How would you like to make the world's most efficient stove? This rocket mass heater uses a wood-burning stove with a combustion chamber to store and radiate heat. Since it produces high heat with low emissions, it is ideal for sustainable heating. See how the majority of this heater is made with dirt! This video is a DIY tutorial covering every step in detail: learn how to plan the ductwork and layout, build the combustion chamber, insulate the heat riser, clamp the chimney to the roof, install the barrel and manifold, cob the outside and build the bench. This is so detailed that anyone could follow it and be successful.
