Everything needed to operate the heater arrives together. The DROP 6kW is the mid-range model in the DROP series, stepping up from the 4.5kW for the 177-318 cu ft room range while sharing the same external body dimensions, the same 122-lb stone capacity, and the same water-droplet design language. The 6kW requires the same 30A breaker and 10 AWG wire as the DROP 4.5, making it the largest DROP output level that fits a standard 30A residential circuit.\u003c\/p\u003e\n\u003ch4\u003eDROP 6kW - the largest DROP on a 30A circuit\u003c\/h4\u003e\n\u003cp\u003eThe DROP series is available in four output levels - 4.5kW, 6kW, 7.5kW, and 9kW. The 4.5kW and 6kW both run on 30A \/ 10 AWG circuits. The 7.5kW steps up to 40A \/ 8 AWG, and the 9kW requires 50A \/ 6 AWG. For buyers whose sauna room falls in the 177-318 cu ft range, the DROP 6kW is the correct and most electrically efficient choice - it handles rooms up to 80 cubic feet larger than the DROP 4.5 without requiring any additional electrical capacity beyond a standard 30A double-pole breaker. All four DROP models share identical external body dimensions at 15.4\"W x 13.2\"D x 23.3\"H - the physical size of the cage does not change between output levels, only the number of heating elements inside it.\u003c\/p\u003e\n\u003ch4\u003e122 lbs of stone - the DROP's defining specification\u003c\/h4\u003e\n\u003cp\u003eThe DROP 6kW carries the same 122 lbs (55 kg) of rounded olivine diabase stones as every model in the DROP series. This stone load is the characteristic that defines the DROP experience across all four output levels: more stone mass than most wood-burning stoves, direct element-to-stone contact for even heat distribution, and soft, long-lasting loyly when water is ladled over the stones. HUUM specifies rounded olivine diabase in 2\"-4\" (5-10 cm) size for the DROP specifically - the rounded form allows denser packing, better water flow between stones, and milder steam character than angular crushed stones. The 4 boxes of stones included in this package are the correct specification for the DROP 6.\u003c\/p\u003e\n\u003ch4\u003eUKU control - Local or WiFi, selected at checkout\u003c\/h4\u003e\n\u003cp\u003eThe package includes the UKU Local Black control as standard, with UKU WiFi available as an upgrade at checkout. The UKU Local Black is a digital sauna control that manages the heater on\/off, temperature, timer, and safety functions from panel-mounted buttons. The UKU WiFi variant adds HUUM app connectivity for iOS and Android - remote preheat from anywhere, session scheduling, and live temperature monitoring. Both UKU variants are fully compatible with the DROP 6kW without any extension box. The UKU Extension Box is only required for HUUM heaters over 11kW and is not needed for any model in the DROP series. The control mounts outside the sauna room or at the correct safety distance if inside.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eComplete 6kW wall-mounted sauna heater package for rooms from 177 to 318 cubic feet.

For well-insulated wood-walled rooms in the 177-248 cu ft overlap, either model is appropriate; the DROP 6 provides headroom. For rooms from 249 to 318 cu ft, the DROP 6 is the correct model.
