The Bio-Burner – BB-500

The Bio-Burner BB-500 is a multi-fuel biomass heating system and BioChar maker that can be attached to any existing climate control unit. BB-500 has up to 500,000BTU output, automated computer controls, highly efficient and clean burn, and passed safety standards for indoor and outdoor use.


What is the Bio-Burner BB-500?

The Bio-Burner BB-500 is a multi-fuel biomass heating system and BioChar maker with up to a 500,000BTU output which will heat an average of 25,000 square feet (depending on insulation efficiency of structures being heated). It is a wood chip boiler, sawdust boiler, pellet boiler, solid fuel boiler, and more. It’s the perfect solution for burning horse manure in barns, heating greenhouses (approximately 5,000 square feet), and other light industrial applications. It is designed to burn inexpensive and locally available biomass waste as fuel for heat and to create high-quality BioChar (>75% carbon). The BB-500 has multiple fuel bin options and is safety rated for indoor and outdoor use. Its intuitive automated computer controls coordinate temperature monitoring, fuel input and air injection speed, fuel ignition and re-light, automatic gas backup option, and ash removal to create the cleanest and most efficient burn.

Why is the Bio-Burner the best multi-fuel biomass boiler?

The Bio-Burner is unique as a solid fuel boiler as it burns many types of biomass fuels with days or even weeks of run time between fuel bin refills and requires only software adjustments when changing fuel types. It has automatic gas backup for when fuel bin is empty. The emissions from the Bio-Burner are extremely clean due to precise controls and unique technology which completely burns fuel in a single pass and has automated settings that turn the Bio-Burner into a continual-feed BioChar maker. You will never see creosote buildup and you’ll never see a single spark escape through the exhaust. Maintenance is easy because of the zero-creosote burn and automated ash removal. The Bio-Burner is a hydronic heater and is meant to be coupled with an existing heat exchanger or heat distribution system such as radiant heat or forced air heat.

How does the Bio-Burner work and what can I burn?

The Bio-Burner is designed for burning biomass such as wood chips, sawdust, pellets, horse manure, animal bedding, and more. (See complete list of approved fuels here.) Fuel is automatically metered into burn chamber and ignited via natural gas or propane. Once temperature is achieved the gas shuts off and temperature is maintained with biomass fuel only. Hot air exits the burn chamber and runs through decoupled water heat exchanger. Once water is heated, the hot water is delivered to connected climate control unit to provide heat for applications such as domestic hot water, radiant heat, or forced air heat.
