Quick Comparison Chart

1. Camplux BW211 — Best Overall

The highest-rated camping water heating system is the Camplux BW211. Camplux is a renowned name in the water heater industry, and its outdoor selection is no exception to its excellence.

With a portable design and propane-fueled setup, this is a heater you can take anywhere. Its tankless functionality allows for continuous use, which means you never have to worry about running out of hot water mid-shower.

Tankless heating means water heats up only as required, saving energy and gas money. High-efficiency combustion technology makes it budget and environment-friendly.

The heater comes with a standard 5-foot propane line and a versatile toolkit. It requires 2 D battery cells for ignition, but you need to buy these separately as they’re not included.

Advanced safety features include a flame failure device and overheating sensor, making it highly reliable for personal and family use. By connecting it to a flue pipe, you can convert it to a home water heater as long as your bathroom is well-ventilated.

Camplux operates customer service contact centers 24/7, so you can reach them for assistance at any time.

2. Rinnai Indoor Tankless — Best Continuous

With a solid online presence, hundreds of raving reviews, and excellent customer service, this gas-powered heater comes in at a close second for the best portable water heater. This heater comes second to Camplux’s BW211 only because of tech support.

The support here is good, but Camplux’s is just slightly better.

This gas-powered heater works in a continuous manner, which means it works like a home water heating system and gives you the same level of comfort on the go. You’ll need a gas cylinder to power it, which is a camping must-have anyway.

It also requires 2 D battery cells that you would have to purchase separately. The flame-failure and anti-freeze technologies used in this heater are CSA approved, making it safe and reliable for family use.

Despite being one of the best water heating solutions around, it’s considerably affordable, making it an even more compelling and practical buy. This model is particularly popular with families who go on frequent camping trips and require a reliable, easy-to-use heating system.

Since it’s very compact, it works even without an RV. You can store it in the back of an SUV with no problems whatsoever.

One thing to know: you can’t use the water heated by this model for cooking or consumption.

3. Eccotemp L5 — Best Budget Tankless

Another solid contender for the best camping water heater, the Eccotemp L5 comes highly recommended by professional and amateur campers alike. Its compact design makes it a delightful carry-on for camping trips, without adding any extra bulk.

The propane-fueled heater is also tankless, meaning its heating is continuous without the limiting factor of a tank. The ignition on this heater requires 2 D cell batteries as well, which unfortunately aren’t included.

The water pressure can be set as low as 20 PSI, and temperatures can be adjusted between 50 to 150 degrees Fahrenheit, making it highly adaptable. Campers have commended the heater’s ease of use, making it an excellent option for beginners.

The L5 is also lauded for its excellent value for money, making it a good purchase if you’re on a budget. This model also comes with a filter, which means you don’t have to worry about sediments polluting your water when you heat.

Many campers love the heating speed of the L5, which is ideal if you want to minimize waiting times. Eccotemp highly values customer service and promises practical or appointment-based support in case you ever need it.

4. Foruee Portable — Best Design

The Foruee propane-powered water heater is an aesthetically pleasing option for those who like their gadgets in black. Its design is compact and minimal, with curved edges and matte colors that make you always want to keep it in plain sight.

The packaged showerhead is a wonderful stainless steel one and is of very high quality. The showerhead offers many pressure and stream options, giving you a luxurious shower experience.

This heating system is surprisingly premium for the price point, giving you a high-end experience even when you don’t expect it. The startup pressure and gas requirements are minimal, making the heater super easy to set up even if you’re a beginner.

The 2 D batteries required for the device need to be purchased separately, though.

The heater has a shut-off procedure in case of oxygen depletion or overheating, which makes it very safe and reliable. It also offers anti-freeze protection, which means you can camp with it in sub-zero climates without any trouble.

5. Marey GA5PORT — Best Lightweight

Marey’s LPG-fueled GA5PORT is a highly rated offering that you can’t go wrong with. It’s simple, straightforward, and requires minimal effort to set up, making installation and usage hassle-free and easy.

The heater is designed to maximize ventilation when used outdoors, which is a nice touch.

It requires 2 D batteries, but they’re not included within the box. Weighing only 12 pounds, this is one of the lightest water heating devices out there, which means you should opt for it if portability is essential to you.

The GA5PORT has phenomenally good ratings, especially for ease of installation and ease of use. Users also love the value of money offered by this device, making it a solid mid-ranger and a go-to tool for anyone on a budget.

It only offers one fixed water temperature, though, so if you would like the luxury of adjustable heat, another option would be more feasible. The unit offers functionality up to an elevation of 6,000 feet, so if you plan a trip to the mountains, you should take the GA5PORT with you.

Marey aims to be a green company, making it an apt choice for campers who care deeply about the environment.

6. Camp Chef Triton — Best Durable

This is another highly rated and well-loved product with the most straightforward possible functionality. Made with steel, the Triton’s industrial design is durable and reliable, so you never have to worry about anything snapping off.

Its heat settings and water flow are fully adjustable, allowing you to customize your usage as you go. The Triton is propane-fueled, and it supports the usage of a 20-pound bulk tank.

Ignition requires 2 D battery cells that are sadly not included.

It also comes with a stand that allows you to hang it wherever you find the right spot, making it easy to shower. It’s also easy to carry around, but at a whopping 15 pounds, it’s not nearly as lightweight as some of the other products mentioned on this list.

However, in exchange for not being lightweight, the device gains excellent durability, which many users prefer.

Plus, the showerhead comes with a wall attachment and offers three different streams, including shower, mist, and jet. The shower hose is 8 feet long and you can get 11 hours of continuous use from one standard gas tank.

7. EZ 202 Tankless — Best Auto-Ignition

The EZ 202 is a straightforward, no-nonsense water heating system with stellar reviews. It’s gas-fueled with 2 D battery ignition, which is pretty much the standard for such technology.

However, batteries aren’t included with the unit and need to be purchased separately.

The design is aesthetically pleasing and minimalistic, so it won’t get in the way of any pretty landscapes, even if you mount it to your RV. The heater only offers three fixed heat settings, though, which means if you want more control over water temperature, you’ll probably prefer another product.

Still, the device is hard to ignore with a heating rate of up to 4 gallons per minute. The EZ 202 is easily one of the fastest portable water heaters around.

It uses a no pilot light design and automatic-ignition settings to maximize efficiency.

It also works well at higher altitudes, which is great if you’re one for the mountains. The device is perfect for camping, fishing trips, hikes, hunting trips, and other such getaways, but may not be ideal for heavy, long-term use.

8. Advanced Elements Solar — Best Solar

If you enjoy innovative fun equipment for summer camping, the Advanced Elements Summer Shower is perfect. It works like a collapsible plastic backpack that you fill with water and leave in the sun to heat.

Since it relies on solar heat, this package is best suited for sunny, warm climates. The collapsible showerhead has on/off settings for convenient showering on the go.

It has a fun design with silver panels and an illustrative sun logo. The bag is extremely portable, weighing just 1 pound and 4 ounces when empty.

It includes compartments for toiletries and Velcro straps for washcloths. The 5-gallon version even hosts a reflective mirror, giving you the feeling of a full shower room.

Using solar heat makes this a very green alternative to fuel-powered heaters.

9. PGYFIS Solar Bag — Best Eco-Friendly

The PGYFIS shower bag works like the Advanced Elements Summer Shower, but it’s more portable and eco-friendlier. It’s made of high-quality, environmentally friendly materials, which make it an excellent green alternative to traditional heaters.

The bag comes with a showerhead with adjustable water flow, allowing for a more customizable shower experience. It’s also durable and sturdy so that you can take it with you on rough treks and tougher expeditions.

Equipped with a temperature sensor, the bag allows you to monitor the water heat level so you can regulate it easily. The bag also features a hook for easy propping up and hanging, as necessary.

It still relies on solar heat, so if you’re camping in cold places, you’re better served by another one of the heaters mentioned above. Its simplistic design may not be for everyone, but its significant affordability and its ability to be folded up and put away make it pocket-friendly in more ways than one.

10. Double Tap Charcoal — Best Traditional

This handmade charcoal heater is a low-maintenance alternative to gas and electric water heaters. This eclectic resource can save your day with relative ease if you run out of gas or battery power.

You need to light up some charcoal and insert it in the bottom compartment, and you can fill the 4.5-liter reservoir on top with water to heat it. It’s highly practical and can also be lit with wood, in case you don’t have charcoal.

A secondary reservoir comes attached to the main one, which is often used for making tea. The heater also has taps, which you can use to fill containers or to wash hands directly.

Designed with a removable chimney on top, the water heater can be used as a source of heat and can serve as an alternative to a campfire. Despite its excellent design, the entire setup only weighs 1.9 KG, making it one of the most lightweight and portable heating supplies mentioned so far.

While this may not be the most technologically advanced gadget on the market, its simplicity and practicality make it appealing, mainly to keep as a backup.

How We Evaluated

We evaluated each camping hot water heater based on the following criteria:

Buying Guide: Choosing the Best Camping Hot Water Heater

Propane Tankless vs. Solar Bags vs. Charcoal

Propane tankless heaters provide the most consistent and powerful hot water delivery, making them ideal for families and extended camping trips. Solar shower bags are the lightest and most affordable option, but they depend on sunny weather and offer no temperature control.

Charcoal heaters are a traditional low-tech alternative that works without batteries or gas lines.

Power and Battery Requirements

Most propane camping water heaters require 2 D cell batteries for ignition, which are almost never included in the package. Make sure you’ve compatible batteries before heading out.

Solar bags require no power source at all, making them the simplest option for off-grid adventures.

Key Factors to Consider

• Weight and portability range from 1 pound for solar bags to 15 pounds for heavy-duty steel heaters. Choose based on how far you need to carry the unit.
• Temperature adjustability varies significantly. Some models offer a 50 to 150 degree Fahrenheit range while others have a single fixed temperature.
• Safety certifications like CSA approval and built-in flame failure devices are essential, especially for family camping trips.
• Fuel runtime determines how long you can use the heater before refueling. Steel models like the Camp Chef Triton offer up to 11 hours from one propane tank.
• Customer support matters when you’re setting up a heater for the first time. Brands like Camplux offer 24/7 support, while others respond fastest via email.

Sizing Your Camping Water Heater

For solo campers or couples on short trips, a solar shower bag or compact tankless heater is sufficient. For families or groups needing multiple showers per day, a propane tankless heater with a high flow rate and wide pressure range delivers the best experience.

If you camp at high elevations, look for models rated for 6,000 feet or higher. For marine adventures, our best boat hot water heaters guide covers heaters designed for the water.
