Winnerwell® Marsfire External Air Wood Burning Tent Stove

Safer Heat for Enclosed Tent Living.

Designed to reduce oxygen depletion inside enclosed tents, the Winnerwell® Marsfire Stove offers a safer alternative to conventional wood-burning tent stoves.

Traditional tent stoves draw combustion air from inside the shelter — gradually consuming oxygen and increasing the risk of smoke buildup in confined spaces.

The Marsfire’s patented External Air Intake System changes that.

By pulling fresh combustion air directly from outside the tent, the stove helps maintain safer oxygen levels inside your shelter, reduces indoor smoke accumulation, and creates a more stable burn — especially in cold, low-ventilation environments.

For winter camping and hot tent expeditions, this means:

• Less oxygen depletion inside the tent
• Reduced risk of smoke backflow
• More efficient, hotter wood combustion
• Greater peace of mind during overnight heating

Built for serious cold-weather performance, the Marsfire delivers reliable heat while improving in-tent safety compared to conventional wood-burning tent stoves.

Note:

• Not recommended for use with a 90° flue pipe, as sharp airflow restrictions may affect combustion efficiency.

• When using inside a tent with a groundsheet, it is strongly recommended to use the optional heat shield accessory to protect the tent floor and underlying surface from excessive radiant heat from the stove base.
