When the temperature drops and you're miles from civilization, your van heater becomes your lifeline. Here's everything we've learned about keeping warm on the road.
We've all been there. You're parked at a stunning mountain overlook, the stars are incredible, and then the temperature plummets to 20°F. Suddenly, that Instagram-worthy adventure becomes a test of survival. That's when you realize just how crucial a reliable vanlife heating system really is. As we explore in our vanlife myths and reality guide, heating challenges are one of the biggest gaps between Instagram vanlife and the real experience.
In the Grover community we've seen every heating scenario imaginable. From diesel heaters that won't start at 6,000 feet elevation to propane systems that work perfectly until you need them most. We've collected troubleshooting wisdom from manufacturers, van builders, and real vanlifers who've learned the hard way.
Here's what makes this guide different: our knowledge base is enriched by our direct partnership with Rixens, a leader in van heating solutions. This means you're getting troubleshooting and maintenance advice straight from the source, trusted by van builders and manufacturers. When we share a fix, it's not just community wisdom (though that's valuable too). It's information from the horse's mouth.
Types of Van Heating Systems: Finding Your Perfect Match
Let's start with the basics. Not all van heaters are created equal, and what works perfectly for weekend warriors might leave full-time vanlifers shivering. Here's what we've learned about the main types:
Diesel Heaters: The Vanlife Gold Standard
Diesel heater for vans systems like Eberspacher, Webasto, and Rixens units are the most popular choice in our community, and for good reason. They're efficient, powerful, and run off your vehicle's fuel supply.
Popular Brands We Support:
- Eberspacher Diesel and Gas
- Webasto Gas Heaters
- Rixens heating solutions (our direct partner)
- Propex
- TrumaElwell Timberline
- And more
Why Vanlifers Love Them:
- Extremely fuel efficient
- Can heat both air and water (hydronic systems)
- Work independently of your house battery
- Reliable in extreme cold
The Reality Check: These systems can be finicky. Our Grover knowledge base contains detailed troubleshooting guides because, let's be honest, they will act up at some point. But when properly maintained, they're incredibly reliable.
Propane Heaters: Simple and Effective
Propane systems like the Webasto STC series offer simplicity that many vanlifers appreciate. According to our knowledge base, if a Webasto propane heater fails to start after 2 attempts, you should check power (11V to 13V), fuel supply, and ensure air inlet/outlet grilles aren't restricted.
Electric Heating: For the Solar-Powered
Heat pumps and electric heaters work great if you have substantial solar and battery capacity. We see these most often in high-end builds with lithium battery banks.
Common Van Heater Problems and Expert Fixes
This is where our partnership with Rixens and access to manufacturer documentation really shines. We've compiled the most common issues and their solutions:
"Why Won't My Van Heater Turn On?"
This is the #1 question in our Grover community. Here's the systematic approach our experts recommend:
Step 1: Basic Power Check
- Verify fuses (typically 25A for combustion, 10A for fan)
- Check battery voltage (needs 11-13V minimum)
- Inspect all electrical connections
Step 2: Fuel System Inspection
- Confirm fuel in tank (seems obvious, but it happens!)
- Check for fuel line restrictions or air bubbles
- Verify fuel quality (no gelling in cold weather)
Step 3: Airflow Verification
- Clear combustion air inlet and exhaust outlet
- Remove any obstructions from fresh air vents
- Check for ice buildup in cold conditions
Grover's quarterly maintenance checklist ensures your heater runs optimally when you need it most
The "H1 No Fuel" Error Code Solution
Our Eberspacher troubleshooting guide reveals a common issue: the H1 error often appears when diesel fuel has drained back down the line after sitting unused. The fix? Press the center button and restart the unit up to 5 times to push air bubbles through the system.
Hard Reset Procedure for Persistent Issues
From our knowledge bases. Pull both the heater combustion fuse (25A) and heater fan fuse (10A), leave them out for one minute, then reinstall. This performs a hard reset that solves many mysterious issues.
Expert Maintenance Tips from Our Manufacturing Partners
Thanks to our direct relationships with heating manufacturers, we can share maintenance wisdom that prevents problems before they start:
Monthly Operation Protocol
Even if you're not using your van, run your heater for at least 20 minutes monthly. This keeps parts from seizing and lubricates the fuel pump. We've seen too many heaters fail after sitting unused for months.
Annual Maintenance Checklist
- Replace fuel filter (or more often if needed)
- Clean combustion air inlet and exhaust outlet
- Inspect all electrical connections
- Check fuel lines for wear or restrictions
- Test operation before your first cold-weather trip
Altitude Considerations
Our knowledge base includes specific guidance for high-altitude operation. Many heaters need adjustment above 5,000 feet, and some systems require different settings for optimal performance.
Grover provides specific altitude adjustment guidance for optimal heater performance at elevation
Vanlife Winter Tips: Staying Warm When It Matters Most
How do I winterize my van? This question spikes every October in our community. Here's our comprehensive approach, building on the essential safety protocols that every vanlifer should know:
Insulation is Your First Line of Defense
No heater can overcome poor insulation. We've learned that proper insulation reduces heating costs and makes your system more effective. Understanding these winter heating expenses is crucial for budgeting your cold-weather adventures.
Backup Heating Solutions
Our most experienced vanlifers always have a backup plan:
- Buddy propane heaters for emergencies
- Electric blankets for sleeping
- Hot water bottles (old school but effective)
- Proper sleeping bags rated for expected temperatures
Condensation Management
Heating creates moisture, and moisture creates problems. Proper ventilation is crucial even when it's freezing outside.

What should I do if my diesel heater shows an "H1 No Fuel" error?
The H1 error often indicates air bubbles in the fuel line, especially after the heater has been unused for a while. Press the center button and restart the unit up to 5 times to push air through the system. If the error persists, check fuel levels and inspect fuel lines for restrictions or leaks.
Can I install a van heater myself?
While possible, heater installation involves fuel lines, electrical connections, and exhaust systems that require specific expertise. Improper installation can be dangerous and void warranties. We recommend professional installation, especially for diesel systems. If you choose DIY, follow manufacturer instructions exactly and have the work inspected.
What are the signs that my van heater needs professional service?
Key warning signs include unusual noises, frequent error codes, reduced heating efficiency, visible exhaust smoke, fuel odors inside the van, or the heater shutting down unexpectedly. If you notice any of these symptoms, contact a certified technician immediately for safety reasons.
How do I prepare my van heating system for long-term storage?
Before storing your van, run the heater for 20 minutes to circulate fluids, drain water lines if equipped with hydronic heating, disconnect the battery or use a maintainer, clean air intakes and exhausts, and consider professional servicing if storing for more than 6 months.
What should I do if my heater works intermittently?
Intermittent operation often indicates loose electrical connections, fuel supply issues, or sensor problems. Check all electrical connections first, verify consistent fuel pressure, clean sensors and air intakes, and monitor for error codes. Document when failures occur to help technicians diagnose patterns.
Are Chinese diesel heaters reliable for full-time vanlife?
Chinese diesel heaters can work for full-time use but require more attention to installation quality, regular maintenance, and spare parts availability. They lack the support network of major brands like Webasto or Eberspacher. Consider your mechanical skills and access to parts when deciding.
