Sure, camping in the winter season makes for lovely sights—but, once the shivers, chills, and frostbite kick-in, you’ll soon find yourself scrambling for warmth!

Luckily, propane heaters come in handy. With their light, portable design and functional heating system, these appliances can keep campers like you safe, warm, and dry throughout an icy excursion. 

Though, before anything, you should know that most of this equipment is designed for outdoor use. In this case, you ought to ask yourself the burning question: Are propane heaters safe to use inside your small, enclosed tent? 

Are propane heaters safe to use in a tent?

It’s generally safe to use a propane heater inside your tent—provided that you’ve followed the safety guidelines, and that you’ve purchased one designed for indoor use. However, since you’re in an enclosed space, always have proper ventilation and a functioning carbon monoxide detector while your device is running.

Propane heaters are equipment designed to keep your body temperature warmer than your surroundings. Most often, these portable, gas-powered appliances are used outdoors, and unlike electric heaters, they don’t need an energy source to work.

Most modern models use “catalytic conversion”—that is, the burning of liquefied petroleum gas (LPG)—to release heat (via convection or radiation); As a result, your surroundings are warmed more quickly and generously, and without much cost, on your part!

However, using a propane heater comes with the risk of emitting harmful carbon monoxide gases. If left unchecked, these devices can pose serious health, safety, and fire hazards.

But fear not! Most modern models are well-equipped against these threats, with features that address concerns on ventilation and flammability. In fact, there are existing designs meant for indoor use, and we’ve compiled a comprehensive list of propane tent heaters for you to check out.

Simply purchase the right model and read through the manufacturer’s guidelines—and you’ll be well on your way to a cozy winter’s night!

What are the risks of using propane tent heaters?

Caution for CO poisoning sign

Propane heaters release Carbon Monoxide (CO) among other gases, as a byproduct of burning fuel. Branded as “the silent killer”, this tasteless, odorless, and colorless gas is difficult to detect—even in high toxic levels—making this a significantly dangerous component. 

  • When absorbed into the bloodstream, this can deprive the body of oxygen, cause dizziness, and ultimately result in carbon monoxide poisoning, if not treated right away.
  • In addition, these devices can start a fire, if knocked-down or used improperly. 

Now, I know all these warnings sound scary—but in reality, you haven’t much to fear! There are only a few, recorded cases of carbon monoxide poisoning among campers, so rest assured, you’re in safe hands, provided that you also practice the same amount of safety. 

Newer-generation models come with various sensors that can automatically detect your room’s oxygen level, as well as regulate your heater’s tipping point, surface temperature, and gas emission. Simply put, these devices can monitor their limits while they function, even as you sleep! 

Furthermore, while carbon monoxide is a prominent byproduct, propane heaters actually produce more water vapor and CO2. Studies add that, as long as you maintain a 24:1 ratio between air and propane, CO emissions will be so low that they’re hardly a threat! 

In most cases, it’s the faulty propane heaters—those with clogged burners, leaks, or outdated technology—that are more prone to causing harm, compared to those with regular maintenance. 

What to look for in tent propane heaters

A carbon monoxide detector

Indoor propane heaters are equipped with features that not only regulate your airflow but also fit perfectly inside tight spaces!  If you’ll be sleeping in a tent, these are your best bets.

Just remember: Each model has its unique specifications, so be sure to do your research on the following: 

Carbon Monoxide Monitor

On the off chance that your heater emits too much carbon monoxide, this safety feature will automatically power down your device. (There are also separate carbon monoxide detectors in the market to purchase, should you want added protection.)

Automatic Timer

Sleep without worry, because with this optional feature, you can set an automatic power-down anytime, and at your convenience!

Overheating Safety Feature

For added safety, propane heaters come with a built-in thermometer that detects overheating. When it senses a dangerously high temperature, your device will promptly shut down before it gets too hot. What a relief!

Tipping Detector

Let’s face it: Tents are generally small, so, naturally, you may knock things over, sometimes—even your propane heater. What can you say? Accidents happen!

But accidents like these can start fires, for a toppled-down propane heater would circulate the air incorrectly. To avoid this, some heaters are equipped with a fall detector that stops the device, once displaced.

Safety tips for using propane heaters in a tent

Most campsites allow the use of propane heaters, just as long as you abide by local regulations. This means you must meet all safety standards, before using your equipment.

Indoor propane heaters are no exception to this rule, as these devices require even more of your knowledge and attention. To get you started, here are some five, quick tips on how to use your device safely:

Use your heater properly.

First and foremost, you must learn how to use your heater.

For starters, you should know how to set up your device. Know that you must first turn off the tank’s gas supply—making sure that your heater exhausts all of the gas coming from the supply line—before fully shutting down the appliance.

In addition, you should follow the manufacturer’s instructions completely, and never leave your heater running when you’re gone. While some models come with automatic timers, it’s still best to shut off your device when unattended.

Keep in mind: It’s not the propane gas itself that causes accidents, but the CO byproduct of its combustion. 

Regularly check your equipment.

Before you book that trip, it’s always best to get your propane heater checked. Whether new or outdated, you wouldn’t want to run the risk of damaged equipment. Simply visit your local hardware store, and have them assess your device for gas leaks or faulty carbon monoxide emissions. 

If you’re not satisfied with your current model’s features, you can always purchase a stand-alone carbon monoxide detector, just in case!

A big tent

Purchase tent-safe models.

This is a big, non-negotiable must if you want to use a propane heater inside your tent. If anything, these versions are meant to fit inside those confined spaces and have added features for stability, mobility, and ventilation. 

Get the right features.

When buying a propane heater, make sure to get the most up-to-date models—if not, at least those with indoor-type safety features (as mentioned earlier). It’s recommended to keep these features running full-time.

Their detectors could save your life since they automatically prevent your heater from overheating, emitting excess carbon monoxide, or causing fires by automatically shutting off your appliance.

Mesh ventilation in tent

Have proper ventilation.

Given the dangers of carbon monoxide poisoning, you must never trap yourself with a propane heater. Carbon monoxide emissions shouldn’t exceed your tent’s oxygen level, thus it’s important to have enough space—that is, for both fresh breaths of air to enter and toxic gases to escape

  • Nylon or Cotton Tents: Most propane heaters work best in single and double-walled tents since they’re often lined with breathable mesh. 
  • Canvas Tents: For these tents, you’ll need a stove jack to let air circulate; Otherwise, it’s recommended to use a tent stove instead of a heater.

Having proper ventilation doesn’t mean your device will be less effective. Rather, your heater will continue to keep you warm; The vents, meanwhile, will simply regulate your tent’s airflow and ensure the proper ratio between CO and oxygen. 

In any case, leave your tent fly slightly ajar (for at least six inches on a windless day) to allow circulation in the tent body.

Position your heater properly.

Using a propane heater comes with two major risks: Carbon monoxide poisoning and fire. Properly positioning your appliance can reduce the threat of both.

To avoid CO emissions, avoid putting your device in an enclosed space. Ideally, you’d want this in the middle of your tent, about one to two feet away from its walls. While modern heaters have an automatic tipping feature, it’s still safer to keep it on a stable, even surface, at least three feet away from other objects.

Meanwhile, to prevent fires, keep flammable objects (such as clothes, camping gear, and sleeping bags) far from your heater’s reach. These devices tend to get hot, and can easily start a fire when knocked over or displaced.

Conclusion

The weather outside sure is frightful—but keeping a propane heater inside would keep it delightful! 

As long as you’ve purchased the right device, read all the guidelines, and properly assessed the risks, your indoor heater is good to go, and can safely be used within the confines of your tent. 

In essence, these appliances have been proven to effectively keep campers warm; So, should you find yourself bound for a chilly winter vacation, well, this just might be the device for you!
