The Planar Heaters 4kw Portable Diesel Heater is hands down one of the best camping accessories of 2025. Whether you’re tackling frigid winter conditions or dealing with an unexpectedly chilly summer night, this heater provides instant, dry heat that transforms any tent, camper, or overlanding setup into a comfortable space to relax.
Having used this heater for years across a wide range of conditions—from rooftop tents to ground tents and everything in between—I can confidently say that its build quality, efficiency, and overall performance are second to none…
As I discuss in my Planar Diesel Heater Review, one of the best features of the Planar 4kw heater is its rugged and portable design. It’s housed in a crushproof, rain-resistant case and is built to withstand the difficulties of off-grid adventures. The result? It’s a reliable companion for overlanders, hunters, ice fishers, and winter campers.
This heater runs on either diesel or kerosene and operates off a 12V DC power source, which means it’s perfectly suited for vehicle-based camping setups. The wired remote controller makes it easy to adjust heat settings without fumbling around in the cold (or leaving your sleeping bag), and with an air intake filter and silencer, it operates smoothly and quietly—which I appreciate when I need a good night’s sleep.
Efficiency is another key reason why this heater stands out. Despite its powerful 4.0 kW (13,600 BTU) heat output, it sips fuel conservatively, burning just 3-4 liters of fuel for 8 hours of continuous operation. This makes it incredibly practical for multi-day trips where fuel conservation is essential.
It’s also one of the few portable heaters that can handle high-altitude camping up to 8,200 feet, so you get reliable performance even in mountainous regions where many heaters struggle. And with a weight of 33 lbs, it’s manageable enough to move around, and its compact 25″ x 19″ x 19″ footprint means it doesn’t take up too much space in your gear setup. There’s even an arctic version of this heater, which you can learn more about in my video below:
Beyond the technical specs, what really makes the Planar 4kw heater one of the best camping accessories of 2025 is how much comfort it adds to any adventure. There’s nothing quite like climbing into a warm tent after a long day on the trail, and this heater makes that possible in even the most challenging conditions. Unlike propane heaters, which add moisture to the air and can lead to condensation inside your tent, this diesel heater produces dry heat, keeping your gear and sleeping space warm without excess humidity. Nice!
