HUUM CLIFF is a slim, vertical electric sauna heater available in wall-mount Mini and floor-standing versions. When sized correctly, CLIFF can reach temperatures up to 230°F. Its tall stone column packs significant mass for such a compact footprint, which produces soft, even löyly that home users value in tight layouts or next to glass.

HUUM CLIFF Overview

CLIFF delivers HUUM’s signature modern look in a space-saving tower. The narrow footprint and upright basket let you position the heater closer to wood surfaces while still enjoying the soft steam and even heat that a large stone mass provides. Choose CLIFF Mini 4 for small rooms that need wall mounting or step up to CLIFF 6, 9, and 11 for medium rooms that benefit from a floor-standing tower.  

Control System

All HUUM sauna heaters use the same control system. This control system is called UKU. In all HUUM sauna heaters, there will be an external control panel for controlling the sauna.
HUUM allows the UKU to be installed inside the sauna room, as long as their specific instructions regarding the placement are followed. However, it's more common to install your control panel right outside the sauna, where it doesn't get exposed to heat and humidity.
HUUM offers an additional feature to all UKU controls that allows you to control the sauna remotely through an app on your phone.

Technical Details

HUUM CLIFF comes in four configurations across two formats: wall-mounted CLIFF Mini 4 and floor-standing CLIFF 6, 9, and 11. The slender tower profile stays consistent while higher kW models add element power inside the basket. The bigger your sauna, the greater the kilowatt rating you will need.  


Here are the electrical specs when you wire your CLIFF sauna heater with 240 V:

  • CLIFF 6 kW for sauna rooms sized 176.5–353 ft³. This model draws 25 A, requires a 30 A circuit breaker, and uses 10 AWG wire.  
  • CLIFF 9 kW for sauna rooms sized 318–530 ft³. This model draws 37.5 A, requires a 50 A circuit breaker, and uses 8 AWG wire.  
  • CLIFF 11 kW for sauna rooms sized 353–600 ft³. This model draws 43.75 A, requires a 50 A circuit breaker, and uses 6 AWG wire.

Sizing Guidance

  1. Calculate your room volume in cubic feet.
  2. Adjust for cold surfaces such as glass, tile, and stone to maintain warm-up speed and steam quality.
  3. Consider insulation for outdoor cabins.
  4. If you are between models, choose the larger firebox for faster heat-up and better recovery between water ladling.

Conclusion

HUUM CLIFF is the right choice if you want soft, even löyly from a compact tower with the flexibility to heat hotter when you want a more intense session. The vertical stone column gives you stable temperatures and generous steam without taking over your floor plan. Pick CLIFF Mini 4 for small rooms that benefit from a wall mount or move to CLIFF 6, 9, or 11 for medium rooms that need a floor-standing unit. Pair with UKU Wi-Fi for scheduling, remote starts, and added safety features.
