The Biasi 3wood7 is a new generation of wood boiler that challenges our oil dependency. It is efficient, easy to use, and produces low emissions. With 120,000 Btu - this wood burining boiler is perfect for residential usage.

Unlike wood boilers from the past, the Biasi 3WOOD dispels the notion that wood boilers are labor intensive, inefficient and polluting. 3WOOD offers consistent high efficiency with a large heat exchange surface and secondary combustion chamber.

The Biasi 3WOOD wood boilers water-cooled grates, large finned firebox and secondary combustion chamber maximize the burn time and minimize wood consumption. Easy adjustments to the automatic temperature control, secondary air regulator, and flue gas damper enhance fire maintenance.For over 70 years, the BIASI foundry has maintained a reputation for precision pressure castings and quality control that exceeds all international standards. The 3wood7 wood boiler has 120,000 BTU/HR. All threads and fittings are compatible with North American controls and accessories. 3WOOD, the only ASME certified and ETL approved cast iron wood boiler on the market, embodies the design innovation of QHT BIASI.
