Length times width times height in feet gives the base figure. Uninsulated log, plank or stave walls multiply it by 1.5.

Saunum's current US AirIQ manual (August 2026, as in 2025) rates the power unit for heaters up to 15.2 kW, and the Air L 13 is 12,900 W. An earlier 2023 edition of that manual capped it at 12 kW and called for a contactor box above that, so we confirm which edition ships with your order, and your electrician follows the manual in the box.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\n    \u003cdetails\u003e\u003csummary\u003eCan the Saunum Air L 13 go in a gym, club or rental sauna?\u003c\/summary\u003e\u003cdiv class=\"snairl13-fb\"\u003e\n      \u003cp\u003eThe manual that ships with the Air L 13 covers private saunas for two years and gives no commercial term, so ask us before buying for a gym, club or rental, and we will ask Saunum's US support for you.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\n    \u003cdetails\u003e\u003csummary\u003eShould I pick the Saunum Air L 13 or the Air L 10 for a room around 450 cubic feet?\u003c\/summary\u003e\u003cdiv class=\"snairl13-fb\"\u003e\n      \u003cp\u003eBoth are rated for 424 to 494 cubic feet, and Saunum's manual says to take the larger heater when a room falls between two sizes: the Air L 13.

No door sensor comes in the Air L carton, so before shipping we confirm with you whether your setup needs one for remote start. Once a scheduled session reaches temperature it runs half an hour, then ends unless confirmed. Wi-Fi is optional: choose \"Set up offline\" at the Wi-Fi step (older panels say \"Skip\"), and the heater runs from the panel without the app.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\n    \u003cdetails\u003e\u003csummary\u003eCan the Saunum Air L 13 go on a GFCI breaker?\u003c\/summary\u003e\u003cdiv class=\"snairl13-fb\"\u003e\n      \u003cp\u003eNo. A GFCI breaker is ruled out in Saunum's manual.
