    Why choose CORE

    CORE is HUUM’s design-flexible electric heater. The heating chassis disappears behind a finished exterior, allowing the heater to read more like sauna furniture than exposed equipment.

    • This listing is configured for Alder exterior panels with a customer-selectable black or stainless-steel inlay.
    • The current manual specifies 88.2 lb of stones; this supersedes the older 66-lb distributor field.
    • All models share a compact 15.16-inch square finished footprint and 2-inch side clearance.
    • Current direct UKU capacity covers all three models; no extension box is required.

    Choose the correct model

    Current U.S. model Room Output Amps Breaker Wire Stones
    CORE Alder 6 177-318 ft³ 6.5 kW 25 A 30 A 10 AWG 88 lb
    CORE Alder 9 283-460 ft³ 9 kW 37.5 A 50 A 8 AWG 88 lb
    CORE Alder 11 354-566 ft³ 10.5 kW 43.75 A 50 A 8 AWG 88 lb

    Stone requirement: 88.2 lb in the current U.S. manual; use clean, durable sauna stones. Dimensions: Finished CORE footprint: 15.16 in square x 32.7 in H.

    Required to complete the system

    • HUUM UKU Local or Wi-Fi control
    • Approximately 88 lb of clean 2 to 4-inch sauna stones
    • Licensed-electrician installation
    • Alder exterior package with the selected black or stainless-steel inlay

    Controller, stones, accessories, and installation labor are not included unless a bundle explicitly says otherwise.

    Planning notes that matter

    • Add 3.3 ft³ for each square foot of uninsulated glass, tile, or brick.
    • The manual’s 43.3-inch measurement is from heater top to ceiling, not total room height.
    • Contact Sauna Marketplace before ordering if you need Aspen, Thermo-Aspen, or another custom-finished CORE configuration.

    Current warranty

    HUUM’s current limited warranty is 3 years for private use and 1 year for commercial use. Heating elements, accessories, sauna stones, and controller sensors are excluded. Read the current terms in Manuals & Documents.
