One of the best things about the Buddy heater that not all heaters have is a carry handle. Sure, this makes it easy to carry to your campsite, but it’s also good for carrying the heater around your tent when it’s pumping out heat.

The heater is also super simple to use. Lighting up is as simple as rotating the pilot knob, thanks to an integrated Piezo sparking mechanism which handles everything else. No more messing around with matches and freezing cold hands!

Best Safe Tent Heaters – Buyer’s Guide

Is It Safe To Put A Heater In A Tent?

Many campers, especially hunters who hide out in especially cold conditions, have been known to use a heater. Whether electric or gas-powered, they’re a popular choice for keeping warm.

You can use either heater in a tent safely, but both kinds pose their own risks. It’s imperative to heed the following safety precautions: failure to do so could result in serious injuries or even death. Protect your loved ones and stay warm safely!

Any heater can be deadly used in a tent if not done correctly, even if it proclaims to be safe for use on camping trips. Be particularly careful and avoid using them around young children or pets, who have difficulty staying away from danger.

Preventing Risks

Gas heaters, usually powered by natural or propane gas, can produce carbon monoxide in larger than average quantities. This is dangerous for humans to inhale: bringing one of these into your tent without taking caution could be fatal.

A tent usually has a built in vent or two that you should absolutely open. Consider also compromising your wind protection by unzipping your tent flaps a little for improved airflow. It’s worth it, and it won’t let too much of the heat escape.

You should never leave any kind of heater on overnight, as that poses a serious fire hazard. The CO2 production involved in powering a gas heater makes this even more necessary. Only run it for an hour or two, and never fall asleep with it on.

Prolonged exposure, while you’re not awake, means you could miss early signs of carbon monoxide poisoning. Symptoms include dizziness, drowsiness, nausea, confusion or a headache and should be taken very seriously.

If you experience any of the above symptoms while camping and you happen to be using a gas heater in an enclosed space, leave your tent. Open up all of the zips and allow air in, turn off the heater and seek medical attention immediately.

Electric heaters can also be dangerous, as they are more lightweight and easier to accidentally disturb or knock over. Left unattended, this could cause a fire if the proper preventative measures haven’t been taken by manufacturers.

They are also, as all fires tend to be, extremely hot, and will absolutely burn you if you touch them. It sounds easy to avoid, but remember, tents are more cramped than your house and tripping over things is more likely.

However, we would recommend them much more than gas heaters as they do not involve combustion. Rather, they usually involve the heating of ceramic cylinders that then project heat, which although potentially harmful, isn’t actively dangerous.

Above all, it is advised that you prioritize taking thermally-rated sleeping bags and pack appropriate clothes. Making sure to eat and drink plenty before bed will also aid your body in keeping warm while you sleep.

Features To Look Out For


Aiming for a small or ‘portable’ heater is your best bet. This will reduce the amount of space it takes up both in transit and in your tent! However, that doesn’t necessarily mean it will be any less powerful or good at its job.

Oversized heaters pose more of a fire risk than their littler counterparts. Knocking them over exposes a greater area of your tent to a fire hazard. Plus, larger gas heaters produce more carbon monoxide, which you want to avoid where possible.

If your tent is for more than four men, or has separate rooms, you can probably afford to opt for a bigger heater. Ensure everything is ventilated as much as possible at all times, though!

Safety Features

Electric heaters that feature built in tip-over detectors are best. Immediately cutting power to the heater, they vastly reduce the possibility of a fire or damage to your tent. Camping equipment can be flimsy and flammable at the best of times!

Gas heaters with an inbuilt ODS or oxygen depletion sensor are the best to use inside a tent. They will alert you if you have not ventilated sufficiently and are putting yourself at risk of carbon monoxide poisoning.

Of course, you should make it your priority to avoid covering or blocking the heater. Place it as far away from your tent walls as possible! This ensures it cannot be a fire hazard, or exposed to water or damp from the outside of the tent.

Ventilation, obstructions and observation are key words to bear in mind if you’re going to use a heater in your tent.  AKA: that there is maximum airflow, the heater itself is unobstructed, and you never leave it turned on unattended.


Traditionally, space heaters (the electric kind) don’t make any detectable sound at all, unless they oscillate. In this case, you’ll probably hear the faint hum of the rotating motor. It isn’t difficult to tune out at all and could even be soothing!

Gas heaters are constantly burning, though. Although you might not be able to visibly see this process, you’ll certainly be able to hear it in close proximity. This is good, as it will discourage you from leaving it on all night by accident!

Best Safe Tent Heaters – Frequently Asked Questions

How can you keep warm in a tent at night without a heater?

Looking for old fashioned methods of staying toasty, that aren’t dependent on pitching up at a campsite with electricity? There are other ways to stay warm in your tent, which also have the benefit of being much cheaper than a heater.

Maybe it sounds obvious, but do not underestimate the power of bringing several blankets. Wrapping yourself up inside your sleeping bag, like a caterpillar in a cocoon, is the cheapest way to get warm.

Use towels to line the entryway and sides of your tent, and ensure everything is properly zipped down when you turn in. This will protect you from wind and keep out any bugs, which is an added perk.

Bring along a tent mat designed purposely for all-weather camping, typically made from foam. It will raise you slightly and protect your back from the cold, damp floor beneath. It may help with contributing a bit of warmth too!

Though not traditionally used in the USA, take a leaf out of the book of UK campers! Why not pack a hot water bottle or five? Simply fill the covered, rubber bottles with boiling water before bed, pop them in your sleeping bag and feel the heat.

You could improvise this with a non-plastic bottle lying around your house. Make sure to wrap it in a dish towel or blanket to prevent contact burns. Their exteriors can get mighty hot once full!

Packing your coziest thermals and thickest socks is always a good idea. They don’t even have to take up much room in your rucksack if you pack neatly enough! If you’re taking boots, for instance, roll them up and pop them inside. Voila!
