Developed for people who value natural warmth, ecological responsibility, and architectural presence in equal measure.

Product feature – the HUUM HIVE Flow wood-burning sauna heater – internal and external firing as the heart of the sauna

The HUUM HIVE Flow wood-fired sauna heater – with internal and external firing – is one of the most efficient wood-fired sauna heaters in its class. Up to 75% of the energy contained in the firewood is used directly to heat the sauna cabin. The massive amount of stone stores the heat so effectively that gentle steam is still produced more than 30 minutes after the fire has gone out. The result is a uniform, deeply effective sauna climate with reduced wood consumption.

Design & materials – striking presence with the HUUM HIVE Flow wood-burning sauna heater – interior and exterior heating

The sculptural form of the HUUM HIVE Flow wood-fired sauna heater—with internal and external firing—is supported by a robust steel construction. A 5 mm thick top and 3 mm thick side walls ensure stability and even heat distribution. The large glass door opens up a view of the open fire and enhances the calm, pristine atmosphere in the sauna room. Thanks to the well-thought-out design, smaller safety distances are possible than with conventional wood-burning stoves.

Technology & functions – patented efficiency in the HUUM HIVE Flow wood-burning sauna heater – internal and external combustion

The HUUM HIVE Flow wood-burning sauna heater—with internal and external combustion—is designed for maximum efficiency and minimal emissions. With CO emissions of only 346 mg/m³ and particle emissions of 25 mg/m³, it significantly undercuts common comparative values. The large stone volume of up to 150 kg – supplemented by an additional 35–40 kg in the stone basket – generates particularly mild, long-lasting steam in the temperature range from 60 to 100 °C.

Application & comfort – flexible installation with the HUUM HIVE Flow wood-burning sauna heater – indoor and outdoor heating

The HUUM HIVE Flow wood-burning sauna heater – indoor and outdoor firing is available for both indoor and outdoor firing and is suitable for sauna cabins from 6 to 18 m³, depending on the model. The Mini and Mini LS versions hold around 105 kg of stones, while the larger models can hold up to 150 kg. The well-thought-out design reduces the risk of fire and allows for a comparatively compact installation with high performance.
