Technical stuff.
Each stove is constructed from high grade steel tubing, curved to form the cylindrical fire box. As most of the steel tube is within the burn chamber the heat from the fire warms the air rapidly. As the warmed air rises it draws cool air in beneath and so the cycle continues. The pipes and the claddings both help to give direction to the air flow encouraging the efficient convection.
