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

KALVIS K-KO2 is a wood-burning air heater-cooker with a nominal output of 14.5 kW, designed for both space heating and cooking. KALVIS positions this model particularly for buildings without a central heating system, such as summer houses, country homes, workshops and other smaller premises.

Its compact construction allows installation even in relatively small rooms. The upper section incorporates a cast-iron cooking plate with rings, allowing the appliance to be used for cooking and heating food. A wide firebox door makes loading wood easier.

The fuel chamber has a volume of 40 litres and accommodates wood logs up to 40 cm long. A single fuel load can burn for up to 5 hours, although actual burn time depends on fuel type, moisture content, outdoor temperature and other operating conditions.

The primary fuel is wood logs. Wood waste, peat briquettes and sawdust briquettes may also be used as substitute fuels. KALVIS does not recommend burning firewood with moisture content exceeding 25%.

The K-KO2 is equipped with outlets for connecting hot-air ducts, allowing heated air to be distributed to other rooms. With sufficient chimney draught, the manufacturer also provides the possibility of connecting the appliance to a heating wall. The armrest can be installed on either side of the appliance.
