10 Best Camping Water Heaters 2025 in the United States

The Kohree Helios 20 Pro is a propane-powered portable water heater designed for camping and outdoor cleaning, delivering up to 20,000 BTU of heating power. It heats water rapidly, reaching a comfortable temperature within seconds, which is great when you need warm water quickly. The unit includes a rechargeable 4,000 mAh battery that allows about 100 minutes of continuous use, and you can recharge it via car cigarette lighter or standard AC outlet, making it convenient for remote use.

Its compact size and multiple handles make it relatively easy to carry and store, though at about 23 pounds, it’s a bit heavier than some other portable options. The package includes a shower head with adjustable spray patterns and a pump assembly, providing a complete setup for washing or showering outdoors. Safety is well covered with features like tilt protection, overheat shutoff, and flameout detection; however, it needs to be used in a well-ventilated area and requires draining after use to avoid damage.

This heater is ideal for campers and outdoor enthusiasts who want a reliable and powerful hot water source with safety features and portability in mind, but those looking for ultra-lightweight gear might find it somewhat bulky.

The CAMPLUX Tankless Water Heater is a portable propane-powered unit designed specifically for outdoor use, such as camping. It offers decent heating performance, producing up to 1.32 gallons of hot water per minute, with a temperature increase of about 115°F at its peak flow rate. This makes it suitable for quick warm showers or washing tasks when off-grid. It runs on propane and requires two size D batteries for ignition, which means you don’t need electricity, adding convenience for remote locations.

Weighing just 10 pounds and featuring a compact design with a folding handle, it’s easy to carry and set up in under 10 minutes. The package includes a shower head, gas regulator, garden hose, and installation hardware, so you get most of what’s needed to start using it right away. Safety is well-handled here, with six built-in protections like flame failure, overheating, low water flow, and anti-freezing, plus it has CSA certification, which ensures it meets recognized safety standards.

This CAMPLUX model is a solid choice for campers or anyone needing a lightweight, portable propane water heater with reliable safety features and decent heating capacity. Its ease of use and included accessories make it beginner-friendly, though it’s best suited for small-scale outdoor water heating rather than heavy or indoor use. The flow rate is modest—while good for outdoor showers, it might not be ideal if you need a higher water volume quickly. Also, it requires careful winter care, as freezing can damage the heater and is not covered by the warranty. Installation must be done carefully to avoid gas leaks, and the heater is mainly intended for outdoor use unless you have proper indoor ventilation and a flue pipe.

The CAMPLUX Portable Water Heater is an excellent option for campers seeking a convenient and effective way to enjoy hot showers outdoors. Weighing only 10 pounds, its lightweight and portable design make it easy to carry and set up, ideal for off-grid adventures or camping trips. The setup process is straightforward, typically taking around 10 minutes, and the temperature dials allow users to easily adjust the water temperature to their liking.

With a water flow rate of 1.32 gallons per minute (GPM) and the ability to function with a low water pressure of just 3.0 PSI, this tankless water heater is versatile enough for various outdoor settings. It effectively provides warm showers, and the design allows you to conserve water by turning the shower head on and off while soaping up.

Safety is a key feature of the CAMPLUX heater, as it comes with a CSA safety approval and multiple protection mechanisms, including anti-freezing, over-heating, and flame failure devices. These features provide peace of mind while using the heater in outdoor conditions. The unit also includes a comprehensive package with essential accessories, enhancing its value. Proper maintenance is crucial, especially in cold climates, as improper storage can lead to freeze damage. Users need to ensure they follow the guidelines for draining the unit and disconnecting gas and water lines when not in use. Also, the reliance on propane means that users must ensure they have a compatible gas bottle, which adds an extra step in the setup process.

The CAMPLUX Portable Water Heater offers a blend of convenience, safety, and efficiency for campers and outdoor enthusiasts, making it a solid choice for those who prioritize hot water accessibility in remote locations.
