Description

Wood Sauna Stove with Exterior Firewood Feed

The Harvia M3 SL allows you to enjoy two-room sauna experiences. While one bather relaxes in the sauna, another can load firewood from outside the room, keeping the heat and steam uninterrupted. Its cast-iron-framed glass door showcases the glowing flames, adding a classic sauna ambiance.

Perfect for small to medium saunas, this stove combines efficiency, convenience, and traditional Finnish performance.

Heating Performance

The 16.5kW wood-burning stove heats sauna rooms 212–459 cubic feet efficiently. Its design ensures steady, long-lasting warmth while maintaining the authentic wood-fired sauna experience.

Highlights:

• Heats two rooms simultaneously

• Efficient air circulation for even temperature

• Deep, radiant heat that electric heaters cannot replicate

Stone & Steam Features
