Harvia Spirit SP90E 9 kW 240V/1Ph Electric Sauna Heater

Turn your sauna into a celebration of nature’s beauty with the Harvia Spirit SP90E 9 kW 240V/1Ph 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 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 (not included) gives you the freedom to adjust your sauna's temperature up to 194℉ to dial in perfect sessions every time. 

The Harvia Spirit SP90E Electric Sauna Heater requires a Harvia Xenio CX45 or Fenix FX45 Controller and Harvia Spirit Sauna Stones for operation. 

What’s Included

1x Harvia Spirit SP90E 9 kW Sauna Heater

1x Wall Mounting Bracket Kit and Hardware

1x Harvia Spirit SP90E Installation and Operation Manual

ATTENTION: The Harvia Spirit SP90E Sauna Heater does NOT include stones or a controller. These elements are required for operation. Browse Harvia Sauna Stones and Harvia Xenio CX45 or Fenix FX45 Controllers under Suitable Accessories at the top of this page to complete your setup.
