A rocket stove mass heater is an innovative and efficient space heating system. Multiple small bells are effective in heat extraction than a single big bell, the total volume can be smaller too. They can be arranged in many ways, at the side or on top of another. The top arrangement is used to place a baking oven in one of them. The following simulation is a double-bell model designed by Martin Karl Waldenburg from Germany.
