HUUM HIVE Flow LS – this is an improved HIVE Flow version with an external firebox, allowing it to be fired from another room. Due to the patented construction, as much as 75 % of the heat emitted by the firewood is used directly for heating the sauna, instead of being lost through the chimney, thus ensuring efficient energy use and a lower environmental impact.
A large amount of stones (150 kg) ensures long-lasting, gentle steam even after the fire has gone out.
Advantages:
- Ecology: extremely low CO emissions (~346 mg/m³) and particulate matter concentration (~25 mg/m³) – among the best in this segment.
- Safety: the patented construction allows installation closer, only 150 mm from combustible surfaces.
- Durable construction: the top is 5 mm thick, the sides – 3 mm, even heat distribution.
- Long-lasting steam: the stones retain heat and steam spreads even 30 minutes after the stove has gone out.
Model differences:
- HIVE Flow – the main model, with an internal firebox, heats directly in the sauna, holds up to 150 kg of stones.
- HIVE Flow Mini – a more compact version for smaller saunas, holds up to 105 kg of stones
- HIVE Flow LS – a model with an external firebox, allows the stove to be fired from another room, holds up to 150 kg of stones.
