The HUUM Drop 4.5kW brings 4.5 kW of wall-mounted electric heating to small and medium home saunas of approximately 106 to 248 cubic feet. Made in Estonia, it pairs a stainless steel body with industrial-grade heating elements, a combination chosen for corrosion resistance. The compact, minimalist profile hangs on the wall to save space in smaller rooms without compromising heat distribution.
An integrated Air Tunnel speeds up heating by 25%, lowers the amount of sauna stones needed and extends the life of the heating elements. It still takes up to 122 lbs of sauna stones for consistent, gentle steam and long-lasting heat; the stones are sold separately. The heater runs through a HUUM UKU control, sold separately and required for operation, which offers precise temperature management. The Drop 4.5kW operates on 240V single-phase power and hangs on the included bracket or sits partially embedded in a bench or floor with an optional embedding flange. Short clearances allow safer installation, and SGS certification confirms testing to US and Canadian safety standards.
