Description
The Narvi NC is one of our most popular domestic electric sauna heaters, a wall-mounted, Finnish-made design whose 25 kg stone capacity creates an impressively soft löyly for a heater of this size. It is available at 6 kW for saunas of 6–9 m³ or 9 kW for 9–15 m³, in white, black or stainless steel to suit the look of your sauna. The standard version includes an integrated power supply with a digital control unit on 3 metres of cable, which can be mounted inside or outside the sauna; the E-model is supplied without a controller for pairing with a separate control system. Narvi’s 8.5 mm heating elements warm the room quickly and offer a long service life, the 6 kW model connects to single-phase or three-phase supplies while the 9 kW requires three-phase, and sauna stones are purchased separately.

Installation
Installation and maintenance must be carried out by a certified electrician, with the electricity supply isolated at the fuse panel before any work begins. Under IEC 60364-7-703 and BS 7671:2018 an electric sauna heater does not have to be connected through an RCD, and for reliable operation the manufacturer recommends that the heater supply is not run through one; other electrical devices in the sauna room should be RCD protected. A local point of isolation covering all live conductors is recommended. The installation manual in the Downloads tab and local wiring regulations must be followed. The temperature sensor is wall-mounted above the heater, 100 mm below the ceiling, as set out in the manual.
Sauna stones
This heater requires up to 25 kg of sauna stones, purchased separately. We recommend 5–10 cm olivine diabase or vulcanite stones for the best performance.
