FIREBULL Mini convection stove, glass door, right-hinged door These are tubular convection wood-burning stoves for rapid room heating without an electric fan. The Mini model operates in the 2 to 6,5 kW range, has a nominal output of 6,5 kW, and is designed for rooms with a maximum volume of 120 m³.
This version features a glass door with right-hand hinges (when viewed from the front). The glass door allows for visual monitoring of the fire and offers a pleasant view of the flames, making it suitable for clubhouses, restaurants, and social or leisure 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 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.
