HUUM CLIFF Mini 4kW Electric Sauna Heater – Complete Package (UKU Local Control)
This HUUM Cliff Mini 4kW Electric Sauna Heater Package (UKU Local Control) comes complete with the traditionally designed CLIFF Mini 4kW sauna heater, UKU local control, and sauna stones - everything you need to build your dream sauna experience. The package has been combined for use in sauna rooms from 106 to 177 cubic feet (CF).
The HUUM CLIFF Mini 4kW Electric Sauna Heater is a wall-mounted electric sauna heater and a slimmed-down version of the award-winning CLIFF heater. Inspired by the cliffs of the northern coast, its minimalist, stone-emphasized form adds modern elegance to any home sauna.
What sets CLIFF apart is its eco-conscious construction: the stainless steel ribs are made from cutouts left over from producing STEEL electric heaters—eliminating waste and reducing environmental impact.
Despite its compact frame, CLIFF Mini holds plenty of stones for soft, long-lasting heat for a better sauna experience. Its built-in air tunnel promotes faster heating, so you spend less time waiting.
With a safety clearance of only 60 mm (2.4 in) from the side walls and 390 mm (15.35 in) in front, the CLIFF Mini is easy to place even in smaller home saunas.
