Top Features and Benefits:

Portability at Its BEST!

The first thing you gotta love about this tankless water heater is its compact and extremely portable design.

As all the outdoor enthusiasts will nod in agreement, most of the water heaters designed for outdoor use usually come with bigger sizes, and this makes them nearly impossible to transport.

Camplux 5L measures only 11.4 x 5.5 x 14.6 inches and has a lightweight feel of 10 pounds only. This means it can easily fit in the back of your car. Your 12-year-old can also easily carry it to the garage!

The fact that it operates on batteries and its tankless unit uses propane or natural gas means you don’t have to worry about operating in remote places with no access to electricity.

On top of it all, it features a foldable handle that keeps out of the way, further reducing its size while enabling you to set it up outdoors conveniently.

Unbelievably Low-Pressure Startup

Believe it or not, Camplux 5L 1.32 GPM Tankless Water Heater requires only 2.5 PSI to start operating—making it the lowest water pressure startup you can find on the market today.

This is the single most important feature that has made the water heater win the hearts of multiple users across the whole US and even other parts of the globe.

If you’re traveling to areas where water pressure isn’t usually that good, you might not be able to enjoy hot water since most of the water heaters require a decent amount of water pressure to start working.

This is where the Camplux 5L comes in…it employs a unique mechanism that enables it to start working with an incredibly low pressure of 2.5 PSI.

This means you can use the unit anywhere you wish!

Instant, Endless Hot Water Supply

Even with a low water pressure startup, this water heating unit is capable of providing you with instant and endless supply of hot water.

This is absolutely good news for you, given that the main reason why you’re looking for a portable water heater is to enjoy hot water while outdoors.

The unit can heat water to a maximum of 114.8℉ (46℃). The minimum temperature rise is 46.4℉ (8℃). I doubt if there’s anyone who’ll need water that’s hotter than 114.8 degrees F.

It’s also worth noting that the unit has an average flow rate of 1.32 gallons of hot water per minute. Though slow, this flow rate will ensure hot water supply for a longer period of time.

Incredibly Easy to Set Up

When it comes to installing this unit for use, you don’t need to possess any special skills. Likewise, you don’t need to seek the services of a plumber to do it for you.

The installation part is so easy that anyone can do it. The manufacturer has included all the necessary installation equipment—including hose, CSA regulator, shower head and other essential parts— for hassle-free installation.

The only thing you’ll need to make the unit start working is propane gas supply, water, and electricity (or 2D batteries).

Maximum Safety Guarantee

Your safety and that of your family should always be a priority when it comes to water heating units.

You can’t ignore the fact that unexpected incidences can happen anytime and harm you and your loved ones.

That being said, you’ll be pleased to note that Camplux 5L was built with your safety in mind, this is evident from the key safety features that come incorporated into it.

These safety features include a 20-minute automatic safety device, oxygen depletion safety shut-off protection, anti-freezing protection, and even the flame failure device.

Not many companies care to include all these features in their water heaters, making this Camplux product stand out from its competition.

Frequently asked questions:

2. Can I operate this unit using a 1-pound propane tank instead of the stated 20-pound tank?

YES, you can run the water heater using 1-pound propane tank. However, you shouldn’t expect it to last as long as the 20-pound tank will. You’ll definitely need to refill it sooner.

No, it should only be mounted vertically. Otherwise, the batteries will continue to spark and the water valve will fail to work/open.
