size, beauty and efficiency of any of our Multi-Fuel stove's flame.

  • The patent pending burn technology has an agitator rod in the burn pot that breaks up any clinker or ash and is designed for burning grains and wood pellets.

    Unlike other stoves which will only burn clean grain or selective grains, the Maxx-M can burn barley, corn, oats, wheat, etc. right from the combine*.
    As of yet NUB has not tested the burning of faba beans, peas or rye.
    (If the grain is dry the stove should be capable of burning it.)
    *Straw can plug the auger.
