Know before you buy
No, the heater requires an external control unit, which must be purchased separately. This allows you to choose the specific HUUM controller that best fits your needs, such as a wall-mounted panel or a mobile-app-compatible unit.
The 9 kW model is typically suited for sauna rooms ranging from approximately 315 to 530 cubic feet. Be sure to account for non-insulated surfaces like glass or stone, which may require a higher power output.
The stainless steel design is highly durable and requires minimal maintenance. We recommend occasionally wiping down the exterior with a damp cloth and ensuring the sauna stones are inspected and rearranged annually to maintain optimal airflow.
While you can use standard sauna stones, we recommend using HUUM-certified olivine diabase stones. These are specifically sized to fit the heater's design, ensuring proper heat distribution and longevity of the heating elements.
Yes, the Cliff 9 kW is designed for residential use. Its compact, wall-mounted footprint makes it an excellent choice for modern home saunas where space efficiency and high-performance heating are priorities.
