Primus Mars Radiant Stove System

Jump to: Our Verdict / Features / Specifications

High-efficiency cooking —fast, windproof, and built for the harshest conditions.

Fire Maple says: 

The Mars Radiant Stove System is the most efficient stove ever, offering maximized performance in Alpine conditions. Its radiant burner design enables outstanding performance, superior fuel efficiency, and superior weatherproofing.

Challenge the alpine. With a porous material to mix fuel and house the flame, the burner and the press regulator produces both convective and radiant heat when facing challenges in the real world.

Extreme control of aireflow. All air and fuel mixing occurs inside the stove, allowing the flame to be completely enclosed and protected from wind with the integrated heat exchanger

Maximum Efficiency. The integrated cooking system with built-in heat exchanger efficiently transfers heat to the pot so you can enjoy a quick meal anywhere anytime

Flash Boiling. Boiling 0.5 liter of water in just 1min 40sec even in bizzard condition.

Strong But Quiet. By producing radient light energy, it’s much quieter in use compared to conventional stoves. So you can be more focused on what’s important.

Our Verdict

The Fire Maple Mars Radiant Stove System is built for extreme conditions, offering efficient, windproof performance at a fraction of the cost of similar radiant stoves. The enclosed burner and integrated heat exchanger create a hot airflow barrier, shielding the flame from wind. At the same time, the pressure regulator ensures steady performance even in freezing temperatures or at altitude. It boils 500ml of water in just 1 minute 40 seconds, making it one of the fastest stoves in its class.

At 681g, it’s not the lightest option, but its remote canister design improves stability and keeps the heat away from your fuel source, making it safer for use in cold weather. The infrared heating system boosts fuel efficiency and operates far more quietly than traditional stoves. The Mars is the perfect size for two backpackers sharing a cooking system, making it ideal for dehydrated meals and hot drinks after a long day on the trail. The included pot support also adds versatility, letting you cook other dishes, but the integrated 1.25L pot is best suited for simply boiling water.

The Fire Maple Mars is an impressive alternative for those looking to upgrade to a high-efficiency radiant stove without the premium price tag. Fast, fuel-efficient, and built to handle tough conditions—this is a serious stove for serious adventures.
