Huum HIVE Flow Efficient Wood Burning Sauna Stove 

The HUUM Hive Flow Wood-Burning Sauna Heater Stove combines efficiency, sustainability, and aesthetic appeal for a truly immersive sauna experience. The HUUM HIVE Flow Sauna Stove has an innovative design, ensuring that 75% of the heat from the firewood directly heats your sauna rather than escaping through the chimney.With 75% of the firewood's heat directed to your sauna, this design provides an extra session with the same amount of wood, saving both energy and resources.

Environmentally conscious, the Hive Flow emits just 346 mg/m³ of CO and 25 mg/m³ of particulates, setting a high standard for eco-friendly heating. Its patented design allows for safe installation just 150 mm from combustible materials, making it perfect for compact sauna spaces.

Built to last, the Hive Flow 8.5kW can hold up to 231 lb of stones, and the 9.8kW can hold up to 330lb, ensuring gentle, enduring warmth even after the fire is out. The large glass door adds a warm, inviting glow, creating a cozy fireplace effect.

Meeting German and EU environmental standards, the Hive Flow also offers an LS model for heating from an adjacent room. Available in Mini and Mini LS versions, it’s a flexible, sustainable choice for your sauna.

Made with care in Estonia

HUUM heaters are made of stainless steel and go through a long and carefully supervised production process to guarantee the best quality of each product.

Steam like in a traditional sauna

HUUM heaters are built by using very small amounts of metal so that the heat comes mainly from the stones and only very little from the metal. This way we can maximize the good negative ions from the stones, like in traditional saunas, and keep the positive ions from the metal at a minimum. Together with a high stone capacity this is our secret to healthy, mild and long-lasting steam.

Sauna in Estonian tradition – a cleansing and healing holy place
