to a friend
The Air L 15 in black looks sleek and handles our big six-person sauna with ease. The signature air-distribution tech keeps the heat even from bench to bench, which in a large space really matters. 15kW heats the whole room fast. The black finish is a beautiful modern touch. Have an electrician do the install.
Our larger sauna used to have hot and cold zones, but the Air L 15 fixed that completely. The climate equalization makes every seat comfortable. It heats quickly for its size and the black housing looks premium. Excellent heater.
A 15kW heater is serious power and needs proper three-phase wiring in many cases, so factor in an electrician. Performance is excellent - fast, even heat across our large sauna - and the black finish is gorgeous. Four stars only for the install complexity.
The black finish makes it look like a designer piece, and the air-flow technology delivers truly even warmth in our spacious sauna. Heats fast and runs smoothly. Couldn't be happier.
We have an oversized home sauna and this is the first heater that heats it evenly and quickly. The Saunum air distribution is the difference maker. The matte black look is stunning. Worth every dollar.
