Narvi NC Electric Flow (Wi-Fi) 6 kW & 9 kW Electric Sauna Heaters

Narvi NC Electric Flow (Wi-Fi) 6 kW & 9 kW Electric Sauna Heaters

Simplistic and minimalistically elegant Narvi NC Electric Flow heaters combine everything you want from a traditional wall-mounted sauna heater but with a modern twist: a decent stone capacity of 55 lbs that heats quickly, soft or sharp löyly (steam) production, and digital control.

In addition to the popular black, these heaters are also available in stylish white.

Requiring the most minimal side and rear clearances to combustibles, NC Electric is a great fit for tighter spaces.

Whichever Narvi NC Electric 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.

The controller can be installed inside or outside the sauna room, but not outdoors in freezing temperatures. Narvi Flow control unit 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). Using this function means your sauna will have the desired temperature when you get home after a long day.

The Wi-Fi models always include a door switch for safe operation.

Like Narvi’s all heaters in the Flow series, NC Electric models are handcrafted in Lapinkylä, Finland.
