The Narvi Luosto Wood-Burning Sauna Stove is a Finnish wood-burning sauna stove from Narvi. Narvi EN 15821 nominal space-heating output: 16 kW. Room range on narvi.fi: 8–20 m³ (about 283–706 cu ft). Stones and the flue are sold separately. This is not an electric heater. This is the Luosto stove — the round enamelled cabinet — not the 250×400 flue cage accessory.
How it heats
This is a continuously heated wood-burning sauna stove, not an electric heater. You load dry firewood, run the fire while you bathe, and throw water on the rocks for löyly. Smoke leaves through a 119 mm outlet — top or rear on most of these SKUs (cap the unused opening). Connect it to a masonry chimney or Narvi’s Kota 15 steel flue (sold separately). Clearances in the IOM are to combustibles; a Narvi installation base is required on combustible floors and over underfloor heat. Stones are sold separately. This listing is the stove.

Sizing
Match stove output to insulated interior volume. Glass, stone, tile, or thin walls eat heat. Chimney, clearances, and combustion air follow the Narvi manual and local code — we do not invent UL or a US 6-inch Class A kit. Email hello@selfcaresaunas.com if you want a second look at the room.
Code, UL, and who decides the flue
A licensed chimney installer and the authority having jurisdiction decide the flue for your building. Narvi prints CE / T600 on the Kota 15 pages we cite. Those pages do not print a UL listing. We will not invent one. This is not a US 6-inch Class A kit.
Email hello@selfcaresaunas.com with roof type (flat vs pitched) and ceiling height before you order pipe.
FAQ
Are stones included?
No. Luosto stone load in Narvi’s table is 35 kg / about 77 lb. About 2 boxes of the 20 kg / 44 lb Narvi 10–15 cm carton (narvi-sauna-stones-split-10-15 split-face, or rounded narvi-sauna-stones-rounded-10-15). Round up so you are not short.
Is a chimney included?
No. Order Kota 15 (narvi-kota-basic-flue-15) or have a masonry flue the installer accepts. CE / T600 on Narvi’s Kota 15 pages — not UL.
Is this electric?
No. Wood-burning only. There is no Narvi electric heater in this authorized list.
Is this a complete sauna?
No. Stove only.
US 6-inch Class A?
No. Outlet is 119 mm. The 6-inch adaptor SKU (narvi-pipe-adaptor-6in) is a pipe adaptor, not a listed Class A kit. Installer and AHJ decide.
Chimney water tank?
Optional. 30 L stainless tank narvi-chimney-watertank-30l hangs on a 122 mm connecting flue at least 600 mm long. Do not stack it with the 250×400 stone cage — they occupy the same flue.
