Description
A slim electric sauna heater for larger saunas
The CLIFF 10.5 kW packs serious power into a narrow stainless-steel body. With remarkably small safety distances it fits rooms where a bulkier heater won’t, and it’s sized for saunas from 354 to 566 cu ft.
Deep, even, lasting heat
A 165 lb stone capacity — with removable ribs for accurate stacking and direct stone-to-element contact — delivers a longer, milder heat and generous löyly across a larger room.
Wi-Fi control with HUUM UKU
Run it with a HUUM UKU or UKU Wi-Fi control to preheat from your phone. Stainless steel construction, designed, engineered and made in Estonia.
Required UKU control and sauna stones (5 boxes) sold separately.
