This listing is the heater only. A compatible UKU control unit and sauna stones are sold separately. The CORE is HUUM's distinctive wood-clad heater series - a stainless steel open stone basket surrounded by natural wood panels that give the heater the warmth and texture of a timber sauna element rather than a metal appliance. The Alder variant uses alder wood for its exterior cladding - a lighter, fine-grained Nordic hardwood with a warm pale tone that integrates naturally with light-wood sauna interiors. The CORE Alder Package listing at BathingBrands bundles the heater with a UKU control and stones for a complete single purchase.\u003c\/p\u003e\n\u003ch4\u003eThe CORE design - stainless basket, natural wood exterior\u003c\/h4\u003e\n\u003cp\u003eThe HUUM CORE heater combines an open stainless steel stone basket with natural wood panels on the exterior sides. The stones are visible through the open basket structure and the wood cladding wraps the sides of the heater, presenting a warm natural wood face to the sauna room rather than the bare metal of a conventional electric heater. The result is a heater that reads as a wood-and-stone element - visually consistent with the natural timber and stone materials of a traditional sauna interior - while delivering the precision control and efficiency of a modern electric heater with UKU app connectivity. The open basket allows direct stone-to-element contact throughout the full stone load for even heat distribution, and water ladled onto the stones produces soft, consistent steam from stones at multiple temperature levels throughout the basket depth.\u003c\/p\u003e\n\u003ch4\u003eAlder wood cladding - the lightest CORE exterior\u003c\/h4\u003e\n\u003cp\u003eThe CORE series offers multiple wood species for the exterior cladding: Black (painted black finish), alder, thermo-aspen, and aspen. Alder is the lightest and most neutral-toned of the natural wood options - a pale, fine-grained wood with a warm creamy tone that suits sauna rooms with light Nordic timber, white or light grey tile, and pale stone interiors. Where thermo-aspen has the deep brown warmth of thermally modified wood and aspen has the lighter natural softwood tone, alder occupies the mid-warm neutral position - a natural wood look without the golden-yellow tones of some other species. For sauna rooms designed around a light, airy Nordic aesthetic where the heater should feel like a natural wood element without adding warmth to the colour palette, the CORE Alder is the appropriate finish choice in the CORE family.\u003c\/p\u003e\n\u003ch4\u003eUp to 10.5kW - output selected at purchase\u003c\/h4\u003e\n\u003cp\u003eThe CORE series is available in multiple output configurations up to 10.5kW. The specific output selected determines the room coverage and electrical specification. UKU control (Local Black or WiFi) and sauna stones are required for operation and sold separately at BathingBrands. The UKU Local Black provides on-site digital control of temperature, time, and safety functions. UKU WiFi adds HUUM app remote preheat, scheduling, and monitoring on iOS and Android. A compatible UKU Extension Box may be required depending on the output level selected - confirm with the control unit specifications. A licensed electrician is required for all electrical connections.
