The 7 Best Portable Hot Water Heater for Camping & Other Recreation

Best Portable Hot Water Heater for Camping Reviews

Hot water is always a necessity, especially on colder days. When you’re on the go, access to clean water isn’t easy, let alone hot water.

In times like this, portable tankless water heaters could be a game changer.

Whether you are going camping with your family or looking for a poolside shower, you can really benefit from one of these.

If you want the best portable hot water heater for camping or other outdoor activities, you’ve come to the right place.

In this article, we have discussed our top picks for such heaters that you can use to get clean hot water when you’re stuck in the middle of nowhere.

Types of Portable Tankless Water Heater

Primarily, there are three different types of portable tankless water heaters to choose from. Depending on your needs, you can decide which one is suitable for you with the help of the detailed descriptions provided below.

Electric Water Heater

First, we have electricity-powered heaters that require power from an external electrical outlet. This means that considering their portability, they cannot be used entirely off the grid.

Most of these heaters run on 110V and use a small amount of current. So, they may require slightly longer to heat water.

Compared to the other types, these are less portable in a sense. But they are highly efficient and extremely dependable.

Gas or Propane Water Heater

Next, there are gas-powered heaters.

The energy source for gas-powered heaters, also known as propane water heaters, is gas.

As propane is more of a lightweight and reliable source of energy, these are usually the fastest of all heaters in terms of performance.

Solar Water Heater

Last but not least, there are solar-powered water heaters. They are without a doubt the most fuel and cost-effective.

They do, though, take much longer time to function and do not last for long.

What to Look for in Portable Water Heater

Portable Tankless Water Heater

Now that we have discussed the best tankless water heaters on the market, you must have a better understanding of these products. But you are still not ready to make the right choice.

First, you have to consider some essential factors, and based on those, you can buy yourself a portable water heater.

Source of Power

As mentioned above, there are mainly three different sources of power when it comes to portable tankless water heaters.

Electric water heaters require some form of electricity. So, if you are completely off the grid, you can’t have one of these.

Gas water heaters are useful for almost all purposes. But you will have to take your propane tank with you. If you’re willing to take that extra trouble, propane heaters might be more fitted for you.

As for solar ones, only take those if you aren’t in a hurry. They will take a lot longer to heat your water.


Check to see if your water pump is heating your water as excellently as it can. The British Thermal Unit (BTU) input is used to calculate this.

Higher BTUs are favored because they allow your water to heat more quickly.

Safety Features

Another extremely important factor is safety. If you get a water heater with poor safety standards, you might face unfortunate situations involving severely hot water.

So, make sure you get a heater that has advanced safety features. Some features, like anti-freezing protection, flame protection, automatic shut-down feature, are absolute necessities. Be sure to look out for those.

Flow Rate

This is another significant factor that you can’t afford to overlook. Basically, the volume of water that runs into your water heater is referred to as the flow rate.

Portable water heaters have flow speeds ranging from 1 to 3.5 GPM (Gallons Per Minute). Higher flow rates are preferred, as it means you will obtain hot water faster than lower rates.


Size is always a key factor when choosing any portable machine. And, it is no different for a tankless water heater.

You have to make sure that the heater isn’t too big, but you also have to make sure that it is enough to provide a decent amount of water at a time.

The majority of portable heaters weigh between 15 and 20 pounds. You should make your choices based on how much you can take with you.


Unlike heaters with tanks, most of these don’t have a certain capacity to hold water. As you can connect the machine to a hose and water source, you should get an endless supply of hot water. So, that shouldn’t be much of an issue.


If longevity is an issue for you, and you want a heater that will last you a long time, you should avoid solar water heaters.

Electric and propane water heaters are both great options for you. But among those, some are made with significantly better parts and components. So, make sure you check for those details as well.
