Six heaters below were checked on Amazon on October 10, 2026. The Opolar electric heater and two other old picks are gone from Amazon, and the old short heading names no longer match live listings, so the list is shorter. Heat ratings come from the Amazon titles and older page text. A tent heater is a fuel-burning appliance, so read the maker manual for ventilation rules.
A cold tent can ruin a trip. A small heater can make the difference, but a tent is also the easiest place for carbon monoxide to build up. Here is how to pick a heater and use it safely, plus six models to look at.

Types of Tent Heaters
- Radiant propane heaters. Small, no power needed, use 1 pound cylinders or a hose to a bigger tank. See our guide to propane heaters.
- Butane and mixed gas mini heaters. Very light. Butane does not vaporize near freezing, so they fail in real cold.
- Electric heaters. No fumes, but they need a power hookup.
Looking ahead, tent heating is getting safer and smaller. Low-oxygen shutoffs, tip-over switches and battery carbon monoxide alarms are now standard advice, and more campers are moving to powered sites with small electric heaters. The catch is that cold-weather camping keeps growing, and so does the number of people who take a gas heater into a sealed tent to sleep.

The Mr. Heater Buddy is the best-known tent heater, with more than 29,000 ratings and a 4.7 average on Amazon. The older page described it as a radiant propane heater that runs between 4,000 and 9,000 BTU, with shutoffs for tip-over, low oxygen and a pilot that goes out.
Price on Amazon: $69.99 | 4.5 stars from 8,810 ratings (checked October 10, 2026)
The Little Buddy is the small version at 3,800 BTU. The older page said it covers about 95 square feet, which fits a two-person tent.
Price on Amazon: $131.57 | 4.5 stars from 1,146 ratings (checked October 10, 2026)
The Hunting Buddy is a 12,000 BTU portable radiant propane heater in camo. It costs more and puts out more heat than a normal tent needs, so it suits a big canvas tent or a cabin.
Price on Amazon: $25.99 | 4.3 stars from 1,170 ratings (checked October 10, 2026)
The Campy Gear Chubby is a 9,000 BTU propane heater and stove in one, with a low price. It has over 1,100 ratings at 4.3 stars. Check the listing for shutoff features before using it in a tent.
Price on Amazon: $36.10 | 3.8 stars from 66 ratings (checked October 10, 2026)
The Mrinb is a mini propane and butane heater with a stand. It has a 3.8 rating from only 66 ratings, so read recent reviews first.
Price on Amazon: $59.99 | 4.2 stars from 7,878 ratings (checked October 10, 2026)
The Honeywell HeatBud is a small ceramic heater with two heat settings and nearly 8,000 ratings. It needs an outlet, so it is for powered campsites, not backcountry.
The risk to watch is carbon monoxide in a closed space. A tent has little air to spare, and a heater that burns fuel uses it up. Expect more campground rules and more reminders from fire agencies. Run the heater only while awake, keep two vents open and carry a battery alarm that is made for camping.
Tent Heater Safety
- Carbon monoxide. Use a battery alarm made for camping and keep two vents open, one high and one low.
- Awake only. Turn the heater off before you sleep. A warm sleeping bag does the night shift.
- Fabric. Use only in a tent that says it is flame-retardant, and keep the heater at least 3 feet from walls, bags and gear.
- Stable base. Put it on a flat, firm surface that cannot tip.
- Safety shutoffs. Look for tip-over and low-oxygen shutoff.
- Fuel. Change cylinders outdoors, away from flames, and store them upright.
Sizing
A rough rule is 20 to 40 BTU per square foot in cold weather. A 4,000 BTU heater suits about 100 square feet, which is a normal two-person tent. A large family tent of 200 square feet or more needs 9,000 BTU or more, and the heater should still be used for short bursts. See our guide on how to choose the right size space heater for the method.
Cold-Weather Tips
- Pick propane for freezing temperatures. Butane stops working near 31 degrees Fahrenheit, and propane works far below that.
- Warm the tent for 20 minutes before bed, then turn the heater off.
- Use an insulated pad. Much of the cold comes from the ground.
- Venting a tent also fights condensation, which makes everything feel colder.
FAQ
How many BTUs do you need for a tent?
About 4,000 for a 2-person tent and 9,000 or more for a large one.
How warm is too warm?
A tent only needs to feel comfortable, around 55 to 65 degrees Fahrenheit while awake. Hotter than that wastes fuel and raises the fire risk.
Why does the shutoff matter?
A tip-over or low-oxygen shutoff stops the flame if the heater falls or the air gets thin.
Will it handle a large tent?
Match the BTU rating to the floor area, and look at the tent label for any fire rating. A park ranger can tell you about local fire rules. A home reading of the air helps too, see air quality testing.
Final Word
The Mr. Heater Buddy is the safest bet for most campers. Use it awake, with vents open and a battery alarm, and leave the heating to the sleeping bag at night.
What happens next: expect lighter propane units, more rechargeable electric options for powered sites and better sleeping bags that cut the need for a tent heater at all. For most trips, a warm bag and a short burst of heat before bed is the safest plan.
