Harvia Spirit SP90E 9 kW Sauna Heater With Digital Control Compatibility

Product Description

The Harvia Spirit SP90E (HSPE90U1M) is a 9 kW Finnish‑made electric sauna heater designed with a curved, organic profile that highlights its rounded sauna stones. Engineered for fast, even heating, the Spirit Series combines modern aesthetics with advanced safety and digital functionality.

Unique air‑ventilation channels help maintain consistent sauna temperatures by improving airflow around the heating elements and cooling nearby wall structures. Dual safety sensors monitor both the heater and the sauna room temperature, preventing overheating and ensuring safe operation. The heater cannot be activated if objects are placed on top, supporting remote start functionality when paired with a compatible Wi‑Fi control system.

The Spirit Series works with Harvia Xenio Wi‑Fi controls and the MyHarvia mobile app (sold separately), enabling digital control of temperature, lighting, and ventilation.
