10 Best Camping Water Heaters 2025 in the United States

The Rinnai V53DeP is a propane-powered tankless water heater designed primarily for outdoor use, making it a solid choice for camping or other off-grid water heating needs. It delivers a strong flow rate of 5.3 gallons per minute, which means you can have continuous hot water for multiple tasks without running out. Its heating capacity is quite powerful at 81 kilowatts, so it heats water quickly and efficiently. The unit is compact and lightweight at 33 pounds, helping with portability and making it easier to install even in tight spaces. Since it runs on propane, you don't need electricity, which is a big plus for camping or remote areas.

The heater is high-efficiency and includes features like enhanced scale detection to extend its life, plus it offers Wi-Fi capability for remote monitoring, although this might be less useful outdoors or away from Wi-Fi coverage. Safety-wise, professional installation is recommended to ensure proper setup and secure operation, which means this might not be the best pick if you're looking for a quick DIY solution. It also comes with a strong warranty covering parts and labor, giving extra peace of mind.

Because it’s designed for outdoor installation and professional setup, it might not be the easiest or most portable option for casual campers who want something simple to carry and operate. However, if you need reliable, continuous hot water with propane fuel and don't mind a bit of setup effort, this model fits well.

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.

The CAMPLUX 2.64 GPM Tankless Propane Water Heater is a solid choice for camping and outdoor activities, especially if you need instant hot water on the go. It runs on propane, which is common and convenient for camping, and delivers a steady water flow of up to 2.64 gallons per minute—enough for most outdoor showers or washing needs. Its heating capacity of 68,000 BTU means it can heat water quickly, with temperatures adjustable from 50°F to 122°F, which is great for comfort in different weather.

The unit is lightweight and compact (weighing 18 lbs), making it easy to carry and install, fitting well in cabins, barns, or even for road trips. The installation process is straightforward since it comes with a pre-installed gas regulator and quick-connect shower kit, so you won’t need special tools or skills. Safety is covered with CSA certification and overheating protection, which adds peace of mind for family use.

It works best with water pressure between 3.6 and 110 PSI; if you're in an area with low water pressure, a separate water pump might be necessary. It also requires 2D batteries to operate the ignition and controls, which aren’t included. While mostly designed for outdoor use, it can be installed indoors if proper ventilation is in place, though that might be more complex. For campers or outdoor enthusiasts looking for a reliable, portable, and fairly easy-to-use propane water heater, this model offers a good balance of power, portability, and safety features.
