The DROP 9kW is the highest output model in the DROP series - the top of the range for sauna rooms that exceed what the 4.5kW, 6kW, and 7.5kW models can cover. It shares the same external body dimensions, the same 122-lb stone capacity, and the same water-droplet design as every other DROP model. What changes at 9kW is the electrical requirement: a 50A breaker and 6 AWG wire, and the room coverage that steps up to 460 cubic feet.\u003c\/p\u003e\n\u003ch4\u003e9kW - the top of the DROP series for the largest rooms\u003c\/h4\u003e\n\u003cp\u003eThe DROP series runs from 4.5kW to 9kW across four models with identical external dimensions. At 9kW, the DROP covers sauna rooms from 318 to 460 cubic feet - the range appropriate for large residential saunas, multi-bench installations, and sauna rooms with significant cold surfaces (glass walls, tile floors, natural stone or masonry panels) that increase the adjusted room load beyond what a smaller model can effectively heat. The 9kW model has more heating elements inside the same cage as the 4.5, 6, and 7.5kW versions - the physical size of the basket and the 122-lb stone capacity are identical across all four output levels. For rooms at or approaching 460 cubic feet, the DROP 9 is the appropriate choice within the DROP series. For rooms exceeding 460 adjusted cubic feet, HUUM's STEEL or other higher-output models should be considered.\u003c\/p\u003e\n\u003ch4\u003e50A \/ 6 AWG - planning the electrical installation\u003c\/h4\u003e\n\u003cp\u003eThe DROP 9kW requires a dedicated 240V\/1-phase circuit with a 50A two-pole breaker and 6 AWG wire. This is a heavier electrical specification than the DROP 4.5 and 6 (both 30A \/ 10 AWG) and the DROP 7.5 (40A \/ 8 AWG). For new sauna installations where the electrical panel is being planned from scratch, specifying a 50A circuit for the DROP 9 is straightforward. For retrofits where the panel has limited capacity, it is worth confirming available breaker slots and panel headroom before ordering. All electrical work must be completed by a licensed electrician in compliance with local codes. Do not connect to a GFI\/GFCI breaker.\u003c\/p\u003e\n\u003ch4\u003e122 lbs of stone and UKU control - same specification as every DROP\u003c\/h4\u003e\n\u003cp\u003eThe DROP 9 carries the same 122-lb stone capacity as every DROP model and the same rounded olivine diabase stone specification: 2\"-4\" (5-10 cm) rounded stones for dense packing, good water flow when ladling, and soft, consistent steam throughout the session. The 4 boxes of stones included in this package are the correct type and quantity for the DROP 9. The UKU control is included - choose UKU Local Black for on-site digital control, or upgrade to UKU WiFi at checkout for HUUM app remote preheat and scheduling on iOS and Android. Neither variant requires an extension box for the DROP 9kW.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eComplete 9kW wall-mounted sauna heater package for rooms from 318 to 460 cubic feet.
