Narvi
Narvi Oy is a Finnish stove maker, and every heater on this page was designed, engineered and made in Finland. What separates a Narvi in a hot room is stone mass: the NC 16 holds 110 pounds of rock, the Narvi 30 holds 143, and the Narvi 50 carries 220. Narvi credits that stone volume for an even bath, and the NC fire chamber is shaped for a cleaner, more efficient burn.
We carry five Narvi stoves, all wood-fired, from the Kuru 14 for 283 to 494 cubic feet up to the 50 kW Narvi 50 for 1,589 to 2,472. The NC is the one that leaves here most often. The chimney is the question buyers bring us on a Narvi: the flue is a 4.5 inch European size, and the Narvi pipe adapter steps it to 6 inch North American pipe. Call (844) 565-1113 and we will size the room with you.
Narvi questions
What size Narvi heater do I need?
Take the room in cubic feet and adjust it the way Narvi manuals do: multiply by 1.5 for log walls or a sauna that sits cold between uses, and add 2.62 to 4.92 cubic feet per square foot of uncovered glass, brick or concrete. The NC 16 covers 283 to 565 cubic feet, the NC 20 covers 353 to 706.
What chimney does a Narvi stove need?
The flue outlet is 4.5 inches, a European size, and it leaves the stove from the top or the back. The Narvi pipe adapter, part 304-128646, is a two-piece interlocking stainless adapter that brings you to the 6 inch double-wall pipe US building suppliers stock.
Are the sauna stones included?
Stones are ordered separately on every Narvi. Stone capacity runs 77 pounds on the Kuru 14, 110 on the NC 16, 132 on the NC 20 and the Kaamos 20, 143 on the Narvi 30 and 220 on the Narvi 50. Narvi split-face stones are olivine diabase, 4 to 6 inches, packed 44 pounds to a box.
What ships in the box, and how long does it take?
Each stove ships by freight with its installation and operation manual and a 2-year limited warranty, and we quote 10 to 14 days to the door on an in-stock model. Firewood goes in at 13 inches, and the installation base has adjustable legs for a sloped floor.

Narvi NC – The ‘Goldilocks of Thermal Mass’
Price range: $1,695.00 through $2,495.00Experience the most efficient sauna stove on the planet, all in a modern package that looks great in any sauna. We call this stove the ‘goldilocks’ of thermal mass. If you have too little rocks, the sauna will heat fast but may feel harsh. Too many rocks and it can take hours to heat the room. The Narvi NC Series is the perfect balance of efficiently heating the room while providing a soft heat and steam.
This stove requires a fraction of the wood as less efficient stoves, achieving a complete burn that’s good for you, your neighbors, and the planet. And while most Finnish sauna companies are shipping production to China, this heater is 100% designed and built by people who live and breathe sauna in Finland.

Narvi Flue 15 | Kota Basic Insulated Chimney Kit for 4.7 in Sauna Stove Flues
$995.00Narvi’s insulated modular chimney for wood-burning sauna stoves, model Kota Basic Flue 15 black light 255/120×1500 with a straight rubber flange. The insulated flue is 10 in. in diameter and the uninsulated stainless start pipe below it is 4.7/4.8 in, which Narvi states is “compatible with all sauna stoves that have a smoke output diameter of 4.7 in.” Zinc-coated steel casing in black heat-resistant paint, CE certified, 59.5 lb.
Narvi Protective Wall 650×1150
$380.00With the help of protective walls, the sauna heater can be safely placed closer to the sauna walls.

Narvi Installation Base 550×620 Black | Adjustable Floor Base for Narvi Wood Stoves
$357.00A rustproof steel base, 21.7 x 24.4 in., with legs that adjust from 2.8 to 3.7 in. Narvi’s manuals make a base mandatory in two named cases: a floor of combustible material or a tiled floor, and any floor with underfloor heating pipes or cables beneath the stove. On a sloping floor the adjustable legs are also what levels the stove. 16.5 lb, black, designed and made in Finland.
Narvi Stone Cage 250×400 Black | Flue-Mounted Stone Basket for Narvi Wood Stoves
$207.00A black rustproof steel cage, 9.8 in. across and 15.8 in. tall, that holds a column of stones around the connective flue above a Narvi wood stove. Narvi’s reasoning: the heat of the flue gets used better, and the steam lasts longer because the water flows from the cage down onto the heater’s own stones. Cages can be stacked. Stones are not included, and the 4–6 in stones Narvi specifies for the heater basket are too large for the cage.
Narvi Pipe Adapter 163724 | 4.5″ Euro to 6″ USA Chimney Adapter for Narvi Wood Stoves
$169.00Narvi’s wood stoves leave the factory with a 4.7 in connective flue, the figure printed in the technical data of the NC, Kuru, Kaamos 20 and Narvi 30 manuals. US wood-stove pipe is nominal 6 in. This two-piece interlocking stainless adapter is the transition: 4.72 in. inside diameter at the small, stove-side end, and 6.14 in. inside diameter at the large, chimney-side end. The Narvi 50 uses a 5.7 in flue and takes a different part.
