Description
Fit serious heat into a tighter space with the Huum Cliff 9kW electric sauna heater, made for sauna rooms of 317 to 529 cubic feet. The slim CLIFF has remarkably small safety distances, which makes it a good fit for saunas with limited space. Its internal air duct heats the room up to 25% faster.
It is sold as the heater only, which makes it a simple swap if you already have a HUUM UKU control and stones. It runs from a HUUM UKU control (UKU Local, UKU 4.2 Wi-Fi or UKU Glass, sold separately), and you can add a control and the five boxes of extra small sauna stones it needs (33 lbs each) on this page. Designed and engineered in Estonia.
