Harvia AC3020 Sauna Stones 10–15 cm, 20 kg
Ideal for wood-burning heaters. Buy Harvia AC3020 large split olivine diabase sauna stones (10–15 cm, 20 kg) for heavy-duty stoves.
The Harvia AC3020 sauna stones are large, split-face blocks made of premium-grade olivine diabase. Known for its excellent thermal mass and shock resistance, this stone type is engineered to endure intense, direct fire contact. Featuring a heavy-duty size fraction of 10–15 cm, these stones are ideal for the bottom layer of wood-burning sauna heaters and large commercial electric units.
The large, irregular shapes allow for generous gaps between the stones, ensuring the perfect amount of draft and airflow needed for wood stoves to operate efficiently. This open structure protects the inner metal housing of the heater from warping while distributing high heat evenly throughout the room. Harvia stones are highly durable, soot-resistant, and entirely free from harmful mineral fibers or odors.
