Huum Hive Flow - Wood Sauna Heater

Made in Estonia: The pure Nordic design of the Huum Hive Flow is inspired by nature and showcases a premium European product. HUUM collaborate with leading Estonian metal processors who ensure the highest quality at each production stage.

Standard and LS models available: The HIVE Flow is available in both standard and LS (Long Side) configurations. The standard model is loaded from within the sauna, while the LS model features an extended firebox that allows firewood to be loaded from an adjoining room, helping keep the sauna cleaner and reducing the need to open the sauna door during operation.

High-performance materials: Built for demanding sauna environments, the HIVE Flow features a robust steel construction with a 5 mm thick top plate and 3 mm thick side walls. The heavy-duty design promotes even heat distribution and is engineered for long-term reliability.

Large stone capacity: Available with stone capacities of up to 150 kg, plus an additional stone cage capacity, the HIVE Flow delivers soft, gentle and long-lasting steam. The substantial thermal mass stores heat efficiently and continues producing enjoyable sauna conditions long after the fire has subsided.

Long-lasting heat: The large stone volume retains heat exceptionally well, allowing the sauna to remain warm and producing steam for more than 30 minutes after the fire has gone out. This creates a comfortable and consistent sauna experience without the need for constant fire management.

Clean combustion: Designed to meet stringent European environmental standards, the HIVE Flow is one of the cleanest-burning wood-fired sauna heaters available. Advanced combustion technology significantly reduces smoke, particulate matter and carbon monoxide emissions compared to conventional wood-burning sauna heaters.

Exceptional efficiency: The HIVE Flow features an innovative internal airflow design that directs up to 75% of the heat generated by the fire into the sauna rather than allowing it to escape through the flue. This maximises heat output from every piece of firewood while reducing fuel consumption.

Safer installation: The innovative firebox and airflow design help reduce heat loss to surrounding structures, allowing for smaller safety clearances compared with many traditional wood-fired sauna heaters. This can provide greater flexibility when designing and building a sauna.

Setup: The HUUM HIVE Flow is a floor-mounted wood-fired sauna heater suitable for a wide range of residential and commercial sauna projects. It is available in standard and LS (through-wall firebox) models, allowing firewood to be loaded either from within the sauna or from an adjoining room.
