HUUM CLIFF Series 6.0kW Sauna Heater

HUUM CLIFF 6.0kW Sauna Heater

The HUUM CLIFF 6.0kW sauna heater is a slim, floor-mounted electric heater engineered for modern sauna spaces where efficiency, safety clearances, and clean design are essential. Featuring remarkably short safety distances and a vertical, space-saving profile, the CLIFF 6.0kW is ideal for saunas with limited floor space that still demand powerful, even heat.

An internal air duct allows the heater to warm up to 25% faster, while the exposed stone design produces a longer-lasting, milder heat that feels smooth and balanced. Built from stainless steel and engineered for performance, the CLIFF 6.0kW delivers premium sauna comfort in both residential and light commercial environments.

Please Note: A UKU control system and sauna stones are required for operation and are sold separately.
