{"product_id":"finnleo-himalaya-sauna-heater","title":"Finnleo Himalaya SL2 Sauna Heater","description":"\u003ch2\u003eFinnleo Himalaya SL2 Sauna Heater\u003c\/h2\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eFinnleo Himalaya electric sauna heater\u003c\/strong\u003e is Finnleo's best-selling floor-standing rock-tower heater and the centerpiece of the modern Finnish sauna experience. A tall column of stone surrounds the heating elements on every side, putting an exceptional mass of rock in direct contact with the heat for deep, enveloping warmth and an abundant, soft löyly (steam). The Himalaya is available in three configurations to match nearly any home, spa, or commercial sauna room: \u003cstrong\u003e7.0 kW (240V, 1-Phase)\u003c\/strong\u003e, \u003cstrong\u003e9.0 kW (240V, 1-Phase)\u003c\/strong\u003e, and \u003cstrong\u003e9.0 kW (208V, 3-Phase)\u003c\/strong\u003e — all sharing the same award-winning rock-tower design, BioWater Technique humidity system, and SaunaLogic2 smart control compatibility.\u003c\/p\u003e\n\n\u003ch2\u003eRock Tower Construction\u003c\/h2\u003e\n\u003cp\u003eEvery Himalaya heater is built around a vertical rock tower that holds approximately \u003cstrong\u003e210 lb of sauna rocks\u003c\/strong\u003e, supplied standard with the unit. The elements are fully surrounded by stone on all sides rather than exposed on top, so heat radiates gently and evenly through the rock mass instead of blasting directly off open elements. This produces the soft, deep heat and gentle löyly Finnleo is known for, while the tower's slim vertical footprint fits neatly into corner installations, mid-sauna placements, or through-bench configurations.\u003c\/p\u003e\n\n\u003ch2\u003eStandard BioWater Technique (BWT)\u003c\/h2\u003e\n\u003cp\u003eEvery Himalaya model includes Finnleo's integral \u003cstrong\u003eBioWater Technique (BWT)\u003c\/strong\u003e water tank as a standard feature, not an add-on. The BWT tank hangs directly on top of the heating elements beneath the rocks and produces a continuous, soft boil of water throughout the sauna session, gently raising ambient humidity so bathers can enjoy a hotter-feeling sauna at a lower, more comfortable air temperature. To use it, allow the heater to warm up for about 20 minutes, then add roughly 2 cups of fresh water through the side slots of the fragrance diffuser (never use pool or spa water, as chlorine will corrode the heater). A separate, non-slotted diffuser port is provided for adding fragrance oils — oils should never be poured directly into the water reservoir, as they can foam and leave a lingering scent in the tank. Additional water can be poured directly onto the rocks at any time for a quick spike of humidity. The BWT tank and sleeve should remain installed with the rocks at all times; adding water is optional for bathers who prefer a drier, lower-humidity sauna.\u003c\/p\u003e\n\n\u003ch2\u003eModel Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHimalaya 7.0 kW (240V, 1-Phase):\u003c\/strong\u003e sized for sauna rooms of approximately 175–350 cubic feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHimalaya 9.0 kW (240V, 1-Phase):\u003c\/strong\u003e sized for larger sauna rooms of approximately 310–500 cubic feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHimalaya 9.0 kW (208V, 3-Phase):\u003c\/strong\u003e same 310–500 cubic foot capacity as the 9.0 kW single-phase model, engineered for commercial or 3-phase electrical service installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAll three models ship with approximately 210 lb of rocks included and require a matching SaunaLogic2 control and contactor (CB) box, sized to the heater's voltage and phase, for proper operation.\u003c\/p\u003e\n\n\u003ch2\u003eSaunaLogic2 (SL2) Smart Control\u003c\/h2\u003e\n\u003cp\u003eEvery Himalaya heater is designed to run on Finnleo's SaunaLogic2 control system, available in Wi-Fi and non-Wi-Fi versions.

Bathers can cycle through a full color sequence — white, red, green, blue, yellow, aqua, purple, and full rotation — and adjust brightness in 25%, 50%, 75%, or 100% increments directly from the SL2 control glass. Lights automatically shut off 10 minutes after a session ends as a safety feature, and fixtures must be positioned away from direct bather contact due to heat generated during use.\u003c\/p\u003e\n\n\u003ch2\u003eWood \u0026amp; Interior Finish\u003c\/h2\u003e\n\u003cp\u003eThe Himalaya heater is designed to be installed within a sauna room finished in traditional tongue-and-groove softwood paneling, with wall construction consisting of 2x4 framing, fiberglass insulation (minimum R-12), a foil vapor barrier, and 1\/2\" wallboard. Finnleo advises against using any wood stain, sealer, or preservative on interior sauna surfaces, preserving the natural softwood's ability to absorb and release moisture for an authentic Finnish sauna feel.\u003c\/p\u003e\n\n\u003ch2\u003eHeater Guard \u0026amp; Safety Clearances\u003c\/h2\u003e\n\u003cp\u003eEach Himalaya heater includes a metal heater guard (rock guard) rail that must remain in place during operation and is engineered with defined clearances from combustible surfaces per Finnleo's installation specifications. The heater should never be operated without its tower fully and properly filled with rocks and the guard rail installed. Three metal safety placards are included with every unit — a CAUTION placard mounted on the interior wall directly above the heater, and WARNING placards mounted on or beside the sauna door at eye level, both required by code for safe operation.\u003c\/p\u003e\n\n\u003ch2\u003eRoom Requirements \u0026amp; Ventilation\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSauna doors must swing outward and use only magnetic, friction, spring, or gravity-loaded closures — no permanent locks or latches\u003c\/li\u003e\n\u003cli\u003eNo electrical receptacles or showers are permitted inside the sauna room\u003c\/li\u003e\n\u003cli\u003eMinimum recommended flooring thickness of 5\/8\"\u003c\/li\u003e\n\u003cli\u003eFresh-air inlet vent located directly below the heater, with an outlet vent positioned lower than the upper bench and roughly two feet above the inlet, sized to UL 875 ventilation standards\u003c\/li\u003e\n\u003cli\u003eRoom air should fully exchange approximately 6 times per hour for proper comfort and heater performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHimalaya rock-tower electric sauna heater (7.0 kW 240V\/1PH, 9.0 kW 240V\/1PH, or 9.0 kW 208V\/3PH)\u003c\/li\u003e\n\u003cli\u003eApproximately 210 lb of sauna rocks\u003c\/li\u003e\n\u003cli\u003eStandard BioWater Technique (BWT) integral water tank with fragrance diffuser\u003c\/li\u003e\n\u003cli\u003eHeater guard (rock guard) rail\u003c\/li\u003e\n\u003cli\u003eWall\/bench mounting bracket\u003c\/li\u003e\n\u003cli\u003eThree metal CAUTION\/WARNING safety placards\u003c\/li\u003e\n\u003cli\u003eInstallation and operating instruction manual\u003c\/li\u003e\n\u003cli\u003eOptional bundling with SaunaLogic2 (Wi-Fi or non-Wi-Fi) control and matching contactor (CB) box sized to heater voltage\/phase\u003c\/li\u003e\n\u003cli\u003eOptional integrated lighting package (3–8 fixtures with splitter and cabling)\u003c\/li\u003e\n\u003cli\u003eOptional Bluetooth audio package\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eMaintenance\u003c\/h2\u003e\n\u003cp\u003eFinnleo recommends wiping down the heater periodically to remove lint and dust, inspecting benches and structural supports annually for dry rot or wear, and removing the rocks once a year to clean them and replace any that are cracked or crumbling. Sauna rooms in daily use should be washed down weekly and aired out between sessions by leaving the door and vents open.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy Finnleo from Us\u003c\/h2\u003e\n\u003cp\u003eFinnleo, built by Sauna360 in Cokato, Minnesota, is one of the most trusted names in authentic Finnish sauna.
