- Indoor Rating
- Rated for indoor and outdoor use
Four thousand BTU on low, 9,000 on high, and rated for indoor as well as outdoor use — that combination is why this is the heater we point ice anglers to first. Nearly every cheap propane radiant unit in this group is outdoor-only, which rules it out of a zipped-up pop-up. This one carries an oxygen-depletion sensor and a tip-over switch and is approved to run indoors, which a shelter with a vent cracked is.
Nine thousand BTU is rated at roughly 225 square feet, and a two-man flip-over is a fraction of that, so most of a trip happens on low with a hand on the knob only when the wind picks up. Radiant heat is what makes it feel immediate: it warms faces and hands rather than the air, which suits the way you actually fish — short sits, plenty of moving between holes.
At 7.1 pounds and about 15 inches tall it takes up the footprint of a bait bucket and sits on the ice beside you. The 1 lb canisters are the real limit: one is good for a few hours, not a night, so a day on the ice means two or three spares in the sled. The tip-over switch is lively too — nudge the unit while sliding to a new spot and it goes out, which is the design doing its job, so set it where you want it and leave it there.
Wind is the thing that changes the math. There's no fan, so in a shelter that's flapping, whoever sits closest gets most of the heat and everyone else gets the leftovers. Point it at knees and take turns.
Pros
- Indoor-rated with low-oxygen and tip-over shutoffs
- 9,000 BTU is plenty for a two-man shelter
- 7.1 lb with a small footprint on the ice
Cons
- One-year warranty, the shortest of the Mr. Heater picks
For a zipped-up pop-up or a two-man flip-over, this is the one to buy: indoor-rated, 9,000 BTU, and light enough to sled in with the rest of your gear.
