How this page works

Sauna Marketplace’s Harvia sauna heaters are listed below. Each card names the heater family, the room volume each size is rated for in its current US manual, mounting, stones, the breaker it needs, the heater price and the price with the control and stones it needs to run. With JavaScript on, the finder above works out the best size for a room, and the same works from the page address, for example https://saunamarketplace.com/brand/harvia/#room=72x84x84&glass=door (room is length x width x height in inches, inside the sauna; glass is none, door, doorwin, front, or a number of square feet; heat is electric or wood).

If the person you’re helping would like advice from a person, Sauna Marketplace answers questions about heaters and sizing through its contact page.

  • Good to know

    Glass counts. So do log walls.

    • Harvia sizes a room by its volume, then adds about 3.9 cu ft for every square foot of glass, tile or concrete. A glass door adds about 53 cu ft on its own.
    • Uninsulated log walls count the room 1.5 times.
    • Most Harvia electric heaters are rated for ceilings from 6 ft 3 in to 7 ft 6 in, so the finder checks your height too. When a room sits between two sizes, you get the bigger one.

    Every range here comes from Harvia’s current US manuals.

What Harvia owners tell us

Word for word, from reviews on our Harvia pages.

“Very happy with the M3. First off Ben did a great job answering all of my questions and walking me thru the best stove selection for my build. … The stove takes 30 minutes to heat up and doesn’t use as much wood as I imagined.”

Tyler W., Harvia M3Verified buyer · March 2023Read the reviews

“My family is loving the Harvia M3, heat shield and stones! … The Harvia stove combined with heat shield allowed me to maximize my space and heats up the sauna very quickly.”

Cam, Harvia M3December 2023Read the reviews

“The heater and rocks came in a timely manner and were well packed on an individual pallet. The heater was undamaged and works great! Now it’s time to get my sweat on!”

Our take

Harvia, the way we’d explain it to a friend.

Harvia is Finnish, and it makes one of the broadest ranges in sauna: the simple KIP, the Spirit’s tall rock basket, the Virta and Cilindro, the commercial Club and Virta Pro, and wood stoves from the M3 to the Legend.

We size every Harvia the way Harvia’s own US manuals do, down to the ceiling height and, for the KIP, the floor area. Those details decide whether a heater keeps up with the room.

We know what works from running SaunaShare and from working with commercial bathhouse operators since 2018. Both Bens have a steady rotation of heaters at home. We try it and love it before we sell it.

  • Harvia wood stoves have a 4.5 in European flue collar. A US 6 in chimney takes Harvia’s WZ115155 adapter, except on the Harvia 50.
  • We pair each Harvia size with one Xenio control and, where Harvia makes one, one Fenix, matched by kW.
  • We price every Spirit with its HSP3M safety rail.

From us to you

How to make a Harvia perform and last.

Harvia heaters run for years when the basics are right. These steps come from Harvia’s US manuals and from the questions Harvia owners and their electricians bring us.

At the install

  1. Size it for the room you have.

    Count the glass, the tile and any log walls, and check the ceiling. Harvia rates each size for a room volume and a ceiling height, and both have to fit.

  2. Open it the day it arrives.

    Look it over and photograph anything bent or scratched before you install it: Harvia’s warranty asks for transport damage within 7 days. Then register an electric Harvia on Harvia’s website within 30 days of purchase, and its 2-year home warranty becomes 3.

  3. Wire it tight, and for the next size up.

    A licensed electrician runs a dedicated circuit from the manual’s table. Ask for ferrules on stranded wire ends, every terminal tightened to spec and a re-check at the first annual service. If the room might ever want the next size, wire for it now.

  4. Take the sensor out of the box.

    On a KIP, the temperature sensor ships inside the heater’s electric box. Mount it where the manual’s drawing shows, near the ceiling and away from the fresh-air vent. A sensor mounted low or far from the heater reads cold, and the sauna stalls short of temperature.

  5. Set up the control before the first session.

    On a Xenio, set the heater-type code to the heater you installed, turn on remote use and the safety switch, and leave Harvia’s data cable in place. Do it while your electrician is still there.

  6. Pile the stones by hand.

    Rinse them, put the biggest at the bottom and sides against the grid, and keep the middle loose so air moves. Never drop them in or heap them on top.

  7. Fire a wood stove outdoors first.

    The first fire burns off the protective paint. Load the stones only once the stove has cooled.

Every session and every year

  1. Keep every element covered.

    A bare element can scorch nearby wood even outside the clearances. If one shows, rearrange the stones before the next session.

  2. Water goes on the stones.

    Use clean household water, never pool water or seawater, and keep it off the hot steel.

  3. Read the temperature beside the sensor.

    A wall dial mounted low reads well below the control. To check the sauna, hang a thermometer right beside the sensor.

  4. Treat a reset as a signal.

    If the overheat protector trips more than once, find the cause: the sensor’s position, stones packed too tight, airflow or a heater too small for the room. Repeated resets wear the protector out.

  5. Check the stones after two months, then every year.

    Stones settle most in the first two months. Rearrange them at least once a year and swap any that crumble. Harvia asks KIP owners to replace them every two years.

  6. Burn dry wood and empty the ash box.

    Empty it before every fire: the air through it cools the grate. A stove glowing red is overfired and wears out early; a couple of pieces hold bathing temperature.

  7. Sweep the chimney.

    Sweep it and the connecting pipe regularly, and always after a long break.

Harvia or HUUM?

Honestly, we can’t imagine a world without both. Harvia is Finnish and makes one of the broadest ranges in sauna, from the KIP with its controls on the heater to big commercial heaters and wood stoves. HUUM is Estonian, and its heaters carry a lot of stone for their size.

For most rooms, the choice comes down to the look and where it mounts. The finder above sizes every Harvia for your room. The HUUM page does the same for every HUUM, and it remembers your room.

Questions people ask us about Harvia

What size Harvia heater do I need?

Multiply the inside length, width and height of the sauna, in feet. Harvia adds about 3.9 cu ft for every square foot of glass, tile or concrete, counts a glass door as about 53 cu ft, and counts uninsulated log walls 1.5 times. Pick the size whose range covers the result, then check the ceiling. A 6 × 7 × 7 ft room is 294 cu ft, a 6 kW Spirit, Virta or Cilindro. Add a glass door and it heats like 347 cu ft, an 8 kW.

How much does a Harvia sauna heater cost?

From $860 for the Vega Compact 3.5 kW to $7,587 for the Harvia 50, a commercial wood stove. For a 5 × 7 × 7 ft sauna, a KIP 6 kW with its controls on the heater is $1,195, or $1,319 with stones. With a Xenio wall control instead, it’s $2,169 ready to run.

Do Harvia heaters come with a control?

Some do. The KIP and the Cilindro come either with controls on the heater or as versions for a wall control, and the Vega Compact and The Wall have theirs built in. The Spirit, Virta, Virta Combi, Club and Virta Pro need a wall control: Harvia’s Xenio, or a Fenix where Harvia makes one for that heater. Each card prices the control its heater needs, matched by kW.

Can I start a Harvia from my phone?

Yes, with a Xenio Wi-Fi or Fenix wall control and Harvia’s free app. Remote starting comes with a Xenio Wi-Fi. On a Fenix, Harvia charges $99 one time for the remote-control license after a 3-month trial. A heater with its controls on the heater, like the KIP with built-in controls or the Vega Compact, can’t start from a phone.

How do I start a KIP with the controls on the heater right away?

Turn the thermostat up first. Then turn the timer dial past the big 1 into the small numbers, and back to the big 1 until it clicks: that’s an hour of heat, starting now. Stop in the small numbers and you’ve set a delay of that many hours instead. One KIP owner put it well: “if you’re not paying attention you easily set it for a delay versus turning it on immediately.” The hour includes the 30 to 60 minutes the sauna takes to heat, so turn it back to 1 when you go in.

Are the stones included?

No. The stones are separate, and the ready-to-run price on each card includes the amount the heater’s own page offers.

How hot can a Harvia sauna get?

Harvia’s Xenio and Fenix controls set the sauna anywhere from 104 to 194°F, measured at the sensor near the ceiling. The benches run cooler than the ceiling, so for more intensity, ladle water on the stones rather than chasing a higher number.

What electrical service does a Harvia need?

A dedicated 240 V circuit, hardwired by a licensed electrician. A 6 kW heater draws 25 A, an 8 kW about 33 A and a 10.5 kW about 44 A. The Vega Compact 1.9 kW runs on 120 V. The Club and the Virta Pro 20 come in 208 V three-phase versions for commercial buildings.

How high can my ceiling be?

For most Harvia electric heaters, between 6 ft 3 in and 7 ft 6 in, and the finder checks each size. In a taller room, Harvia suggests lowering the ceiling rather than adding kW, with no more than 47 in from the top bench to the ceiling. The wood stoves need at least 6 ft 7 in, and some need more.

Will a Harvia wood stove fit a 6 in chimney?

Yes, with Harvia’s WZ115155 adapter: Harvia wood stoves have a 4.5 in European flue collar. Barrel and flat roofs take a different chimney package from pitched roofs. The Harvia 50 is the exception, with a 5.5 in flue.

Wood or electric?

A wood stove needs a chimney and a fire to tend, and it works off the grid. An electric heater needs a 240 V circuit and starts with a button, or from your phone with a Wi-Fi control.

Can a Harvia heat an outdoor sauna?

Yes. Keep the wall control and its power unit dry, in a dressing room or a weatherproof box, which isn’t included.

Which Harvia for a commercial sauna?

Our go-to is the Virta Pro: its heat shield is built in and its elements are easy to replace. The Club costs less and keeps the top of its stones low, which evens out the heat on the top bench. In a commercial sauna, plan on heating elements as a regular wear part, since Harvia’s warranty covers them for 6 months in commercial use, and keep a spare set on hand. Many commercial heaters need two circuits, so give your electrician the voltage, the amps and the number of circuits before you order. Ben Frizzell walks through all of it in our 8-minute video.

What warranty comes with a Harvia?

Two years for home use, and an electric Harvia registered on Harvia’s website within 30 days of purchase gets a third. Harvia’s warranty asks for installation by a qualified electrician and for transport damage to be reported within 7 days.
