KALVIS K-PR2-1 15kW sauna stove-fireplace
KALVIS K-PR2-1 is a wood-burning sauna stove-fireplace with a nominal heat output of 15 kW, designed for sauna rooms with a volume of approximately 12–20 m³. KALVIS highlights the model as a fast-heating sauna stove with an integrated water heat exchanger and fireplace-style panoramic door.
The stove body is made from 4–8 mm steel plate, providing a strong and durable construction. The recommended stone quantity is 80 kg, helping the appliance store heat and distribute it evenly throughout the sauna.
The K-PR2-1 is fired from outside the steam room, allowing wood loading and ash handling from the adjoining room. A key feature is the large firebox door with panoramic ceramic glass, providing a clear view of the flame and giving the stove a fireplace-like appearance. Protective wooden supports/armrests are also included in the design.
The fuel chamber volume is 40 litres, 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.
The K-PR2-1 has an integrated 4-litre water-heating chamber. According to KALVIS, the heat exchanger can be used to heat water in a tank with a capacity of up to approximately 100 litres. The model is officially available in black RAL9005 and brown RAL8011.
