How we tested
First, we conducted a visual inspection of the water heater system. We looked for any visible leaks around fittings, the tank, and water lines. For gas-powered units, we made sure the ventilation was clear and the propane valve was open. For electric models, we verified that the power connection was secure and the switch was functional.
Next, we filled the water heater tank. We connected the camper to a fresh water source or used the onboard water pump, then opened a hot water faucet to let air escape and confirm that the tank was filling. We waited until a steady flow of water came out, indicating the tank was full.
Once the tank was full, we turned on the camper water heater. If it was electric, we simply switched it on and let it heat for about 20–30 minutes. If it ran on propane, we turned on the gas, triggered the ignition (either manually or via an electric switch), and listened for the clicking sound of the igniter. We also checked the sight glass (if available) to confirm the burner had lit.
After 20 – 30 minutes, we checked the water temperature at the faucet using a thermometer. The expected range was around 120–140°F (49–60°C). We made sure the water was heating evenly and consistently.
During heating, we also monitored key safety features: the pressure relief valve should release a small amount of water (which is normal), and the thermostat should automatically shut off the heater once the desired temperature is reached. For gas models, we watched to see if the burner would cycle on and off properly during extended use.
Finally, we performed maintenance checks. We flushed the tank to remove sediment, inspected the anode rod (if the tank had one), and confirmed that any winterizing or bypass valves were set correctly.
FAQ
Are tankless water heaters good for campers?
Each option comes with its own pros and cons, but tankless RV water heaters are generally favored by many RV enthusiasts for their compact design and extended lifespan.
How does a water heater work in a camper?
Camper water heaters operate similarly to the gas water heaters commonly found in homes. A spark lights a small flame inside a heating tube, which in turn warms the water stored in the tank. Most RV hot water tanks typically have a capacity between 6 and 10 gallons.
How do I reset a camper water heater?
To reset a camper water heater, first turn off the power and gas supply. Open the exterior access panel and locate the reset button – usually red and found on the thermostat or ECO switch. Press the button firmly until it clicks. Then, restore power and gas, and turn the heater back on. If it doesn’t work, check the fuse, breaker, or thermostat.
