Saunum Sauna Heaters

Saunum is an Estonian company whose heaters are built around a patented air blending system. It draws the hottest air from near the ceiling, mixes it with cooler, oxygen-rich air off the floor, and returns it low in the room. Saunum states this equalizes room temperature by more than 60 percent, in a room where the ceiling can pass 200°F while the floor sits under 100°F.

We carry the Air, the Air L and the Air Perfect, the wall-mounted AirSolo, the Auto Leil water dispensing unit, and the AirCube Double cabin with its own changing room. The closed-basket Air is the Saunum heater customers pick most often. Because a Saunum heats the bottom third of the room as well as the top, we size one a little larger than a standard sauna heater. Call (844) 565-1113 and we will run your numbers.

Saunum questions

What size Saunum heater does my sauna need?

Size by room volume, not floor area. The 4.95 kW Air 5 covers 106 to 212 cubic feet, the 6.9 kW Air Perfect 7 covers 210 to 350, the Air L 10 covers 283 to 494, and the 9.9 kW Air Perfect 10 reaches 565. Saunum’s manual says to take the larger heater when you land between two sizes.

Does a glass front change the size of heater I need?

Saunum’s manuals put a number on it. Add 3 cubic feet of volume for every square foot of glass, tile, brick, concrete or stone, and multiply the whole volume by 1.5 for uninsulated log, plank or stave walls. A 7 by 7 by 7 room is 343 cubic feet; a full glass front sizes it as 490, a 10 kW room.

What breaker does a Saunum heater need?

These run at 240 volts, single phase, and the US models are UL listed. The Air 5 draws 20.7 amps on a 30 amp breaker with #10 wire, the 6.9 kW Air 7 and Air Perfect 7 take a 40 amp breaker with #8, and the 9.9 kW Air Perfect 10 draws 41.25 amps on a 50 amp breaker with #6.

What comes in the box, and what do I order alongside it?

An Air arrives with its stone basket, the heat equalizing module, seven Himalayan salt spheres, the room and door sensors, the cables and a two year residential warranty. The AirIQ WiFi control and the stones are ordered separately: 110 pounds of stone for the Air 5, 120 for the Air Perfect 7, 180 for the Air L 10.
