Having all of the conveniences of home at your fingertips when camping in an RV is one of the most enjoyable aspects of the experience – with hot water being one such convenience. In our last article, we described how to ignite the pilotlight of an RV water heater. Now, let’s examine how to ignite the pilotlight of an electric water heater. Step-by-step instructions on how to turn on an electric water heater in an RV are provided in this fast tutorial. In addition, you’ll discover a few crucial strategies to avoid causing damage to your water heater in the process.

How to Turn On an Electric RV Water Heater

Making an electric water heater work in an RV is a straightforward process, with the most of the complexity stemming from where to locate the on/off switch and whether you have a gas or electric (or both) water heater, which we’ll discuss further below. Notably, do not attempt to switch on an electric RV water heater if there isn’t any water in the water heater tank. The electric heater element will be completely destroyed if this is done. For step-by-step directions on how to fill an RV water heater, see our tutorial on how to fill an RV water heater.

As an illustration, we’ll utilize the well-known Suburban SW6DE.

  1. Before starting, check to see that there is water in the hot water tank. Take note of your hot water heater access panel, which is usually located on the outside of your RV, and remove it
  2. On the panel, look for the on/off switch for the RV water heater. Typically, it is found on the bottom left-hand side of the screen (as shown in the image above). To turn on the light, turn the switch to the on position.

Is it a good idea to leave my RV’s water heater running all of the time? Please refer to your owner’s handbook for the specific step-by-step procedure for turning on your water heater, since each brand and model may be somewhat different from the others. If you have misplaced your owner’s handbook or need to contact the manufacturer, the following are links to some of the most common RV water heater manufacturers, which include Forrest River, Keystone, Jayco, and other prominent brands:

  • Suburban, Dometic (previously Atwood), FogattiTanklessWater Heaters, and more manufacturers.

RV Electric Water Heater Troubleshooting Guide

Starting with the following items to check if your RV electric water heater is not functioning correctly after you have turned it on:

  1. Check to see that the circuit breaker in the RV has not been tripped. Check for 120-volt alternating current (AC) at the on/off switch. In order to reset the unit, press the reset button on the control panel, which is normally situated near the on/off water heater switch
  2. And If the heater continues to malfunction after the efforts described above, turn off the power and inspect all wire connections (consult to your owner’s handbook for a wiring diagram if necessary). Finally, using a voltage meter, check that the heating element is still operational. If an element is found to be faulty, it must be replaced.

If you are still experiencing problems, you should consult with a trained RV mechanic.


Electric, propane, and electric/gas combination water heaters are the three types of RV water heaters available. Electric water heaters, as the name implies, use electricity to heat water. Heat your water using an electric/gas combination water heater by using either one or both of the fuel sources, or both gas and electricity at the same time.

How Do I Know if My RV Water Heater Is Gas or Electric?

You may determine if your RV water heater is gas or electric by reviewing the owner’s handbook for the precise brand and type of heater that you have purchased. Using the model number, you may determine if it is a gas, electric, or hybrid water heater even if you do not have your owner’s handbook (which you can find on the access panel). Once you’ve obtained that number, you may use the table below to determine what sort of heater you possess.

How to Use Your RV Water Heater

If you compare RV camping to conventional camping, it’s a step up in terms of luxury. RV campers not only have the luxury of sleeping in a comfy bed every night, but they also have the convenience of taking hot showers in their very own bathroom anytime they choose. Before anybody can take use of those hot showers, they must first get familiar with the operation of their RV water heater. Fortunately, this isn’t too difficult to accomplish, and as long as you keep up with routine maintenance, your RV’s water heater should continue to provide reliable service for many years.

RV Electric Water Heater vs RV Propane Water Heater

RV water heaters with tanks are available in three different configurations: electric water heaters, propane water heaters, and combination heaters. An electric water heater, as the name implies, warms water by utilizing electricity to do so. This works rather well and is especially useful for campers who have power included in their camping fees and who want to preserve gas. That being said, unless you have an inverter, you will be unable to use a water heater that is exclusively powered by electricity when boondocking.

The ideal RV water heater choice for folks who prefer dry camping and want to save money on energy is a propane RV water heater.

Using a Traditional RV Hot Water Heater

It’s time to go on to the next step, which is how to start hot water in an RV. Consider the following scenario: you’re traveling in your RV and you’re ready to utilize the water heater. Consider the following points if you’re dealing with a typical water heater—the sort that has a tank—when installing a water heater. First and foremost, you’ll want to make certain that your hot water tank is filled with water. To accomplish this, first check to see that any bypass valves that may cut off the water supply to your tank are open rather than closed.

Open a hot tap and let the water to flow for a few seconds to cool the water.

Following that, you’ll

Caring for an RV Hot Water Tank

In any case, after you’ve figured out how to correctly operate your RV water heater tank, you’ll want to make certain that it stays in good working order. An RV water heater should be serviced every 6 to 12 months, depending on its age. Fortunately, this is a straightforward process. Start by shutting off the heater and allowing plenty of time for the water inside to cool down. Removing the drain stopper or anode rod and letting the tank to drain entirely will ensure that any silt and debris will be removed from the tank once it has reached room temperature.

If your tank is equipped with an anode rod rather than a simple plastic plug, now is a good time to replace the anode rod. This helps to keep the accumulation in your tank to a minimum. Anode rods for sale may be obtained on Amazon and at Camping World.

Choosing an RV Tankless Water Heater

Not a fan of having to wait for the water to heat up every time you want to take a shower or wash dishes? No problem! A consistent stream of hot water is what you’re looking for. It’s possible that a tankless water heater for an RV is the best option for you. This RV modification is becoming increasingly popular, and after you’ve experienced the convenience of having hot water available on demand, you’ll understand why. Are you looking for the finest tankless water heater for your RV? TheCamplux 5L Portable Propane Tankless Water Heater, on the other hand, is quite popular among RV owners.

Carry out your own study to determine which one will best meet your requirements, and then learn to appreciate lengthy, hot showers.

RVing 101 Guide: Water Heaters

If your RV is equipped with plumbing, there is a good probability that you have a water heater. Compared to a typical house or apartment water heater, the RV water heater will be smaller, but it will operate in essentially the same way. You can use hot water for anything from showering and washing your hands to cleaning the dishes since it warms water as it is used. All RV owners should be familiar with the fundamentals of their RV water heater since it comes in handy whether you’re cooking, cleaning, showering, or doing anything else while on the road.

RV Water Heaters 101

The first thing you should know about RV water heaters is that they are fueled by propane, not electricity. Unless you’ve spent a lot of money on a high-end vehicle, A propane-fueled water heater and other equipment will be required in your motorhome, motorcoach, or luxury recreational vehicle (RV). A six-gallon tank is standard for most RVs, with some units using as much as a ten-gallon tank depending on the size of the vehicle. Some water heaters are exclusively compatible with gas, while others are compatible with both propane and electricity.

A pilot light is used in the majority of recreational vehicle water heaters.

If you have the latter installed in your RV, you will turn on the water heater by pressing a button on the interior of the RV or trailer.

Before Your RV Water Heater’s First Use

Before turning on your RV water heater for the first time, ensure sure it’s fully stocked with enough water to last the whole trip. For instructions on how to fill and maintain the water level in the device, refer to the manufacturer’s instructions once again. The following steps can be applied to RV and trailer water heaters in the vast majority of cases:

  • Check the bypass valve on the water heater. Allow the water to flow into the primary tank by opening the valve. To begin pumping water, connect your RV to a local water outlet and use the onboard pump to start the process. Start by turning on the hot water faucet. Water will begin to flow through your lines and into the heating tank
  • This is a normal occurrence. Fill it all the way up to the fill line, and your water heater will be ready to use

Advice from the experts: Once again, consult your manufacturer’s instructions on how to fill the specific water heater for your RV or trailer before using it for the very first time. During the off-season, be sure to empty your water heater.

This is especially important during the winter and while placing your RV or trailer in storage for the winter. If you fail to do so, you may wind up with mold and mildew in your home, as well as the need to repair your water heater sooner rather than later.

RV Water Heater Maintenance

When you examine, clean, and care for them on and off the road, they will last longer and require less maintenance than the majority of the components in your RV or trailer. It is no different with your water heater.

  • Depending on the sort of water heater you have, you may need to clean it more frequently than once a year. Make sure your water heater is included in your normal RV maintenance plan, and anytime you take your rig to the shop, ask the mechanic to check it to make sure it’s in good operating condition. When winterizing your RV or trailer, you should always drain all of the water from the water heater and check that all of the lines are clear. Follow the same procedure for all of the lines in your RV or trailer to guarantee that your water heater is ready for the winter or a lengthy period of time when it will be parked and not in use.

Advice from the pros: If you’re not confident in your ability to manage your RV water heater, consider bringing it to your RV dealer or a repair shop and having them handle it. Make a point of doing this if you detect any problems, or at least once a year before you begin traveling for the year. You should now be aware of all you need to do to maintain your RV water heater and guarantee that it continues to perform both on and off the road. Thank you for informing us about this!

How to Use an RV Water Heater

Documentation Download Documentation Download Documentation An RV water heater allows you to have warm water even when you are camping in the middle of nowhere. Even better, RV water heaters are simple to install and use, so you’ll be able to enjoy hot water in no time at all!

  1. 1 Connect a hose to the water intake valve on the RV. Located on the outside of your RV, the intake valve should be easy to locate. It is typically equipped with a blue handle. Using a hose, attach it to the spigot and tighten it down so that water does not flow out
  • Bring new water into your RV using a clean hose to avoid contaminating the water
  • Otherwise, the water may get contaminated. Installing a tankless water heater is as simple as connecting a hose to the intake and connecting it to a water supply. You are not required to fill a tank. It is possible that your RV has specific instructions for filling the tank, therefore always check with the owner’s handbook first
  • Secondly, connect the other end of the hose to a water supply. Depending on where you are filling up, this may be a garden hose connection if you are filling up at home, or a pump if you are filling up while camping. Whichever method you choose, attach the other end of the hose to this source and tighten it down to avoid any leaks.
  • For those staying at a campsite, there are generally designated water sources where people may fill their campers with water. If you are unable to locate it, inquire as to its whereabouts. You will not be able to fill your tank from a lake or stream unless you have a pump mechanism. In order for the water to flow into the tank, it must be under pressure.
  • Advertisement
  • s3 Turn on the water supply valve. Turning the valve counterclockwise will allow it to be opened. Water should begin to flow into the tank at this point.
  • On some recreational vehicles, you may also need to open the intake valve. This might be the source of the problem if water is not flowing into the tank.
  • 4 Fill the water tank all the way to the top of the fill line. Keep the water running and let the tank to full. When it reaches its maximum capacity, switch off the water and disconnect the hose from the intake and source sockets.
  • Some recreational vehicles are equipped with a fill meter located near the intake valve. Other than that, check the tank itself to verify whether the water level reaches the fill line
  • Else Maintain your focus on the fact that water is heavy, and that your car will consume a lot of petrol if you load it to its maximum capacity. If you’re intending on traveling, you might want to fill the tank only halfway and then fill it the rest of the way when you get at your location.
  • 5Close the bypass valve for the water heater. When the bypass valve is activated, water is diverted away from the heater tank and into your cold water faucet. Close the bypass valve to ensure that water is sent into the water heater instead
  • 6 One of your sinks should have a hot water tap turned on. This circulates water through the water heater and out the faucet at the same time. If water is flowing, then the system is operating properly
  • Otherwise, it is not.
  • If there is no water flowing out of the faucet, this indicates that the hot tank is depleted of its water supply. Double-check to ensure that the bypass valve is properly closed.
  • 7 Allow the water to run until no more air can be seen coming out of the faucet. When you initially turn on the water, it may splutter a little. This is normal. This is okay since it just indicates that air is being expelled from the system. Continue to run the faucet until the water flows out smoothly and without any air bubbles, at which point you may turn on the water heater.
  • There should never be any air left in the water heater system when it is turned on. This might result in damage to the tank.
  1. 1 Fill your propane tank with water. Your RV’s tank should be located on the exterior of the vehicle. To open the valve and allow propane to flow, turn the knob counterclockwise.
  • It is best not to open the propane tank until just before you are ready to turn on the water heating system. When you’re not using propane, it’s quite dangerous to leave it running.
  • 2 If your RV has an automatic start, turn on the “Water Heater” switch located within the vehicle. Electronic auto starters are quite simple to operate. Simply press the “Water Heater” button to ignite the pilot light and begin heating the water
  • This is all it takes.
  • A little indicator light is normally located next to this switch, which indicates whether or not the heater is turned on. If your heater would not ignite, it is possible that the propane tank is not open. If you don’t do this, you may have an issue with your switch. Taking the RV in for maintenance is a good idea.
  • 3 Manual starts can be initiated by locating the control panel on the outside of your RV. Manual light water heaters need the completion of a few more tasks. A latch or screws are often used to secure the panel in place. The pilot light and ignition controls are accessible by opening it up.
  • Always read and follow the instructions provided by your RV’s manufacturer before accessing the control panel.
  • 4 To begin manually, turn the knob on the control panel to the “Pilot” position. It is necessary to crank the control knob in order to pick the desired setting. Turn it so that it reads “Pilot” on it so that you may start the pilot light.
  • Propane will not begin to flow until you turn the knob all the way down. Don’t press until you’re ready to fire the pilot light
  • Else, you may burn yourself.
  • 5 Light the pilot light with a long barbeque lighter to ensure proper ventilation. To release propane, turn the control knob all the way down. Afterwards, bring the lighter up close to the pilot light and light it to ignite the gas.
  • Keep the knob down for a few seconds to allow the system to warm up
  • This is only necessary for manual starters. An automated starter will start the pilot light without the need for any further actions.
  • 6 Change the setting of the control knob from “Pilot” to “On.” After the pilot light has been turned on, turn on the main heater. Turn the control knob all the way to the “On” position. This ignites the primary heater and causes the water in the tank to begin to heat up.
  • When you’re lighting the heater, keep your face away from the control panel on the wall. When it ignites, there may be a brief flash of light. After you turn on the heater, it will take around 30 minutes for the water in the tank to reach the desired temperature. Close the propane valve when you’re through with the water heater. When you aren’t using it, it is quite risky to leave it running.
  1. 1 Connect the RV’s power cord to a power outlet. Connect the power line from your RV to a power source and plug it in. The majority of campgrounds provide RVs with power hookups like this.
  • Depending on where you are camping, there may be an additional price for utilizing the electricity.
  • 2 Turn on the water heater’s power switch by pressing it. The power switch for the water heater is normally located within the cabin and appears similar to a standard light switch. To begin heating the water, turn the knob to the “On” position.
  • As a general rule, the switch is labeled “Water Heater,” thus it should be straightforward to locate
  • It is possible that an earlier model’s On switch is located on the water heater itself rather than within the cabin.
  • 3 Allow 60-90 minutes for the water to reach the desired temperature. Warming the water with electric heaters takes a little longer than with gas heaters. It will take around 60-90 minutes, depending on the size of the tank, so be patient before utilizing the hot water
  • RV water heaters are typically equipped with a light that indicates when they are operational. If the light does not come on, it is possible that the bulb has burned out or that the water heater is not functioning properly. Take the RV to a repair shop so that it may be serviced
  • 4 When you’re through using the hot water, turn the switch off. As soon as the water is hot, turn off the water heater to preserve power. Wait until you’re ready to use the heater again before turning it back on.
  • You should leave the power source plugged in if you are still using energy in your RV, for example, to power lights or the kitchen. If you don’t want to use it, you may disconnect it when the water is hot.

RVs are equipped with two different types of hot water heating systems. The most popular type of water tank is one that is heated by propane gas. Tankless systems are commonly featured in newer, higher-end recreational vehicles. Unlike tank-based systems, tankless systems deliver continuous hot water, and their capacity is limited only by the quantity of accessible water in the RV. Prior to embarking on a camping vacation, it is recommended that the RV hot water heater be thoroughly inspected.

Items you will need

  • RV with a water heater
  • Propane tanks that are completely full
  • RV battery that has been fully charged
  • Access to electrical power from the coast
  • Hose, RV owner’s manual, and other supplies

Using an RV Water Heater

Connect the RV to a water source in the city or at the park. Check to see that the hot water heater has been turned off. Check to check that the water heater tank in the RV is completely filled. Activate a hot water faucet and let the water to flow until there is no sputtering any more. If there is no water left in the tank, replenish the hot water heater tank before continuing. Turn on the propane tanks and double-check that the water heater is properly connected to the LP system before continuing.

Turn on the water heater in your RV.

Older versions may include a manual pilot light or starter, which is not recommended.

  • Never switch on the hot water heater if the tank is completely depleted. The tank will heat up fast and inflict irreparable damage to the unit
  • Do not drive the RV while the pilot light to the water heater is burning, as this causes a fire danger
  • Do not leave the RV unattended while the pilot light to the water heater is lit
  • RV water heaters are typically powered by propane, although certain models are also capable of running on 120-volt alternating current. In the vast majority of circumstances, propane is less expensive to use than electricity for heating. You should take use of the 120-volt AC option if your campsite fees offer unrestricted electricity use. If the pilot light will not remain lit, there may be debris in or around the propane tank that is plugging the gas outlet. To clear any obstruction from the gas outlet aperture, insert a tiny wooden toothpick into the entrance and gently poke it out.

Even while certain specifics differ based on the individual brand and model of water heater you have, many of the fundamental fundamentals are the same for practically all RV water heaters.

RV Hot Water Heater Basics

Most recreational vehicle water heaters will feature a 6-gallon or 10-gallon tank, however tankless heaters have grown increasingly popular in recent years.

Tankless Hot Water Heaters

Tankless water heaters are also referred to as “on demand” systems since they provide hot water on demand. These units can be powered by propane or electricity, which powers a heat exchanger in the device, which heats the water as it flows through it. Tankless means that there is no water in the unit other than the minimal amount of water that is stored in the internal pipework; this is why it is referred to as such. There were no items found. There were no items found.

On Demand Operation

Every time you turn on your hot water faucet, you are creating an artificial demand for hot water. Once the machine detects the presence of water flowing through the inner pipe, the heating elements immediately turn on and begin to warm the water in the tank. Water heats up to a temperature that is acceptable for washing and bathing in the brief amount of time it takes to travel through the sequence of internal piping. When the hot water tap is turned off at the faucet, the tankless heater detects the interruption in the flow of hot water and shuts off the heating element to minimize energy consumption.

Pros and Cons of Going Tankless

To be sure, tankless hot water heaters have the potential to deliver a continuous flow of hot water for showering, cleaning, and anything else you need until the power or gas supply is interrupted. This is a significant benefit over a standard tank-style water heater, which must be prepared before use and is typically limited to producing only warm water during periods of high demand. In addition to energy economy, which is important in an RV since saving gasoline and electricity is critical while traveling off the grid, there are several other significant advantages.

Another advantage of tankless hot water heaters is their physical size; as compared to traditional hot water heaters, they tend to be considerably more compact machines. The most significant disadvantage of this type of hot water tank is the

Hot Water Tank Heaters

Typical RV hot water tanks feature a 6-10 gallon tank or reservoir to retain water while the tank is being heated, similar to what is usually seen in residential hot water tanks. Mini-tank water heaters, on the other hand, have just lately entered the market, offering a “point-of-use” alternative that may be installed and connected directly to a sink or shower head. Check out the most recent offers.

Hot Water Tank Operation

Regardless of whether or not hot water is being utilized, the control unit will maintain a certain temperature in the tank as long as electricity and fuel are available to it. The temperature of the water in the tank is detected by a sensor that comes into contact with it. When the sensor detects a dip in water temperature, it sends a signal to the control module, which then activates the heating element in the water. There are several reasons for this, including the fact that the water has been lying around and has cooled down over time, or the fact that hot water is being used, which is sucking the water out of the tank and cold water is entering the tank in its stead.


Benefits of a Hot Water Tank

Traditional hot water tanks are less expensive than tankless alternatives, and they’re also rather reliable when it comes to performance.

Electric Water Heaters

If your RV is equipped with an electric water heater, the heating element will cycle on and off as needed to maintain the water temperature, so you won’t have to worry about turning it off while the RV is not in use. Electric water heaters provide the advantage of preserving your gas while also more efficiently maintaining the correct temperature of your water at all times. Unless your water heater has the capability of switching back to propane when you are not connected to shore power, you will be unable to boondock without using your generator for hot water when you are not connected to shore power.

  • INSTALLATION WITHOUT A CENTRAL CONTROL: For independent installation or in-line with a big hot water supply, the 36-37″ chord connects into a 120 volt outlet.

Propane Water Heaters

Unless you’ve invested much in a high-end recreational vehicle, your hot water heater is almost certainly powered by propane. It requires the same procedure as all other propane appliances: the lighting of a pilot flame. Some RVs need you to manually ignite the engine with a lighter once you’ve parked and leveled the vehicle, but most contemporary RVs are equipped with direct spark ignition. To use direct spark ignition, all you have to do is switch on the water heater. As a result, if there is a requirement for water to be heated, the thermostat will detect this and the control circuit board will open the gas valve while simultaneously utilizing the igniter to produce a spark in the front of the gas burner tube.

The most significant advantage of

Filling your Water Heater

When you turn on your water heater for the first time, or when you turn it on for the first time after winterizing, you’ll need to fill the tank with water before turning it on. The suggested water levels for your individual model will be listed in the owner’s handbook, but you may alternatively take the safe route and fill the tank entirely. If your water tank is equipped with a bypass or drain, make sure to close it before you begin filling it. Filling your hot water tank may be accomplished by utilizing water from your fresh water tank and the RV water pump, as described above.

It is also possible to do so with the water pressure provided by the city water that is linked to your water hook up. All of your plumbing connections have been tightened to the maximum extent possible.

How to Operate Your Hot Water Heater

Even though your hot water heater is powered by gas, it requires electrical electricity to operate. The electrical system of your home requires the activation of a number of different components in order for it to work properly.

Electrical Panel

If your hot water heater is electric, there should be a fuse or circuit breaker to supply power to it. This will power the electronic control board, the igniter, and the element, if your water heater is powered by electricity. It will be necessary for the water heater to function properly that the CB be in the “on” position or that the fuse be fitted and in functioning order.

On/Off Switch

The on/off switch is the next level of control, and it will be positioned on a main control panel or close to the device in question. Turn on the tank by flipping the switch to the on position; an indicator light will normally glow to indicate that the tank is operational.

Propane Supply

To ensure that your propane water heater is operational, make certain that the propane supply is switched on at the main tank. A shut off valve near the hot water tank may also be present and must be changed to the open position in order to function properly. It’s likely that you’ll hear the igniter clicking and, in some cases, even the flame blazing once you flip the on/off switch on. Additionally, the indication light should be lighted. If you’re using electric or propane to power your tank, it will typically take between 20 and 35 minutes for your tank to heat up depending on its size, the temperature of the water within the tank, and other factors.

Temperature Adjustment

Most RV water heaters do not come with the ability to modify the thermal limit switch; instead, you must learn to be a master of the mixing bowl in order to get the temperature you wish. Having said that, you have the option of replacing the thermal limit switch with an adjustable thermostat if you so choose to. It’s not a terrible thing to think about because you can save a lot of propane by setting the maximum temperature closer to tepid rather than lava hot with an adjustable thermostat, and replacing out the parts isn’t a difficult DIY job to complete.

Conserving Water and Energy

Because your RV’s water heater is likely to be considerably smaller than the one in your home, paying close attention to how and when you use your hot water will help you avoid running out of hot water when you need it the most. For example, if you use a lot of hot water to clean the dishes and then immediately turn around and hop in the shower, you won’t be able to enjoy that shower for as long as you would want. That one, believe me, is something I’ve learnt the hard way.

How to Drain Your RV Hot Water Heater

Just like you would do when checking the anode rod, you’ll want to switch off your water heater and then open the pressure release valve before attempting to empty it completely. This will prevent you from being shocked or burned throughout the process, which are both things I do not advocate you experience. By opening the pressure release valve at the top of the tank, you can ensure that you are not firing high-pressure water at yourself when you remove the plug.

Once the tank has been equalized, you may remove the plug. The water will flow out, and it is also a good opportunity to clean out the tank during this process. As an alternative to utilizing the flush wand as described, you may alternatively turn on the city water again for a few minutes.

Basic Hot Water Heater Maintenance

Make sure to turn off the electricity to your hot water heater before beginning any maintenance work, and then empty out any hot water that has accumulated in the tank using the procedure indicated above to remove any remaining hot water from the tank. As a general rule, propane water heaters will require a bit more maintenance than electric water heaters. This is mostly due to the fact that you’ll want to wipe out the burner tube on a yearly basis to ensure that there isn’t any debris obstructing the flow of gas.

Checking The Anode

Every season, you should examine the quality of your anode rod in all of your tanks, but especially at the beginning and conclusion of the season. The anode is a metal rod that is intended to corrode instead of the inner walls of your tank’s interior. Prior to performing any maintenance on the tank, cut off the electricity to the tank and allow the water within to cool for an hour or two.

  • • LONG-LASTING QUALITY: Constructed of high-quality magnesium that is particularly designed to be used and collected for a long period of time
  • • PROLONG WATER HEATER LIFE: The anode rod is a critical component of any water heating system that contributes to the overall longevity of the water heater. PROTECT HEATERS FROM CORROSION: This anode rod for RV and outdoor water heaters functions as an effective filter for water that is kept in the heater.

The first step is to release the pressure that has built up in your hot water storage tank. The pressure release valve on the outside of the water heater may be opened, or a hot water faucet in your RV can be opened with the pump switched off and the outer hose unplugged from the outside connection can be opened. To remove the anode rod, you’ll most likely need a 1-1/16-inch socket and a wrench; it’ll be placed towards the bottom of the tank and accessible through the vent door on the outside of your RV.

Prepare to get your hands a bit wet.

Replacing The Heating Element

It’s probable that the heating element in your electric water tank will need to be changed at some time during your RVing experience. This procedure is analogous to that of changing the anode. After removing the electricity from the appliance, relieve the pressure in the tank and drain the tank following the procedure outlined above. Once the water has been drained from the element, unscrew the terminal screws and detach the wires from the element, making note of their locations. Take out the old element and replace it with a new one by using a wrench.

Replacing The Electrode

The electrode, often known as the igniter, is responsible for producing the spark that ignites the propane. If your water heater makes use of a two-prong electrode, it may only require a thorough cleaning. In order for the spark to leap between prongs and ignite the fuel, the electrode must be free of dirt. When using a single prong electrode, the same thing might happen, however the spark leaps to a neighboring metal surface rather than to a second prong. To remove the electrode, unhook the wiring from the device and unscrew the screw that holds it in place on the device.

It is possible to clean the electrode tip with steel wool or fine grit sandpaper and then reinstall it to test whether it still performs properly. If this is the case, replace the electrode with a new one by doing the reverse procedure.

Closing Thoughts

After all, you purchased your RV in order to bring some of the comforts of home with you on the road, and learning how to properly fill and drain your water heater as well as how to operate and maintain your water heater can help to make that experience even more enjoyable.

RV Water Heater Basics

Camping in a tent is great fun, but RV camping allows you to bring the luxuries of home with you into the most remote parts of the wilderness. One such convenience is the availability of an adequate supply of hot water. RV water heaters make it feasible to do so even when you’re in the middle of nowhere and not connected to the electrical grid. Since their inception, camper water heaters have performed in a remarkably consistent manner, owing to their straightforward design, which has endured the test of time.

Knowing how they work and how to repair them can keep you traveling in luxury and style in your rental RV or your own RV for a long time.

RV Water Heater Types

Listed below are the four different types of RV water heaters you’ll encounter.

Propane (LP) Only RV Water Heater

As the name implies, this is the original form of RV water heater, and it will operate in practically any environment as long as you have propane gas in your tanks and a little amount of 12v power in your RV batteries. Unlike a gas-fired water heater in your house, the operation of these camper water heaters is similar: A spark is formed, which ignites a little flame in a heating tube, which heats the water. The flame then warms the water in a tank, which is subsequently used for cooking. The hot water tanks in most recreational vehicles are between 6 and 10 gallons in capacity.

In order to operate the switches that automatically cut off the flame once the water is hot, gas-fired RV water heaters require a little amount of 12v electricity from your RV’s batteries. Important safety features are also provided by these switches, such as

Gas + Electric RV Water Heater

Several newer RVs are fitted with hybrid RV water heaters, which may operate on either gas or 120v electricity, or a combination of the two. While their upfront prices are greater than those of gas-only RV water heaters, these hybrid heaters might be an excellent choice if you frequently stay at campsites that have electricity available. In this instance, your water heater will simply make use of the energy that has been provided to keep the water hot in your camper. It is also possible to use both the gas and electric heating components simultaneously when using these hybrid RV water heaters.

Electric RV water heaters have two major drawbacks: they take far longer to heat up than gas-fired water heaters, and they consume a large amount of power while doing so.

Tankless RV Water Heater

If you are looking for a water heater for a camper, tankless RV water heaters have just emerged as the new child on the block. The great majority of recreational vehicle water warmers feature tanks that are between 6 and 10 gallons in capacity. Given that most home water heaters have a capacity of more than 40 gallons, it is possible to run out of hot water when taking a long shower in an RV with a tanked water heater. Using a tankless water heater, you may avoid the problem of running out of water by heating the water as it passes through your pipes.

Compared to tank-style RV water heaters, tankless RV water heaters are more costly, more sensitive to low water pressure, and more difficult to maintain than their tank-style counterparts.

MotorAid RV Water Heater

Because it is a supplementary feature on many RVs, MotorAid is just half of an option on the list. By circulating the engine heat around the water heater tank, this device helps to recycle engine heat. As a consequence, when you get at your location, you will have hot water since your engine’s usual working temperature has heated it. Once you’ve parked your vehicle, you’ll have to rely on propane gas or power to keep your water warm.

Which type of RV water heater should you choose?

The type of RV water heater you choose will be determined by your specific circumstances. If you want to park in an area where power is available, the gas+electric hybrid RV water heater might be an excellent choice for your needs. An RV water heater that runs only on gas is a dependable and economical alternative if you plan to camp in an area without power hookups. A tankless RV water heater is ideal for individuals who live full-time in their camper and/or have a family who will be taking a lot of hot showers.

Tips for Operating an RV Water Heater

Here are five things to keep in mind if you own or operate an RV water heater in your vehicle.

  1. Your RV water heater will most likely be manufactured by Atwood or Suburban. These RV water heaters are quite dependable, and replacement parts for them are easily obtained from any RV parts store. It is recommended that you empty your water heater in the winter if you opt to install a tankless water heater (Girard is the primary maker of these). RV water heaters with tanks are all provided with a plug that allows the tank to be drained if necessary. In order to winterize your camper, you must drain the water heater from the vehicle. This will prevent the water in the tank from freezing and causing damage
  2. Moreover, an anode rod will assist your camper’s hot water heater last for a longer period of time. An anode rod is a simple and inexpensive device that will prevent corrosion and buildup in the inside of your hot water heater. Using an RV water filter will help you save money.

Water heaters in travel trailers are among the simplest and most dependable equipment on the globe, and they are also among the most affordable.

You will enjoy hot, pure water for years to come if you only perform the basic maintenance described above.

Basic RV Water Heating Trouble Shooting

The following items may be of assistance if you are experiencing difficulties with your RV water heater operation:

  • The problem is that your water heater will not ignite. Make sure that you have 12v power running to the water heater before proceeding any further. It’s probable that your circuit board or ignitor is the source of the problem if you have electricity. Both of these components may be purchased at a local RV parts retailer. Problem: Despite the fact that you can hear the ignitor clicking, the heater is still not igniting. It’s possible that you’re having trouble getting propane gas to your RV water heater. During this time, you should consult with a trained specialist who will examine your LP gas system
  • Troubleshooting: Your RV water heater ignites, but it appears to be burning inefficiently or not heating up rapidly. Turn off your water heater and look for blockages in the heating tube to determine the cause of the problem. Remove any dirt or filth that you may have discovered in there.

When it comes to troubleshooting, YouTube and RV forums might be your best friends. Chances are that you are not the only person to have this condition, no matter how serious it may seem. Other RVers are always willing to lend a hand in figuring out the source of your RV problems! Here’s a nice video from The Great Outdoor RV that includes some helpful advice for troubleshooting your water heater.
