HUUM CLIFF 6STU Package

The HUUM CLIFF 6STU Package combines the 6.0 kW HUUM CLIFF 6 electric sauna heater, HUUM UKU control system, and 165 lb of rounded sauna stones into a coordinated package for sauna rooms from 177 to 318 cubic feet. The CLIFF 6 features an exceptionally slim 10.6 × 10.6 in footprint, making it well suited for sauna layouts where floor space is limited. Its open stainless steel construction surrounds the heating elements with a substantial stone mass, while an integrated internal air duct is designed to improve airflow through the heater. HUUM states that this design can reduce heat-up time by up to 25%. The included UKU system provides digital control of power, time, temperature, and delayed start. The standard package includes a black control panel, while Wi-Fi connectivity and alternative control-panel options are available as upgrades. Package includes the 6.0 kW CLIFF 6 heater, UKU control system, and 165 lb of 1–2 in (3–5 cm) rounded sauna stones.
