Wood Burning Sauna Heater
HIVE FLOW & HIVE FLOW MINI
The Huum Hive Flow wood-burning heater stands out as one of the most efficient and environmentally sustainable sauna heaters on the market. Its innovative design ensures that 75% of the heat from the firewood directly heats your sauna rather than escaping through the chimney. The large volume of stones retains heat, providing steam for over 30 minutes after the fire is extinguished.
The Huum Hive Flow is the ideal choice for those who value environmental consciousness and wish to have a memorable sauna experience. The heaters CO emissions are just 346 mg/m3 compared to over 1000 mg/m3 in similar heaters, and the particulate matter output is only 25 mg/m3, the lowest in its category.
