I’ve had my Planar Heaters 4kw diesel portable heater for several years now, and it has proven to be one of the best additions to my overlanding kit that I’ve ever made. This thing is bulletproof, ultra-efficient, works in all sorts of environmental conditions, and is easy to use, to boot.

Now, I’ve used my heater almost exclusively for tent camping (I have a diesel air heater from Planar Heaters installed in the nose of my Turtleback Expedition Trailer to heat my rooftop tent). But, using a diesel portable heater for tent camping isn’t the only application for this thing. Let’s dive into a few other uses for a heater like this and explore why it’s such a sound investment!

Use a Diesel Portable Heater as a Backup for Your RV

Camping in an RV, travel trailer, fifth wheel, or campervan is a lot of fun. There are unparalleled comforts, not the least of which is a propane-fired furnace to keep your rig toasty warm. But what happens if the furnace malfunctions?

I’d suggest a diesel portable heater like mine as the ideal option! My 4kw diesel heater has more than enough heating capacity to keep a 30-foot RV warm. When you’re camping in the winter, in particular, having a backup heating source isn’t just vital for your comfort but it’s also necessary to ensure the water system in the RV doesn’t freeze.

Heck, even in the spring, summer, and fall, nighttime temperatures can get uncomfortably cold, so having a secondary heating source in your RV just makes sense. We can do all the preventative maintenance we want on our RVs and take them in for regular service, but you simply never know when a system like the furnace is going to go out. Enjoy greater peace of mind with a diesel portable heater at the ready!

A Diesel Portable Heater is Great for Emergencies at Home

I’m grateful to live in the U.S. where we have a reliable power grid (well, mostly…). But, again, you never know when the power is going to go out due to poor weather or a natural disaster. Heck, even freak accidents like an animal causing a transformer to blow up can cause blackouts that impact thousands of people.

If one of these events happens in the colder months, a diesel portable heater can come to the rescue. Now, I know a 4kw heater won’t keep an entire home at 70 degrees in the winter, but you could at least put it outside the kitchen window and vent it inside to keep the sink pipes from freezing.

And since units like the one I have from Planar Heaters are highly portable and easy to use, you could rotate it from the kitchen to the bathroom to the laundry room and so forth, keeping each area warm to prevent freezing pipes (assuming you have a window to vent the heater through, of course).

These heaters aren’t just useful for emergencies at home, though. In areas where the winter cold can be brutal, having a diesel portable heater in your vehicle could be a lifesaver. Just set the unit outside, vent it through a window, and enjoy instant, dry heat in your vehicle if you get stuck, run out of gas, or get into an accident with no immediate rescue in sight.

Tap into the Efficiency of a Diesel Portable Heater

Aside from being usable in all sorts of situations, a diesel heater is extremely efficient. My Planar Heaters unit can run all night long (about eight hours) on less than a gallon of fuel. If I have both of my two-gallon RotoPax filled with diesel when I leave on a camping trip, I’ll get roughly four full nights of sleep with my diesel heater on all night. Nice!

These heaters are also extremely efficient at heating a space quickly. As I mentioned earlier, they produce instant, dry heat, so as soon as you turn it on, you get toasty warm air inside your tent, RV, house, and so forth, with immediate improvement in the temperature of your surroundings.

Better still, you can control the temperature and fan speed using the wired remote (on my heater, anyway), so you don’t have to venture outside to make any adjustments.

Plus, these heaters use very little power – mine uses a 12.8-volt lithium battery – so you don’t have to worry about losing power in the middle of the night or constantly charging the battery so you can run your heater. I can’t speak for other brands of diesel heaters, but my Planar Heaters unit has been a complete breeze to use without any worry of failure.

A Diesel Portable Heater is a Safe Heating Option

Above all, diesel heaters are safe to use. Sure, efficiency ease of use, and wide applicability are nice, but if you can’t use a heater without fear of carbon monoxide poisoning, what’s the point?!

If you want to learn more, please visit our website Portable Diesel Air Heater.

What makes these heaters safer is that they sit outside whatever it is you’re heating and vent the warm air inside. According to Planar Heaters, this is part of the reason why you don’t have to worry about carbon monoxide poisoning. The other component of this is that the combustion chamber is completely sealed. This combination of factors makes diesel portable heaters (from Planar Heaters, anyway) completely safe to use in all the applications noted above.

Why a Portable Diesel Heater for Camping is So Worth It

There are few things worse on a camping trip than shivering through a cold night. Sure, you can slide into a sleeping bag to keep warm, but getting out of your bag in the morning inside a cold tent (or in the middle of the night to answer nature’s call) is downright miserable. Some folks prefer having a wood stove in their tent for warmth. Others use electric heat, like electric blankets, to keep the chill away. There are problems with these kinds of heat sources, though. On the one hand, a wood stove has to be tended throughout the night. On the other hand, an electric blanket doesn’t do anything to heat the space inside the tent. So, what do you do? The simple answer is this - invest in a portable diesel heater for camping!

What is a Portable Diesel Heater for Camping?

There’s really no mystery to portable diesel heaters. As the name implies, it’s a heater powered by diesel that you can easily move from one place to the next. Diesel heater manufacturers have devised a pretty ingenious system to achieve this portability factor. For example, Planar Heaters offers diesel air heaters that come inside crushproof and rain-resistant cases. On the one hand, this kind of durability means you’ll get years of use out of the heater without worrying about the rough-and-tumble nature of camping and overlanding and whether your adventures will cause damage to the heater. On the other hand, the integrated handle in heaters like this allows you to grab and go as you please. Pop the heater in the bed of your truck for the drive up to your favorite campsite, then grab it and set it up next to your tent in a flash for a nice, cozy, and warm evening of sleep.

The components inside a portable diesel heater are pretty straightforward. Aside from the heater, there’s a fuel tank, a combustion chamber, and a heat exchanger. Some models, like those from Planar Heaters, include a silencer to minimize the operational noise of the unit. There’s also ductwork that funnels the warm air from the heater inside the tent. Most portable diesel heaters run on 12-volt power, so you need a battery on hand to run it (in combination with the diesel fuel, of course). But apart from connecting your heater to an electric power source, running the duct inside your tent, and firing it up, there’s really not a lot of setup involved.

What Brand of Diesel Heater is Best?

The brand of portable diesel heater we offer is Planar Heaters, which is pictured throughout this article. While there are a lot of quality diesel heaters out there, there are also a lot of really terrible ones made from cheap materials imported from China. Planar Heaters has been in the business for a long time, and has established itself as one of the premiere heater distributors in North America. Planar Heaters stands behind its products with a two-year warranty that covers free parts replacement, in-shop warranty service, and if necessary, product replacement with a refurbished, fully operational unit. These heaters are built like tanks, too. The quality of the components is second to none, and the design and functionality of these heaters further highlight why Planar Heaters is such a good choice.

Advantages of a Portable Diesel Heater for Camping

Investing in a portable diesel heater for camping gives you the obvious benefit of having a reliable heat source for your adventures. But these heaters provide many other tangible benefits, too. For example, Planar Heaters portable diesel heaters give you the flexibility of running on either diesel or kerosene. In either case, you still need a 12-volt power source, but you have the peace of mind knowing there’s some flexibility with the type of fuel you use. Another benefit of these heaters is that they operate at exceptionally high altitudes - up to 13,700 feet above sea level, depending on the model. This is possible because of the efficiency of Planar Heaters. High-altitude camping means there’s less oxygen, which reduces the efficiency of any diesel heater. However, the Planar models we have in stock are still capable of producing enough heat output to keep you warm, even at extreme altitudes.

You also have some choices when it comes to the heat output of your portable diesel heater for camping. For example, Planar Heaters offers2kw and4kw models. The 2kw model is rated for use up to 8,200 feet, while the 4kw model gives you reliable heat output up to the 13,700-foot figure mentioned earlier.

You can pair your 2kw or 4kw Planar portable diesel heater with either a five-foot or ten-foot duct. The duct moves the heated air from the portable heater into your tent or RV. This reveals two related advantages. First, since the unit sits outside, you don’t have to worry about it taking up precious space inside. Second, and more importantly, with the unit outside, there’s much less risk for carbon monoxide poisoning to occur.

In fact, no exhaust gasses or carbon monoxide are mixed with the heated air. As the warm air blows into your tent or RV, you can rest assured it’s clean, safe, and healthy air that heats the space and nothing more.

The type of heat produced by a portable diesel heater for camping is an advantage, too. These heaters create instant, dry heat, so not only do you get immediate relief from the cold, but you also get the benefit of dry heat. There’s no worry about your heat source creating a condensation problem! As if that isn’t enough, these Planar Heaters models come with a wired remote that allows you to adjust the heat output without getting out of bed. Roll over in the middle of the night, crank it up or turn it down to your heart’s content, roll back over, and go back to sleep! It’s also worth mentioning that these heaters use around half a gallon to one gallon of fuel in an eight-hour period. With that kind of efficiency and output, you can have heat all night long without worry that your heater will sputter and shut off due to a lack of fuel.

Safety Features of a Portable Diesel Heater for Camping

The biggest safety feature of a portable diesel heater was mentioned above - since it sits outside, there’s less risk of carbon monoxide poisoning. 

But more than that, having the heat source outside also means you don’t have to worry about accidental fuel spills inside your tent or RV, nor do you have to worry about fire risk inside your shelter or the potential for burn injuries.

Other safety features include the following: 

  • A large filler cap for the fuel tank to minimize the risk of fuel spills
  • An integrated air filter to ensure the heater has clean air to operate
  • An available bright yellow body color to reduce tripping hazards
  • A large base width to prevent the unit from tipping over

Of course, these safety features and the excellent heat output are available in a variety of applications. You can use these heaters to warm up your tent or yurt, your teardrop trailer or travel trailer, or your RV, boat, or ice fishing hut, for that matter. Furthermore, a portable diesel heater for camping can be a nice backup heat source at home in the event of a power outage. While a 2kw or 4kw heater won’t heat your whole house (unless it’s a tiny house!), you could duct the heat into the kitchen or utility room to prevent pipes from freezing and do so in a completely safe manner.

Better Heat for a Better Camping Experience

There is no need to continue suffering through chilly nights on your camping trips. With the efficiency and functionality of a portable diesel heater for camping, you can easily take warm, dry heat with you wherever you go in whatever shelter you like to use.
