FIREBULL S16 convection stove, solid door, left-hinged door, silver logo These are tubular convection wood-burning stoves for rapid room heating without an electric fan. The S16 model operates in the range of 16 to 37 kW, has a nominal output of 15,5 kW, and is designed for rooms with a maximum volume of 750 m³.
This version features a solid door with left-hand hinges (viewed from the front) and a silver logo. Solid steel doors ensure high durability and quiet operation, which is particularly advantageous in workshops, warehouses, and technical facilities.
Suitable use
The FIREBULL S16 is particularly suitable for large production halls, hangars, warehouses, and other demanding industrial spaces. The output level must be selected based on the building’s heat loss, the ventilation method, the required temperature, and the actual chimney draft.
This is how the stove works
The cooler air flows into the lower part of the pipe casing, warms in the tubes around the firebox, and exits back into the room through the upper part of the pipes via natural convection. The design thus combines the heat radiation of the steel body with rapid convection and requires neither a fan nor electrical energy for operation.
The dual-chamber combustion system utilizes regulated primary and secondary air. The heat exchanger tubes extend deep into the combustion chamber and, together with a robust deflector, contribute to heat transfer to the flowing air. The concept of tube convection stoves is based on the principle introduced by Eric Darnell in 1975; FIREBULL is a separate Czech product line.
Fuel and air supply
Use only dry wood with a maximum moisture content of approximately 20 %. The stove does not have a separate central external air supply, therefore sufficient combustion air must be ensured in the room. Installation and connection to the chimney must be inspected by a qualified professional.
