Made in Finland. Compact form. Classic fire-fed heat.

The Harvia M3 Wood Burning Sauna Heater is the compact entry point into Harvia’s wood-burning lineup — purpose-built for smaller sauna rooms up to 212–459 cubic feet. Made in Finland from premium stainless steel with a glass door, the Harvia M3 delivers everything that defines a genuine traditional sauna experience: the crackle of a real wood fire, the warm amber glow through the glass, and the deep, enveloping heat that only a wood-burning stove can produce. No electricity required — just wood, fire, and the ritual.

Construction & Durability: The 10mm thick fire chamber is engineered for long-term durability under the extreme temperatures and humidity of regular sauna use. The stainless steel body resists corrosion and holds up season after season in both indoor and outdoor sauna cabins. The large stone bed and stainless steel air-flow spoiler work together to deliver consistent, efficient heat distribution throughout the cabin — whether you’re running a wet or dry session.

Wet or Dry, Your Choice: Pour water over the stones for a soft, long-lasting löyly steam experience, or run it dry for a classic high-heat session. Adjustable feet simplify installation and allow precise positioning of the smoke outlet height to suit your cabin setup.

This complete Harvia M3 kit includes everything needed for installation from day one: the heater, chimney, sauna stones, smoke pipe, rain cap, rubber rain flange, installation hardware, and ceiling lead-through components.
