CAMPLUX Portable Water Heater 1.58 GPM - Compact Outdoor Hot Water

In this review of the CAMPLUX Portable Water Heater 1.58 GPM, the bottom line is simple: it delivers reliable hot water for outdoor and off-grid use without heavy setup. The unit is aimed at campers, RVers, cabin owners and anyone who needs a portable, propane-powered solution; the single biggest reason to consider it is instant hot water on demand from a lightweight package that is easy to carry and install. The reviewer found it especially useful where water pressure is low and quick warm water is preferable to hauling large tanks or using electric heaters.

Key Features

• Portable and lightweight: At about 13 lb with a foldable handle, it is easy to carry, hang and move between sites.
• High output power: With a maximum of 41,000 BTU/hr the unit produces hot water quickly for outdoor showers and sink use.
• Instant hot water flow: The rated flow of 1.58 gallons per minute provides usable warm water for rinsing and short showers without long waits.
• Simple temperature control: ECO and Full knobs plus an LED display make it straightforward to set an ideal water temperature.
• Low pressure start: Starts at a minimum of 3.0 PSI, so it works in rural and remote cabins or other low-pressure sources.
• Easy installation: Connect a water supply and a standard 20 lb propane tank and the heater is ready to run.

Who It's For

The CAMPLUX portable heater is best for campers, RV owners, and cabin users who need a lightweight, mobile hot water source that can be installed with basic hookups and a common 20 lb propane tank. It is a practical choice for those who value portability and quick heat generation over high-volume flow.

Those who need continuous high-flow output for multiple fixtures or long household-style showers should look elsewhere, as the 1.58 GPM flow and propane tank configuration target outdoor and light-duty applications rather than whole-house performance.
