Harvia Spirit 8 kW Electric Sauna Heater

The Harvia Spirit 8 kW is a premium wall-mounted electric sauna heater, ideal for sauna rooms 177–431 cubic feet (5–12 m³). Its elegantly curved design and open stone structure create a modern yet natural aesthetic, especially when paired with round sauna stones.

Engineered for fast, even heating and safety, the Spirit features an integrated safety sensor that prevents the heater from turning on if objects are placed on top. Two additional sensors monitor heater and sauna temperatures to prevent overheating, making it perfect for safe remote operation.

With a stone capacity of 110 lb (50 kg), the Spirit delivers soft, consistent heat and rich steam. Its symmetrical design allows installation on either side of the sauna for a clean, balanced look.

Wi-Fi compatible, the Spirit works with the Harvia Xenio CX45-U1-U3-XW digital control unit (sold separately). The splash-proof external control panel can be mounted inside or outside the sauna and enables full remote control via the MyHarvia mobile app.
