Narvi Black 20 Wood Burning Sauna Heater (B-Stock)
Narvi Black 20 wood burning sauna heater is an excellent, well-built, affordable option for all wood burning saunas - B-Stock.
This item is sold as B-Stock due to cosmetic imperfections. Notable marks include: a small inward dent and scrape on the side opposite the door, scrapes to both sides of the ash drawer, minor scrapes on the ash drawer front, slight warping to the rim, and scrapes on the top where the stones are placed. There is also a small dent to the bottom.
Please refer to the product images for a detailed view of the cosmetic flaws. These imperfections do not affect functionality—the heater is in perfectly usable condition and is offered at a discounted price.
Product Description
The heaters black enamel finish combines stylish modern design with durability and is very easy to keep clean. These high quality heaters are the perfect choice for those looking for a highly durable sauna heater solution. As with all Finnmark heaters, the Narvi range is CE marked and bears the Finnish key flag symbol denoting a product that is at least 95% made in Finland, something no competing brands can boast. Finnmark refuses to stock heaters made in the Far East as we believe a product should be well-built, reliable, eco-friendly and above all, durable.
The Narvi Black 20 continuously burning sauna heater has a large fire grate that improves the efficiency of the stove. The market-leading stone capacity of these stones ensure an excellent löyly and the 10mm steel fire box, again market-leading, ensures you will be leaving this heater to your grandchildren!
Please not that the flue kit and sauna stones are to be purchased separately
We recommend the Kota Insulated Steel Flue / Chimney Kit.
This heater requires 50-80kg of sauna stones. We recommend using 10-15cm Olivine Diabase or Vulcanite Sauna Stones for optimal performance.
