The Huum Hive Flow is a 9.8kW wood burning sauna stove designed and built in Estonia. The stone clad body radiates heat from every surface rather than just the top, and the internal flow design moves heat through the stone mass evenly, so the room warms without a hot zone directly above the firebox.
It is efficient on fuel for its output, and meets the German BImSchV emissions standard, which is one of the stricter European requirements for solid fuel appliances. A glass firebox door keeps the fire visible while the stove runs.
