Harvia AC3020 Olivie Diabase Sauna Stones 10-15cm (10 Pack)

Harvia AC3020 Olivie Diabase Sauna Stones

Only available with the purchase of a Harvia sauna heater or stove.

Genuine Harvia AC3020 sauna stones are crafted from olivie diabase, selected according to traditional Finnish sauna standards. These split-face stones deliver optimal heat retention and steam generation for authentic sauna experiences. Each pack contains 10 stones ranging from 4 to 6 inches (10-15 cm), specifically sized for proper heat circulation and longevity of your sauna heater.

Split-Face Design for Superior Performance

The split-face construction of these diabase stones is engineered for electric heaters and woodburning stoves. The wide fracture surfaces allow water to evaporate efficiently, creating soft, consistent steam. Angular edges enable loose placement between heating elements, ensuring proper air circulation throughout the stone chamber. This airflow is critical for extending the lifespan of electric heating elements and maintaining consistent sauna temperatures.

High-Heat Capacity Olivie Diabase

Olivie diabase is selected for its exceptional durability and heat storage properties. These stones withstand repeated heating and cooling cycles without cracking or deteriorating. The high-heat capacity means they store thermal energy efficiently and release it gradually, maintaining stable sauna temperatures and reducing energy consumption.

Compatible Harvia Sauna Heaters

The AC3020 stones are designed for the following Harvia sauna heater series:

• Virta Series
• AF (Forte) Series

Proper Stone Placement

Correct stone placement is essential for sauna heater performance. The angular shape of these split-face stones allows for loose stacking, creating air gaps between stones and heating elements. This spacing prevents overheating of electrical components and ensures even heat distribution throughout the sauna. Replace stones when they show signs of crumbling or significant wear to maintain optimal performance.
