The HUUM CORE 10.5kW Black is a floor-mounted electric sauna heater rated at 10.5 kW on 240V or 7.9 kW on 208V, covering sauna rooms of 354 to 566 cubic feet (240V) or 265 to 424 cubic feet (208V). Engineered in Estonia for residential and light commercial use, it is finished in CORE Black matte metal with a black top rim cover. Its compact form suits custom bench layouts, including full-length bench embedding.
Water ladled over the sauna stones (sold separately) produces smooth, abundant steam and balanced humidity. A HUUM UKU Local, Wi-Fi or Glass control system (sold separately) is required, and the Wi-Fi models add mobile app control. The heater comes in dedicated 240V and 208V single-phase versions that are not dual-voltage or field-convertible. It needs only 2" of side clearance, ships with four adjustable leveling legs and floor anchoring brackets, and must be hardwired by a licensed electrician. IPX4 splash resistance, an SGS listing and a 3-year limited residential warranty (1-year commercial, heating elements excluded) complete the package.
