The DROP 7.5 steps up from the DROP 6 into the room range that requires a 40A circuit - it is the only DROP model on a 40A \/ 8 AWG specification, sitting between the 30A DROP 6 and the 50A DROP 9. For rooms from 248 to 389 cubic feet where the DROP 6's 318 cu ft ceiling is insufficient but the DROP 9's 50A circuit is more electrical capacity than needed, the DROP 7.5 is the precisely matched choice: more output than the 6kW, lighter electrical requirement than the 9kW. All four DROP models share identical body dimensions, the same 122-lb stone capacity, and the same Red Dot Award-winning water-droplet form.\u003c\/p\u003e\n\u003ch4\u003eDROP 7.5 - the mid-step between the 30A and 50A DROP models\u003c\/h4\u003e\n\u003cp\u003eThe DROP series runs from 4.5kW to 9kW across four output levels. The 4.5kW and 6kW both operate on 30A \/ 10 AWG circuits. The 9kW requires a 50A \/ 6 AWG circuit. The 7.5kW occupies the middle position: a 40A \/ 8 AWG circuit - heavier than the 30A models but lighter than the 50A 9kW. For buyers whose electrical panel can supply a 40A double-pole breaker but who prefer to avoid the heavier 50A \/ 6 AWG wire run of the 9kW, the DROP 7.5 provides 7.5kW of output on an intermediate circuit specification. For rooms in the 248-389 cu ft range, it is also the most precisely matched choice: not undersized (as the DROP 6 would be for rooms above 318 cu ft) and not oversized (as the DROP 9 would be for rooms below 318 cu ft).\u003c\/p\u003e\n\u003ch4\u003eSame 122-lb stone capacity and body as every other DROP\u003c\/h4\u003e\n\u003cp\u003eLike all DROP models, the 7.5kW carries 122 lbs (55 kg) of rounded olivine diabase stones in the same 15.4\"W x 13.2\"D x 23.3\"H water-droplet body. The physical heater is identical in size and form to the DROP 4.5, 6, and 9 - only the number of heating elements inside the cage changes between output levels. The 4 boxes of 2\"-4\" rounded olivine diabase stones included in this package are the correct type and quantity for the DROP 7.5. HUUM specifies rounded olivine diabase in the 2\"-4\" size specifically for the DROP basket geometry - for dense stone packing, good water flow when ladling, and soft, consistent steam throughout the session.\u003c\/p\u003e\n\u003ch4\u003eUKU control - Local Black 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 provides on-site digital control of temperature, timer, and safety functions from the panel. The UKU WiFi variant adds HUUM app connectivity for iOS and Android - remote preheat, session scheduling, and live temperature monitoring. Neither variant requires a UKU Extension Box for the DROP 7.5kW. The extension box is only required for HUUM heaters over 11kW and is not needed for any model in the DROP series.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003eComplete 7.5kW wall-mounted sauna heater package for rooms from 248 to 389 cubic feet.

The mid-step DROP - 40A \/ 8 AWG, between the 30A DROP 6 and the 50A DROP 9. Same 122 lb stone capacity and Red Dot Award-winning body as all DROP models.
