The HUUM HIVE Flow Mini is a premium wood-burning sauna stove engineered for exceptional efficiency and smooth, long-lasting steam. Its innovative firebox design directs roughly 75% of the heat from the firewood into the sauna instead of sending it up the chimney, making it one of the most efficient and environmentally sustainable wood heaters in its class.
Why It’s Worth It
- High-efficiency heating: engineered so most heat stays in the sauna (not the chimney)
- Rich steam (löyly): large stone mass supports softer, longer-lasting steam
- Compact footprint: premium performance for smaller sauna rooms
- Flexible venting: flue connection options at the top or back
- Made in Estonia: designed, engineered, and manufactured by HUUM
