The generous stone capacity means more thermal mass, which translates to softer, more consistent heat and better löyly (steam) when you pour water on the stones. The cylindrical design allows efficient air circulation around the heating elements and stones.
This heater includes Wi-Fi connectivity for smartphone control, plus an external wall-mounted controller with a digital LCD display. Control your sauna from anywhere using the free app, or adjust settings at the controller outside your sauna door.
The Wi-Fi system includes a compact wireless adapter that connects to your home network. Setup takes just minutes, and the app works with both iOS and Android devices.
