The CLIFF Mini is the wall-mounted member of the CLIFF family - a fundamentally different installation from the floor-standing CLIFF 6, 9, and 11. Where the full-size CLIFF models stand on the sauna floor with a slender tower footprint, the CLIFF Mini mounts on the sauna wall with a bracket, taking zero floor space. At 4kW for rooms from 106 to 177 cubic feet, the CLIFF Mini is the most compact CLIFF model and the lightest electrical requirement in the CLIFF family: a 15A circuit breaker and 14 AWG wire - the lightest spec of any HUUM heater.\u003c\/p\u003e\n\u003ch4\u003eWall-mounted - the CLIFF aesthetic without the floor footprint\u003c\/h4\u003e\n\u003cp\u003eThe CLIFF Mini brings the natural stone surface exterior and the minimal safety clearances of the CLIFF family to a wall-mounted format suited for the smallest sauna rooms. Like the full CLIFF series, the CLIFF Mini is covered in natural stone panels on its exterior surfaces, giving it the visual character of a Nordic cliff face rather than a conventional electric heater. The CLIFF Mini dimensions are 10.6\"W x 6.3\"D x 38.4\"H - a tall, slim profile that mounts flush to the sauna wall on a bracket. The safety clearance from the side walls is 2\" (6 cm), making it one of the most space-efficient wall-mounted sauna heaters available. For small sauna rooms from 106 to 177 cubic feet where floor space is at a premium and the CLIFF's natural stone aesthetic is desired, the CLIFF Mini delivers both.\u003c\/p\u003e\n\u003ch4\u003e132 lbs of stone and removable ribs - more stone than comparably sized wall-mounted heaters\u003c\/h4\u003e\n\u003cp\u003eDespite its compact wall-mounted format for the smallest room range in the HUUM lineup, the CLIFF Mini carries 132 lbs (4 boxes) of rounded olivine diabase stones - substantially more than most comparably sized wall-mounted electric sauna heaters at 4kW. The higher stone capacity for its size is the result of HUUM's optimized internal basket geometry, which maximizes stone volume within the slim CLIFF form factor. The removable internal basket ribs make loading 132 lbs of 1\"-2\" (3-5 cm) rounded olivine into the narrow basket practical and precise. As with all CLIFF models, the 1\"-2\" stone size is CLIFF-specific - do not use the 2\"-4\" stones from DROP, HIVE, or STEEL packages in the CLIFF Mini basket. The integrated internal air duct speeds up heating by approximately 25% and extends element life.\u003c\/p\u003e\n\u003ch4\u003e15A \/ 14 AWG - the lightest electrical requirement of any HUUM heater\u003c\/h4\u003e\n\u003cp\u003eThe CLIFF Mini 4kW requires a 15A two-pole breaker and 14 AWG wire - lighter than every other HUUM heater including the STEEL Mini 3.5kW (20A \/ 12 AWG) and the DROP 4.5kW (30A \/ 10 AWG). For small sauna rooms in homes, apartments, or cabin saunas where the electrical panel has limited capacity, the CLIFF Mini is the most electrically accessible HUUM heater available. A licensed electrician is required. Do not connect to a GFI\/GFCI breaker. No UKU Extension Box is required for the 4kW output level.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eComplete 4kW wall-mounted sauna heater package for small rooms from 106 to 177 cubic feet.

Natural stone surface exterior - Red Dot Award-winning CLIFF design. Wall-mounted - no floor space used. 2\" safety clearance from walls. 132 lbs stone capacity - more than comparably sized wall-mounted heaters. Internal air duct - 25% faster heat-up.

The CLIFF 6kW is floor-standing for rooms from 177-318 cu ft on a 30A \/ 10 AWG circuit with 165 lbs of stones. For rooms below 177 cu ft, only the CLIFF Mini is appropriately sized in the CLIFF family. For rooms at exactly 177 cu ft, either could serve the room - the CLIFF Mini is wall-mounted with lighter electrical; the CLIFF 6 is floor-standing with more stone mass and more output. For rooms above 177 cu ft, the CLIFF 6, 9, or 11 are the floor-standing choices. The CLIFF Mini is the right choice specifically when the room is 177 cu ft or smaller, the 15A circuit is preferred or required, wall-mounted installation is wanted, and the CLIFF natural stone aesthetic is the design goal. The HUUM safety railing is strongly recommended for all CLIFF Mini installations - the heater surface reaches high temperatures and stones are at accessible height without a railing

The warranty covers defects in manufacturing and materials under normal use conditions. Heating elements are excluded from the 5-year coverage and carry their own separate warranty period. The warranty does not cover damage caused by improper installation, use of incorrect stone type or size (2\"-4\" stones must not be used - 1\"-2\" stones required), operating the heater without the required stone load, or failure to follow HUUM's installation and operating guidelines. A licensed electrician is required for all electrical connections. Do not connect to a GFI\/GFCI breaker. The HUUM safety railing is strongly recommended for all CLIFF Mini installations.
