Larger Split-Face Stones for Heaters Specifying 10–15 cm Stones
The Harvia AC3020 split-face olivine diabase stones are sized at 10–15 cm (4–6 in.) for sauna heaters and wood-burning stoves that specify larger stones. The split-face cut exposes raw stone surfaces for contact with water when you ladle water for löyly. Each box contains 44 lbs of natural olivine diabase.
Product Overview
Olivine diabase is a durable, heat-stable stone used in sauna heaters. The AC3020’s larger size is intended for heaters that specifically require 10–15 cm stones, including select electric heaters and wood-burning stoves.
The split-face cut provides exposed surface area for water contact and steam generation. Stack loosely following your heater manufacturer’s guidelines to maintain proper airflow around the heating elements.
Note: Natural stone varies in shape, color, and texture. Stone dust may be present from shipping, so rinse stones before first use. Replace cracked or crumbling stones according to your heater manufacturer’s recommendations. Harvia recommends replacing sauna stones every 1–2 years, depending on frequency of use.
