Description
The Narvi 30 and 50 wood burning sauna heaters are an excellent choice for larger saunas and commercial wood burning saunas. The models’ large capacities do not allow size to compromise on the quality of the löyly. These high capacity sauna heaters maintain the brand standard of low emissions. The large door aperture ensures easy placement of fuel wood, a must when dealing with stoves of this size. The sauna experience is enhanced by the combination of the stylish black painted steel casing and cast iron glazed door that one can admire the flames through. For when relaxation is paramount, the fueling can be done from outside your sauna. This is because the Narvi 30 and Narvi 50 are available as tunnel models.
- The glazed hatch ensures an even flame distribution within the heater whilst also creating a pleasing cosy atmosphere. The wooden handles and cast iron latch twin perfectly, both comfort and durability, and are vital for ensuring personal safety and pleasantly cool handling during use.
- Narvi heaters are market leaders in emissions and health & safety standards. A point of paramount importance when it comes to the ideal relaxation experience.
- As with all Narvi heaters, 10mm thick steel is used for the firebox, extending time between servicing, a choice that that is borne out of their 'quality-first' ethos. This choice to use thicker, better quality steel than their competitors is one of Narvi's key distinguishing features.
*Please note that a suitable flue kit and sauna stones are to be purchased separately. Browse our sauna flue kits and chimney parts.*
This heater requires up to 65-100kg of sauna stones. We recommend using 10-15cm Olivine Diabase or Vulcanite Sauna Stones for optimal performance.

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 builder/plumber/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.
