StoveTec’s Big Foot Two-Door Deluxe Rocket Stove can burn wood, charcoal, or biomass and is our most popular rocket stove model. The Two-Door Deluxe is an excellent option for cooks wanting multiple fuel-use capabilities while still utilizing StoveTec’s efficient design and rugged durability. The Two-Door Deluxe is extremely popular among emergency preparedness enthusiasts and campers alike. Features include a rugged double kiln-fired ceramic combustion chamber with a 3.9 inch diameter chimney section that enables smoke and emissions to mix with the flame, decreasing harmful emissions and virtually eliminating any smoke. StoveTec also added a refractory FeCrAl alloy liner to the inside of the combustion chamber to help protect the ceramic insulation, increasing the life of your stove, facilitating easier cleanup, and providing additional refractory insulation. Both the main combustion chamber door (includes upgraded refractory metal insert) and the lower damper door have reinforced metal frames with easy swing hinges to help regulate optimum airflow.
