HUUM CLIFF Sauna Heater

Product Overview

The HUUM CLIFF Sauna Heater is a slim, high-performance electric heater designed for sauna rooms from 8–13 m³ (283–460 cu. ft.). Featuring a 75 kg (165 lb) stone capacity and an integrated air tunnel for improved airflow, it delivers fast heat-up times and soft, consistent steam. With its compact design and modern aesthetic, it is an ideal choice for sauna spaces where efficiency and clean design are equally important.

The HUUM Cliff, an upgraded version of the HUUM Cliff Mini, is available in 6 kW, 9 kW, and 10.5 kW options, offering flexibility for a wide range of sauna sizes. It shares key innovations with the HUUM Steel, particularly the integrated air tunnel that fully encloses the heating elements. This design enhances airflow, improves efficiency, and significantly reduces heat-up time.

Like the HUUM Steel, the CLIFF combines a generous stone capacity with excellent airflow to produce consistent heat and high-quality steam. While it holds slightly fewer stones than the Steel, its 75 kg (165 lb) capacity still provides substantial thermal mass for a smooth and enjoyable sauna experience.

With its slim vertical design and refined aesthetic, the HUUM CLIFF is well-suited for sauna layouts where space efficiency is important. It delivers the core benefits of HUUM heaters—soft heat, strong steam performance, and modern design—making it both a functional and visually appealing addition to any sauna.
