HUUM HIVE Flow 9.8kW LS | Wood-Burning Sauna Stove

The HUUM HIVE Flow 9.8kW LS is the through-the-wall version of the HIVE Flow wood-burning sauna stove. Its extended firebox passes through a non-combustible wall, so the fire is lit and fed from the adjacent room or from outside while the stove body and stones stay in the sauna. Wood, ash and smoke stay out of the hot room, and the sauna stays clean and quiet while the fire is tended.

Rated at 9.8 kW for sauna rooms of 282–635 cubic feet, the Flow LS directs 75% of its heat into the sauna and holds up to 330 lbs of stones for long, even steam that continues for 30+ minutes after the fire dies down. It is built from stainless steel with a 5 mm top and 3 mm sides, takes 11.8" logs through a large glass door and has low CO emissions (346 mg/m³). The firebox is 4.7" longer than the standard HIVE Flow and fits walls up to 4" thick, or up to 6" with a HUUM mounting collar.
