HUUM HIVE Flow LS Wood-Burning Sauna Stove

Experience the pinnacle of efficiency and sustainable design with the HUUM HIVE Flow LS. As one of the most environmentally conscious wood-burning heaters available today, the HIVE Flow LS represents a major breakthrough in sauna technology. Its innovative, patent-pending furnace construction ensures that 75% of the heat generated from your firewood goes directly into heating your sauna room, rather than escaping through the chimney. This exceptional efficiency means you can enjoy four sauna sessions using the same amount of wood typically required for three.

The LS model is specifically designed for convenience and cleanliness, featuring a firebox extension that allows you to heat your sauna from an adjacent room, keeping the sauna interior free of wood debris and smoke.

Eco-Conscious Performance

The HIVE Flow LS is engineered to minimize its environmental footprint without compromising on power. With CO emissions at just 346 mg/m³ (compared to over 1000 mg/m³ in standard stoves) and a particulate matter output of only 25 mg/m³, it boasts the lowest emissions in its category. It fully complies with the strict German BImSchV Stufe 2 environmental standards and European Commission Regulation 2025/1185, making it a responsible choice for the modern wellness enthusiast.

Innovative Heat Distribution & Safety

Thanks to its unique, patent-pending construction, the HIVE Flow warms up more evenly than traditional heaters. This uniform heat distribution allows for reduced safety distances of just 150mm (approx. 5.9") from combustible materials—significantly less than the 200-500mm usually required. This allows for a much snugger and more space-efficient installation. The stove is built for longevity with a robust 5mm thick top and 3mm thick side panels.

Exceptional Steam & Ambiance

With a massive stone capacity of 330 lbs (150 kg), the HIVE Flow LS provides a mild, soft, and long-lasting steam experience. The large volume of stones acts as a powerful thermal battery, retaining enough heat to provide steam for over 30 minutes after the fire has been extinguished. The large glass furnace door provides the cozy ambiance of a fireplace, allowing you to enjoy the mesmerizing dance of the flames while you relax.
