## Long description

Harvia AC3000 sauna stones, a 20 kg pack of grey olivine diabase stones, are designed as an accessory for both electric and wood-fired sauna stoves. Mined from subvolcanic deposits in Western Finland, these traditional angular stones have a dense structure that stores and releases heat evenly. Sized 5–10 cm and delivered in a compact box (290×400×150 mm), the stones support efficient steam production when water is ladled onto the heater and help maintain a stable sauna temperature.
Advantages
The Harvia AC3000 stones provide excellent heat storage capacity and thermal conductivity thanks to their high density. Their split-face surfaces vaporise water effectively, producing consistent steam, while the angular shape makes stacking simple and promotes good air circulation within the heater. The dark grey olivine diabase material is durable under repeated heating cycles and does not contain harmful ingredients.
Suitable for
 Electric sauna heaters needing replacement or additional stones
 Wood-fired sauna stoves used as top stones for improved steam
 Public and private saunas requiring durable, high-density stones
 Situations where efficient steam production and stable temperature are desired

How to use
Place the Harvia AC3000 stones according to your heater manufacturer's instructions. For electric heaters, stack the stones to allow air flow between them and avoid blocking heating elements. For wood-fired stoves, use the stones as top stones to support steam generation. Before first use, inspect stones for dust or fragments and rinse if necessary. Replace cracked or crumbling stones to maintain heater efficiency and safety.
Usage recommendations
Always follow the sauna heater manufacturer's guidelines for stone type, quantity, and placement. Allow stones to heat gradually after installation and avoid pouring large amounts of water at once; use moderate ladles to produce steady steam and protect the stones from thermal shock. Replace stones that show significant cracking or powdering to ensure consistent heat retention and safe operation.
