The Narvi NC Electric is one of our most popular electric sauna heaters. Its elegance and class set this quality heater apart from its competitors. The large stone capacity creates an impressive löyly for a heater of this size.
Note: Sauna stones to be purchased separately
This heater requires up to 25kg of sauna stones. We recommend using 5-10cm Olivine Diabase or Vulcanite Sauna Stones for optimal performance.
The NC electric comes with a digital control unit that can be installed inside or outside the sauna for accurate temperature and timing adjustments. The control unit comes with 3 metres of cable.
The stylish design of the NC Electric is complemented by a range of colour options, including white, black and stainless steel, making choosing a heater to suit the aesthetic of your sauna an easy task. The 8.5 mm diameter heating coils warm the sauna very quickly and have an exceedingly long lifespan and low risk of overheating. The heater comes in 6 kW and 9 kW options depending on the size of your sauna.
This heater must be installed by a qualified electrician and can be easily installed on both single phase 240v and three phase 400v power supplies

Product Disclaimers
All Narvi sauna heaters are CE tested and bear the Finnish Key Flag Symbol. This is awarded to sauna heaters that are made and designed in Finland, where over 95% or more of the production must be within Finland itself. There are many brands that claim to be made in Finland but are actually made in the Far East or Russia and merely assembled or labeled in Finland. Watch out for these symbols as a mark of an authentic, Finnish-made, safe, quality product:

As part of Finnmark Sauna's Endurance Ethos, we only deal in products that are market leaders in quality. We commit ourselves to search exhaustively for the highest quality authentic Finnish sauna products.
Please note, we recommend that sauna heaters should be installed by a suitably qualified electrician/builder/fitter. Finnmark Limited accepts no liability for loss or injury caused by the incorrect installation or misuse of your sauna heater. Please Contact Us if you require information on our recommended fitters.
