Embrace winter camping with the right supplies to safe and warm. Consider layering winter clothes and getting right boots for winter camping. During winter, campsites are not as crowded as other seasons, so you may be able to enjoy the tranquility at its best and reconnect with nature. Your kids can roam around freely without worrying about cars from other campers.


If you are camping with your kids, safety should be your top priority. Consider unpredictable weather during winter, freezing temperatures could pose a danger to your children. 


A general guideline, temperatures below 30 degrees fahrenheit may be too cold for the human body to withstand tent camping. Your body temperature and your heart rate may drop. Prolonged exposure to the cold can have adverse effects on your health. For this reason, you may require at least a tent heater to protect your family.


Traditional firewood is a good option to warm up, but you may not want to watch the fire all the time. It is just too much work. Do note there are some campsites that do not allow a campfire and you cannot bring a roaring fire inside your tent. So having a safe tent heaters for camping is a more practical solution to keep you warm. It is conveniently easy to start and use anytime you need.

Electric heaters

Types of tent heaters

This is one of the most efficient ways to heat your tent, as it heats up the tent quite quickly. Having an electric tent heater is a safe option as it generates ZERO toxic emissions. This equals less worry about suffocation dangers. Specifically, the ceramic heater does not give out open flames or glowing materials. It reduces the danger of fire. That said, you should still look for an electric heater with an auto shutoff timer. Reason being, it may overheat and risk catching fire if left unattended.


The downside of electric heaters is you will be dependent on electrical power supply, which is a drawback if you are a minimalist camper. So check your campsite to make sure they have an electric hook-up (EHU). Take precaution that you do not use your extension cable from home to connect, as accidents and fatalities can occur. You need a special electrical fitting that comes with a circuit breaker. Take into account the possibility that you could experience a power outage, depending on your campground. This is especially common during the worst weather. So make sure you are well prepared.

Gas heaters

Gas heaters are a popular option as it is a portable heater for camping. You do not need to plug it into anything to function. It generates more heat than the average electric heater. It runs with affordable fuels like kerosene, butane or propane. You can easily carry extra fuel around, as if you are carrying a water bottle. It is great for extended trips, as you can carry and resupply fuel. 

Figure how many hours you plan to use your heater and calculate how much you need to bring. Always bring extra. You need to have proper ventilation inside the tent, with one open air vent. Otherwise, condensation will quickly build up from inside the tent. This will then reduce the temperature in the tent.

Gas heaters are a healthier option, in comparison to electric heaters. They keep the air around you conditioned. Though gas heaters are now safer than they used to be, it is still necessary to practice safety precaution by keeping flammable objects away.


Safety tips for tent heater

A general rule of thumb is to position your tent heater properly, keeping it 3 feet away from anything that can burn. Even though electric heaters are known to be the safest option, if flammable material comes into contact with its heating elements, it can still cause a fire hazard. Remember to keep all liquids away from the heater. It only takes one kick of your foot for your drink to spill onto the heater and cause problems.


Gas heaters on the other hand create carbon dioxide and carbon monoxide. If it reaches a toxic level, it prevents absorption of oxygen to your bloodstream. Do read the instructions on the gas heater provided by the manufacturer on how much ventilation is needed for safe use. 


There should be a vent opened for toxic gases to exit the tent, allowing fresh air to enter. It is not a wise idea to leave the gas heater running , while you sleep. The risk is you may fail to wake up if something goes wrong, endangering others around you.


Tips to stay warm in a tent

It is recommended to use a smaller tent. The smaller the overall square footage of the tent, the less air there will be. The less air, the more effective the heater will be as it minimizes heat loss.

Heating tent with hot rocks

Another simple and cheap hack is to heat the tent with 5 to 10 well-heated stones (the bigger and smoother, the better). Lay the stones 5 to 10 inches away from the campfire to heat the stone gradually. Turn the stones around so that they get adequately heated at all angles. It should take 1.5 hours to be thoroughly heated. 


As it does not retain heat as long as bottles, wrap the stones in several layers of aluminium foil to cool down the stone slowly. Place it in a pan, and put a layer of protection under the pan. Remove the foil layer by layer when it starts to cool, as the heat it retains in the air between the foil layers. 


Another trick is to dig a one foot deep hole. Place the stones inside and cover them with sand. Then you can place your tent over the hole, which will heat up due to the heat in the rocks for the rest of the night. Do use sand, instead of soil as you want to let the temperature rise smoothly. 


Alternatively, you can wrap the stones in a cloth or socks, and spread them at strategic points around the tent.



Types of tent heater

If the tent heater is too noisy, it will make your camping experience uncomfortable. It may disrupt your sleep if you are a light sleeper or worse, disturbs other campers. The louder heaters are ones which use electricity. There are heaters available in the market that offer low noise when working.

Automatic Cut-Off

Some heaters have a dedicated temperature sensor which auto shut off the unit as it overheats. To avoid unnecessary fire accidents, some have the function to automatically cut off after several hours of continuous usage.

Large Base

Heaters with a large base also helps prevent heaters from falling over. For electric heaters, make sure your tent is completely watertight.

Oxygen sensor 

Oxygen sensors are a common feature in gas heaters to monitor the surrounding area. It will shut down if the oxygen level is too low. The sensors will close off the fuel source, which prevents build up of exhaust gases in a small space. This is especially crucial when the tent is closed up tight to keep out the cold.

Tip-over switch 

Tip-over switch is another mechanism that shuts down the heater when it tips over. If it tips over, it can release dangerous levels of gas which may cause a fire to start. This is especially helpful while you are sleeping in the middle of the night.  

Size and weight

For minimalist campers, smaller and lighter heaters make it portable and easier to fit anywhere in the tent. Tents usually do not have a lot of space, so your heater should be as compact as possible. If you are in a large group and have a large tent, then electric heaters are great choices as it heats up quickly and circulates the heat well around the tent.

Heat Output

BTUs (British Thermal Unit) controls how much heat the unit gives out. Gas heaters usually have an output range around 2500 to 20000 or more. If you are using a small tent, then choose a heater with lower BTUs.The bigger the tent, the more output you need to warm up the space. This is useful, if you have a tent designed with multiple rooms. 

If you have less people, it is wiser to get a smaller tent, as less people are generating heat. The higher the BTU, the faster the gas will be consumed. Generally, it is better to get a heater that produces more heat, than one that produces less heat.

To calculate the amount of heat you need for your tent, use this simple formula.

BTU’s of heat needed / hour = Cubic Volume of Tent * Temperature Rise Required * 0.25 (Insulation Factor of a tent)

Here is an example:

Tent size 8 ft * 7 ft’ * 4 ft (average ceiling height) = 224 cubic feet

Forecast is 40 degrees for the low that night and you want to maintain 70 degrees inside the tent = 30 degrees temperature rise

224 * 30 *0.25 = 1680 BTU/hour

For Electric heaters, having adjustable thermostat settings provides flexibility to adjust to a comfortable temperature.
