HUUM HIVE Flow LS Wood Burning Sauna Stove















HUUM HIVE Flow Wood-Burning Sauna Stove
The HIVE Flow wood-burning stove by HUUM is one of the most efficient and environmentally sustainable sauna heaters available. Thanks to its innovative, patent-pending furnace construction, up to 75% of the firewood heat is retained in the sauna, minimizing waste through the chimney. This results in more heat, less wood consumption, and longer, milder steam sessions—perfect for both personal and commercial saunas.
