It's a 6 kW wall-mounted electric sauna heater in polished stainless steel, with no onboard controls — it runs from a separate Xenio wall panel. The KIP series is Harvia's practical workhorse line: industrial-grade serviceable elements, direct rock-to-element contact, and a straightforward install.

Rooms from 170 to 300 cubic feet. That's the manufacturer's rating and it's worth staying inside it — an undersized heater runs flat out and wears early, an oversized one short-cycles and never settles.

Length × width × height in feet. A 6' × 6' room with a 7' ceiling is 252 cubic feet, comfortably inside this heater's range. If you're near either end of the band, send us your dimensions and we'll check it properly.

Yes. Glass sheds heat faster than insulated timber, so a glass-fronted room behaves like a larger one. Tell us your glass area before you order and we'll size against it rather than raw volume.

Controls, and nothing else. The W has no onboard controls and requires a separate Xenio wall panel, sold separately. The B has its controls built into the heater. Same 6 kW output, same room range, same body, same stone capacity.

The B is simpler and cheaper all-in if you're happy setting the sauna at the heater itself. The W costs less as a unit but needs the controller on top, so it lands higher — what you get for that is a wall panel outside the hot zone, digital control, and timer functions. If you want to set the sauna without reaching into a hot room, take the W.

The Xenio CX170, single-phase version, is the specified control for this heater. Ask us and we'll quote heater and controller together so nothing arrives half-finished.

Those are specified for the Club, Spirit, Cilindro and Virta series rather than the KIP. Send us your heater part number and we'll confirm the right controller — this isn't a place to guess, because a mismatched controller either won't work or won't be covered.

Ask us about Wi-Fi capability with the CX170 pairing before you buy. If app control and scheduling matter to you, say so up front — there are heaters in the Harvia range built specifically around that, and we'd rather point you at the right one than have you discover a limitation afterwards.

240V single phase, drawing 25 amps on a 30-amp line fuse. It's hardwired — no plug. A three-phase version is also available if that's what your building has.

Possibly, if you're replacing another 6 kW heater — the draw is the same as most 6 kW units. Send us a photo of your breaker and the old heater's rating plate and we'll confirm before you spend anything.

No, and this matters. Harvia heaters should not be run on GFCI — it causes nuisance tripping and voids the warranty. If your electrician suggests one, point them at the installation manual before anything gets wired.

Yes, any licensed electrician can. Give them the manual before they start — the circuit requirements and the no-GFCI note are both in it, and it saves a return visit.

16" wide × 11" deep × 24" high (410 × 280 × 600 mm).

29.7 lbs empty. With 44 lbs of stones loaded it's around 74 lbs on the wall, so it needs to be mounted into solid framing rather than just cladding.

Corrosion resistance. A sauna is a hot, humid room and steel that isn't protected will eventually show it. The polished stainless casing is durable and holds its appearance, which is why it's the traditional finish for sauna heaters.

Minimum clearances to walls, benches and ceiling are in the installation manual and they're a fire-safety requirement, not a suggestion. Check them before you finalise bench placement — moving a bench afterwards is far more work than moving it on paper.

Conventionally on the wall by the door, so heat rises across the benches rather than straight up the wall behind you. Layout genuinely affects how the room feels, so if you're building from scratch, ask us before you frame it.

No. The KIP60W needs one box of Harvia AC3000 split-face stones, 5–10 cm, ordered separately. The heater will not run safely without them.

One box covers the 44 lb stone capacity. Harvia suggest buying a second so you can hand-pick the best-fitting pieces, though that's optional and adds freight on something heavy.

The KIP is specified for split-face AC3000. The rounded R-991 stones are designed for the Spirit series and its much larger stone column. Stick to what the manual specifies.

Only proper sauna stones. Never river rock, granite, or decorative landscape stone — ordinary rock can crack or explode when water hits it at temperature.

Rinse them first, then stack loosely so air moves freely between them — never wedge them tight or force them around the elements. The manual shows the correct arrangement. Packing too densely restricts airflow and shortens element life.

Inspect them once a year. They break down with repeated heating and cooling, and crumbling stones choke airflow through the heater. Restack as they settle, replace when they start falling apart. It's the cheapest thing you can do to extend the life of the heater.

Typically 30 to 45 minutes for a well-insulated room in its size range, though a cold room in winter takes longer.

Maximum setting is 194°F (90°C), a traditional Finnish sauna temperature. Most people run between 160 and 185°F.

Yes — that's the point of a traditional heater. Ladle water over the stones for löyly. Plain water, a ladleful at a time, never poured directly onto the elements.

Only products made for sauna use, diluted in the water bucket rather than poured neat on the stones. Undiluted oils can scorch, stain the stones, and in some cases ignite.

The stones sit directly against the heating elements rather than being separated by a shield. Heat transfers into the stone mass more efficiently, which is what gives a traditional heater its steam response when you ladle water.

Yes. Harvia builds the KIP with industrial-grade serviceable elements, and parts are stocked across the US. That's a real advantage over heaters that have to be replaced whole when one element fails.

Polished stainless steel casing with industrial-grade serviceable elements rather than sealed ones.

Yes — the KIP60W is available in black as well as stainless. The black version has a dual-wall casing that stays cooler to the touch, and it costs a little more. Worth considering if children will use the sauna or if people pass close to the heater.

The heater, the installation and operation manual, and a 2-year consumer-use warranty. Stones, the Xenio controller and any wiring materials are separate.

Two years for consumer use, covering defects in materials and workmanship. Note that's longer than the black version of the same heater, which carries one year — worth knowing if warranty length is a factor in the finish decision. Heating elements and stones are normally excluded as wear items; ask us for the current written terms before you order.

The warranty above is for consumer use. If this is going into a gym, spa, hotel or club, tell us — commercial installations have different warranty terms and often different heater recommendations, and we handle those projects regularly.

Yes — UL listed, and it also carries CE and EAC marks. Your electrical inspector will want to see the UL listing.

Designed, engineered and manufactured in Finland.

Same heater, one step up in output. The 8 kW covers 250 to 425 cubic feet against this one's 170 to 300, and draws 33.3 amps on a 40-amp fuse against 25 amps on a 30-amp fuse. If your room is under 300 cubic feet, this is the right one — and the smaller circuit is genuinely cheaper on the electrical side.

The 4.5 kW covers 100 to 210 cubic feet and draws 18.8 amps. If you have a compact one or two person sauna, that's the better fit. This 6 kW is the middle of the range and the most common choice for a typical home sauna.

Same 6 kW output, same 25 amp draw, very different heaters. The Spirit offers genuine remote starting, twin safety sensors, and 110 lbs of stone for a much softer steam — at a considerably higher price and a shorter warranty. The KIP is the practical choice: simpler, cheaper, serviceable, and it does the fundamental job very well.

No. Match the heater to the room. Too much output means the heater reaches temperature and shuts off before the stones are properly charged, which gives you a hot room with weak steam — the opposite of what you want. It also means a bigger circuit and a bigger electrical bill.

Usually, if you're matching output. Going like-for-like off a working 6 kW is generally straightforward, but confirm your existing circuit is 240V on a 30-amp breaker first. Send us a photo of your old heater's rating plate and we'll tell you.

By parcel carrier. Freight is calculated to your address — ask us for a delivered price and you'll get one number.

Get in touch for current availability and a realistic date. We'd rather give you a real timeframe than a stock phrase.

Very little. Wipe the casing occasionally, check and restack the stones annually, keep debris from building up around the unit, and let the room air out after each session.

Call us. We handle warranty claims directly with Harvia rather than handing you a phone number, and Harvia's US parts network is deep — most issues are a part rather than a replacement.

Because the heater alone isn't the whole answer — this model needs a controller and stones to work, and freight varies by address. Request pricing and you'll get one delivered figure for the complete setup rather than a number you have to add to.

We're an authorized Harvia dealer, so you get the full manufacturer warranty and one point of contact from sizing through installation questions. We'll spec the heater against your actual room rather than a chart, confirm the right controller, and give you the electrical requirements before your electrician quotes.

Please review our return policy at thesaunarepublic.com/policies/refund-policy. Because heaters are sized to a specific room and hardwired on installation, talk to us before ordering if you have any questions — we'd much rather get the sizing right up front.
