Description
The Huum Hive Flow LS is a 9.8kW wood-burning sauna stove with a firebox extension. The stove sits in the sauna while you load wood from the adjoining room, which keeps bark, ash, and cold drafts out and lets you tend the fire without interrupting a session.
Heat
The patent-pending furnace moves heat through the stone mass instead of sending it straight up the flue. It holds 330 lb of stones, which keep the room warm after the fire burns down and give a softer steam.

Before you buy: what to know
Based on the manufacturer's specs, manuals and our research.
- The Hive Flow LS is 9.8kW for rooms up to 635 cu ft, with a firebox extension so you tend the fire from the next room without interrupting a session.
- It holds 330 lb of stones, which keep the room warm after the fire burns down. It meets the German BImSchV emissions standard.
