HUUM Steel Electric Sauna Heater 9 kW
The HUUM Steel is an enhanced version of the HUUM Steel Mini, available in 6 kW, 9 kW, and 10.5 kW models. Staying true to HUUM’s commitment to large stone capacity, it holds up to 10 boxes of stones, each weighing 33 lbs (approximately 330 lbs or 150 kg total). This significant stone volume ensures excellent steam production and even heat distribution, leveraging the heater’s substantial thermal mass. With a sleek and slim design requiring minimal safety distances, the HUUM Steel is perfect for saunas with limited space, offering a modern, rectangular shape distinct from the oval or circular profiles of the Hive and Hive Mini models.
One key feature that sets the HUUM Steel apart from models like the Hive Mini or Drop is its integrated air tunnel. This innovative design fully encloses the heating elements, providing exceptional protection and enhancing airflow. The improved airflow optimizes the heater’s performance, significantly reducing heating times. Both the HUUM Steel and HUUM Cliff benefit from this air tunnel feature, establishing them as technical standouts in the HUUM lineup.
As with all HUUM heaters, the Steel model seamlessly blends aesthetic sophistication with practical functionality. Features like WiFi control, a large stone capacity for extended steam sessions, and a maximum temperature of 110°C make it an excellent choice for those seeking a high-performance, efficient, and stylish sauna heater. The unique air tunnel system further solidifies the HUUM Steel’s reputation for innovation and superior design.
