Required for operation (sold separately): HUUM UKU control; 165 lbs of sauna stones (5 × 33 lb boxes, 1″–2″ (3–5 cm) stones).
The HUUM CLIFF is a slender electric sauna heater with remarkably small safety distances, which makes it a strong fit for saunas with limited space. An internal air duct helps it heat up to 25% faster, according to HUUM.
Choose 6, 9, or 10.5 kW to match your room size (see the model table below). Every CLIFF runs on 240V single-phase power, is hardwired, and is built from brushed stainless steel. It works with the HUUM UKU control.
