A premium sauna heater that cycles air from the top of the sauna to the bottom for soft, even heat throughout the sauna.
The Saunum Air L solves the biggest problem with electric sauna heaters: your feet are cold while your head’s roasting.
This isn’t just marketing—Saunum’s patented air-blending system, developed in cooperation with Tallinn University of Technology, equalizes room temperature by more than 60% compared to traditional electric heaters. Traditional heaters create significant temperature stratification, with ceiling temperatures often exceeding 200°F while floor levels stay under 100°F—a difference of 80°F or more.
The Air L’s patented air-blending system fixes that by pulling hot air from the ceiling, mixing it with cool air from the floor, and redistributing it throughout your sauna.
Available in three power options (10kW, 13kW, 15kW) for rooms from 247 to 741 cubic feet. The Air L holds 265 pounds of stones—significantly more than standard heaters—for better heat retention and steam quality. UL-listed for North America. Made in Estonia.
The built-in fan mixes hot ceiling air with cool floor air to eliminate cold feet and create even, breathable heat throughout your sauna.
The Air L holds 265 pounds of stones—about 75% more than typical heaters—for better heat retention and longer-lasting steam.
Seven salt spheres positioned in the airstream release negative ions throughout your sauna for respiratory and skin benefits.
Control temperature, schedule sessions, and choose preset modes from your phone.
Built for daily use and intensive sessions with black steel construction tough enough for shared spaces, home gyms, and frequent sauna users.
The Saunum Air L comes with a 2-year warranty in residential saunas from the manufacturer and our local Minnesota support.
In the box:
This is more maintenance than basic heaters require. The annual electrical inspection and stone restacking aren’t optional—they’re required to keep the warranty valid and the heater operating safely.
