Harvia AC3020 Olivine Diabase Sauna Heater Stones — Split Face, 10-15cm (4-6 inch). 44 lb box.

Mined from subvolcanic rock in Western Finland, the AC3020 stones are the correct stones for Harvia electric heaters in the Virta, AF Forte, M, Pro, and Legend series. Split-face angular stones are essential for electric heaters — they allow loose placement so heat can move efficiently between the elements and stones, and the broad fracture surface creates abundant, soft steam when water is poured over them.

Note: Each natural stone is unique. Purchasing one extra box is recommended to allow you to select the best stones for fit and placement.
