An automated hopper and multi-stage heat recovery system built for large, demanding heating loads.

Sensors confirm fuel is present as the adjustable auger feeds the firebox.

Large-capacity hopper runs for days between refills.

Three heat exchanger stages recover more heat and cut fuel use.

Accessible cleanout doors and large ash pans keep upkeep simple.

Turbulators pull extra heat from exhaust before it reaches the chimney.

A durable burn crib keeps the fire burning hot and clean.
Air distribution and triple-pass heat recovery, step by step.

Fresh air is drawn into the furnace to provide the oxygen the firebox needs for combustion.
Pushing through the "Omni-O," positive and negative air pressure forces air around the fire cradled within the firebox, maintaining consistent airflow for efficient combustion.
Super-heated air enters a twisting, water-surrounded chute, transferring heat to the surrounding water.
That same hot air travels through two sets of water-surrounded heat exchanger tubes, moving down one set and back up the second to maximize heat transfer.
After transferring much of its usable heat to the water, the cooler exhaust air exits through the Class-A insulated chimney.
Designed to handle large commercial, agricultural, industrial, and multi-building applications where a standard residential furnace may not be enough.
Burns wood chips, pellets, and other compatible biomass fuels, giving you the flexibility to use whatever fits your operation.
Automated fuel delivery and temperature control reduce the need for frequent loading and monitoring, making it easier to maintain consistent heat.
Distribute heat to multiple buildings across a property with one centralized system, simplifying heating for connected spaces.
A high-efficiency, multi-fuel design with low fuel consumption and extended burn times keeps operating costs down.
Manufactured in the USA with 409 Titanium Enhanced Stainless Steel and backed by a 20-year limited warranty, built for dependable long-term performance.
Dependable, centralized heat for offices, facilities, and other commercial spaces with larger heating demands.
Heat for barns, farm buildings, livestock areas, and other agricultural spaces through cold-weather conditions.
Heats large open warehouse spaces, storage facilities, and distribution areas where comfortable working conditions matter.
Maintains the temperatures commercial growing operations need through colder seasons and overnight conditions.
Comfortable, even heat across larger floors in shops, garages, barns, and commercial buildings.
Supports heating needs for pools, hot tubs, and other recreational water applications.
Provides hot water for homes, agricultural buildings, commercial facilities, and other properties with significant demand.
Keeps large garages, workshops, and workspaces warm without bringing the furnace or combustion indoors.
Heats larger buildings and multiple spaces through existing or new forced-air systems.
Sustained heat for wood-drying operations, kilns, and other processes where controlled heat matters.
The Bio950 boiler pairs with an AF-15 automated fuel bin.

Additional Details
A commercial-grade, automated biomass boiler built for larger commercial and industrial spaces. The Bio950 provides up to 950,000 BTUs and is designed to heat roughly 20,000 to 32,000 square feet.
It is a multi-fuel system designed to burn wood chips, pellets, and other compatible biomass fuels without requiring adjustments between fuel types.
The system automatically feeds fuel from the hopper into the boiler. Combustion heat passes through the water-filled triple-pass heat exchanger, and the heated water is circulated to the building or buildings being heated.
The automated fuel hopper is built for extended burn times, letting the system run for days or even weeks without refueling, depending on the fuel used and heating demand.
Yes. The Biomass Series can distribute heat to multiple buildings — a Crown Royal Stoves dealer can help determine the right setup for your application.
Accessible cleanout doors and large removable ash pans make routine cleaning and ash removal straightforward.
The Biomass Series is built for larger commercial and industrial applications. For a smaller-scale automated residential option, see the Flex Series.
