DESCRIPTION
The Harvia Sauna Heater Stones Split Face 10-15 cm Model AC3020 are selected according to traditional standards to deliver an authentic sauna experience with consistent, soft heat. Made from high-quality olivine diabase, these stones efficiently store heat and release it evenly, creating optimal steam when water is applied.
The split-face design provides a wide surface area for better evaporation and allows for loose placement of the stones. This is especially important in electric heaters, as it promotes proper airflow between the heating elements and stones, helping extend the lifespan of the heater while ensuring efficient heat distribution.
These stones are suitable for both electric sauna heaters and wood-burning stoves and are compatible with a wide range of Harvia heater series.
Compatible with:
Virta Series
AF (Forte) Series
M Series
Pro Series
Legend Series
CAUTION: Light (ceramic), soft (soapstone), and smooth (rounded) sauna stones do not produce the desired results and may cause issues, especially in electric heaters.
