Why Choose the HUUM HIVE Flow Mini?

Efficient 8.5 kW Wood-Burning Performance

The HIVE Flow Mini uses natural firewood to generate traditional sauna warmth.

Its innovative, patent-pending combustion system is designed to transfer heat efficiently into the sauna room rather than losing unnecessary energy through the chimney.

HUUM reports that the HIVE Flow design directs approximately 75% of generated heat into the sauna environmentunder its specified testing conditions.

Actual heating performance depends on sauna construction, insulation, ventilation, chimney draft, and firewood quality.

Generous 231 lb Sauna Stone Capacity

Despite its compact dimensions, the HIVE Flow Mini accommodates approximately 105 kg (231 lb) of sauna stones.

The generous stone capacity helps retain heat and supports the soft, lasting steam associated with traditional Finnish and Estonian sauna bathing.

Carefully pouring water over properly heated stones creates bursts of steam, allowing you to personalize your sauna's humidity and atmosphere.

Beautiful Glass Firebox Door

A large glass firebox door provides a welcoming view of the flames, adding natural warmth and visual character to your sauna.

Enjoy the ambiance of a real wood fire while relaxing in a traditional sauna environment.

Compact, Contemporary Design

The HIVE Flow Mini combines an open steel frame with a modern, space-conscious silhouette.

Measuring approximately 17.7" wide × 19.4" deep × 34.8" high, the stove fits into appropriately designed smaller sauna rooms while still offering generous stone capacity.

Its elegant appearance complements both rustic and contemporary wood-paneled interiors.

Cleaner, More Efficient Combustion

HUUM's engineered combustion chamber is designed to support more complete wood burning and reduced emissions.

The HIVE Flow series is tested against applicable European efficiency and emissions requirements, including German BImSchV standards.

This makes the HIVE Flow Mini an appealing choice for sauna enthusiasts who appreciate efficient fuel use and thoughtful environmental engineering.

Convenient Removable Ash Drawer

The integrated ash drawer makes routine cleaning and maintenance easier.

Remove accumulated ash according to the manufacturer's instructions to support appropriate airflow and consistent stove operation.

Additional cleaning hatches provide access for routine maintenance.

Durable Steel Construction

Engineered for repeated high-temperature use, the HIVE Flow Mini incorporates durable steel components and a carefully designed combustion chamber.

Its construction balances long-term reliability, efficient heating, and contemporary design.
