“You cannot put a heater inside of a tent! You’ll create a fire! It’s too dangerous!” – if you’ve thought about camping in the Winter and shared that idea with your family, you’ve probably heard this. At least we did, way back then.

And we get it. If you ignore all safety measures, your tent may indeed catch fire, and no family wants that for their children.

But here’s the key part: if you ignore all safety measures.

And you won’t ignore them, right? Right?

That’s why we wrote this article: to show you what tent heaters actually are and what you can do to make sure you don’t freeze to death but also don’t die in a fire.

No more shivering while sleeping – let’s get started.

What Are Tent Heaters?

The most common portable tent heaters are:

  • Propane heaters – these use propane tanks to heat ceramic plates or tubes that radiate warmth

  • Electric heaters – plug-in space heaters, fans, or electric blankets; you’ll need a generator or outlet access for these

  • Catalytic heaters – they also use propane/butane but instead of via flame these heaters heat air through a platinum catalyst reaction

Tent heaters help out a lot when you’re camping in cold weather by:

  • Letting you sleep without shivering

  • Creating a warm place where you can change your clothes without suffering

  • Providing a source of heat during storms

  • Heating quicker than wood stoves

A solid tent heater provides that extra relief when your sleeping bags and blankets aren’t fully doing the job.

Potential Safety Risks

But while a good tent heater is great as we just saw, it can cause problems if you don’t take the necessary precautions.

If you don’t know how to operate one, these hazards can happen on your next camping trip:

  • Fires – as most heaters contain an open flame, knocking them over may ignite your tent fabric

  • Carbon monoxide (CO) – burning propane inside an unventilated tent will decrease oxygen levels inside and increase the concentration of CO

  • Burns – you may get burns if you’re in contact with heated surfaces

But don’t get all worried about these. These risks can be avoided with common sense precautions that we will cover in the article.

Key is never to be negligent when using a tent heater.

Choosing the Right Tent Heater

You’re looking for one that will be great at warming up your tent but also has key safety features to prevent those hazards we just covered.

Let’s take a look at what’s out there.

Propane Heaters

Propane heaters normally heat faster than electric ones

Given their heating power, ease of use, and compact size, it’s not a surprise that portable propane heaters like Mr. Heater Buddy and Little Buddy are very common choices for winter campers.

But are they really worth it?


  • Portable and compact (great for transport)

  • Powerful heating from an enclosed flame

  • Simple to use with control knobs

  • Safety features like the low-oxygen auto shutoff

  • Uses readily available propane fuel

Potential Drawbacks:

  • Risk of fire if accidentally tipped

  • Produces deadly carbon monoxide gas

  • Oxygen depletion hazard in unventilated tent

Electric Heaters

  • Enclosed heating elements reduce the risk of a fire

  • Heated forced air quickly warms tent

  • No carbon monoxide emissions to monitor

  • Blankets provide cozy spot heating

  • Adjustable thermostats make it easy to maintain temperature

Potential Drawbacks:

  • Requires a generator/outlet access for power

  • Exposed heating wires could spark (blankets)

  • If you’re using a smaller heater, you’ll have limited heat output

Key Safety Features to Look For

Regardless of whether you’re going for a propane or an electric heater, make sure you check the heater you’re thinking of buying for these key safety features:

  • Low oxygen auto shutoff – this automatically prevents carbon monoxide poisoning

  • Tip-over auto shutoff – reduces the risks of knocked-over units igniting the material of your tent

  • Overheat/over-temperature protection – prevents melting or catching nearby items on fire

  • ETL/UL safety certification – signals electrical safety compliance from rigorous testing

Using a Tent Heater Safely

Ensuring that your tent has adequate fresh airflow is arguably one of the most important things when using propane tent heaters, or other units that burn fuel. Why?

Because the combustion process to heat your tent consumes the oxygen in the air while at the same time producing deadly carbon monoxide gas.

So what can you you do? Ventilation, ventilation, ventilation:

  • Crack multiple windows and doors open on opposite sides of your tent: this allows fresh oxygen to enter from one side as stale toxic air exits the other side

  • Angle windows towards each end of tunnel tents is also great to create a cross breeze

Without enough ventilation, the carbon monoxide levels in your tent can silently build up to lethal concentrations, causing headaches, dizziness, unconsciousness and even death in extreme cases.

It’s also a great idea to run a carbon monoxide detector to keep an eye on these CO levels

Carbon Monoxide Precautions

Every tent where you’re using propane tent heaters or other fuel-burning heaters must have a carbon monoxide alarm that works.

  • Test the batteries before your camping trip to make sure it’s working

  • Position the CO detector near the top of your tent since the gas rises as it’s slightly lighter than air

  • An alarm signals dangerously high carbon monoxide levels above 70 PPM, meaning you should turn off the tent heater and ventilate the space immediately until the detector clears

  • Keep an eye out for symptoms of CO poisoning including headache, dizziness, and nausea

Placing Your Heater the Right Way

The position of your tent heater is crucial to ensure that no accidents happen. You should:

  • Place it on a flat and sturdy surface, away from walls & camping gear

  • Find a hard surface that cannot tip easily to prevent accidentally knocking the heater over

  • Give ample clearance from flammable nylon tent walls, following guidelines from manufacturers (usually they recommend several feet)

  • Keep sleeping bags, outerwear and backpacking tents away from direct contact with hot surfaces

  • Never place on furniture or surfaces that could catch fire if the heater gets knocked over

Additional Safety Measures

If you want to go the extra mile to ensure safety while using a tent heater in your tent (as you should!):

  • Supervise children and pets carefully around the heater

  • Use securing lines to tie back tent door flaps and prevent disruptive wind gusts

  • Allow hot tent heaters to fully cool for 30+ minutes before changing propane canisters

  • Keep a fire extinguisher nearby just in case

If you adopt these measures, the question of “are tent heaters safe?” will stop being a question.

Heating Alternatives

If you’re still not convinced you want to use a tent heater, worry not: there are some alternatives.

Sleeping Gear

Electric blankets are not a myth

Good sleeping gear like sleeping bags, blankets and insulated pads are great alternatives to tent heaters. While they won’t provide as much heat as a heater, they will make sure you don’t freeze to death in your tent:

  • High-quality sleeping bags retain heat well

  • Electric throws or blankets provide spotwarming without tripping oxygen depletion sensors

  • Closed cell foam pads are great to insulate you from the cold ground

And yes, these are safe (but, just like tent heaters, always follow the manufacturer guidelines).

Tent Insulation Techniques

Besides proper sleeping gear, you can also add insulating layers in strategic places to better retain your body heat:

  • Floor mats below your tent prevent heat loss into cold ground

  • Exterior wind blocking layers retain internal heated air

  • Space blankets reflect warmth back inside

Conclusion and Summary

Yes, tent propane or electric space heaters are safe, as long as you:

  • Use an indoor-safe model with auto shutoffs

  • Follow the manufacturer’s guidelines and operating limits

  • Ensure proper ventilation in your tent

  • Actively monitor the heater at all times
