Best Heaters For Tent Camping [Portable Heater Reviews]

While camping is a seasonal endeavor for some, it’s a year-round passion for many of us! So when the dead of winter approaches and we get that familiar urge to venture into the Great Outdoors, only the best heaters for tent camping will do. The right heater will turn any tent into an insulated, comfy haven in even the most frigid of conditions!

Not just any heater will do. The wrong heater may not circulate heat the way you need it when you need it, and some heaters not made for tent camping could serve as fire hazards if left unattended. There are dozens of heaters for tent camping which have hit the market, but there’s only a select few we trust to warm us up safely and soundly for the coldest of our winter camping excursions.

If you’re in the market for the right tent heater, we’ve got you covered. We’ve parsed through all available options to create our definitive list of The 3 Best Heaters For Tent Camping. We’ve also included a list of frequently asked questions to give you all the information you need to make an informed purchasing decision!

What to Look for Before Buying a Heater for Tent Camping

Before you go browsing the internet or your local department (or hardware) store for a new portable heater, you need to know exactly what to look for. Not all portable heaters are the same and so, it is important to find one that is designed specifically for tents and the outdoors.

Power source

So you’re planning your camping trip and expecting some chills overnight. Well, a heater will help keep you warm inside your tent, but you want to make sure that you have the right type of heater that can be powered to operate. There are two main types of heaters available on the market: propane and electric.

Propane heaters

When it comes to propane heaters, these are powered by burning propane and using the radiant heat that is pushed out from the heating element. You’ll almost always want to get a ventless propane heater, as they are much safer for indoor use. 

Ventless propane heaters don’t require any ventilations to work or maintain their safety. Instead, they intake oxygen from the surrounding air in the room and expels that air back out after it has been heated.

Propane heaters will usually be more compact, portable, and lighter in weight. These characteristics make it a great option for using while camping. However, keep in mind that while the physical heater might weigh less overall, you still have to bring a propane tank to keep this unit powered up.

Electric heaters

Many people prefer electric heaters to use on a camping trip, as they are easier to set up and can be considered “less dangerous.” The danger aspect of a portable heater is usually a non-factor in our buying decision, however propane tanks always pose more of a risk than electric so it is still worth mentioning here.

Electric heaters are great if you have an electrical outlet available on the campsite or you are able to park your vehicle near your tent and have an outlet built into the truck or SUV. Remember to bring an extension cord as most electric heaters will come up cord lengths of about 5 ft at most.

How much heat do you need?

Another very important feature that you want to look at on the box or product details of your heater is how much heat can be produced by the portable heater. If you are camping in a larger tent, you’ll definitely want to find a heater that can fill the space sufficiently and efficiently.

When you look at your portable heater, the BTUs is usually what’s advertised on the packaging for how much heat is being output. Check out the two options below to calculate how many BTUs you should be looking for, or use our general guide that will cover the BTU calculation for most campers.

How to calculate the amount of BTUs you need

If you want to be very specific and technical (after all, we are Techie Campers), then use the calculation below to figure out exactly how many BTUs you are going to need:

Tent Area * 20 BTUs = Needed BTUs

  • Tent Area = Width of tent vs Length of tent
  • 1 BTU = 0.293 watts

Tent Heating Guide

Tent Size

BTUs Needed to Heat Tent

1-2 person tent

1,000 BTUs

4-6 person Tent

2,000 BTUs

8-10 person tent

3,000 – 3,500 BTUs

You’ll also want to make sure that you’re not pushing your heater too hard during your trip, or else you might run into the device shutting down or overheating.

Noise levels

Many times, you’ll find that a portable heater won’t directly say how loud the heater is. Some do include specific decibels in the manuals, however you’ll have to purchase and open the packaging to get this information. Just know that propane heaters tend to be a little bit noisier than electric and you will be hearing it all night if it is turned on. Meanwhile, electric heaters are usually more quiet but some do emit a ringing or metallic noise.

We’ve included noise levels for most of the propane heaters we’ve tested so that you can find the right one for you.

What are the most important features to look for in a heater for tent camping?

While there are definitely parallels between the best heaters for tent camping and the best portable heaters currently for sale, there are some key features and variances to consider in your search for the perfect heater for your camping adventures.

  • Overheating Safeguards – Most quality heaters for tent camping have a tipping feature which will turn your heater off if you kick it over in your sleep. They also usually have an overheating safeguard which will automatically shut the heater down when it starts to verge on becoming dangerously hot. Most tents are extremely flammable and such safety features in a tent heater are not only recommended, but necessary.
  • Portability – Are you a backpacker? Do you have limited pack space for all of your camping accessories? The top heaters for tent camping pack a ton of warming punch into a small constitution, making them easy to carry to and from your favorite campsites.
  • Reduced Noise – If you’re someone who goes camping for the peace and quiet it provides, the wrong heater for tent camping will serve as a major annoyance. Pay attention to how many decibels of sound a heater puts out, especially if you’re a light sleeper. You may get all toasty warm, but it won’t improve your mood much if you can’t sleep.

What are the different types of tent heaters available for sale?

There are three main types of tent heaters to choose from. Each has their own distinct advantages and disadvantages, so be sure to choose the type of heater for tent camping which best suits your particular needs and wants.

  • Electric – An electric heater for tent camping is perfect for short camping trips, but you could run into problems on longer journeys into the wilderness unless your heater has a power adapter and you’re adjacent to a steady power supply. Electric tent heaters can be just as powerful as their fuel-powered counterparts, so they’re definitely a worthwhile option under the right circumstances.
  • Butane – Butane heaters are the longer-lasting of the two fuel-powered heaters on this list. Since butane requires extremely high temperatures to convert from liquid to gas, however, they can be a bit of a struggle to get going in the coldest of winter settings. Once you do get your butane heater fired up, you’ll be extremely happy you did! Butane heaters offer prime heating coverage and usually put out ample BTUs to warm a tent up quickly and efficiently!
  • Propane – A propane heater for tent camping is the perfect match for the coldest winter locales. It burns quicker than butane and will keep its liquid form in the chilliest of weather. Conversely, butane becomes nearly useless in extremely cold weather. While you’ll end up using more propane and costing yourself a bit more in the process, there isn’t a better heating option for tent camping when temperatures dip below freezing.

How many BTUs do I need to warm up my tent?

The best way to get a solid estimate of the right BTU output for heating your tent is first to calculate the cubic footage of your tent by multiplying its height, length, and width.

Gauge the weather you’re going to be encountering while also paying attention to your tent’s particular insulation rating. Assign the conditions a multiplier from two to eight, with eight being a situation where temperatures will dip below freezing and maximum warmth is needed.

Multiply your tent’s cubic footage by this multiplier. If your tent spans 80 cubic feet and conditions are at a legit freezing eight, you’ll need a BTU output of at least 640. However, this is simply a rule of thumb. Pay attention to your own comfort level and the comfort of your camping buddies, adjust your heater to cater to what feels best for the group.

Closing Thoughts

Serious campers don’t wait until the weather’s ideal to do their thing. If you’ve got a love for camping which simply can’t be satiated by a seasonal approach, purchasing one of the best heaters for tent camping will ensure you can camp in absolute comfort at any time of the year!

Regardless of how cold it gets when the sun goes down at your favorite campground, grab one of the three tent heaters listed above and you’ll be as comfy and cozy as can be!
