Narvi 50 Wood‑Burning Sauna Stove – 50 kW Finnish Heater

Hand‑built on Finland’s west coast by Narvi  -still the only major heater brand that designs and fabricates every component on Finnish soil—**the Narvi 50 is the most powerful wood‑burning sauna stove you can buy in North America. It’s nearly 5/8 inch‑thick steel firebox surrounds a 220‑pound stone bed, effortlessly filling up to 2,500 ft³ with rolling clouds of löyly that last for hours. Rated at ≈ 171,000 BTU/h, the 606‑pound chassis embodies Narvi’s 80‑year “zero‑compromise” philosophy on steam quality and longevity. A panoramic glass door, reversible hinge, top‑or‑rear 6‑inch flue outlet, and serviceable cast‑iron grate all speak to the same engineer‑for‑decades mindset. Backed by a 2‑year factory warranty and free U.S. freight from Sauna Marketplace, the Narvi 50 delivers life-changing Finnish heat to lodges, spas, and serious private builds alike.

Why Narvi 50 Stands Alone

Largest Capacity in the USA – No other UL‑listed or CE‑listed wood stove sold stateside pushes a full 50 kW. That headroom lets you heat big commercial saunas without running the stove at its limit, extending lifespan and giving bathers consistent, soft steam.

Finnish Craft, American Support – Narvi has forged sauna heaters since 1937 and runs its own foundry for absolute control over alloys and welds. Sauna Marketplace backs every Narvi 50 with US‑based technical help, spare‑part stocking, and white‑glove freight coordination.

Stone‑Driven Löyly – With 220 pounds of dolerite, heat is stored inside the rock mass instead of blasting the room with flame. A single splash of water delivers a luxurious cloud that lingers.

Built for Abuse – 10‑15 mm thick furnace plate (triple the industry norm) resists warping; replaceable grates and adjustable hinges keep the stove field‑serviceable for decades.

Flexible Installation – Rear or top 5.7" (145 mm) flue, tunnel‑through‑the‑wall option, and field‑swappable fire‑door swing simplify new builds and retrofits.

Ideal For

  1. Commercial spas & wellness resorts
  2. Hunting/fishing lodges and short‑term rentals serving 8‑20 guests
  3. Large private saunas built from logs, masonry, or high‑glass designs where extra kW offsets heat loss
  4. Off‑grid properties wanting maximum heat per firebox load

Operating Costs & Firewood Tips

Expect ~ 19 lb of split, <20 %‑moisture hardwood for a typical two‑hour service. Load 8 lb to start; add 5 lb once the first bed embers. Maintain heat with 1–2 logs every 30 minutes thereafter. Keep draft calm; roaring flames waste energy and overheat the flue. 

Installation & Safety

  • Floor Load: 1,000 lb+ with stones; verify joist capacity or pour a slab.

  • Ventilation: Provide at least one 4" fresh‑air inlet within 12" of the stove.

  • Heat Shields: Stainless or fiber‑cement, 1" standoff, if framing is combustible.

  • Chimney: Class A insulated rated 600 °C (1,112 °F). Double‑wall black adaptor recommended in‑room.

  • Inspection: Have a certified professional check draft and clearances before first firing.

Shipping & Lead Time

Narvi 50 ships free to the lower 48 on a lift‑gate pallet. Average lead time: 5–7 business days in‑stock or 4–6 weeks direct from Finland during peak season. You’ll receive tracking plus a call to schedule delivery.

Warranty & Support

Narvi Oy’s 2‑year parts warranty covers manufacturing defects; stones and gaskets are consumables. Sauna Marketplace serves as your US‑based liaison for troubleshooting, replacement parts, and wear‑item reorders.
