Luxury Camping: A Guide To The Best RV Tankless Water Heaters

Everyone likes an escape from their day to day life, and one way to take weekend getaways that will not break the bank is to take your RV into the mountains or the forest.

You can rough it during weekend trips, but nothing is more relaxing than a shower at night, especially if you have been hiking or doing strenuous activities during the day.

Did you know that most water heaters in an RV only have a capacity of six gallons of water?

This is enough water for you, but when you are traveling with your family, there is no way that a family of four can get a shower with a standard water heater. They can be upgraded to hold 10 gallons of water, but is that really enough?

I find that even the upgraded standard water heater is not sufficient for my RV needs, which is why I decided to go with a tankless water heater.

With this type of unit installed in your RV, you will have all of the hot water that you need, which means that you can even take a bath if you have a tub inside your RV.

I created this guide to help you find the best RV tankless water heater for your camping needs. Before we dive into the reviews, let's take a look at the different types of tankless water heaters and some of the benefits of having one in your RV.

Propane Vs. Electric

Propane

When you have a tankless water heater that is powered by propane, the water is heated when it crosses over a flow sensor by a gas burner.

This method gives you hot water almost immediately, and as long as you have a full hook up where you are camping, you will never run out of hot water.

Electric

An electric water heater does the same thing, but it is a more compact unit that actually allows you to adjust the temperature of your hot water. These models also tend to make less noise as they heat the water.

In addition, with this type of heater, you will never run out of hot water. There are also battery operated models that you can make use of when you are camping off of the grid.

Advantages Of A Tankless Water Heater

Via Amazon.com

I already mentioned that with a tankless water heater, you will have a supply of hot water that never runs out.

If you stick to the standard tank design, the most you can have is 10 gallons of hot water at a time, which may not be enough for all of your RV needs, especially if you are traveling with your family.

What are some other advantages of a tankless water heater?

  • A tankless water heater is a great way to save space. Most RVs already have limited space, especially if you are traveling with your family. A 10-gallon tank does not have a small footprint, but going with a tankless model will allow you to install it in the smallest spaces of your RV. In fact, many of the tankless water heaters on the market can fit into a hidden space within the bathroom of the RV.
  • There is no wait time for hot water with a tankless water heater. If you have ever used a standard water heater in an RV, then you understand that when the tank gets low, it needs to be refilled and reheated, which can take a few minutes. A tankless water heater provides hot water almost instantaneously.
  • You can save energy using a tankless water heater. In fact, a tankless water heater can use up to 50 percent less propane than a standard water heater. Electric models utilize less energy as well, which helps decrease your footprint on the environment.

Considerations For A Tankless Water Heater

As with any purchase you make for your RV, there are a few considerations that you should look into before making a purchase decision. Here are a few of the most important things to think about:

Size And Installation

Via Amazon.com

Even though these tankless water heaters are smaller than many of the standard water heaters that come in an RV, you still need to ensure that you have enough space to install one that you select.

Installation is typically painless when it comes to tankless water heaters, but here is a custom install video that may interest you.

Propane And Energy Usage

Consider the length of the trips that you make and the amount of propane and energy that each tankless water heater will use during that period of time.

The energy usage may vary for each unit, but they will all use less than a standard water heater, which is better for the environment.

Amount Of Water

How much hot water can the tank create per minute? If you want a lot of water pressure, you may need a model that delivers more water per minute. 

In addition, some models also have knobs that allow you to adjust the water pressure, which allows you to customize your shower a bit.

Warranty

Many tankless water heaters come with a warranty, so check to see how long it is on the model that you purchase. Some models may even come with a lifetime warranty.
