More miles. A warmer camp.
Bring warm air to your tent, rooftop tent or camper when the weather turns cold. The OX Diesel Heater X5 packs up to 5 kW of heat into a narrow, portable body weighing 22.5 lb (10.2 kg).
Its compact format suits vehicle-based camping: carry it to your campsite or plan a suitable external mount. Keep the heater outside and route warm air inside through the duct.
Developed by South Korean engineers. Automatic climate control, wireless operation and a quick-connect fuel system make camp heating easier to manage.
The wireless remote stores on the heater's magnetic holder.
Set the temperature. Stay inside.
AUTO climate control adjusts heating output toward your selected temperature from 46–97°F (8–36°C). As conditions change, the heater adjusts its output so you spend less time changing settings.
Use the wireless remote from inside your tent. No trips outside to adjust the heater—and no firewood to add or ash to clear away.
Stop & Go is a separate function: it stops heating and restarts it as needed. AUTO modulates heat output rather than switching heating fully off. Fuel use depends on the mode, weather and heat demand; there is no fixed savings percentage.
Connection detail shown. The X5 package includes a 2.6-gallon (10 L) tank; tank appearance may vary.
Fill the can. Click in the fuel line.
The X5 draws diesel from a separate 2.6-gallon (10 L) tank. Fill the tank, connect the fuel hose at the cap and complete the startup procedure. There is no built-in heater tank to fill, so you do not have to transfer diesel into the heater.
The quick-connect fitting makes attachment straightforward. A check valve helps reduce fuel spills when disconnecting the hose, making packing up cleaner and easier.
Turn the heater off and let it cool before refueling. Follow the manual for fuel handling and first-use priming.
One coaxial supply-and-return duct connection on X5.
The heat comes in. The heater stays out.
A compact coaxial duct routes the warm-air supply and return through one connection. The heater body, diesel tank and exhaust stay outside your tent or camper.
Plan the duct route for your ground tent or rooftop tent before setting up. Keep the air path clear and the exhaust away from the return-air intake, doors and windows.
Ready to build your warm camp.
The heater, controls and connections—in one portable system.
Two carrying bags help keep the heater, tank and accessories organized.

X5 or X10?
Choose X5 for its compact, 22.5 lb (10.2 kg) body, one heating core and 2.6-gallon (10 L) tank. X10 offers up to 10 kW with two selectable heating cores and a 5.3-gallon (20 L) tank. Both have AUTO climate control, a wireless remote and CO sensors in the heater and remote.
Place the heater outdoors. Use a stable, noncombustible surface or a suitable external vehicle mount. Keep the heater, fuel tank and exhaust outside your occupied space.
Connect air, fuel and power. Install the supply/return duct and exhaust as shown in the manual. Connect the fuel hose to the filled tank. Use a suitable 12V DC source or the supplied power unit with its native U.S. plug.
Choose your comfort setting. Use the wireless remote to select AUTO and your target temperature, or choose a manual heat level. Follow the manual for first-start priming.
Let it cool before packing. Shut down using the controls. Keep power connected until the cooldown cycle finishes and the fan stops.
Keep exhaust away from doors, windows, occupied areas and air intakes. Maintain ventilation and a separate working CO alarm. Follow the supplied manual for clearances, installation and fuel handling.
Before your next trip
Can I use X5 with a rooftop tent or camper?
Yes—X5 is a portable heating option for vehicle-based camping, including a suitable rooftop-tent or camper setup. Keep the heater, fuel tank and exhaust outdoors and route air through the correct duct connection. An external vehicle mount must be suitable for the installation; mounting hardware is not included. Check duct routing, clearances and exhaust placement in the manual.
Does X5 include the wireless remote and AUTO?
Yes. X5 and X10 both include a wireless remote and AUTO climate control. X5 is the more compact, single-core model; X10 adds a second selectable heating core for up to 10 kW total output.
Does AUTO save fuel?
AUTO adjusts heat output toward the set temperature. Running at a lower output uses less diesel than running continuously at maximum output, but actual consumption depends on the weather, insulation, selected temperature and heating demand. Stop & Go is a separate stop-and-restart function. We do not promise a fixed percentage of fuel savings.
Is the fuel tank 10 L or 20 L?
X5 includes a 2.6-gallon (10 L) tank. X10 includes a 5.3-gallon (20 L) tank. Some connection photos show a different tank size; they illustrate the fittings, not the included tank capacity.
Can I run it from a portable power station?
Use a power source that meets the heater's voltage and current requirements. X5 uses 10–40 W while running and briefly up to 130 W at startup. Battery runtime depends on usable capacity, operating mode, weather and conversion losses. Keep power connected through the complete cooldown cycle.
Do I need an adapter for a U.S. outlet?
No plug adapter is needed. The supplied power unit has a native U.S. plug. Follow the rating on the supplied unit; the heater itself operates on 12V DC.
Can the heater stay inside the tent?
No. Keep the heater body, fuel tank and exhaust outdoors. Install the supply/return air duct as directed. CO sensors are additional protection, not a substitute for ventilation, safe exhaust placement and a separate working CO alarm.
How long will one tank last?
Runtime depends on output and conditions. Published consumption is approximately 0.04–0.15 U.S. gal/hr (150–550 mL/hr). Use the actual fuel level and conditions when planning your trip; do not rely on a single all-night runtime promise.
