Description

A slim electric sauna heater for tight spaces

The CLIFF 9 kW is engineered around one problem: fitting a serious heater into a compact sauna. Its narrow stainless-steel body carries remarkably small safety distances, so it slots into rooms where a bulkier heater won’t. Designed for saunas from 283 to 460 cu ft.

Faster heat, deeper steam

An internal air duct pulls the CLIFF up to 25% faster than comparable heaters. A 165 lb stone capacity — with removable ribs for accurate stacking and direct stone-to-element contact — gives you a longer, milder heat and generous löyly.

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 and industrial-quality elements, designed, engineered and made in Estonia.

Required UKU control and sauna stones (5 boxes) sold separately.
