CLIFF Mini electric sauna heater is a slimmer, wall-mounted version of the award-winning CLIFF heater. Inspired by northern coastal cliffs, this heater catches the eye with its stone-emphasized design. What makes both CLIFF heaters unique is their innovative and eco-friendly construction. The ribs of CLIFF heaters are created from cutouts generated during the production of STEEL electric heaters. This eliminates material waste and allows two heaters to be made from the same stainless steel sheet. Despite its slender form, CLIFF Mini can hold plenty of heating stones, providing a mild and long-lasting steam experience. The built-in air tunnel ensures fast heating. With a safety distance of only 6 cm from the walls, CLIFF Mini is easy to place even in smaller home saunas.
Sauna heaters for small steam rooms
CLIFF electric sauna heater has been developed with a focus on apartment saunas. It’s a classy alternative for electric sauna heaters that hold a small amount of sauna stones and often provide sharp and abrupt steam. The compactness of this sauna heater doesn’t mean any compromises on appearance.
Well-planned construction ensures the efficiency and small safety distances of the slim CLIFF sauna heater. Internal air tunnel ensures effective air flow and expedites sauna heating by 25%. In addition, it prolongs the useful life of the heating elements. You’ll need 50 kg of sauna stones for mild steam. CLIFF electric sauna heater holds as much as 75 kg of stones, and the wall-mountable CLIFF Mini fits 60 kg of sauna stones.
The compact HUUM CLIFF Mini 3.5 kW sauna heater, with extremely short safety distances, is a wall-mounted electric sauna heater that is especially engineered for smaller sauna rooms up to 212 cubic feet (CF).
Because of its intelligent design, the CLIFF Mini has a much higher rock volume than other sauna heaters its size. A larger rock capacity results in a consistent, soft, high heat for a better sauna experience, greater efficiency, and more steam.
The CLIFF's contemporary design will add an elegant, upscale look to your home sauna.
