Time-Tested Reliability
Harvia is one of the most trusted, reliable brands for personal and commercial sauna heaters. With serviceable heating elements and high-quality Finnish engineering, Harvia has proven itself time and time again.
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.
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.
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.
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.
