CAMPLUX 5L Outdoor Portable Water Heater - Instant Hot Water

In this review of the CAMPLUX 5L Outdoor Portable Water Heater the bottom line is simple: this tankless propane unit is best for campers, RV users and remote-cabin owners who need an easy-to-carry instant hot water solution. The biggest reason to buy is its portable, lightweight design combined with a 1.32 GPM flow and 28,000 BTU maximum output which delivers usable hot water without preheating. Setup is straightforward and the CSA safety standard features give added peace of mind for outdoor use.

Key Features

• CSA safety standard: Built-in flame failure, anti-freezing drain plug and overheat shutoff provide multiple safety layers for outdoor and seasonal use.
• Portable design: At about 10 lbs with a foldable handle and compact footprint it is easy to carry and mount for showers or cleaning tasks.
• Instant hot water: 28,000 BTU maximum output and a 1.32 GPM flow rate deliver on-demand hot water as soon as the tap is opened, no tank preheat required.
• Low pressure startup: The magnetic flow sensor allows ignition at low water pressures of 3.0 PSI, useful for rural sites, RVs and boats with weak supply pressure.
• Anti-freeze drain plug: Drains residual water to help prevent freezing during storage or in cold environments, protecting the unit.
• Simple installation: The unit hangs from a top/back mounting bracket and claims roughly 15 minutes to install with basic plumbing and propane hookup.

Who It's For

This water heater suits people who need a compact, portable hot water source for outdoor showers, campsite use, RV trips and remote cabins where mains hot water is not available. It is also practical for brief utility tasks like washing gear or rinsing off after a day outdoors.

Those who need very high flow rates, commercial continuous heavy-duty use, or a unit guaranteed for many years of daily operation may want to consider larger or permanently installed alternatives. Also, if a user cannot check gas fittings and leaks before use, a professionally installed hard-plumbed system would be safer.

Pros & Cons

Pros

• Lightweight and portable form factor makes it convenient to move between RV, campsite and cabin.
• CSA-approved safety features and automatic shutoffs add protection during operation.
• Ignites and delivers hot water at low inlet pressure, expanding usable locations.
• Simple battery ignition and straightforward plumbing reduce setup time.

Cons

• Some users report inconsistent temperature performance and occasional ignition or leakage problems, so quality can vary unit to unit.
• 1.32 GPM is sufficient for a single shower or sink but may be limiting if higher flow or multi-point use is required.

Our Verdict

The CAMPLUX 5L Outdoor Portable Water Heater is a practical, value-oriented choice for campers, RV owners and remote-cabin users who want on-demand hot water with easy portability and safety features.

Frequently Asked Questions

Can this unit be used on an RV or boat?
Yes, it is suitable for RVs and boats thanks to the 3.0 PSI low pressure startup and compact mounting options, but always check gas fittings and ventilate properly.

How is the unit powered for ignition?
Ignition is battery powered using two D batteries at DC 3V, with an estimated battery run time around six months depending on use.

Will it prevent freezing if stored in cold weather?
The anti-freezing drain plug allows discharge of residual water to help avoid freezing, but additional winterizing measures are recommended in very cold climates.
