The Harvia Spirit SP90FC WiFi has been engineered for sauna enthusiasts seeking a powerful heating solution without compromising on design. Featuring Harvia’s distinctive curved silhouette, this premium electric sauna heater becomes a focal point within the sauna while delivering outstanding thermal performance and user comfort.
Designed for home sauna rooms between 8 and 14 cubic metres, the 9.0 kW Spirit quickly reaches operating temperature thanks to integrated airflow channels that improve heat circulation throughout the cabin. The innovative structure exposes more of the sauna stones to the air, creating gentle, moisture-rich steam and a more enjoyable sauna climate.
Unlike traditional sauna heaters, the Spirit SP90FC incorporates a built-in safety system that supports remote operation without requiring additional safety devices. The included Harvia Fenix WiFi control panel utilizes intelligent learning technology to understand your sauna’s heating characteristics, helping you accurately predict when your sauna is ready for use. Remote management is available through the MyHarvia platform, allowing convenient scheduling and monitoring directly from your smartphone.
