10 Best Portable Water Heaters To Buy In 2024


We all deserve comfort, amidst the stress that comes with modern day activities.  However, this convenience gives us a better taste of life as well as relieves us of stress.

There are a lot of things that can bring convenience in this modern world; one of them is going on a long trip if you’re an adventure enthusiast, whether camping, hiking, swimming, kayaking, or boating. 

One thing that makes your trip even more fun is having a long hot bath after every activity of the day to cool your body and prepare for the night’s sleep. 

And if you’re out fishing all through the night, a quick hot bath in the morning can wash off the cold and prepare you for morning sleep. Some might resort to using a campfire, but a propane-powered portable water heater is better. 

This is because the former is not so eco-friendly, not body-friendly, and takes more time to produce the needed heat, while the latter gives you instant access to the hot water you so desire.

However, selecting the best model for you can be a daunting task as there are many excellent ones out there. We understand this, and that is why we have made research and compiled a reliable list with great options to choose from. 

We do this so that you don’t have to stress when next you visit the store to get one. But first, let us look at some benefits of portable water heaters, and factors to consider when selecting one.

What are the Benefits of Buying a Portable Hot Water Heater?

Buying a portable water heater is geared towards fulfilling an objective: to enjoy much snugness and convenience during any outdoor activity. 

One might say it will not bring so much change to our lives at once over the already existing stationary water heater. But, there are a few advantages associated with portable water heaters over stationary ones. Let’s see what they are below:


Without too much debate, one major advantage of a lightweight and portable heater over a stationary one is that the former makes heated water available to you almost in no time when you need it. 

You can leave your house, go on a camping trip alone or with your family, and still carry your heater with you in the car.

Hot Water Use in the Backyard and Garden

You know how the heels of your boots can be after walking on the moist backyard soil for a while. You know how your clothes too can be if any of those dirt gets to them as well as your equipment.

Now, imagine needing to clean up all the things you use after a long garden work so that you don’t bring them into the house. 

We both know trying to do the washing with cold water will turn out stressful. And even if you wash them, especially your clothes, they may forever carry marks marking the spots the dirt gets to.

In essence, having a portable water heater might come in handy right there in the backyard, providing you with almost instant hot water to carry out all efficient cleanings.


If you’re the type of person that believes in spending some long, quality, time all by yourself; away from the sound of people and civilization, you will need some basic utilities as you embark on your journey of solitude. 

One of the things you might need to consider is a portable water heater, especially if you will be camping around rocks or water where there’s a high tendency for the low temperature at particular periods of the day.

Energy Efficiency

Portable water heaters have better energy efficiency than electric ones. This is because they are powered by propane. 

Moreover, they work faster to give you your desired hot water almost immediately, so that you can better save the energy required for heating large amounts of water for a very long time.

Hot Shower On Outdoor Trips

Owning a portable water heater on a camping trip easily connects you to the abundant freedom nature offers. 

After your long walk to and around the mountain, long cooking hours, a long surfing day, or even a long angling night at the shore, having a quick hot shower can add to the perfection and prepare you for a sound sleep.

What beautifies your experience, even more, is the ability to not think about the cold or how to get rid of stubborn stains that require hot water washing on your clothes when you know your portable water heater is readily available.

Cabin In the Woods

The primary purpose of going on camping is to enjoy some time alone with your family or all by yourself. This means you will be miles away from basic amenities like pure water and electric supply, and you will not be able to carry a large stationary water heater along. 

That will be a waste of available resources that can be channeled somewhere else. Simply having a portable water heater will reduce the total stress you go through by providing consistent running hot water.

Interestingly, unlike stationary water heaters that can’t be used on camping trips, portable water heaters can be used in your house. 

Having one can serve as a solid backup for your existing standing water heater in case there’s an issue with the electrical connection in your home, or there’s a power outage due to a disaster. 

Although it might not be able to supply all the hot water demands in your home, it will serve you efficiently until you get your electrical power back and running.

What To Consider When Selecting A Portable Camping Water Heater

Now that you know the benefits a portable water heater can offer you, you must also know that there are a lot of brands currently available on the market. 

Knowing what sets some models ahead of others is important to help you make the right decision in selecting one. Here are a few factors to consider:

Power Source

The power source is unarguably the number one factor to consider when selecting the best portable water heater. You have two options to choose from: propane and electric water heaters. 

Electric heaters require that you find an electric source wherever you’re which is only mostly feasible at home, for those who have small apartments or RVs. 

A propane heater on the other hand comes in handy and has become popular because you do not need electricity to power it. 

Moreso, you can use it outdoors too, when you go on a little trip with your family. However, for it to perform, you will always need to take a propane tank along with you wherever you go.

Size and Weight

The size and weight of your portable water heater depending on your needs and the purpose you want it to serve. 

Generally, portable water heaters are compact and slightly lightweight, so this shouldn’t be a problem. However, if you’re going for the more powerful and sophisticated models, expect them to be heavier.

A smaller, transportable model will be an ideal choice if you’re going on a camping or hiking trip. But you can drop the idea of transportability and take the heavier, more powerful one if you’re just planning to use it in your small home

Temperature Range

It is advisable to go for a portable heater with a wide temperature scale. It provides better versatility for wherever you want to take it to and whatever you intend to use it. 

For instance, versatility comes to play when you choose to leave the beach for the mountains. The heat you’d need on the mountain wouldn’t be the same as on the beach. 

You’d need more. Some portable heaters are not powerful enough to provide high temperatures in cold weather. If you’re a hiker, go for one that will give you that as well as save energy, without the need to break the bank.

Flow Rate (Gallons Per Minute)

Different tasks require a different quantity of hot water. GPM displays the flow rate of your portable water heater. That is, it shows the quantity of hot water that can be available for you per minute. If your tasks require a higher amount of hot water, then you’ll need a portable water heater with a higher GPM.
