For me, adding a new component to my setup is only worthwhile if it works effectively and accomplishes the task at hand.

Nothing is more frustrating than a hot water heater that takes forever to heat water to an unsatisfactory temperature.
This Girard heater performs well, producing 42,000 BTUs, and features a quiet engine that runs on 12V electricity at less than 3 amps—perfect for RV electrical systems.
I really enjoy the inbuilt microprocessor function since it monitors the flow rate, the temperature of the hot water, and the temperature of the incoming cold water to help keep everything working properly.
This means that I am no longer subject to abrupt spurts of chilly or scorching water, as discussed in more detail in the video below:
I appreciate that the heater has a digital control panel that allows me to choose the temperature I want, ranging from 95° to 124°, and that if there are any problems with the heater, there is an easy-to-use error code system.

The expensive price is the only drawback for me. For a small portion of the price of this Girard water heater, there are other electric tankless RV water heaters available.

This heater is an excellent choice for RVs to consider because of its easy installation, low cost, and lightweight construction.
Why Select a Tankless Electric Water Heater?
There are several justifications for selecting an electric tankless water heater.
Maybe you want to reduce the amount of power you use overall, or maybe you want extra hot water for you and your RV visitors.
Maybe it’s time to replace your old water heater, and you want to install a more effective one.
Or maybe you want a water heater that is a little smaller than your current one.
Whatever your motivations, installing an electric tankless water heater in your RV has a lot of advantages.
The biggest benefit is that anytime you switch on the hot water at your sink or shower head, you will always have hot water available.
You will ultimately save money on energy with an electric tankless water heater, which is another benefit.
When you’re not using it, conventional electric water heaters keep a few gallons of water warm all day.
Tankless electric water heaters heat water just when it is needed, saving you from wasting energy on heating large amounts of water that won’t be used.
For many RV owners, this may be a very significant benefit.
Tankless electric water heaters are much less costly than they ever were.
One that is expressly designed for RVs is likely to be priced around the same as a more conventional tank water heater.
Regarding an electric tankless water heater, are you still on the fence? Continue reading to find out more about some of the benefits and drawbacks of these heaters, as well as how to switch from the typical propane tank water heater found in an RV to an electric tankless heater.
Electric Tankless Water Heaters: Pros and Cons
Here are some advantages and disadvantages of this new kind of equipment in case you aren’t convinced by the previously mentioned advantages of an electric tankless water heater.
Pros: Hot Water Anytime
The biggest benefit of a tankless water heater, in case you hadn’t figured it, is that hot water is always accessible.
A 4-6 gallon hot water heater is insufficient for the majority of single travelers and couples (much alone huge families!) in today’s RVs, therefore this is a need.
You may get hot water as long as you have water in your freshwater tank or are connected to municipal water, which is always flowing through the pipes in your RV.
You may be surprised to learn that you won’t always have access to hot water if you’re new to RVing.
The majority of full-time RVers that I am aware of miss lengthy, hot showers the most.
You won’t have to worry about skipping out on those residential house showers ever again with an electric tankless water heater!
Cons: High Initial Cost
The high upfront cost of an electric tankless water heater is a possible drawback.
These appliances are not always inexpensive, particularly if you are on a strict spending plan or if your current hot water heater is still functional.
When the time is perfect, it’s always wonderful to consider updating your appliances, but the upfront expense of a tankless water heater can cause you to put off this update longer than you intended to.
You may not feel the need to acquire an electric tankless alternative just yet if you already have a perfectly enough water heater installed.
Should you want expert assistance with this, you should also take the cost of installation into account.
Similar to tank heaters beneath your RV, installing an electric tankless water heater may be challenging.
If you are unsure of your ability to complete a DIY project, you may want to hire a professional to assist with installing this sensitive electrical system.
The initial cost will only increase as a result, so this is something to keep in mind.
Pros: It’s Inexpensive (If You Have Shore Power Connectivity)
Given that most conventional RV water heaters use gas, if your RV has regular shore power access, adding an electric tankless water heater might end up costing you relatively less in the long run.
For instance, if you often stay in RV parks or campsites, electricity is always provided for free there.
You always have access to free hot water if you have an electric water heater.
Efficiency is another consideration in the design of these devices.
An electric tankless water heater is designed to heat your water as effectively as possible, even if your RV is connected to your home’s electrical system.
An electric tankless water heater can be your best choice if you’re seeking for a long-term energy-saving alternative.
Because they only heat water when necessary, these devices use less power overall.
Cons: You May Not Have Enough Amps.
Despite using less power overall than conventional electric water heaters, electric tankless water heaters will consume more electricity than you anticipate, particularly if you’re switching from a conventional propane tank water heater.
If you don’t already have a budget for your new electric tankless water heater and your RV has access to 30 amps of power, you may want to take some time to do some math.
It’s possible that you don’t have enough amps to power your new water heater.
This is why I advise getting an RV multimeter as soon as you start RVing.
To better plan how many amps you have available for any new appliances, you may use this tool to evaluate how many amps the rest of your appliances are using.
Pros: Convenient and Simple to Use
It’s simple to set and forget with an electric tankless hot water heater.
They often have remote controls and simple-to-read LED display displays that indicate the temperature and give you the freedom to modify as you choose.
If you want to wash laundry in your RV or even give a little kid a bath or shower, you can easily adjust the hot water temperature.
For many RVers, the ability to easily modify the temperature may be a godsend.
Con: Installation Could Be Challenging
An electric tankless water heater might be challenging to install on your own, as I previously indicated when discussing installation and where to locate expert assistance.
This may be particularly true if you’re switching from a conventional gas water heater to a tankless electric one.
You’ll need to understand how to rewire various components of your RV, cover or otherwise remove your current propane lines, and more.
Many RVers are not very enthusiastic about this specific appliance installation since you will probably be using both electricity and gas.
Even if it can wind up costing more than you anticipated, take into account expert assistance while installing them.
How to Switch to a Tankless Electric Water Heater
Are you certain that you want to go from a propane tank to an electric tankless water heater? Great! Before you make this very significant shift, there are a few additional things you should think about.
#1. Take Into Account Your Electricity Use
You should think about your power use before switching to an electric tankless water heater, as I have previously indicated.
Some appliances consume less amps than others, and when it comes to RVing, the less amps used, the better.
Nevertheless, the majority of electric tankless water heaters only consume energy when you need hot water, so you probably won’t need to plan for it when you aren’t taking a shower or doing the dishes.
Unless you require a lot of hot water at once, two air conditioners, a microwave, and a hair dryer, you probably won’t need to worry about your power use if you have a 50 amp RV.
#2. Think About Your Propane Use
When it comes to your old water heater, you are probably used to budgeting for your gas consumption.
However, because you’re switching to an electric tankless water heater, you probably won’t have to worry about propane any more.
It may come as a nice surprise to many of you, but having an electric tankless water heater gives you extra propane for cooking and even heating your RV.
By investing in an RV propane barbecue, you can put that gas to good use.
#3. Get Rid of That Old Water Heater
If you want to install an electric tankless water heater, you probably won’t want to leave your old water heater in place inside your RV.
Simply taking up space, the old water heater may even be necessary to make room for the new one.
However, taking anything out of an RV might be a hassle.
If you are new with DIY RVing, you should have the right equipment, check that every fuel connection is disconnected or turned off, and even contact a buddy for assistance.
It is far simpler to remove an old water heater than to install a new one.
Later, however, more on it!
#4. Examine The Wiring In Your RV.
The wiring for your new electric tankless water heater has to be carefully inspected, just as it would be if you were installing a new RV tank monitoring system.
To securely power your new device, your electric tankless water heater will require dependable and long-lasting wiring.
If you are unfamiliar to this procedure, you might think about hiring an electrician or RV repair expert to guide you.
Once again, confirm that you are not using shore power and that your RV’s battery is completely unplugged.
While examining possibly naked wires, you don’t want to take the chance of hurting yourself.
#5. Install Your New Tankless Electric Water Heater.
It may be harder than you think to install your new electric tankless water heater.
It would be helpful to have a buddy who is knowledgeable about this kind of stuff, or you could just pay an RV repair expert to do the task for you.
Read up on the work in advance if you want to install your new electric tankless water heater yourself.
Always carefully read the instruction booklet that came with your new equipment, and take your time to ensure the work is completed correctly.
#6. Keep Your Water Pressure in Mind
What is a fact regarding electric tankless water heaters that you may not be aware of? It’s the truth that different water pressures might be difficult for the majority of tankless water heater solutions.
When traveling in an RV, water pressure is always a factor to take into account.
You may connect a variety of pressure regulators to your hoses to prevent damage to your pipes from city water and other public water connections.
With your new water heater, you should also think about how crucial water pressure is.
Many electric tankless water heaters may be quite problematic for RVers since they often won’t run if the pressure isn’t at a specified level.
All tankless water heaters, however, need a certain amount of water pressure that your RV pipes can withstand.
Although you may have to take off your pressure regulator, it is often a comfort to know that you will have hot water.
#7. The Question of Boondocking
If you want to go boondocking regularly, electric tankless water heaters may not be the best choice.
Boondocking, commonly referred to as dry camping, is when you set up camp without any connections or access to shore power.
For the majority of contemporary RVs, boondocking is popular and relatively feasible, but an electric tankless water heater may struggle in these conditions.
This is due to the likelihood that all of your utilities, including electricity, are more expensive.
However, there are several approaches of overcoming this.
Make sure you choose an RV battery designed specifically for boondocking.
This can run your tankless water heater for the length of your vacation and will help to allay many of your electricity-related worries.
You should also take into account other solar-powered devices, such as RV freezers.
However, it will make your rig even more boondock ready.
Installing solar may not be a relatively inexpensive solution to your electric tankless water heater power sources.
Tankless Electric Water Heater Alternatives
A 240-volt connect up is often required in place of a 120 V hook up for many electric tankless water heaters.
This basically implies that since these gadgets use so much power, the majority of RVs can’t manage them.
This idea can make you prefer a different option.
Check out these electric tankless water heater options if you aren’t quite convinced on them or are concerned about how much power they will need to provide a consistent supply of hot water for you.
#1. Tankless Propane Water Heaters
Another choice for tankless water heaters in RVs is propane, which many RVers seem to prefer over other fuel types.
This may be due to the fact that many RV owners enjoy boondocking and propane functions best in off-grid settings.
Since most RV water heaters are fueled by propane, propane tankless water heaters are also preferable replacements for your current water heater.
Even though you should always use caution while installing a new water heater, doing so could be less difficult than switching to an electric water heater.
Since the total cost is comparable, many RVers use propane tankless water heaters with few to no problems over time.
If you use a lot of energy and it appears like there isn’t much available amperage, this is absolutely something to think about.
Some of the top propane tankless water heaters on the market right now are already on our list.
Check them out today by clicking here!
#2. Heaters for Electric Water (With Tanks)
There are various electric water heaters with tanks that you might consider buying for your RV if you like the concept of an electric water heater but are dissatisfied with any of the tankless choices.
In my antique vehicle, I switched from a gas water heater that was never functional to a brand-new Bosch electric water heater.
Although this product’s capacity is just four gallons, it fits in my trailer without any trouble.
Although electric water heaters may use a significant amount of power, installing them is often simpler and they are typically less expensive than tankless solutions.
If you’re on a tight budget and feel handy, you can think about skipping the additional storage and getting an electric water heater with a tank instead.
#3. Solar Sprinkling
You can think about making your own solar shower if you only want to go camping during the warm summer months.
The more adventurous camper or the RVer on a tight budget may find these DIY choices to be quite helpful.
A solar-heated bag and an attachable shower handle or head are used in these showers.
Even if you’re using them outside, you may construct or buy ones that are pressured to offer you a more authentic shower experience.
However, because of their limited water capacity, you may not want to take a shower in your swimming suit outside of your RV.
Those of you who wish to utilize your RV and have hot water in the cooler months cannot use this option.
With our list of the best products in mind, finding an electric tankless water heater for your RV will be much simpler.
When you go out on your journey, you can rest easy knowing that you have enough hot water for the whole family.
