Overview
The Harvia Spirit Electric Sauna Heater is a premium Finnish-made sauna heater with a curved, organic aesthetic and open-air rounded stone configuration. Available in 6kW (up to 294 cu. ft.), 8kW (up to 431 cu. ft.), and 9kW (up to 494 cu. ft.) with a choice of Xenio or Fenix WiFi control panel. Rocks are included. Dual safety sensors prevent overheating and block remote activation if items are placed on the heater, making it safe to start via the WiFi app.
Key Features
- Curved Organic Design: Distinctive rounded aesthetic with open-air stone placement — one of the most visually distinctive heaters in the Harvia lineup
- Dual Safety Sensors: One monitors the heater itself; one monitors sauna room temperature — prevents overheating and blocks remote start if items are on the heater
- WiFi Control Included: Choose Xenio (touch panel, WiFi, controls temperature/lighting/fan/time) or Fenix (4.3" AI-adaptive glass touch screen, MyHarvia app compatible)
- Rocks Included: Minimum 110 lbs of Harvia R-991 stones included — no separate purchase required
- Fast Heat-Up: Reaches target temperature quickly for efficient pre-session warm-up
- Finnish Made: Designed, engineered, and manufactured in Finland
Why This Product Stands Out
The Spirit’s dual safety sensor system is a meaningful differentiator — most electric sauna heaters have a single thermal cutoff. The second sensor monitoring the room temperature adds an additional layer of protection, particularly important when using remote WiFi start. The curved stone configuration also holds more stones in an open-air arrangement than flat-panel heaters, producing more steam when water is ladled over the rocks.

Who This Is For
A strong choice for sauna owners who want a visually distinctive heater with WiFi remote start and a robust safety system. The dual sensor design makes it particularly well-suited for those who want to pre-heat their sauna remotely before arriving. The three size options (6–9kW) cover small to large sauna rooms up to 494 cu. ft., making it versatile across a range of home sauna installations.
