KALVIS K-KO2 14kW air heating boiler-stove, RAL1014

KALVIS K-KO2 is a compact wood-burning air heater-cooker designed for both space heating and cooking. According to the official KALVIS technical table, its nominal output is 14.5 kW, with a stated heated area of 40–90 m².

The K-KO2 combines heating and cooking functions in one appliance. Its compact construction makes it suitable for smaller rooms, while the wide firebox door makes loading wood easier.

A cast-iron cooking plate with rings is installed on top of the appliance. The K-KO2 also has outlets for connecting hot-air ducts, allowing heated air to be distributed to other rooms. With sufficient chimney draught, it can also be connected to a heating wall. The armrest can be installed on either side.

The fuel chamber has a capacity of 40 litres and accepts logs up to 40 cm long. One fuel load can burn for up to 5 hours, depending on fuel type, moisture content, outdoor temperature and other operating conditions.

The main fuel is wood logs. Wood waste, peat briquettes and sawdust briquettes may also be used. KALVIS does not recommend wood with a moisture content exceeding 25%.
