Harvia Spirit SP90E 9kW Complete Heater Package with Fenix WiFi Control & Stones

Harvia Spirit SP90E Complete Heater Package
Bring refined Finnish sauna design home with this 9 kW electric sauna heater package, pairing the Harvia Spirit SP90E with Fenix FX45 WiFi control and four boxes of rounded Harvia sauna stones. Designed for residential sauna rooms from 177 to 494 cubic feet.

Made in Finland, the Spirit combines a softly curved black exterior with the natural texture of exposed stones. Its wall mounted design creates an understated focal point, while the Fenix glass touchscreen provides intuitive control of temperature and operating time, with MyHarvia smartphone control and monitoring.

Supplied as components for a 240 V, single phase installation. Professional hardwiring, wall mounting, stone placement and the required protective heater fence must be arranged before use. Final heater selection should account for sauna volume, glazing, insulation and installation requirements.
