The Narvi 30 & Narvi 50 Through-the-Wall wood-burning sauna heaters embody the pinnacle of Finnish durability and performance. Designed to be fuelled from outside the sauna room, they are the ideal choice for sauna owners who are seeking for a pristine and uncluttered interior. 

Engineered for larger, commercial sauna spaces and groups of bathers, these robust heaters deliver generous, consistent heat and luxuriously soft steam - the hallmark of an authentic Finnish sauna. The painted steel outer housing lends a sleek, understated elegance while offering long-lasting resistance to wear. 

The design places the chimney connection conveniently on top of the heater, optimising installation flexibility. Built with the signature strength and craftsmanship or Narvi, the 30 and 50 models provide the capacity and resilience required for professional facilities. 

For those seeking exceptional heat output, enduring quality, and minimalist Nordic design, the Narvi 30 and 50 Through-the-Wall heater are the ultimate solution for expansive sauna environments. 

  • Narvi 50 Tunnel supplied with Stove Chimney Adapter part no. 6180

*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.

The warranty on this wood burning sauna heater is 1 year.

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.

Please note, we recommend that sauna heaters should be installed by a suitably qualified builder/plumber/fitter.
