HUUM Wood Stoves Overview
HUUM wood stoves bring real-flame ritual together with modern design and generous stone mass. The HIVE Flow and Flow Mini are slim tower stoves that fit tight footprints and move air efficiently while carrying enough stones for soft, even löyly. The HIVE Wood 13 and 17 use a classic round basket with very high stone capacity for the gentlest steam and stable temperatures in small to large rooms. LS variants of Flow and 17 shift the loading door through the wall so you can fuel from an adjacent room, keeping the hot side cleaner and quieter. Across the lineup you can match profile, firebox size, and loading style to your space and the way you like to sauna.
Technical Details
HUUM wood stoves are sized by room volume and build quality. Larger fireboxes and more stone mass match larger or colder rooms. These units have no electric heating elements. The flue connects to a compatible chimney system as specified in each manual.

Sizing Guidance
- Calculate your room volume in cubic feet.
- Adjust for cold surfaces such as glass, tile, and stone to maintain warm-up speed and steam quality.
- Consider insulation for outdoor cabins.
- If you are between models, choose the larger firebox for faster heat-up and better recovery between water ladling.
