Electric Tankless Water Heaters for RV Buyer’s Guide
What is an Electric Tankless Water Heater?
A tankless water heater often called a demand-only water heater, heats tap water directly as needed by users. It is different from a traditional storage-tank water heater because it does not store hot water; instead, it heats water as you need it. This means that you can save energy and money by not having to keep hot water in a storage tank that you may not use for hours or even days at a time.
Electric tankless water heaters are becoming more popular in recent years, particularly in RVs where space is limited. They are also growing in popularity as people look for ways to reduce their energy consumption and save money on their utility bills. 
What is the Purpose of a Tankless Water Heater?
The purpose of a tankless water heater is to provide hot water on demand without the need for a storage tank. These units are small and compact, which makes them ideal for RVs where space is limited. They are also energy-efficient because they only heat water when you need it, rather than keeping hot water in a storage tank that may not be used for hours or even days at a time.
Tankless water heaters can provide an unending supply of hot water, making them ideal for big families or individuals who enjoy long showers! They are also great for people who want to save money on their energy bills.
What Are the Various Types of Tankless Water Heaters?
There are two primary types of water heaters: point-of-use (POU) and whole-house (WHO). POU units are small and can be installed under a sink or in a cabinet. WHO units are larger and must be installed outside the home.
POU units are less expensive than WHO units, but they also have some disadvantages. For example, POUs can only supply hot water to one tap at a time, so if your RV has multiple showers, you will have to purchase multiple POUs. WHO units are more expensive, but they can provide hot water to multiple fixtures simultaneously. 
The decision of which type or model to buy is not as easy. There are pros and cons for each one, so it’s important that you think about your needs before making this big purchase! If all you need in the future will be hot water at certain fixtures then consider buying POU (point-of use) units instead; if on the other hand there’ll always come a time where more than 2 people could use their showers simultaneously then go ahead with WHO unit models.
What to Consider When Purchasing the Right Electric Tankless Water Heater
How Much Room Do You Have?
One of the first considerations you need to make is just how much space you have available. These heaters come in a variety of sizes, so you must take measurements before making your purchase. You also need to think about where you will be mounting the heater. Some models are designed for indoor installation, while others are made for outdoor use.
What is the efficiency of the heater?
The efficiency of an electric tankless water heater is typically between 80-98%.
The efficiency of an electric tankless water heater is often measured by the temperature rise. The difference between incoming cold and outgoing hot waters, for example if we take a set where both are at 40 degrees Fahrenheit but one was raised by 100° F then it would have more than double its effectiveness! 
The Flow Rate of the Tankless Water Heater
Higher flow rates mean you can use your tankless heater to heat more water in less time, which is beneficial if there are multiple people living at one address who need their own individual temperature set points.
A low-flow model may work well for single individuals or small families since they won’t be using the same amount of hot fluids as someone with larger needs would – say an apartment complex full up with dozens of units fighting over those few GPM slots!
For example, if you have a large RV with multiple bathrooms, you will likely need a higher flow rate than someone who has a smaller RV with only one bathroom.
To figure out how many gallons of hot water a heater can produce in an hour, just multiply the GPM by 60. For example if you have 12 gauge pm and your home needs about 8-10 hrs worth or heating throughout each day then this means that there will be about 600 – 720 total servings every 24 hours which could make for some fairly warm showers!
Heaters that produce a high amount of GPMs tend to be more efficient. For example, an electric tankless water heater could lose up to 20% efficiency when you increase its flow rate from 2 Gallons Per Minute (GPM) and 3 GPM respectively but only 10%.
Your Water Usage
The first thing you need to think about is your average water usage. This will help you decide which size & flow rate is right for you. To do this, simply look at the number of people using your RV and how often you’ll be using hot water each day.
If you have a large family or plan on spending extended periods in your RV, then you’ll want to choose a model with a higher flow rate. Conversely, if you’re single or have a smaller family, then you can get away with a lower flow rate model.
The Generation Capacity of the Heater
One more you need to consider is the generation capacity of the heater. This is going to be dependent on the number of people using your RV at any given time as well as the climate. For example, if you live in an area with a lot of suns, you won’t need as much power to generate hot water. On the other hand, if you live in a colder climate or plan on using your RV in winter, you’ll want a more powerful heater. 
The heating elements are the “heart” of your electric tankless water heater. They are what actually heat up the water as it passes through the unit.
Resistive heating elements are the most common type used in electric tankless water heaters. They work by passing an electrical current through a metal coil, which then heats up and transfers that heat to the water passing through it. 
Induction heating elements work differently in that they use electromagnetism to generate heat instead of passing an electrical current through a coil. This makes them much more efficient than resistive heating elements, but they are also more expensive.
One final thing to keep in mind when it comes to heating elements is that they will degrade over time with use. This means that over time, your electric tankless water heater will become less and less efficient. Eventually, you will need to replace the heating elements in order to maintain optimal performance.
An RV is a big investment. You want to be sure that your RV is protected against thieves and vandals. A good security system will include motion sensor lights, security cameras, and an alarm system.
You also want to make sure that your electric tankless water heater is properly secured. Most units come with a mounting bracket that can be bolted to the floor or wall of your RV.
Some models also come with a built-in locking device to prevent unauthorized access. If you are planning on leaving your RV unattended for long periods, we recommend getting a model with this feature.
Finally, you should always ensure your RV is against theft and damage. This will give you peace of mind knowing that you are covered in case of an emergency.
When it comes to security, you can never be too careful. By taking the proper precautions, you can ensure that your RV and electric tankless water heater are safe from harm. 
An electric tankless water heater is a great choice for those who are looking for an eco-friendly option. These units do not use fossil fuels, so they produce no emissions.
This means that you can feel good about using an electric tankless water heater without harming the environment. Additionally, many models are highly efficient, so you can save money on your energy bills.
If you are looking for an environmentally friendly option, an electric tankless water heater is a great choice. You can save money and help the planet by choosing this type of water heater.
When you are shopping for an electric tankless water heater, be sure to check the warranty. Most manufacturers offer a one-year warranty on parts and labor.
Some brands, such as Rheem and Bosch, even offer extended warranties of up to five years. This is a great way to protect your investment and get peace of mind knowing that your unit is covered in case of any problems. 
Be sure to read the fine print of any warranty before you purchase an electric tankless water heater. This will ensure that you are covered in case of any problems down the road.
A good warranty is a great way to protect your investment and get peace of mind when purchasing an electric tankless water heater. Be sure to check the warranty before you buy.
Why Should You Get an Electric Tankless Water Heater?
If you’re using a traditional RV water heater, then you’re using a lot of energy to heat a tank of water that sits around until it’s used. A tankless water heater operates on-demand, so you save money on your energy bill by only heating the water when you need it. They also last longer than traditional heaters since they lack many of the internal components that wear down with time.
Electric tankless water heaters, on the other hand, have a few drawbacks. To operate, they require a special circuit, so if you don’t have one in your RV, you’ll need to hire an electrician to install one. Because they heat the water on-demand, they take a little longer to get it hot than a regular RV water heater.
An electric tankless water heater, on the other hand, is the finest way to heat your RV’s water more efficiently. We addressed some of the most frequently asked questions about electric tankless water heaters and offer you our top selections for the finest electric tankless water heaters for RV in this post.
What Are the Benefits and Drawbacks of Electric Tankless Water Heaters?
The tankless water heater has many advantages over traditional storage-tank models. It can provide an endless supply of hot water, because it heats up only when you need it! You’ll never have to worry about running out during your next shower or doing laundry again thanks in part due this handy device that reduces waste by heating just enough for what’s needed at any given time – saving energy as well money from not having those high temperatures left on all day long (and letting them burn out).
The best thing about electric tankless water heaters is that they’re much more energy-efficient than storage unit models. These small, portable devices don’t have to continually reheat and maintain large volumes of stored hotness; so you can expect them to use less power overall! In fact – even when compared with newer standards in homes today ($100 saved per year on average!)”-you’ll find there are still huge savings available by going this route instead.
However, electric tankless water heaters do have a few drawbacks. First, they require a dedicated circuit breaker and electrical outlet, which can be expensive to install if your home isn’t already set up for it. Additionally, electric tankless water heaters are great for those who want hot showers on demand, but they can be difficult to use in larger households because of their lower flow rate. Additionally the wait time after turning them on before you get warm water might seem like an eternity when compared with gas models that start providing instantaneously no matter how many people are using it at once!
Electric tankless water heaters are a great choice for those looking to save money and live in an energy-efficient home. They have many advantages, but they do come with some drawbacks as well! Be sure to weigh the pros and cons carefully before making your final decision.
How to Replace a Tankless Water Heater with an Electric Tankless Water Heater
If your old storage-tank water heater needs to be replaced with a new electric tankless unit, the process is actually pretty straightforward. First, shut off the power to your old water heater and drain the tank. Next, disconnect the cold and hot water lines from the unit. Then, remove the gas line (if applicable) and any venting materials. Finally, disconnect the electrical wires and remove the unit from its mounting bracket.
Now that your old water heater is out of the way, it’s time to install your new electric tankless unit. Begin by attaching the cold and hot water lines to the appropriate inlets on the unit.

Solar Showers for RV
Another option for heating water in your RV is to use a solar shower. Solar showers are easy to install and they are environmentally friendly. The downside of solar showers is that they require a sunny location to work properly and they can take longer to heat up than other types of water heaters.
If you decide to go with a solar shower, make sure that you get one that is specifically designed for use in RVs. Some solar showers are not meant to be used in RVs, so it is important to read the product description before making your purchase.
Whichever type of water heater you choose, be sure to do your research before making your final decision. There are many different types of water heaters on the market and not all of them are created equal. Be sure to read reviews and compare prices before making your purchase. With a little bit of research, you should be able to find the perfect water heater for your RV. 
Natural Gas Heaters for RV
Natural gas heaters are another option to consider if you are looking for an alternative to electric tankless water heaters.
