The Rocket Stove

 

A rocket stove mass heater or rocket mass heater, is an innovative and efficient space heating system developed from the rocket stove, a type of hyper-efficient wood-burning stove, named in the 70’s, but dating back millenia in concept, and the masonry heater. Wood is gravity fed into a ‘J shaped’ combustion chamber, from where the hot gases enter a heavily insulated metal or fire-brick vertical secondary combustion chamber, the exhaust from which then passes along horizontal metal ducting embedded within a massive cob thermal store. The thermal store is large enough to retain heat for many hours and typically forms part of the structure of the building. They have proved to be popular with natural buildings and within permaculture designs; they are normally self-built and are not yet recognized by all building codes which regulate the design and construction of heating systems within buildings. via
