Harvia Spirit SP90E 9 kW Electric Sauna Heater Package

Get all the pieces you need to heat your sauna with the Harvia Spirit 9 kW Sauna Heater Package. This kit comes with the Harvia Spirit Heater, a Xenio or Fenix External Controller, and stones. Each piece is selected by our sauna experts, creating a convenient kit to simplify your shopping journey.

Harvia Spirit SP90E Heater

Turn your sauna into a celebration of nature’s beauty with the Harvia Spirit SP90E 9 kW Electric Sauna Heater. The Spirit’s cage design showcases all 110 lbs. of stone, welcoming water-pouring for gentle, soothing steam.

While this design naturally optimizes airflow, it’s paired with an integrated ventilation system to create even temperatures in saunas ranging from 177 - 494 ft3 (adj.). Better yet, these vents help cool the back of the heater for safe mounting directly on wooden walls.

This heater's external controller gives you the freedom to adjust your sauna's temperature up to 194℉ to dial in perfect sessions every time.

Harvia Spirit Controller

The Harvia Spirit uses an external controller that lets you dial-in the perfect sauna environment. There are two options available with this package: the Xenio CX45 and the Fenix FX45.

  • Xenio CX45: Touchscreen controller that gives you the power to adjust your sauna and schedule sessions through the MyHarvia App.
  • Fenix FX45: Touchscreen controller with integrated AI that adapts to deliver the perfect sauna experience. Includes 3 customizable heating profiles and allows for scheduling and adjustment through the MyHarvia App.

These controllers can be linked to the sauna’s lighting, ventilation, fans, and timers, offering an all-in-one sauna control destination. Both the Xenio and Fenix are compatible with the MyHarvia App, giving you the power to adjust and operate your sauna right from your smartphone.
