My husband bought me the Little Buddy portable heater last Christmas. I had no idea tent heaters existed. I also had to ask, are tent heaters safe?
Yes, they are. In fact, many portable heaters are indoor-safe (and safe in tents) so I could stay warm and enjoy the outdoors nearly all to myself.
Get ready to break out the camping gear – if you’ve packed it away. In this article, you’ll learn all about proper and safe tent heating methods.
I’m also going to provide my top picks for tent heaters to keep you warm and cozy while out in the wild on a cold weather camping adventure. Let’s go.
How Do You Stay Warm in a Tent?
There are many ways to stay warm in a tent, from insulation to clothing layers to portable heaters and more, including a small or smaller tent for camping.
Smaller tents are better for winter camping because there is less interior space that needs to be warmed. So, as a first step, start with a smaller tent.
You can help insulate your tent by setting it up in a dry location behind a windbreak, like shrubs or a boulder. Also, place a tarp below your tent.
It’s also a good idea to insulate your floor by placing extra layers, like blankets, beach towels or foam mats on the floor inside your tent.
Cover your tent exterior with an additional tarp to help lock in heat. For extra warmth, have a sleeping bag rated for cold and wear warm sleeping clothes.
Generating Heat in a Tent
Once you’ve insulated your tent to keep heat from escaping, you’ll want to generate heat, where possible.
Use an electric blanket plugged into a portable power station, like the Jackery Explorer, for consistent, stable heat while inside your tent.
You can also bring along HotHands hand and toe warmers and tuck them into your sleeping bag before going to sleep for the night.
If you want to heat your tent without electricity, you can bring a butane or propane powered tent heater, like the Little Buddy from Mr. Heater.
Is it Safe to Have a Heater in a Tent?
Are tent heaters safe? The truth is that there are inherent risks to using any heat source in a tent.
Fuel powered heaters have a fire and carbon monoxide risk. There is also a risk of burning yourself with an electric blanket, if used improperly.
However, if you follow proper safety precautions, you can safely use electric or fuel-powered heat sources inside a tent on a winter camping adventure.
Modern and safe tent heaters have automatic shut-off features for tipping over and low oxygen to help ensure your safety if you fall asleep.
There are risks, but if you’re vigilant and follow safety guidelines you can safely stay warm by using a heater inside your camping or backpacking tent.
Do Tent Heaters Give Off Carbon Monoxide?
Carbon monoxide is a colorless, odorless and tasteless gas produced by burning wood, charcoal, propane, gas and other fuels.
Non-electric tent heaters run on propane or butane, but they are built to efficiently burn fuel so that they are indoor-safe.
However, you should always bring and use a handheld carbon monoxide detector when you use any kind of fuel-powered heater.
Even if a heater is labeled “indoor safe” and has an automatic low-oxygen shut-off feature, all it takes is one malfunction to have tragic consequences.
Although it’s very rare, indoor-safe combustion heaters can glitch. This includes portable propane gas heaters.
This is why it’s so important to ventilate your tent while using a heater and always make sure you have a working carbon monoxide detector with you.
Is it Safe to Use a Propane Heater in a Tent?
Yes, it’s safe to use a propane heater in a tent as long as your heater is labeled as “indoor-safe.” This is very important.
There are many indoor-safe propane heaters that you can safely use inside a tent when camping in cold weather.
However, there needs to be proper ventilation in order for “indoor-safe” propane tent heaters to function properly indoors, including inside a tent.
This means always vent your tent when using a propane heater! Crack one or several window flaps for proper ventilation.
Some propane heaters, including the ones listed below come with an oxygen depletion sensor and automatic tip-over shut-off feature.
These safety features help reduce fire and carbon monoxide risk. Even with these safety features, you should always bring a carbon monoxide detector.
Can You Leave a Tent Heater on All Night?
It is never recommended that you use a tent heater while you are sleeping.
Just like you wouldn’t leave a portable heater or heat source on while you’re away, you also should not use one while you’re sleeping.
In fact, right in the Mr. Heater Propane Heater user manual it states in all caps: “NEVER OPERATE THE HEATER WHILE SLEEPING!”
Tent heater safety is dependent on many things like venting, using a carbon monoxide detector and staying aware while the unit is in operation.
Carbon monoxide levels aren’t the only reason to not operate a tent heater while sleeping. There is also a risk of fire with any fuel powered heat source.
For all of these reasons, we strongly advise against using a tent heater while sleeping inside your tent.
Tips to Safely Use a Tent Heater
Using a tent heater can take cold-weather camping to the next level. Here are some tips for safely using a heater in a tent.
#1: Look for an “Indoor-Safe” Tent Heater
When you purchase a tent heater, look for an indoor-safe heater.
There are many camping heaters on the market that are only meant to be used outdoors. Look for the “indoor-safe” label for use inside a tent.
#2: Seek Out Low-Oxygen and Tip-Over Shut Off
Key safety features to look for when selecting a tent heater include a tip-over shut off mechanism that can help prevent a fire.
Also, you should get a safe tent heater with a low-oxygen sensor and shut-off feature. This will help prevent carbon monoxide poisoning.
#3: Properly Vent your Tent
Indoor-safe heaters for tent camping are safe to operate with proper ventilation.
Combustion heaters need adequate fresh-air flow to operate properly. This means you need to create fresh air flow in your tent.
While opening the tent window flaps in the winter might seem counter-intuitive, venting is the only way to safely operate small tent heaters.
Crack a couple of windows on opposite sides of your tent to maintain a constant flow of fresh air.
#4: Know Where to Place Your Heater
Read your heater manual for instructions on where to place your heater.
A heater should be placed on a flat, sturdy surface and several feet away from any items that could melt or catch fire.
#5: Use a Carbon Monoxide Detector
Always have and use a carbon monoxide detector when operating a heater in your tent – no exceptions.
Be sure that your carbon monoxide detector has fresh batteries and test the batteries before each use (as in, before you leave for your camping trip).
#6: Never Operate a Heater While Sleeping
You should never operate a tent heater unattended or while you are asleep.
If you want a heat source that you can use all night long, consider using heat packs in your sleeping bag or an electric blanket.
