The HIVE Mini 9 steps up from the HIVE Mini 6 with 50% more output for the same physical body and the same 330-lb stone capacity, extending the room range into the 318-530 cu ft territory that the 6kW cannot serve. The key electrical difference from the HIVE Mini 6: the 9kW requires a single 50A breaker and 8 AWG wire rather than the 6kW's 30A \/ 10 AWG - a heavier but still single-circuit specification with no UKU Extension Box required.\u003c\/p\u003e\n\u003ch4\u003eHIVE Mini 9 vs HIVE Mini 6 - more output, heavier circuit, same body\u003c\/h4\u003e\n\u003cp\u003eAll three HIVE Mini models - 6kW, 9kW, and 10.5kW - share identical external body dimensions: 18.11\" (460mm) diameter, 29.5\" (750mm) height. The physical footprint in the sauna room, the 330-lb stone capacity, the pre-installed air tunnel, and the floor-standing installation method are the same across all three. What changes is the output level and the electrical requirement. The HIVE Mini 6 runs on a single 30A \/ 10 AWG circuit. The HIVE Mini 9 and 10.5 both require a single 50A \/ 8 AWG circuit. For rooms from 318 to 530 cubic feet where the HIVE Mini 6's 318 cu ft ceiling is insufficient, the HIVE Mini 9 is the correct step up - provided the electrical panel can supply a single 50A double-pole breaker slot and the electrician can run 8 AWG wire to the UKU control location.\u003c\/p\u003e\n\u003ch4\u003e318-530 cu ft - mid-size residential saunas and sauna cabins\u003c\/h4\u003e\n\u003cp\u003eThe 9kW range of 318-530 cubic feet covers mid-size dedicated home sauna rooms, two-bench sauna cabins, and smaller commercial installations. At this range, the sauna room is typically a purpose-built space rather than a converted interior room. Rooms approaching 530 cubic feet with cold surfaces - glass walls, tile floors, or natural stone panels - require calculating the adjusted cubic footage to confirm whether the HIVE Mini 9 or the HIVE Mini 10.5kW is the correct model. Use the HUUM heater calculator in the Size Your Sauna document below to verify before selecting. The HIVE Mini 9 and HIVE Mini 10.5 share the same 50A \/ 8 AWG electrical requirement, so the output choice between them does not affect the electrical installation.\u003c\/p\u003e\n\u003ch4\u003e330 lbs of stone, air tunnel pre-installed - same as HIVE Mini 6\u003c\/h4\u003e\n\u003cp\u003eThe HIVE Mini 9 carries the same 330-lb stone capacity as the HIVE Mini 6 in the same 18.11\" diameter open beehive cage. The air tunnel is pre-installed on the heater as standard. It directs airflow more efficiently through the stone mass during warm-up, speeding up heating by approximately 25% and extending heating element life. The 10 boxes of rounded olivine diabase stones (2\"-4\", 5-10 cm) included in this package are the correct type and quantity for the HIVE Mini 9. This package ships on a wooden pallet by freight and requires a scheduled delivery appointment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eComplete 9kW floor-standing sauna heater package for rooms from 318 to 530 cubic feet.

The 9 and 10.5 ranges overlap from 353 to 530 cu ft: in this overlap zone, a well-insulated standard room at the lower end may be adequately served by the 9kW; a room with cold surfaces or high-frequency use benefits from the 10.5kW's headroom.
