KALVIS K-PR5-S 12kW sauna stove

KALVIS K-PR5-S is a wood-burning sauna stove with a nominal heat output of 12 kW, designed for sauna rooms with a volume of approximately 12–20 m³. Its construction is designed to accommodate a large quantity of stones for stable heat accumulation and distribution.

The recommended stone quantity is 150 kg. The large stone capacity helps accumulate heat and provide a stable and long-lasting heat output inside the sauna. The stove body is manufactured from 4–6 mm steel plate.

The K-PR5-S is fired from outside the steam room, allowing firewood loading and ash handling to take place in the adjoining room. The firebox door is equipped with ceramic glass, providing a view of the flame.

The fuel-loading chamber has a volume of 40 litres, the maximum log length is 33 cm, and the maximum permissible fuel-load weight 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 construction allows a water-heating tank to be installed on the stove. The K-PR5-S itself does not have an integrated water-heating chamber.
