HUUM STEEL Electric Sauna Heater 10.5 kW

The HUUM Steel, an upscaled variant of the HUUM Steel Mini, is available in 6 kW, 9 kW, and 10.5 kW capacities. It upholds the HUUM hallmark of a large stone capacity, accommodating 10 boxes of stones, each weighing 33 lbs (approximately 331 lbs or 150 kg in total). This significant stone volume ensures abundant steam production and uniform heat distribution due to the extensive thermal mass. Designed with slim aesthetics and notably small safety distances, the HUUM Steel is ideally suited for saunas where space is at a premium, offering a modern, square, more rectangular shape compared to the oval and circular designs of the Hive and Hive Mini models.

A distinctive feature setting the HUUM Steel apart from models like the Hive Mini or the Drop is its integrated air tunnel. This design not only covers but exceeds the full extent of the heating elements, offering unparalleled protection and promoting airflow around them. This airflow enhances the heater’s efficiency, reducing heating time significantly. Both the HUUM Steel and the HUUM Cliff are distinguished by this air tunnel feature, positioning them as technically superior within the range.

Like all HUUM heaters, the Steel model combines aesthetic appeal with functional excellence, including options for WiFi control, a substantial stone capacity for prolonged steam generation, and a maximum temperature reach of 110°C. This blend of features, along with the unique air tunnel system, makes the HUUM Steel a compelling choice for those seeking efficiency, design, and performance in their sauna heating solution.
