Best Hot Water Heater for RVs Buying Guide
Tankless vs. Tank-Style Systems
Tankless water heaters provide an endless supply of hot water by heating it on demand, which is ideal for RVs where space is at a premium. These units are generally lighter and more energy-efficient because they do not need to store and maintain the temperature of several gallons of water.
Traditional tank-style heaters offer a familiar experience with a reserve of hot water ready for immediate use. While they are heavier and occupy more storage space, they can be more forgiving in areas with very low water pressure or when you need to draw water from multiple sources simultaneously.
Understanding Power and Fuel Requirements
Most RV water heaters rely on propane to generate heat, even if they use 12V DC or 120V AC for ignition and control systems. Ensure your RV's propane system is rated to handle the BTU output of your chosen heater to avoid performance issues during operation.
Hybrid models provide the best of both worlds by allowing you to switch between propane and electric heating. This is particularly useful when you are connected to shore power at a campsite, as it allows you to conserve your propane supply for other essential appliances.
Installation and Fitment Considerations
Before purchasing, measure your existing water heater cutout precisely. Many modern tankless units are designed to fit standard 15-inch by 15-inch openings, but variations in depth and plumbing connections can require minor modifications to your RV's cabinetry.
Check the location of your water and gas inlets. While most units use standard 1/2-inch NPT connections, the orientation of these ports can differ between brands. Having flexible hoses on hand can simplify the connection process and reduce stress on the plumbing lines.
Performance at High Altitudes
If you frequently travel to mountainous regions, look for heaters specifically rated for high-altitude operation. Standard burners may struggle to ignite or maintain a stable flame in thin air, leading to inconsistent water temperatures or frequent error codes.
Units equipped with brushless DC fans and advanced combustion technology are better at adjusting the air-to-fuel ratio. This ensures reliable performance even at elevations exceeding 8,000 to 9,000 feet, where oxygen levels are significantly lower.
Safety and Maintenance Features
Safety should be a top priority for any gas-powered appliance inside an RV. Look for CSA-certified models that include automatic flame-failure shut-off, overheat protection, and dry-burn sensors to prevent damage to the unit and ensure passenger safety.
Maintenance-friendly features like built-in freeze protection are essential if you travel in colder climates. These systems automatically engage to prevent water lines from bursting, saving you from costly repairs and ensuring your system remains operational throughout the winter season.
Frequently Asked Questions
Can I install an RV tankless water heater myself?
Yes, many RV owners choose to perform their own installation if they are comfortable working with basic plumbing and propane connections. Always follow the manufacturer's instructions, use proper sealing techniques, and test for leaks before putting the system into regular use.
Do I need a special water pump for a tankless heater?
Most tankless heaters require a minimum water flow rate to trigger the burner. If your RV's existing water pump is weak, you may experience fluctuating temperatures. Upgrading to a constant-pressure water pump can help ensure a steady flow and consistent heat.
How do I know if a new heater will fit my current cutout?
Measure the height, width, and depth of your current water heater opening. Compare these dimensions to the specifications provided by the manufacturer. Many tankless models include universal door panels that can cover a range of standard cutout sizes.
Are tankless heaters more energy-efficient than tank heaters?
Generally, yes. Tankless heaters only consume propane when you are actively using hot water, whereas tank heaters must periodically fire up to maintain the temperature of the water stored in the tank, even when you are not using it.
What should I do if my water heater shows an error code?
Most modern RV water heaters have a digital control panel that displays specific error codes. Consult your user manual to identify the issue, which is often related to low water pressure, a blocked exhaust, or a gas supply problem.
Conclusion: Our Top Pick
Our top pick is Orbek RV Tankless Water Heater. Choosing the right water heater for your RV depends on your specific travel habits and the infrastructure of your vehicle. Tankless models offer the convenience of endless hot water and space savings, while hybrid units provide the flexibility to switch between power sources depending on your campsite amenities.
By carefully measuring your existing cutout and considering your typical travel elevations, you can select a system that provides reliable comfort for years to come. Prioritize safety certifications and features like freeze protection to ensure your investment stands up to the rigors of the road.
