KALVIS K-PR2-S 15kW sauna stove

KALVIS K-PR2-S is a wood-burning sauna stove with a nominal heat output of 15 kW, designed for sauna rooms with a volume of approximately 12–20 m³. Its construction is designed for fast heating and efficient sauna-room warming.

The stove body is manufactured from 4–8 mm steel plate, providing a robust and durable construction. The recommended quantity of sauna stones is 80 kg, allowing heat to be accumulated and released evenly into the steam room.

The K-PR2-S is fired from outside the steam room, allowing firewood loading and ash handling from the adjoining room. The firebox door is equipped with ceramic glass, providing a view of the flame. KALVIS officially offers the model in black RAL9005 and brown RAL8011.

The fuel chamber volume is 40 litres, the maximum log length is 35 cm, and the maximum permissible fuel load is 5 kg. The primary fuel is wood logs. Wood waste and sawdust briquettes may be used as backup fuels. Oak wood logs and coal are prohibited.

An important feature of the K-PR2-S is its integrated 4-litre water-heating chamber. According to KALVIS, the heat exchanger can be used for heating water in a tank with a volume of up to approximately 100 litres.
