The Sedore Furnace/Boiler burns environmentally clean with high heating efficiency for fifteen hours on just one load of wood or corn and up to 24 hours on pellets and cubes. The fact that there is no firebrick in this Furnace/Boiler means that the heat radiates out of the Furnace/Boiler and into the room instead of being lost up the chimney. High efficiency heating means that it burns less fuel for the same amount of heat, and therefore fewer trees are cut. Environmentally clean combustion means that the fire is burning all the gases etc., in the Furnace/Boiler, giving you extra heat and leaving little exhaust to clog the chimney and pollute the environment.
To produce a Furnace/Boiler that will last for decades while producing a maximum amount of heat from wood and other biomass fuels.
