How RV Water Heaters Work
Understanding how RV water heaters work is crucial for RV owners to make informed decisions about their usage. RV water heaters are designed to provide hot water for daily use, just like water heaters in traditional homes. However, there are some key differences that make RV water heaters unique.
Types of RV Water Heaters
There are two main types of RV water heaters: tankless and tank-style. Tankless water heaters, also known as on-demand water heaters, heat water only when it is needed. This means that hot water is instantly available, but the flow rate may be limited.
Tank-style water heaters, on the other hand, store and heat a specific amount of water in a tank, providing a continuous supply of hot water. The choice between these two types depends on the specific needs and preferences of the RV owner.
Ignition and Heating
RV water heaters can be ignited using different methods, such as electronic ignition or a pilot light. Electronic ignition systems are more common in modern RV water heaters. They automatically ignite the propane or gas burner when hot water is needed.
Pilot light systems, on the other hand, require manual ignition and are less common nowadays. Once ignited, the burner heats the water in the tank or passes it through a heat exchanger in the case of tankless models.
Thermostat and Sensors
RV water heaters are equipped with thermostats and sensors to regulate and maintain the desired water temperature. The thermostat monitors the water temperature and signals the burner to turn on or off as needed. This ensures that the water remains at a consistent temperature for optimal comfort.
Additionally, some RV water heaters have safety features, such as high-temperature limit switches, to prevent overheating and potential damage.
It is important to note that leaving an RV water heater on all the time may not be necessary or practical. The decision to leave it on or turn it off depends on factors such as the frequency of use, energy efficiency, and personal preference.
It is recommended to consult the RV manufacturer’s guidelines and consider the specific needs of your RV lifestyle.

Safety Concerns of Leaving It On
Leaving your RV water heater on all the time may seem convenient, but it is important to consider the safety implications. There are several potential risks associated with keeping your water heater constantly running.
Risk of Explosion
One of the main safety concerns of leaving your RV water heater on is the risk of explosion. Water heaters are designed with safety features to prevent excessive pressure build-up, but malfunctions can still occur.
If the pressure relief valve fails or the temperature control malfunctions, the pressure inside the tank can increase to dangerous levels. This can lead to an explosion that can cause serious damage to your RV and put your safety at risk.
Carbon Monoxide Poisoning
Another significant risk of leaving your water heater on all the time is the potential for carbon monoxide poisoning. RV water heaters are typically fueled by propane gas, which produces carbon monoxide as a byproduct of combustion.
If the exhaust system becomes blocked or damaged, carbon monoxide can accumulate inside the RV. Carbon monoxide is a colorless and odorless gas that can be deadly when inhaled in high concentrations. It is important to have working carbon monoxide detectors in your RV and to ensure proper ventilation when using the water heater.
Overheating and Fires
Leaving your RV water heater on constantly can also increase the risk of overheating and fires. If the thermostat malfunctions or the water heater is not properly maintained, it can continue to heat the water beyond safe temperature limits.
This can lead to overheating, which can cause damage to the tank and surrounding components. In extreme cases, it can even result in a fire. It is crucial to regularly inspect and maintain your water heater to ensure it is functioning properly and to prevent any potential fire hazards.
It is important to note that the safety concerns mentioned above are not meant to discourage the use of RV water heaters. Rather, they highlight the importance of using them responsibly and taking necessary precautions.
Turning off the water heater when it is not in use or when you are away from your RV can help mitigate these risks and ensure the safety of you and your fellow travelers.
Efficiency and Cost Considerations
Propane Usage
One of the primary factors to consider when deciding whether to leave your RV water heater on all the time is the propane usage. RV water heaters typically run on propane, and keeping it on continuously can quickly deplete your propane supply.
This can be especially problematic if you are camping in a remote location where propane refills may not be readily available. It is recommended to conserve propane by only turning on the water heater when it is needed.
Electricity Load
If your RV water heater has an electric option, leaving it on all the time can also have an impact on your electricity load. Running the water heater continuously can put a strain on your RV’s electrical system, potentially leading to blown fuses or tripped breakers.
Additionally, keeping the water heater on when it is not needed can result in unnecessary energy consumption, leading to higher electricity costs. It is advisable to only turn on the water heater when you actually need hot water.
Wear and Tear
Leaving your RV water heater on all the time can also contribute to increased wear and tear on the appliance. The continuous operation can put additional stress on the various components of the water heater, potentially leading to faster deterioration and a shorter lifespan.
By only using the water heater when necessary, you can help extend its longevity and reduce the need for costly repairs or replacements.
Ultimately, the decision of whether to leave your RV water heater on all the time depends on your specific needs and circumstances. If you frequently require hot water throughout the day, it may be more convenient to keep it on.
However, if you are looking to conserve resources and minimize costs, it is recommended to turn the water heater on only when needed.
Maintenance Best Practices
Proper maintenance is essential to keep your RV water heater in good working condition and extend its lifespan. Here are some best practices to follow:
Draining and Flushing
Regularly draining and flushing your RV water heater is crucial to remove sediment and mineral buildup that can affect its efficiency. This should be done at least once a year or more frequently if you notice a decrease in hot water performance.
To do this, turn off the water heater and let it cool down. Then, locate the drain valve and attach a hose to it. Open the valve to allow the water to drain out completely. Once drained, close the valve and flush the tank with fresh water to remove any remaining debris.
Anode Rod Inspection
The anode rod is a sacrificial component that protects the interior of your RV water heater tank from corrosion. Over time, the anode rod will deteriorate and need to be replaced. Regularly inspecting the anode rod can help you determine its condition.
To do this, locate the anode rod access port on the top of the water heater and unscrew it. If the anode rod is heavily corroded or less than 50% of its original size, it’s time to replace it. Anode rods are inexpensive and easy to install, so it’s worth checking this component regularly to avoid costly tank replacements.
