I’ve been using a diesel heater for some time now, and I honestly can’t imagine camping and overlanding without one. The days of being cold are over with the instant, dry heat of a diesel heater!

Even if you don’t do much (or any) cold weather camping, having a diesel heater in your kit is a fantastic amenity for those chilly summer nights while camping. I’ve been in some hot spots over the years – Death Valley among them – and even in locations like that, a heater is often necessary at night.

So, what are the top diesel heaters of 2023? Let’s find out!

Portable Diesel Heaters By Planar In the Car Ready For Winter Camping

This 4kw portable diesel air heater from Planar Heaters is a self-contained unit that comes with everything you need to get instant, dry heat in your tent, camper, van, or other sleeping accommodations.

The bright yellow case is easy to see at night and offers crushproof protection and rain resistance, so you don’t have to worry about tough weather conditions causing it harm.

This is a dual-fuel unit and runs on either diesel or kerosene, both of which require 12-volt power as well. Either way, you can enjoy dry heat for about eight hours from roughly one gallon of fuel.

Planar has equipped this portable diesel heater with a silencer to minimize noise. There’s an air intake filter to keep the unit breathing, and a remote-wired controller is included so you can adjust the heater’s output without having to get out of bed. That’s a nice touch!

As I explain in the video above, I’ve had this unit for about a year now, and I’ve used it in all sorts of conditions in all kinds of locations. Each time, it worked like a charm and provided instant dry heat for my rooftop tent. And with 4kw of power available, there’s enough output to heat my tent and a buddy’s tent at the same time.

Plus, at 25′ x 19′ x 19′ and 33 pounds empty, this heater is easily portable and doesn’t take up much space in the bed of my Jeep Gladiator. When you’re overlanding, space is at a premium, so gear with a small form factor is appreciated.

All in all, I’ve had a great experience with this heater. The build quality, ease of operation, quiet operation, and incredible heat output are just a few reasons why this heater is on our list of the top diesel heaters of 2023! You can even get a 2kw version (shown above left) if 4kw is too much.

The heater comes with an installation kit, an operating manual, and your choice of an analog or digital controller. Likewise, the heater has a self-adjusting system so you can operate it at elevations ranging from sea level to 8,200 feet.

It’s a small unit, too – 12.76″ x 4.65″ x 4.69″ and 15.7 pounds.
