HUUM Cliff Mini 3.5 package: a slender wall heater with control and stones for saunas from 123 to 212 cubic feet
The HUUM Cliff Mini 3.5 package pairs the wall mounted Cliff Mini electric sauna heater with its control and stones for very small rooms from 123 to 212 cubic feet. The 3.5 kW heater is a narrow stainless steel column made in Estonia. It measures about 10.6 inches wide, 6.3 inches deep, and 38 inches tall and weighs 33 pounds. Removable front ribs make it easier to stack the stones neatly. An internal air duct helps it heat up to 25 percent faster, and it holds 133 pounds of stones in direct contact with the heating elements.
The package includes the heater, a HUUM UKU control with its sensors and cables, and 132 pounds of rounded olivine sauna stones. The UKU lets you set the temperature from 104 to 230 degrees and schedule the sauna to start up to 48 hours ahead. On the page you choose the control: the standard UKU, or the Wi-Fi, Mirror, or Gold version that lets you start the sauna from your phone. A bucket and ladle set is optional. Have a little more room? See the floor standing HUUM Cliff 6 heater package. The HUUM Cliff Mini 3.5 package ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
