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 2.64 GPM Propane Portable Gas Water Heater is a solid choice for campers and outdoor enthusiasts looking for a reliable source of hot water. With a maximum power output of 68,000 BTU, it provides instant hot water at a flow rate of 2.64 gallons per minute, making it suitable for showers and washing dishes while camping. Its CSA safety certification, along with features like flame failure detection and overheat protection, ensures a level of safety that is crucial when using gas appliances outdoors.

Portability is one of its strong suits; at just 23 lbs, this compact unit can easily be transported and set up in about 15 minutes. This makes it a practical option for those who frequently move between camping spots. Additionally, the anti-freezing drain plug is a useful feature for users in colder climates, as it helps prevent water from freezing inside the unit.

However, there are a few drawbacks to consider. The requirement for a propane tank may limit availability in some locations, and the initial setup can require caution to avoid gas leaks, which can be dangerous if not handled correctly. While it is designed for outdoor use, it can also be installed indoors with proper ventilation, but this adds complexity to the installation process. Some users might find the need for two D batteries for its LED display inconvenient. CAMPLUX offers support through Amazon, ensuring users have assistance if they face any issues. The CAMPLUX portable water heater effectively meets the needs of campers, providing instant hot water with safety features that enhance user confidence, though careful installation and handling are vital for safe operation.
