Product Overview
The Saunum Air L 15 is the highest-output model in the Air L range, designed for large residential sauna rooms. Along with 15 kW of heating power and a substantial stone capacity, it incorporates Saunum’s climate-equalizing air system to blend hot upper-level air with cooler lower-level air. The result is a more balanced temperature profile, comfortable heat at multiple bench levels and rich steam from the large stone mass.
Closed Basket and Open Basket versions allow the heater’s appearance and exposed stone surface to be tailored to the sauna design.
Why Saunum Is Different
Traditional saunas naturally develop strong temperature stratification: the hottest air rises while cooler air settles near the floor. Saunum’s integrated climate system is designed to circulate and blend those layers, producing a more even-feeling sauna environment while preserving the heat, stones and steam of a traditional sauna.
Key Features
- Integrated Saunum air-mixing technology helps balance temperature throughout the sauna
- Large stone capacity supports soft, generous steam when water is applied to the stones
- Adjustable airflow lets the sauna climate be tailored to personal preference
- Purpose-built electric sauna heater for residential indoor sauna installations
Recommended Sauna Size
459–741 cu. ft.. Correct heater sizing depends on total room volume and construction materials; glass, tile, masonry and other uninsulated surfaces can increase the effective sauna volume.
Required for Operation
Saunum AirIQ Wi-Fi control is required. Saunum specifies Air L for use with the AirIQ control system. Sauna stones are also required. Stone quantity varies by model/basket configuration.
