets to excite and accelerate the flame front. Once the fuel is spent and the burn is complete, the remainder of ash falls down on to the tray below*.


DPBi2 biomass boilers in this range come equipped with a friendly to use colour display computer, mounted on top. The controller adjusts range of parameters in various modules like air fan speed, auger supply, multi water pump control, exhaust gas temperature and has ability to link with oxygen sensor as well as a gsm modem.

DPBi2 red pellet boiler range are design to circulate flame and fumes in the upper part, where main heat exchanger is located.

Hopper flame detection system is designed to operate to ensure safe workings of these units.


EN approved steel, for use with solid fuel flames, 5-6 mm laser cut plate with weld either side.
