FIREBULL Mini convection stove, solid door, right-hinged door These are tubular convection wood-burning stoves for rapid room heating without a fan. The Mini model, with part numbers 2 to 6,5 kW, has a nominal heat output of 6,5 kW and is designed for rooms with a maximum volume of 120 m³.
This version features a solid door with right-hand hinges (viewed from the front). Solid steel doors ensure high durability and quiet operation, which is particularly advantageous in workshops, warehouses, and technical areas.
Suitable use
The FIREBULL Mini is particularly suitable for smaller workshops, garages, holiday homes, mobile businesses, and other confined spaces. The chosen output must be adjusted to the building’s heat loss, the ventilation method, the desired temperature, and the actual chimney draft.
This is how the stove works
The cooler air flows into the lower section of the tube casing, heats up around the combustion chamber, and exits back into the room through the upper tube sections via natural airflow. This design combines the radiant heat from the steel body with rapid convection and requires neither a fan nor electrical power.
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 an independent 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.
