to a friend
The Air L 13 has plenty of power for my big six-person sauna and the Saunum airflow keeps the heat perfectly even across all the benches. No cold corners at all. The stainless build is heavy duty and looks premium. Heats up faster than I expected for the size. Definitely needs professional 240v wiring given the kilowatts.
For a large sauna the Air L 13 is excellent. The airflow system distributes warmth so the upper and lower benches feel the same, which is rare in a big space. Stainless steel finish is beautiful and the steam is great. An electrician handled the heavy-duty wiring.
I have a large traditional sauna and needed serious power. The Air L 13 delivers, heating the whole cabin evenly and quickly. The Saunum airflow really does eliminate the hot-head cold-feet effect. Built like a tank in stainless. Professional wiring is a must but the result is fantastic.
The Air L 13 performs beautifully in our large sauna with truly even heat. Four stars because the high power means a more involved electrical install and a bigger breaker, so plan for an electrician. Once running it's superb, even warmth and excellent steam. Stainless build is gorgeous.
Heats our spacious family sauna fast and evenly. The Saunum airflow and stainless construction are top notch. Steam is excellent. Highly recommend for bigger cabins.
