HUUM Hive Flow Wood-Burning Sauna Stove

The HUUM Hive Flow Wood-Burning Sauna Stove redefines efficiency and eco-friendliness in sauna heating. This stove’s design directs 75% of the firewood’s heat directly into the sauna, reducing heat loss through the chimney. As a result, you can enjoy up to four sessions using the same amount of wood that typically provides only three sessions. With its patent-pending technology, the Hive Flow minimizes environmental impact, producing only 346 mg/m³ of CO emissions (compared to over 1000 mg/m³ in similar stoves) and an exceptionally low 25 mg/m³ of particulate matter. Additionally, the Hive Flow’s unique construction allows for reduced safety clearances of just 150 mm from combustible surfaces, compared to the typical 200-500 mm required. This innovative design achieves a consistent and even warmth, allowing for a snug installation. Built with durability in mind, the Hive Flow’s structure includes a 5 mm thick top and 3 mm thick sides, ensuring balanced heat distribution and preventing any area from overheating. With a weight of 67 kg (73 kg for the LS model) and a stone capacity of up to 150 kg, plus an extra 35-40 kg in the stone cage, the Hive Flow delivers long-lasting, mild steam sessions. The substantial stone volume retains heat, allowing for more than 30 minutes of relaxing steam even after the fire has gone out. The stove’s large glass door creates a cozy, inviting ambiance in the sauna, offering a view of the flickering flames, much like a fireplace. The HUUM Hive Flow meets rigorous environmental standards, including Germany’s BImSchV Stufe 2 and the European Commission’s Regulation 2025/1185, ensuring a sauna heating experience that is both high-quality and sustainable. Choose the HUUM Hive Flow for an efficient, eco-friendly, and comforting sauna experience that supports both your well-being and the environment.+ Stove Power rating 9.8 kW Steam room min 8 m³ / 282 ft³ Steam room max 18 m³ / 635 ft³ Holding capacity of sauna rocks ~150 kg / 330 lb Weight 67 kg / 148 lb Height 884 mm / 34.8 in Width 526 mm / 20.7 in Depth 586 mm / 23.1 in Firewood length 300 mm / 11.8 in Diameter of the flue 114 mm / 4.5 in
