Product Overview
The HUUM Steel Sauna Heater is a slim, high-performance electric heater designed for sauna rooms from 10–16 m³ (354–566 cu. ft.). Featuring a large 150 kg (331 lb) stone capacity and an integrated air tunnel for improved airflow, it delivers fast heat-up times, soft, consistent steam, and excellent heat retention. With its compact, space-saving design and compatibility with HUUM’s smart controls, it is an ideal solution for both residential and commercial sauna environments.
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 up to 10 boxes of stones. This substantial thermal mass ensures abundant steam production and even heat distribution, creating a balanced and enjoyable sauna experience.
A distinctive feature of the HUUM Steel is its integrated air tunnel, which fully encloses the heating elements to provide enhanced protection and significantly improved airflow. This design increases heating efficiency and reduces heat-up times. Shared with the HUUM Cliff series, this feature positions the Steel as one of the most technically advanced heaters in the HUUM lineup.
With its sleek rectangular form, minimal safety distances, and modern aesthetic, the HUUM Steel is particularly well-suited for sauna layouts where space is limited. Like all HUUM heaters, it combines refined design with practical functionality, including WiFi control compatibility, high stone capacity, and a maximum temperature of 110°C (230°F) for a premium sauna experience.
