The HUUM Hive Flow Mini LS Wood-Fired Sauna Heater<\/strong> is engineered for exceptional efficiency and low environmental impact, redefining what a modern wood-fired sauna heater can achieve. Its advanced combustion system directs approximately 75% of the heat from the firewood straight into the sauna<\/strong>, rather than losing it through the chimney. In practical terms, this allows you to enjoy four sauna sessions using the same amount of wood typically required for three<\/strong>.<\/p>\n

At the core of the HIVE Flow\u2019s performance is HUUM\u2019s patent-pending airflow and combustion design<\/strong>, which significantly reduces emissions. Carbon monoxide output is limited to 346 mg\/m\u00b3<\/strong>, far below the 1,000+ mg\/m\u00b3 common in comparable wood stoves, while particulate emissions are just 25 mg\/m\u00b3<\/strong>, among the lowest in its class. This efficiency also enables short safety clearances of only 150 mm<\/strong> from combustible materials\u2014considerably less than the standard 200\u2013500 mm\u2014making the stove easier to integrate into compact sauna layouts.<\/p>\n

Built for durability and consistent heat delivery, the stove features a 5 mm thick top plate and 3 mm thick steel sides<\/strong>, ensuring even heat distribution and preventing localized overheating. The HIVE Flow Mini LS weighs 73 kg<\/strong> and accommodates up to 150 kg of stones<\/strong>, with an additional 35\u201340 kg<\/strong> supported by the external stone cage. This substantial stone mass stores heat efficiently, allowing for soft, lingering steam for more than 30 minutes after the fire has burned out<\/strong>.<\/p>\n

The experience is enhanced by a large glass furnace door<\/strong>, which brings warmth and visual comfort to the sauna by showcasing the natural movement of the flames\u2014creating an atmosphere similar to a small fireplace.<\/p>\n

The HIVE Flow Mini LS fully complies with Germany\u2019s BImSchV Stufe 2 environmental standard<\/strong> and European Commission Regulation 2025\/1185 for solid fuel local space heaters<\/strong>, exceeding current efficiency and emissions requirements. This makes it a responsible, long-term choice for sauna owners who value both performance and sustainability.<\/p>\n

The LS (loading side) configuration<\/strong> allows the stove to be fired from an adjacent room, keeping the sauna space clean while improving convenience and safety.<\/p>\n

Additional configurations<\/strong> are available, including the HIVE Flow Mini<\/strong> and Mini LS<\/strong>, weighing 54 kg and 59 kg<\/strong> respectively and holding 105 kg of stones<\/strong>. With the optional stone cage, these models can support up to 40 kg<\/strong> of additional stones.<\/p>\n
