Harvia Spirit 9 kW Electric Sauna Heater

The Harvia Spirit 9 kW is a premium wall-mounted electric sauna heater designed for sauna rooms between 177 and 494 ft³ (5–14 m³). With its elegantly curved design and open stone structure, the Spirit blends modern aesthetics with natural sauna tradition, especially when paired with round sauna stones for a smooth, balanced look.

Engineered for exceptional heating performance and safety, the Spirit quickly and evenly warms the sauna while integrating advanced protective features. A built-in safety sensor prevents the heater from activating if items are placed on top—ideal for safe remote startup. Two additional sensors continuously monitor both heater and room temperatures to prevent overheating.

The Spirit’s 110 lb (50 kg) stone capacity delivers soft, consistent heat and rich steam. Its symmetrical design enables flexible installation on either side of your sauna, ensuring a clean, balanced appearance.

The Harvia Spirit 9 kW is Wi-Fi compatible and requires the Harvia Xenio CX45-U1-U3-XW digital control unit (sold separately) for operation. The splash-proof control panel can be installed inside or outside the sauna and supports remote control via the MyHarvia mobile app for maximum convenience.

Note: Control unit and sauna stones sold separately.
To operate this heater, you must purchase the Harvia Xenio CX45-U1-U3-XW controller.
