The HUUM Cliff, an upgraded version of the HUUM Cliff Mini, is available in 6 kW, 9 kW, and 10.5 kW options, providing a versatile choice for those seeking a powerful sauna heater. It shares several key features with the HUUM Steel, particularly the innovative built-in air tunnel design. This air tunnel encases the heating elements entirely, offering full protection while enhancing airflow through the heater. The increased airflow accelerates heating, making the heater more efficient—a standout feature that sets HUUM heaters apart in the market.

Like the HUUM Steel, the HUUM Cliff is designed to combine a large stone capacity with excellent airflow, ensuring both a significant amount of steam and rapid heating. However, the Cliff model holds slightly fewer stones than the Steel, accommodating 5 boxes of rocks at 33 lb each, totaling approximately 165 lb (around 75 kg). This capacity, while slightly less than that of the Steel, still follows the principle of offering a substantial thermal mass for generating ample heat and steam.

The design of the HUUM Cliff also sets it apart, featuring slight variations from the Steel model that cater to different aesthetic preferences. Despite these differences, it retains the core advantages of HUUM heaters: a large stone capacity, the efficiency-enhancing built-in air tunnel, and a visually appealing design. This combination of features ensures that the HUUM Cliff is not just a functional sauna heater but also a beautiful addition to any sauna space, providing a perfect blend of form and function.
