  • Product Overview

    Designed for use with your existing HVAC duct work, the US Stove 8500 Multi-Fuel Furnace works independently or in conjunction with your existing furnace. Burning wood pellets, corn, and other compressed biomass fuels, the 8500 uses 2 blowers and up to 105,000 BTUs to distribute heat in homes up to 2,800 square feet. This eco-friendly heating system also offers digital controls, multiple modes, and various safety features.

    Powerful Heating

    The US Stove 8500 can hold 320 pounds of fuel for an extended burn time. Twin 800 cubic feet per minute (CFM) blowers and 105,000 BTUs of power evenly distribute large amounts of heat into your space. As the fuel burns, this model’s blowers insert warm air into your HVAC system, which carries the air around your home.

    Digital Control Board

    Located on the lower left-hand side of your furnace, the digital control board makes it easy to turn this model on and off or make adjustments. This is also select automatic or manual mode. Automatic mode uses pre-selected settings to apply heat; while manual mode lets you make adjustments to your various heating options.

    For example, change the amount of fuel being delivered to the burnpot area by pressing the Heat Range buttons up and down. The more fuel that’s in the burnpot, the more hot air will be produced by the US Stove 8500.

    Additional Features

    • EPA Certified: The US Stove 8500 Furnace is EPA compliant.
    • Removable Firebox: A large firebox can be removed for easy cleaning and ash removal.
    • Side Outlet Vent: This location makes it easy to vent your furnace through a wall.
    • Use as Standalone: Although this model is built to be used through your HVAC system, you can use it as a standalone unit if you prefer (but heat won’t be distributed as effectively using this set up).
    • Integrated Agitator: This new agitator allows the furnace to burn different fuels.
    • Safety Features: Temperature control prevents overheating, and a pressure switch ensures proper operating conditions before feeding fuel into the burnpot.
    • Add Filtration: Add a Universal Filter Box, which attaches to this furnace’s blowers, to catch any unwanted particles from entering your indoor air.


    The US Stove 8500 Furnace is a powerful, versatile heating option that you can set up through your existing HVAC system to heat homes as large as 2,800 square feet.

    What Customers Love

    • Digital Controls: Simply press a button to start the heating process, adjust the heat level, or change modes.
    • Power: Two blowers distribute warm air throughout your entire home using the HVAC system.
    • Natural Heating: This model heats large spaces by burning natural resources, which makes it an eco-friendly choice. 

    Things to Consider

    • Installation: Additional installation materials have to be purchased locally, and a technician has to install the US Stove 8500 if you’re ducting it through your HVAC (which is suggested).
    • Regulations: Be sure to contact your building or fire officials about permits, restrictions, and conditions. Remember to observe all clearance to walls/combustibles as well.
