This listing is the heater only. A UKU control unit and sauna stones are required for operation and sold separately. The DROP 4.5 is the entry model in the HUUM DROP wall-mounted series - the smallest output in the DROP range for rooms from 106 to 177 cubic feet on a single 30A \/ 10 AWG circuit. No UKU Extension Box is required. The DROP 4.5 delivers the distinctive DROP water-droplet profile and 122-lb stone capacity of the full DROP series in the output appropriate for personal home saunas, apartment saunas, and compact two-person rooms. For a complete installation including control and stones in a single purchase, see the HUUM DROP 4.5STU Package listing at BathingBrands.\u003c\/p\u003e\n\u003ch4\u003eThe DROP design - water-droplet form, wall-mounted, 122 lbs of stone\u003c\/h4\u003e\n\u003cp\u003eThe HUUM DROP is one of the most recognised sauna heater silhouettes in contemporary sauna design - a smooth, rounded water-droplet form that mounts on the sauna wall with the pointed end facing downward. Unlike conventional rectangular wall-mounted heaters, the DROP's curved profile reads as a sculptural object in the sauna room rather than an appliance. At 4.5kW for rooms from 106 to 177 cubic feet, the DROP 4.5 carries 122 lbs of 2\"-4\" (5-10 cm) rounded olivine diabase stones - a generous stone capacity for a small-room wall-mounted heater, providing good thermal mass for sustained steam quality in the compact room it serves. The stone placement video in the documents section below covers the correct method for loading 122 lbs of stones into the DROP basket, which is important for element life and steam performance.\u003c\/p\u003e\n\u003ch4\u003e4.5kW - the entry DROP for rooms 106-177 cu ft\u003c\/h4\u003e\n\u003cp\u003eThe DROP series runs from 4.5kW to 9kW: DROP 4.5 (106-177 cu ft, 30A \/ 10 AWG), DROP 6 (177-318 cu ft, 30A \/ 10 AWG), DROP 7.5 (248-389 cu ft, 40A \/ 8 AWG), and DROP 9 (318-530 cu ft, 50A \/ 8 AWG). The DROP 4.5 is the correctly sized DROP for rooms at the small end of the HUUM range - personal home saunas, pre-built sauna cabins for one or two people, apartment saunas, and smaller-footprint dedicated sauna rooms. For rooms below 106 cu ft or above 177 cu ft, a different DROP or a different HUUM heater series is appropriate. The Size Your Sauna document below and the HUUM heater calculator at BathingBrands confirm the correct model for a specific room size.\u003c\/p\u003e\n\u003ch4\u003eStone placement matters - follow the Stone Placement Video\u003c\/h4\u003e\n\u003cp\u003eCorrect stone placement in the DROP basket is important for heating element longevity and steam quality. The DROP's curved basket geometry requires stones to be loaded in a specific pattern that ensures adequate airflow around the elements and even thermal contact across the stone mass. The Stone Placement Video in the documents section below walks through the correct loading procedure step by step. Incorrect stone placement - packing stones too tightly around the elements or loading stones of the wrong size - is one of the most common causes of early element failure in DROP heaters. Use only 2\"-4\" (5-10 cm) rounded olivine stones as specified in the Stone Requirements document.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"sl-hook\"\u003e4.5kW wall-mounted sauna heater for rooms from 106 to 177 cubic feet.
