HUUM CLIFF 9 9kW 240V Electric Sauna Heater – Complete Package (UKU WiFi Control)
This HUUM CLIFF 9kW Electric Sauna Heater Package (UKU WiFi Control) comes complete with the traditionally designed CLIFF 9kW sauna heater, UKU wi-fi control, and sauna stones - everything you need to build your dream sauna experience. The package has been combined for use in sauna rooms from 283 to 460cubic feet.
The HUUM CLIFF 9kW Electric Sauna Heater combines bold Nordic-inspired design with precision engineering for modern sauna spaces. Featuring a natural stone exterior that mirrors the rugged beauty of northern cliffs, the CLIFF stands out for both its aesthetics and efficient, sustainable build.
Crafted from stainless steel cutouts repurposed during the production of HUUM’s STEEL series, this heater minimizes material waste while maintaining exceptional durability. Its slim, space-saving profile and small safety distances make it an excellent choice for compact sauna rooms, while the internal air tunnel design helps improve heat-up time and element longevity.
With its generous stone capacity, the CLIFF delivers even, consistent warmth and balanced heat distribution throughout each session. Recognized globally for design excellence, the CLIFF received the Red Dot Design Award in 2021.
For enhanced safety and comfort, pair the heater with a HUUM safety railing or a custom-built guard.
