HUUM CLIFF Mini 10.5 kW Compact Wall-Mounted Electric Sauna Heater

The HUUM Cliff is a slim, floor-standing electric sauna heater designed for medium to larger indoor saunas, offering strong output in a compact, modern form. Available in 6 kW, 9 kW, and 10.5 kW versions, it builds on the concept of the Cliff Mini while providing greater capacity for larger spaces—without losing HUUM’s clean design language.

At the core of the Cliff’s performance is HUUM’s integrated air tunnel system, a feature shared with the HUUM Steel. This internal structure fully surrounds the heating elements, protecting them while directing airflow evenly through the heater. Improved airflow allows the Cliff to heat more quickly and operate with greater efficiency, while also supporting long-term durability.

Rather than relying on exposed metal surfaces, the Cliff emphasizes stone-based heat. With room for approximately 75 kg (165 lb) of sauna stones, it offers enough thermal mass to maintain stable temperatures and generate smooth, consistent steam. This balance of airflow and stone volume helps create a comfortable sauna environment with steady heat and well-controlled humidity.

From a design standpoint, the Cliff’s tall, narrow profile makes it well suited for saunas where floor space is limited. Its vertical form and restrained detailing give it a distinct presence without overwhelming the room. By combining efficient engineering, substantial stone capacity, and understated Nordic styling, the HUUM Cliff delivers a practical and refined sauna heating solution focused on both performance and aesthetics.
