10 Best Camping Water Heaters 2025 in the United States

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.

The Rinnai RE199eN is a natural gas tankless water heater designed for outdoor use, making it a strong option if you need reliable hot water while camping or for other outdoor activities. It delivers a high heating capacity with 199,000 BTUs and can provide up to 9.8 gallons per minute, which means it can easily supply hot water to multiple faucets or showers at the same time. This makes it suitable for larger groups or setups where several people might need hot water simultaneously.

Since it runs on natural gas, it’s efficient for extended use but requires access to a gas supply, which might not suit all camping locations. The unit is fairly compact, about the size of a small suitcase and weighing around 53 pounds. This makes it portable enough to move or install outdoors but less ideal if you’re looking for a lightweight, backpack-friendly heater.

In terms of ease of use, the heater features an LED display that shows service reminders and error codes, helping with maintenance and troubleshooting. Installation is recommended to be done by a professional, so it’s not a simple plug-and-play device, which could be a downside if you want something ready to go without expert help. The unit includes standard built-in safety protections common in tankless water heaters, and its outdoor design helps prevent indoor gas or vapor buildup. It also conserves energy by only heating water when needed.

If you want steady, on-demand hot water outdoors and have access to natural gas and professional installation, the Rinnai RE199eN offers powerful heating and good flow rates. However, if your camping spot lacks gas or you prefer ultra-portable gear, a smaller propane or electric model might be more convenient.

The CAMPLUX Battery Powered Portable Water Heater, Nano 3 Pro, is designed for outdoor enthusiasts who value the comfort of hot showers while camping or hiking. Weighing just 13.7 lbs, this unit is lightweight and portable, making it easy to transport to various locations. One of its standout features is the instant heating capability, allowing users to enjoy warm showers within seconds. With a maximum water flow rate of 3 gallons per minute and a heating capacity of 20,500 BTUs, it provides an efficient solution for outdoor washing needs.

Portability is a significant strength here, as it includes two durable handles for easy carry. The device supports multiple charging options, such as a built-in 4,000 mAh battery, which can provide up to 100 minutes of use when fully charged. The fact that it can charge during operation adds to its convenience.

Safety features such as flame failure protection and low water flow protection are commendable, but users should still exercise caution, particularly in ensuring the unit is set up correctly to avoid mishaps. The maximum temperature of 122°F might not be sufficient for everyone, especially on colder days.
