Turning on the hot water heater in your travel trailer is generally a straightforward process, involving preparing the tank, selecting your power source (propane or electric), and igniting the burner or element. This guide provides a comprehensive breakdown of the process, ensuring you enjoy hot showers and clean dishes on your next adventure.
Understanding Your RV Hot Water Heater
Before diving into the specifics, it’s crucial to understand the fundamentals of your RV hot water heater. Most travel trailers utilize a tank-style heater, typically holding between 6 and 10 gallons of water. These heaters operate on either propane or electric power, offering flexibility depending on campsite hookups. Some models even feature both propane and electric options for faster heating. Understanding your specific model is the first step in ensuring proper operation.
Identifying Your Hot Water Heater
Begin by locating your hot water heater. It’s usually situated behind an access panel on the exterior of your travel trailer, often near the rear. The panel will have a vent for propane exhaust. Inside, you’ll find the tank, burner (for propane models), and potentially an electric heating element. Consult your trailer’s owner’s manual for specific locations and diagrams.
Step-by-Step Guide to Turning on Your Hot Water Heater
Follow these steps carefully to ensure a safe and efficient process:
-
Ensure the Tank is Full: This is the most crucial step. Running a propane hot water heater without water in the tank will almost certainly result in a burned-out heating element, a costly repair. To fill the tank, connect your RV to a water source (city water hookup or the RV’s freshwater tank). Open a hot water faucet inside the trailer and let it run until the water flows continuously and consistently. This indicates the tank is full and the air has been purged.
-
Select Your Power Source: Determine whether you want to use propane, electricity, or both. Using propane is generally faster, but electricity is more convenient at campsites with full hookups.
-
Propane Operation:
- Turn on the propane tanks at the trailer.
- Purge the propane lines by lighting a stove burner inside the trailer until a consistent flame is established. This ensures propane is flowing to the appliances.
- Locate the switch for the hot water heater, typically inside the trailer, near the monitor panel. It will often be labeled “Water Heater.” Flip the switch to the “ON” position.
- The hot water heater will attempt to ignite the propane burner. You may hear a clicking sound as the igniter sparks. If it doesn’t ignite on the first try, turn the switch off and then back on. Repeat this process a couple of times. If it still fails, check the FAQs below for troubleshooting tips.
-
Electric Operation:
- Ensure your RV is connected to a suitable power source (30-amp or 50-amp service is recommended).
- Locate the electric heating element switch. This is often located inside the trailer, near the monitor panel, often labeled simply “Water Heater,” and sometimes accompanied by a separate breaker in the electrical panel. Flip the switch to the “ON” position. Some models have a separate switch located directly on the hot water heater itself, accessible through the exterior access panel. Be sure to check both locations.
-
Wait for the Water to Heat: It can take 15-30 minutes for the water to heat up, depending on the ambient temperature and the size of the tank.
-
Test the Water: Carefully open a hot water faucet to check the water temperature. Start slowly to avoid being scalded by excessively hot water.
Frequently Asked Questions (FAQs)
Here are some common questions about RV hot water heaters:
FAQ 1: What happens if I run the hot water heater without water?
Running a propane hot water heater without water will severely damage the heating element, often causing it to burn out completely. Electric heaters can also be damaged, although some have high-temperature cutoffs to prevent immediate damage. Always ensure the tank is full before activating the heater.
FAQ 2: How do I drain my RV hot water heater?
To drain your hot water heater, turn off the heater and allow the water to cool completely. Locate the drain plug, typically at the bottom of the tank behind the exterior access panel. Remove the plug and allow the water to drain completely. Some models also have an anode rod, which should be inspected and replaced periodically.
FAQ 3: What is an anode rod, and why is it important?
The anode rod is a sacrificial metal rod inside the hot water heater tank. It attracts corrosive elements in the water, protecting the tank itself from corrosion. Regularly inspect and replace the anode rod to prolong the life of your hot water heater.
FAQ 4: My hot water heater isn’t igniting on propane. What could be the problem?
Several factors could prevent ignition, including:
- Low propane levels: Ensure your propane tanks are full.
- Air in the propane lines: Purge the lines by lighting a stove burner.
- Faulty igniter: The igniter may need to be replaced.
- Dirty burner: Clean the burner with a wire brush.
- Blocked flue: Ensure the flue is free from obstructions.
FAQ 5: How do I winterize my RV hot water heater?
Winterizing your hot water heater is essential to prevent damage from freezing temperatures. Drain the tank completely, bypass the heater if your RV has a bypass valve, and add RV antifreeze to the lines.
FAQ 6: Can I leave the hot water heater on all the time?
Leaving the hot water heater on constantly is generally not recommended. It consumes energy unnecessarily, and the constant cycling can wear down the heating element. Turn it on only when you need hot water.
FAQ 7: My hot water smells bad. What can I do?
A sulfurous or rotten egg smell often indicates bacteria growth in the tank. Flush the tank with a mixture of bleach and water (follow the instructions in your RV owner’s manual) and then thoroughly rinse it.
FAQ 8: How often should I flush my RV hot water heater?
You should flush your RV hot water heater at least once a year, or more frequently if you notice sediment or debris in the water.
FAQ 9: What size hot water heater do I need for my RV?
The appropriate size depends on your usage and the number of people traveling with you. A 6-gallon tank is usually sufficient for a couple, while a 10-gallon tank is better for larger families.
FAQ 10: Can I use a portable hot water heater instead of a built-in one?
Yes, portable hot water heaters are available and can be a good option for smaller trailers or those who want to supplement their existing hot water system.
FAQ 11: What is a hot water heater bypass valve?
A bypass valve allows you to isolate the hot water heater from the rest of the plumbing system, which is useful for winterizing or when you don’t need hot water.
FAQ 12: Where can I find replacement parts for my RV hot water heater?
Replacement parts are readily available at RV dealerships, camping supply stores, and online retailers. Be sure to have your heater’s make and model number handy when ordering parts.
Conclusion
Turning on your travel trailer hot water heater is a relatively simple task with a few key considerations. By following these steps and understanding the FAQs, you can ensure a consistent supply of hot water for all your camping needs. Always prioritize safety by ensuring the tank is full before activating the heater and regularly maintaining your system to prevent problems down the road. Enjoy your hot showers!
