Question 1

What size Saunum heater does my sauna need?

Accepted Answer

Size by adjusted room volume, not floor area. Multiply the inside width, depth and height in feet. Add 3 cubic feet for every square foot of glass, tile, brick, concrete or stone, and multiply by 1.5 if the walls are logs, planks or staves without insulation. Then pick the heater rated for that number. If you land where two sizes overlap, Saunum’s manual says to take the larger one. The manual’s own example: a 7 × 6 × 8.4 ft room is 353 cu ft, and a 24 sq ft glass door adds 72, so it needs a heater rated for at least 425 cu ft.

Question 2

Air, Air Perfect or Air L: what is the difference?

Accepted Answer

All three blend the air the same way. The Air (5 or 7 kW, up to 318 cu ft) is the compact one, with a chimney to the ceiling that pulls the hot layer down. The Air Perfect (7 or 10 kW, 210 to 565 cu ft) stacks two stone baskets, needs no chimney and only about 3 inches of clearance, so it suits corners and tight rooms. The Air L (10, 13 or 15 kW, 283 to 812 cu ft) is the commercial-grade one, with 180 to 190 pounds of stone, for big rooms and saunas that run all day.

Question 3

What does the price include?

Accepted Answer

Every Air, Air L and Air Perfect runs only with Saunum’s AirIQ Wi-Fi control, and each needs a load of stones. Here the Air and Air Perfect are priced as packages with both included. The Air L is priced as the heater, and you add the AirIQ and stones when you order; the heater cards above show the complete price. You also need a dedicated 240V circuit and a licensed electrician. Optional: a safety rail, the fan button, the AutoLeil, and salt or aroma kits.

Question 4

What breaker does a Saunum heater need?

Accepted Answer

Every current US model runs on 240V single phase. From Saunum’s manuals: Air 5, 30 A breaker with #10 wire. Air 7 and Air Perfect 7, 40 A with #8. Air Perfect 10 and Air L 10, 50 A with #6. Air L 13, 70 A with #6. Air L 15, 80 A with #4. Saunum says not to connect the heater through a GFCI breaker.

Question 5

Will a Saunum fit under my ceiling?

Accepted Answer

The Air and Air L run a telescopic chimney from the heater up to the ceiling, and Saunum’s manual draws it for ceilings from 73 to 95 inches. The Air Perfect has no chimney and needs at least 77 inches. A 7-foot ceiling (84 inches) fits every model. Put your ceiling height in the finder above and it checks this for you. Taller than 95 inches? Call us before you order an Air or Air L.

Question 6

How hot does a Saunum get?

Accepted Answer

Saunum rates every model for a sauna at 140 to 194°F, and the manual says not to run it hotter. What the fan changes is where that heat ends up. With the fan off, it heats like any electric sauna, hottest at the ceiling. With the fan on, the ceiling heat comes down to the benches, and the steam from water you pour on the stones spreads through the room instead of rising straight to the ceiling.

Question 7

Can I keep the heater I already have?

Accepted Answer

Yes, with the AirSolo. It is not a heater: it is Saunum’s separate climate unit, and it adds the air blending to the electric heater you already have. It runs on 120V, which makes it the usual answer for a finished room with cold feet.

Question 8

Does the fan make the sauna feel less hot?

Accepted Answer

It moves the heat to where you sit. Run the fan off while the room preheats, then choose one of three fan speeds. Owners describe a heat that feels less harsh while the body still gets very hot, and with the fan off you have a classic, hard-hitting electric sauna.

Question 9

Is the fan loud?

Accepted Answer

You will hear it. Every fan makes some sound, and Saunum’s manual says so. You pick one of three speeds on the AirIQ or leave the fan off, and the optional fan button turns your preset fan mode on or off from the bench.

Question 10

How do I vent a sauna with a Saunum?

Accepted Answer

Saunum’s manual makes both vents mandatory. The fresh-air intake goes under or next to the heater, no higher than 12 inches off the floor, in a pipe about 4 inches across. The exhaust goes as far from the heater as you can put it, higher than the intake at 24 to 47 inches off the floor, in a pipe about twice as wide (6 to 8 inches). An exhaust lower than the intake is the layout the manual tells you to avoid.

Question 11

What warranty comes with a Saunum?

Accepted Answer

Saunum warrants each heater for two years in a home sauna, against defects in materials and assembly. A claim needs two things: a qualified electrician connected the heater, and you have the completed installation report, so fill it in on install day and keep it. The heating elements, the salt spheres and labor are not covered. If anything comes up, we work it out with Saunum for you.

Question 12

Which saunas take a Saunum?

Accepted Answer

Any well-built electric sauna in its rated size range, with a ceiling the heater fits under. Some makers list it for you: Auroom’s own heater chart names the Saunum Air for most of its indoor rooms and the Mira S, and the Air Perfect or Air L for its bigger rooms and outdoor saunas. See every Auroom sauna with the heaters Auroom approves for each. The SaunaLife G6 above is Saunum’s own Classic sauna.

Question 13

Saunum, HUUM or Harvia: which should I buy?

Accepted Answer

We sell all three, so it comes down to how you like to sauna. HUUM and Harvia build traditional heaters: the heat rises, the top bench is the hot seat, and plenty of people want exactly that. A Saunum builds a fan and air channels into the heater that pull the ceiling heat back down, so the lower bench counts and the heat feels less harsh. If that is what you or the people you sauna with want, it’s a Saunum. If you want the classic top-bench hit, a HUUM or Harvia is the straightforward choice, and we can size either one for your room.
