Harvia AC3000 Sauna Stones 5–10 cm, 20 kg
Optimize your sauna steam production. Buy Harvia AC3000 split olivine diabase sauna stones (5–10 cm, 20 kg) for electric and wood heaters.
The Harvia AC3000 sauna stones are sourced from premium-grade, split olivine diabase rock, making them the most durable and reliable choice for both electric and wood-burning sauna heaters. Featuring a balanced size fraction of 5–10 cm, these stones are engineered specifically for smaller electric wall heaters or as the middle and top layers in larger heater chambers.
The angular, split-face surface maximizes heat retention and provides an expansive area for water evaporation, resulting in a soft, abundant, and rich steam production. The irregular shape allows for effortless, airy stacking, which is essential for ensuring excellent ventilation around heating elements. This prevents element burnout and increases the energy efficiency of your heater. Harvia stones are highly thermal-shock resistant, will not crumble over time, and do not emit any harmful substances or odors.
