The 3WOOD is a new generation of wood boiler that challenges our oil dependency. It is efficient, easy to use, and produces low emissions.
Unlike wood boilers from the past, the 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 3WOOD’s 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 3WOOD series is available in four sizes ranging from 75,000 to 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.

QHT BIASI 3-Pass Technology
|
|
1st Pass
Wood burns in a large,finned combustion chamber with water-cooled grates.
2nd Pass
Vented firebox gasses mix with very hot, preheated air in the secondary combustion chamber thereby enhancing oxidation.
3rd Pass
Remaining exhaust heat is given-up in a wide finned, self-cleaning passageway before exiting the boiler.

Compatible with single or two-stage thermostat. (For optimal performance two-stage thermostat
recommended..)
Heat exchanger is constructed of all stainless steel for maximum corrosion resistance and thermal
fatigue reliability.
Low profile "34 inch" design is lighter and easier to handle and leaves room for optional accessories.
Left or right side gas, electric, and condensate drainage connections on upflow models.
Integrated control board manages all operational functions and provides hookups for humidifier and electronic air cleaner.
An insulated blower compartment, a slow-opening gas valve and a specially designed inducer system make it one of the quietest furnaces on the market today.
