The HUUM CLIFF is the classic column heater done properly — a stainless steel cylinder that stands on the sauna floor and carries its stones in the open, so they sit in direct contact with the elements. The result is the softer, longer heat traditional bathers look for, and enough thermal mass to keep giving steam long after the löyly water hits.
Four sizes, one page. Pick the output that matches your room — the CLIFF Mini 4 at 3.5 kW suits rooms from 123 cubic feet, the 10.5 kW handles rooms to 600 — then choose whether you want the heater on its own or a complete package with a HUUM UKU control and sauna stones. Pricing updates as you choose.
About the UKU control. UKU Local gives you settable on/off, time, temperature and delayed start up to 48 hours ahead. The Wi-Fi versions add the HUUM mobile app so you can preheat from anywhere, in black, glass or mirror finishes.
Complete this installation
HUUM makes these to fit one heater body. These are the ones for the size you have selected.
The fitment parts for this size are not listed yet — get in touch and we will quote them.
A safety rail is not required for the heater to work, but it is what keeps skin off a casing that runs above 200°F. We would not install one of these without it.
