HUUM STEEL 9kW 240V Electric Sauna Heater
The HUUM STEEL Electric Sauna Heater combines refined aesthetics with powerful performance, making it an ideal choice for modern home saunas. Its slim, vertical design minimizes required safety distances, allowing efficient installation even in smaller sauna rooms.
Engineered for superior airflow, the integrated air tunnel promotes faster heating while protecting internal components for long-term reliability. Despite its slender build, the STEEL accommodates a generous amount of sauna stones to deliver steady, evenly distributed warmth throughout each session.
Encased in polished stainless steel, the STEEL adds a sophisticated architectural accent to any sauna space.
For optimal comfort and safety, pair the heater with a HUUM safety railing or a custom-designed guard.
