    How we evaluated it

    How it scores Our rating, metric by metric Fair, 3.3 of 5
    1. Heat & steam 25% of the rating 5 of 5

      A 13 kW wood fire under 198 lb of stones for 212 to 459 ft³, which is more stone than most wood stoves hold and needs no electricity.

    2. Build 15% of the rating 3 of 5

      A 5 mm stainless flame tamer, but the manual says the casing is painted, which contradicts a dealer’s “no chemicals or coatings”, and the paint smells on first firing.

    3. Safety listing 25% of the rating 2 of 5

      No North American listing exists to find; HUUM’s manual declares EN 15821:2010 results (fire safety, surface temperature and carbon monoxide passed, hazardous emissions not determined) and a specialist must connect the chimney.

    4. Durability 20% of the rating 3 of 5

      HUUM’s terms give wood-burning heaters 3 years in private use and exclude door glass, the ash grate and stones, a dealer says 5 years, and US claims now go to HUUM in Estonia.

    5. Value 15% of the rating 3 of 5

      About $2,150 for the stove plus about $560 for stones (an Amazon seller bundles the stones for $2,530 in all) and a chimney of your own, with no electrician needed for the heater.

    The rating, 3.3 of 5, is the weighted average of these scores. See how we rank sauna heaters and our standard.

    Where to buy Stores and the prices we saw 4 stores
    • Finnish Sauna Builders (retailer) (opens in a new tab) approx. $2,150 for the stove; approx. $560 for the 198 lb stone package. A retailer, not the maker. Its page says it can no longer handle HUUM warranty claims, which go to HUUM in Estonia, and repeats “treated only with natural oils – no chemicals or coatings”, which the manual contradicts.
    • Amazon (opens in a new tab) approx. $2,530 with 198 lb of rounded olivine stones. Sold and shipped by BathingBrands, a sauna wholesaler, not by HUUM or Amazon. Chimney not included. The listing repeats “treated only with natural oils” and a 3-year warranty; HUUM’s terms cover products sold by HUUM or its authorized dealers, so ask whether the seller is one.
    • Haven of Heat (retailer) (opens in a new tab) approx. $2,150 for the stove (stones and chimney sold separately). Its page lists a 3-year warranty, as HUUM’s terms do, and a cast iron furnace door, where other sellers say stainless. It does not repeat the natural-oils line.
    • The Sauna Place (retailer) (opens in a new tab) approx. $2,150 for the stove. Stove only, same price as the dealers above; stones and a chimney are separate.

    Prices as we saw them on October 23, 2026. They change often. These links carry no tracking code and earn us nothing.

    What it’s made of What touches your food, water, skin or air 4 materials
    1. Steel furnace and casing; the manual says “steel frame” and that the outer casing is treated with heat-resistant paint, which smells on first heating
    2. 5 mm (0.2 in) stainless steel flame tamer; four sellers call the body and furnace door stainless, which the manual does not say, and Haven of Heat says the door is cast iron
    3. A stone cage that holds 90 kg (198 lb) of 5 to 10 cm sauna stones, not included
    4. A flue connection for a T600-rated chimney, installed by a specialist; not included
    Who tested it What each test found, and who paid for it 1 test
    • Maker’s own test HUUM (declared performance to EN 15821:2010, in its US manual)

      The manual’s table reports fire safety, exhaust gases, surface temperature, cleanability and mechanical resistance as passed, carbon monoxide at 13% O2 as passed, total efficiency of about 67%, minimum chimney draught of 12 Pa, and “NPD” (no performance determined, as the French text puts it) for emission of hazardous compounds. It does not name a test lab; HUUM’s certificates page mentions an SZU certificate from a Czech test institute without saying which products it covers. Open ↗ (opens in a new tab)

    Who paid, and why it matters
    • Independent The tester took no money from the maker for it: a consumer group, a journalist, a university or a regulator.
    • Paid certification An outside lab or certifier tested or listed it, and the maker paid for that.
    • Maker’s own test A lab report or certificate of analysis the maker commissioned and published.

    A certification is a floor, not a verdict: it checks what its program checks and nothing else. We weigh tests by someone with no stake in the result most.

    What people ask Worries raised online and elsewhere, and what we found 4 questions
    Is it listed for use in North America?
    We found no UL, ULC, CSA or ETL listing for it. Intertek’s ETL directory has no entry for HUUM, Kuuma’s maker Lamppa, Narvi or Kastor, and its 11 Harvia entries are electric heaters and controls; a web search for sauna stoves listed to UL 1482 or ULC S627 found none. Seller pages and Harvia’s US page for its Legend wood stoves show CE (and EAC) marks only, so the gap is not special to HUUM. HUUM’s own certificates page lists CE, SZU (a Czech test institute), ISO 9001 and, for the HIVE Flow only, BImSchV II, none naming the Wood 13. The manual says installation must follow local and European standards including EN 15821:2010 and that a specialist must connect the chimney. Ask your building department what it accepts before you buy.
    Is it really “treated only with natural oils”?
    Four sellers (Finnish Sauna Builders, SaunaKits, SaunaHeaters and an Amazon seller) say so, and Finnish Sauna Builders adds “no chemicals or coatings”. HUUM’s own US and EU product pages do not make the claim. HUUM’s own manual (opens in a new tab) says the outer casing carries a heat-resistant paint that gives off an unpleasant odor on first firing, and advises burning the stove outdoors first.
    Who services it in the US?
    Finnish Sauna Builders’ page says it is no longer authorized to handle HUUM parts and warranty claims, which must go to HUUM in Estonia. HUUM’s terms (opens in a new tab) give 3 years for wood-burning heaters in private use, not the 5 years that Finnish Sauna Builders and SaunaKits list (Haven of Heat and SaunaHeaters list 3), exclude door glass, the ash grate and the stones, and cover only products sold by HUUM or its authorized dealers.
    What about smoke and carbon monoxide?
    The manual reports carbon monoxide as passed under EN 15821 and says the flue gases must go into a separate flue and that forced extract ventilation can starve combustion. It gives no figure for hazardous compounds. Install a carbon monoxide alarm and have a specialist check the draught.
    Why we chose it What put it on our list 3 points
    • The stone mass: 90 kg (198 lb), which the maker says is more than most wood stoves hold, for long-lasting soft steam.
    • A 5 mm stainless steel flame tamer, and a heat exchanger option, per the maker.
    • The maker publishes a US manual with its EN 15821 test table, its safety distances and its chimney class (T600).
    Trade-offs What to weigh before you buy 4 points
    • No UL, ULC or CSA listing: only a declared EN 15821 result, with hazardous emissions undetermined. Check local code.
    • The casing is painted, according to the manual, and smells on first firing, which the “treated only with natural oils” copy at four sellers does not say.
    • A chimney, a CO alarm and a specialist’s connection are extra, and the stones cost about $560.
    • Warranty: 3 years in HUUM’s terms, 5 years on two sellers’ pages, and claims go to HUUM in Estonia.
    What to know Details worth knowing first

    A wood-fired stove is the oldest way to make a sauna, and the HIVE Wood 13 holds 198 lb of stones, which gives soft, long-lasting steam. It needs no electricity, only a proper chimney and a specialist to connect it.

    The safety question is the listing. We found no UL, ULC or CSA listing for it, and a web search found no wood-burning sauna stove listed to UL 1482 or ULC S627. HUUM’s manual declares results to the European standard EN 15821:2010, with fire safety and carbon monoxide passed and hazardous emissions undetermined, and names no lab. Ask your building department what it accepts, and fit a carbon monoxide alarm.

    Read the manual, not only the sellers’ pages. Four of them say the stove is treated only with natural oils, and one adds no chemicals or coatings; the manual says the casing is painted and smells on first firing, and advises burning it outdoors first. HUUM’s terms give three years, and US claims go to HUUM in Estonia.

    What we checked Each claim, and how sure we are of it 5 checks
    Tested by
    HUUM (declared EN 15821:2010 results; no independent lab named)
    How HUUM HIVE Wood 13 Wood-Burning Sauna Stove measures up against our sauna heaters criteria
    What we checked What we found
    Stones and steam Maker’s claim 13 kW; 90 kg (198 lb) of 5 to 10 cm stones; rooms of 6 to 13 m³ (212 to 459 ft³), per the maker.
    Safety listing Not verified No North American listing found. The manual declares EN 15821:2010 results (fire safety, surface temperature and CO passed; efficiency about 67%; hazardous-compound emissions “NPD”) without naming a lab.
    Build and materials Maker’s claim 5 mm stainless flame tamer per the maker. The manual says the outer casing is painted with heat-resistant paint; four sellers say stainless steel body and door and “natural oils” only, which we could not confirm.
    Wiring and clearances Maker’s claim No electrical supply is needed. The manual gives safety distances (about 250 mm to the side and 900 mm in front per the dealer), a T600 chimney, a 115 mm flue and a required connection by a specialist.
    Recalls and notices Verified A search of the US Consumer Product Safety Commission recall data on 2026-10-23 found no recall naming HUUM, and California’s Prop 65 notice search did not find a notice naming HUUM.
    What the labels mean
    • Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
    • Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
    • Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.
