Harvia Spirit SP90FC 9 kW WiFi Electric Sauna Heater (built-in control)

The Harvia Spirit SP90FC WiFi— the 9 kW version of Harvia's Spirit WiFi range. Same wall-mounted design, same built-in MyHarvia WiFi control, but with the heat output to handle mid-sized residential saunas from 8 to 14 m³.

All-in-one solution: no separate contactor box, no separate control panel to run cables to. Wall-mount, wire in, connect to the MyHarvia app, and start it from your phone before you leave work.
