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.

• Large stone capacity: Holds up to 330 lbs (150 kg) of stones, plus 35–40 kg in optional stone cage
• Efficient wood usage: One fire provides four sessions versus three in standard heaters
• Mild and long-lasting steam: Enjoy over 30 minutes of steam after the fire goes out
• Safe installation: Reduced safety clearance of only 150 mm from combustibles
