Feed\u003c\/h2\u003e\n\u003cp\u003eThe Harvia Legend 150 SL is a 16kW wood-burning sauna stove for rooms from 212 to 459 cubic feet, built around the SL exterior-feed configuration of the Legend platform. The fire chamber extends through the sauna wall so wood is loaded from an adjacent room or outdoors - the cast-iron glass door faces outward, creating a live fireplace view for the person in the adjacent room while bathers inside the sauna enjoy the full 16kW heat output and the soft, humid steam from 264 lbs of AC3020 stones. Harvia describes this as a comfortably moist sauna bath - the large stone mass relative to the room size produces gentle, deeply humid steam that is characteristic of smaller Legend installations. The reversible door direction is set during installation to suit the room layout. The split-air grate structure directs part of the combustion air to the upper fire chamber for cleaner, more efficient burning. Adjustable legs simplify levelling. Flue: 115mm (4.5\") European standard - a 6\" North American adapter is required and sold separately. 264 lbs AC3020 stones (6 boxes, 10-15 cm) required and sold separately. Pallet delivery - scheduled freight appointment required. CE and EAC certified. Made in Finland by Harvia.\u003c\/p\u003e\n\u003ch4\u003eSL exterior feed - sauna heat inside, fireplace view outside\u003c\/h4\u003e\n\u003cp\u003eThe Legend 150 SL's defining feature is the through-wall fire chamber that separates the experience of the sauna from the experience of managing the fire. The firebox and cast-iron glass door face the adjacent room - a lounge, relaxation space, or exterior area. Wood is loaded from outside the sauna at all times. The fire is visible and tended from outside. Inside the sauna, bathers receive 16kW of radiant wood heat and the steam from 264 lbs of stones without the sauna door ever opening for firewood. Harvia's own description is direct: the Legend 150 SL is the right choice for people who want to conveniently heat their sauna from another room or outside the building. For a cabin sauna with an adjoining relaxation room, a sauna building where the fire must be loaded from outdoors, or any layout where exterior wood loading is the preferred operational mode, the 150 SL is purpose-built for the task.\u003c\/p\u003e\n\u003ch4\u003e264 lbs of stones for a 212-459 cu ft room - comfortably humid steam\u003c\/h4\u003e\n\u003cp\u003eThe Legend 150 SL carries 264 lbs (120 kg) of AC3020 stones for a room range of 212 to 459 cu ft. The ratio of stone mass to room volume is deliberately generous - the large stone load relative to the smaller room size produces the comfortably moist steam quality that Harvia specifically attributes to this model. The stones accumulate heat throughout the fire and hold it long after the fire dies down. The open structure of the stone compartment allows water to be thrown on the entire outer surface of the stone bed, not just a single point - the steam is distributed across the full stone mass and rises evenly into the sauna room. The heat retained in the large stone load allows water to be added at lower temperatures, sustaining humid steam without the fire needing to be at full intensity.\u003c\/p\u003e\n\u003ch4\u003eSplit-air grate, compact clearances, and reversible cast-iron glass door\u003c\/h4\u003e\n\u003cp\u003eThe Legend 150 SL fire chamber uses a split-air combustion grate that routes part of the air supply to the upper fire chamber for more complete combustion, reduced creosote output, and a longer fire chamber lifespan. Safety clearances to combustible materials are modest for a 16kW stove: 7.87\" at both sides, 9.84\" at the back, 19.69\" at the front. To non-combustible materials, the side and back clearances reduce to 3.94\". The reversible cast-iron glass door is set to open left or right during installation with no need to order a handed configuration at purchase. Adjustable legs allow the stove to be levelled on any floor condition. A licensed or certified chimney professional is recommended for all flue installations and for correct preparation of the wall penetration for the SL fire chamber extension.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-hook\"\u003e16kW wood-burning sauna stove for rooms from 212 to 459 cubic feet.

Inside the sauna: 16kW of radiant wood heat, soft and humid steam from 264 lbs of stones, and the atmosphere of a traditional Finnish wood-fired sauna. In the adjacent room: the cast-iron glass door provides a direct live view of the burning fire, with the warmth and ambience of a working fireplace. Both experiences run simultaneously from a single fire tended from one side - outside the sauna - without any interaction with the sauna interior. For a cabin sauna with a lounge, a sauna building where the fire is loaded from outdoors, or any layout with two rooms sharing a wall, the 150 SL delivers both without compromise.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-feat\"\u003e\n\u003cdiv class=\"ls-feat-title\"\u003eComfortably moist steam - 264 lbs of stones for a smaller sauna\u003c\/div\u003e\n\u003cp\u003eHarvia specifically describes the Legend 150 SL as delivering comfortably moist steam for smaller saunas - a deliberate reference to the ratio of stone mass (264 lbs) to room size (212-459 cu ft). The generous stone load relative to the room produces deeply humid steam that is characteristic of smaller, more intimate sauna bathing. The open stone compartment structure allows water to be thrown on the full outer surface of the stone bed, distributing steam evenly across the room rather than from a single pour point. The heat stored in the large stone mass allows water to be added even at lower temperatures, sustaining soft steam throughout the session without the fire needing to be at peak output.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-feat\"\u003e\n\u003cdiv class=\"ls-feat-title\"\u003eUndisturbed sessions - wood loaded from outside\u003c\/div\u003e\n\u003cp\u003eWood loading, fire adjustment, and firebox access all happen from outside the sauna room. The sauna door never needs to open for firewood - heat is retained, the session is uninterrupted, and the bathing atmosphere inside the sauna remains completely undisturbed. In a cabin sauna with an adjoining lounge, one person can tend the fire from the lounge while bathers inside are in full session. The reversible door direction is set at installation - left or right swing is decided based on room layout, not at purchase. Adjustable legs allow the stove to be levelled precisely on any floor surface during installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-feat\"\u003e\n\u003cdiv class=\"ls-feat-title\"\u003eSplit-air grate - cleaner burn, longer stove life\u003c\/div\u003e\n\u003cp\u003eThe Legend 150 SL fire chamber uses Harvia's split-air combustion grate, which routes a portion of the combustion air supply to the upper fire chamber above the primary burn zone. Secondary air supports more complete combustion of gases, reducing smoke output and creosote buildup in the flue. The cleaner burn means lower chimney maintenance frequency and better air quality from the flue output. Harvia credits the split-air grate design with directly extending the fire chamber's operational lifespan - a meaningful benefit for a stove that is expected to serve for decades of seasonal or year-round use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-feat\"\u003e\n\u003cdiv class=\"ls-feat-title\"\u003eCompact safety clearances for flexible bench placement\u003c\/div\u003e\n\u003cp\u003eThe Legend 150 SL's safety clearances to combustible materials are modest for a 16kW stove: 7.87\" at both sides and 9.84\" at the back. These smaller than usual distances from side and back surfaces are specifically noted by Harvia as enabling more flexible bench placement within the sauna room. To non-combustible materials the clearances reduce further to 3.94\" at both sides and back. The optional WL200 protective sheath (sold separately) can be fitted to reduce clearances even further when required by the specific room layout. For a small sauna room in the 212-459 cu ft range, this clearance flexibility directly impacts how much usable bench area can be positioned relative to the stove.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-feat\"\u003e\n\u003cdiv class=\"ls-feat-title\"\u003eLegend Series platform - 150 SL and related configurations\u003c\/div\u003e\n\u003cp\u003eThe WK150LDSL is the exterior-feed SL variant of Harvia's Legend 150 platform.

For the 212-459 cu ft range with exterior feed and the comfortably moist steam quality of the 150 platform, the Legend 150 SL is the purpose-built specification.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cimg style=\"margin-bottom: 16px; float: none;\" alt=\"Harvia Legend 150 SL exterior feed vs Legend 150 interior feed vs Legend 300 larger room comparison\" src=\"https:\/\/mediriser.com\/cdn\/shop\/files\/harvia_legend_150_8ce9eb4c-628f-4508-89f1-7e4440a59732.jpg?v=1780861024\u0026amp;width=800\" class=\"ls-brand-img\"\u003e\n\u003c\/div\u003e\n\u003chr class=\"ls-divider\"\u003e\n\u003ch3\u003eManuals and Documents\u003c\/h3\u003e\n\u003cdiv class=\"ls-manual\"\u003e\n\u003cdiv class=\"ls-manual-item\"\u003e\n\u003ch6\u003eInstallation and Operation Manual\u003c\/h6\u003e\n\u003ca href=\"https:\/\/prod-cms.bathingbrands.com\/sites\/default\/files\/2026-06\/Harvia-Legend-Sauna-Heater-IOM.pdf\" class=\"ls-doc-link\" target=\"_blank\"\u003e \u003csvg width=\"14\" height=\"14\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"\u003e\u003cpath d=\"M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z\"\u003e\u003c\/path\u003e\u003cpolyline points=\"14 2 14 8 20 8\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e Installation and Operation Manual (PDF) \u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-manual-item\"\u003e\n\u003ch6\u003eSafety Sheet\u003c\/h6\u003e\n\u003ca href=\"https:\/\/prod-cms.bathingbrands.com\/sites\/default\/files\/2022-03\/Harvia-WK150LDSL-Safety.pdf\" class=\"ls-doc-link\" target=\"_blank\"\u003e \u003csvg width=\"14\" height=\"14\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"\u003e\u003cpath d=\"M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z\"\u003e\u003c\/path\u003e\u003cpolyline points=\"14 2 14 8 20 8\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e Safety Sheet (PDF) \u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-manual-item\"\u003e\n\u003ch6\u003eData Sheet\u003c\/h6\u003e\n\u003ca href=\"https:\/\/prod-cms.bathingbrands.com\/sites\/default\/files\/2026-06\/Harvia-WK150LDSL-Sauna-Heater-Data-Sheet.pdf\" class=\"ls-doc-link\" target=\"_blank\"\u003e \u003csvg width=\"14\" height=\"14\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"\u003e\u003cpath d=\"M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z\"\u003e\u003c\/path\u003e\u003cpolyline points=\"14 2 14 8 20 8\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e Data Sheet (PDF) \u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-manual-item\"\u003e\n\u003ch6\u003eDeclaration of Performance\u003c\/h6\u003e\n\u003ca href=\"https:\/\/prod-cms.bathingbrands.com\/sites\/default\/files\/2022-03\/Harvia_Legend_Series-DOP.pdf\" class=\"ls-doc-link\" target=\"_blank\"\u003e \u003csvg width=\"14\" height=\"14\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"\u003e\u003cpath d=\"M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z\"\u003e\u003c\/path\u003e\u003cpolyline points=\"14 2 14 8 20 8\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e Declaration of Performance (PDF) \u003c\/a\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"ls-manual-item\"\u003e\n\u003ch6\u003eStone Requirements\u003c\/h6\u003e\n\u003ca href=\"https:\/\/prod-cms.bathingbrands.com\/sites\/default\/files\/2026-02\/Harvia%20Stone%20Requirements%2002.27.25.pdf\" class=\"ls-doc-link\" target=\"_blank\"\u003e \u003csvg width=\"14\" height=\"14\" viewbox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2\"\u003e\u003cpath d=\"M14 2H6a2 2 0 0 0-2 2v16a2 2 0 0 0 2 2h12a2 2 0 0 0 2-2V8z\"\u003e\u003c\/path\u003e\u003cpolyline points=\"14 2 14 8 20 8\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e Stone Requirements (PDF) \u003c\/a\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003ch3\u003eWarranty\u003c\/h3\u003e\n\u003cdiv class=\"ls-warranty\"\u003e\n\u003ch5\u003e2-year limited warranty (consumer use)\u003c\/h5\u003e\n\u003cp\u003eThe Harvia Legend 150 SL is covered by Harvia's \u003cstrong\u003e2-year limited warranty\u003c\/strong\u003e from the date of purchase for consumer use.
