    How it scores Our rating, metric by metric Excellent, 4.5 of 5
    1. Heat & steam 25% of the rating 5 of 5

      A 9 kW element set around an open column of 200 lb of stones for 141 to 494 ft³, which lets you choose soft or sharp steam; Harvia’s manual calls 149 to 167 °F a suitable bathing temperature and a dealer lists a 104 to 194 °F control range.

    2. Build 15% of the rating 4 of 5

      A steel pillar with built-in dials and no painted surface stated, but Harvia calls it steel while dealers say stainless, and Harvia does not state the element material.

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

      The model pattern HPC(S)9U1HB is in Intertek’s UL 875 and CSA listings, and the page gives clearances of 4 in in front, 1.2 in at the sides and 35 in to the ceiling.

    4. Durability 20% of the rating 3 of 5

      The manual gives a one-year guarantee on all parts, the dealer says two years and Almost Heaven says five on non-element parts; spare parts are numbered in the manual.

    5. Value 15% of the rating 5 of 5

      About $1,920 for a working set with built-in controls and stones, the lowest of the heaters here, with no separate controller to buy.

    The rating, 4.5 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 (authorized Harvia dealer) (opens in a new tab) approx. $1,625 for the heater with built-in controls; approx. $1,920 with five 20 kg boxes of stones. Harvia sells through dealers and shows no price on its own site. The price above is this dealer’s, and its page calls it an authorized Harvia dealer.
    • Amazon (opens in a new tab) approx. $1,720 with five boxes of stones. Item model number H-HPCS9U1HB, the same model code. Sold and shipped by BathingBrands, a sauna wholesaler, not by Harvia or Amazon. Cheaper than the dealers’ stone packages.
    • Haven of Heat (retailer) (opens in a new tab) approx. $1,920 with five boxes of stones ($1,625 for the heater alone). The 9 kW size of the Cilindro Half Series with built-in knob controls (HPCS9U1HB), stones included. The heater alone is a separate page. Its page lists a 2-year consumer warranty.
    • SaunaKits.com (retailer) (opens in a new tab) approx. $1,920 with five boxes of stones. The PC90 package with five boxes of Harvia AC3000 stones. The heater alone is a separate page at $1,625.

    Who tested it What each test found, and who paid for it 1 test
    • Paid certification Intertek (ETL directory, for Harvia Finland Oy)

      Lists sauna heating appliances HPC or SPC, optionally (S), then 6 to 11, U1 or U3, then H, H(Q) or HB, to UL 875, with a sister listing to CAN/CSA E60335-2-53. The dealer’s part number HPCS9U1HB fits the pattern. It covers the heater, not the stones or the room, and shows no certificate number or date. 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
    Which warranty applies?
    Three figures circulate. The manual (opens in a new tab) says one year on all parts for family use and 3 months for communal use. Three dealers (Finnish Sauna Builders, Haven of Heat and SaunaHeaters) list 2 years for consumer use. Almost Heaven’s warranty page (opens in a new tab) says the Harvia heaters it sells carry 1 year on the elements and 5 years on other parts. Get the term in writing from the seller.
    Which stones are safe, and how many?
    The manual says to use angular split-face stones of 5 to 10 cm, naming peridotite, olivine-dolerite and olivine as suitable, and not to use light porous ceramic “stones” or soft soapstone. It warns that a heater run without stones, or with the stone space under-filled, is a fire risk, and that stones crumble and should be rearranged at least once a year.
    Does it smell the first time?
    Yes, by the manual’s own account: the heater and the stones give off a smell on first heating, and the sauna room should be ventilated well.
    Does it have an app or Wi-Fi?
    No. This version has dials and a timer built in. Harvia’s Wi-Fi control comes with its separate-control heaters, not this one.
    Why we chose it What put it on our list 4 points
    • The listing matches the model. Intertek’s ETL directory lists Harvia heaters “HPC or SPC, optionally (S), 6 to 11, U1 or U3, then H, H(Q) or HB”, and the Cilindro’s part number HPCS9U1HB fits it.
    • A big stone mass. Harvia’s page gives 200 lb of stones, 5 to 10 cm, and its manual gives 141 to 494 ft³ for the 9 kW size. Harvia says to throw water in the middle of the pillar for gentle steam or on top for sharp steam.
    • The controls are built in: dials and a timer, so there is no control box to buy, wire or replace.
    • Plain rules in the manual: stone type and size, how often to rearrange them, the 30-minute limit and no alcohol.
    Trade-offs What to weigh before you buy 4 points
    • The guarantee in Harvia’s manual is one year. A longer term is quoted by the dealer, and the sources disagree.
    • It needs a licensed electrician: a 240 V circuit at 37.5 A with 8 AWG copper wire. The stones are a separate purchase of about $295.
    • Harvia lists the main material as steel. The dealer calls it stainless steel; we could not confirm which.
    • The dials are mechanical. If you want a schedule or a phone app you need Harvia’s separate-control Cilindro (the E version) and a Xenio control, which cost more.
    What to know Details worth knowing first

    A traditional sauna makes steam when water hits hot stones. Finnish saunas, the kind the long-term studies followed, run at 80 to 100 °C with 10 to 20% humidity (review (opens in a new tab)). The Cilindro is a stone-heavy heater for that job: 200 lb of stones around three 3,000 W elements, with the controls built into the body.

    We could check the listing. Intertek’s ETL directory lists Harvia heaters by model pattern, and HPC(S)9U1HB fits it, in both the US and Canadian listings. What we could not settle is the warranty: the manual says one year, the dealer says two, and Almost Heaven says five on most parts. Ask for it in writing.

    Buy the stones the manual describes, split-face olivine, peridotite or olivine-dolerite at 5 to 10 cm, and have an electrician size the circuit. Ask a doctor first if you have a heart condition or are pregnant.

    How Harvia Cilindro PC90 9 kW Electric Sauna Heater (240 V, built-in controls) measures up against our sauna heaters criteria
    What we checked What we found
    Stones and steam Maker’s claim Harvia’s page gives 200 lb of 5 to 10 cm stones in an open pillar. Its manual gives 141 to 494 ft³ for the 9 kW size and calls 149 to 167 °F a suitable bathing temperature. These are maker figures; we have no measured temperatures.
    Safety listing Verified HPC(S)9U1HB fits a model pattern in Intertek’s ETL directory (UL 875) and in its sister cETL listing (CAN/CSA E60335-2-53). Harvia’s US page also says ETL. The listings show no certificate number or date.
    Build and materials Not verified Harvia lists the main material as steel; dealers and the Amazon listing say stainless steel, and two dealers add stainless elements. Harvia does not state the heating elements’ material.
    Wiring and clearances Maker’s claim 240 V, 1 phase, 37.5 A, 8 AWG copper (the dealer and the manual’s table). Clearances: 4 in in front, 1.2 in at the sides, 35 in to the ceiling and 1.2 in to the floor.
    Recalls and notices Verified A search of the US Consumer Product Safety Commission recall data on 2026-10-23 found no recall naming Harvia, and California’s Prop 65 notice search found none naming Harvia.
    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.
