My Personal Experience with Van Water Heaters
Three years ago, I started my van life journey with a basic portable water heater for camping that I'd connect outside the van. While it worked, the inconvenience of setting it up every time I needed hot water became frustrating, especially during winter camping in the Rockies.
The Learning Curve
My first permanent installation was a disaster. I chose a unit based solely on price and ended up with constant ignition failures in high altitude conditions. After dealing with cold showers for a week in Yellowstone, I learned the importance of researching altitude ratings and cold weather performance.
Finding the Right Balance
My current setup uses the Camplux 5L system, which I've now operated for over 18 months across 30 states and varying elevations from sea level to 10,000+ feet. The key insight I gained is that reliability trumps features every time. A simple, well-built unit will serve you better than a feature-rich system that fails when you need it most.
Seasonal Considerations
During winter months in Montana and Colorado, I learned the importance of proper insulation and freeze protection. I now recommend installing a small 12V heating pad under the unit and insulating all exposed water lines. This simple modification prevented numerous freeze-related failures that plague many vanlifers.
The investment in a quality water heater pays dividends in comfort and reliability. After helping dozens of fellow vanlifers with their installations and troubleshooting, I can confidently say that the models I've recommended above represent the best options currently available for different needs and budgets.

Frequently Asked Questions
What size water heater do I need for my campervan?
The size depends on your usage patterns and occupancy. For solo travelers or couples, a 5-6 gallon tank or 1.32 GPM tankless unit typically suffices. Families or those who enjoy long showers should consider 10+ gallon tanks or higher flow rate tankless units (2.5+ GPM). Consider your fresh water tank capacity as well - there's no point in having a large water heater if your fresh water supply is limited. I recommend calculating your typical daily hot water usage and sizing accordingly, keeping in mind that tankless systems provide unlimited supply as long as you have fuel and water.
Can I install a water heater myself, or do I need a professional?
While many aspects of water heater installation can be DIY projects, propane connections should always be inspected by certified technicians for safety reasons. I've successfully completed numerous installations myself, but I always have the gas connections professionally certified. Electric-only units are generally safer for DIY installation, though you should still ensure proper electrical connections and follow local codes. The complexity also varies significantly based on your van's existing plumbing and electrical systems. If you're uncomfortable with any aspect of the installation, hiring a professional is worth the investment for peace of mind and safety.
How much propane does a campervan water heater use?
Propane consumption varies significantly based on unit size, usage patterns, and outside temperature. A typical 5L tankless unit consumes approximately 0.5-0.7 gallons of propane per week for moderate use (two people, daily showers). Larger units with higher BTU ratings will consume proportionally more. Tank systems use propane for initial heating and maintaining temperature, while tankless units only consume fuel when actively heating water. In my experience, a 20-pound propane tank typically lasts 3-4 weeks with moderate hot water usage in temperate conditions, but this can drop to 2 weeks in very cold weather due to increased heating demands.
What maintenance is required for campervan water heaters?
Regular maintenance is crucial for longevity and safety. For tankless units, I recommend annual descaling using manufacturer-approved solutions, especially if you frequently use hard water sources. Check and clean air intake screens monthly, and inspect propane connections quarterly using leak detection solution. Tank systems require more intensive maintenance including annual anode rod inspection and replacement if necessary, tank flushing to remove sediment buildup, and periodic pressure relief valve testing. Regardless of system type, always inspect exhaust vents for obstructions and ensure proper clearances are maintained. Keep spare parts like ignition electrodes and thermocouples on hand for field repairs during extended trips.
Do campervan water heaters work at high altitude?
Altitude performance varies significantly between models and can be a critical factor if you plan to spend time in mountainous regions. Standard propane appliances typically experience reduced efficiency above 2000 feet due to decreased air density affecting combustion. However, many modern units like the AMZCHEF model I recommend are specifically rated for high altitude operation up to 9800+ feet. I've personally tested various units throughout the Rocky Mountains and can confirm that properly rated units maintain consistent performance even above 10,000 feet. If high altitude travel is in your plans, ensure your chosen unit specifically lists altitude ratings and consider models with automatic altitude compensation features.
How do I winterize my campervan water heater?
Proper winterization prevents costly freeze damage and ensures reliable operation in cold conditions. For systems that will be unused during freezing weather, completely drain all water lines and the heater itself, then blow out remaining water with compressed air. Add RV antifreeze to trap seals and moving parts as specified by the manufacturer. For year-round operation in freezing conditions, insulate all exposed water lines and consider installing tank heaters or heating pads on vulnerable components. I also recommend installing a bypass valve system that allows you to isolate the water heater during winterization while maintaining operation of other plumbing systems. Always test the system thoroughly when returning to service after winter storage.
Conclusion
Choosing the right campervan water heater is one of the most important decisions you'll make for your van life setup. After testing dozens of units and helping countless vanlifers upgrade their systems, I can confidently say that the five models I've recommended represent the best options currently available for different needs and budgets.
The RV Tankless Water Heater 55,000 BTU remains my top overall recommendation for its reliability and performance, while the budget-conscious Camplux 5L offers exceptional value for smaller setups. Remember that the best water heater is the one that matches your specific needs, travel style, and van configuration.
Key takeaways from my experience: prioritize reliability over features, invest in proper installation and safety certifications, and don't underestimate the importance of regular maintenance. Whether you're just starting your van life journey or upgrading an existing system, any of these recommended units will provide years of reliable hot water for your adventures.
