Massive rocket furnaces construction workshop

-

Rocket furnaces are known for their efficiency and simplicity of construction process. Since they develop an extremely high temperature in the firebox, almost all the energy contained in the firewood is converted into heat (efficiency over 90%, unlike classic stoves which at best achieve 70% efficiency). The distinctive feature of such furnaces is the large thermal mass that serves as a heat accumulator, and can be shaped in accordance with the interior design.
