The Osburn 3500 is a large, EPA-certified wood stove that delivers up to 95,000 BTU/h—ideal for heating spaces up to 2,500 ft². With low emissions (1.75 g/h), up to 8 hours of burn time, and a rugged design, it’s perfect for efficient whole-home heating with fewer reloads. A large ceramic glass door offers a clear view of the fire, while the oversized 2.9 ft³ firebox handles logs up to 22″ with ease. A built-in blower helps distribute heat evenly for maximum comfort.
