Description
The Harvia Spirit SP90 is a 9kW wall-mounted electric sauna heater for home saunas of 280 to 494 cubic feet, with a curved open frame that shows off 110 lbs of round stones. Air channels in the frame help spread heat evenly and cool the wall behind it, and a safety device on top prevents start-up if something is placed on the heater. It runs from a separate Harvia control, such as a Xenio or Fenix WiFi control, sold separately.
