Narvi Saana Flow (Wi-Fi) 6.8 kW & 9 kW Electric Sauna Heaters

Narvi Saana Flow (Wi-Fi) 6.8 kW & 9 kW Electric Sauna Heaters

Narvi Saana pillar heater lets sauna stones steal the show through its Saana-shaped steel grid design (Saana is a famous fell in Enontekiö, Finland). With a stone capacity of 176 lbs, the heater stores heat efficiently and offers long-lasting and enjoyable löyly (steam).

Whichever Narvi Saana variant you choose, it comes with an external Narvi Flow control unit (four options include Wi-Fi for remote control). The controller allows you to start the heater, adjust the sauna room temperature (105–240 F), and schedule the heating start time and duration.

You can install the control unit inside or outside the sauna room, but not outdoors in freezing temperatures. The controller is low voltage and is protected against splashing water (IPX5).

With the Wi-Fi options, you can control the heater remotely together with the free Narvi Flow app (found on the App Store and Google Play). This functionality is most ideal when you want your sauna hot and ready the minute you arrive home.

The WiFi models always include a door switch for safe operation.

All Narvi Saana heaters are handcrafted in Lapinkylä, Finland.
