Best Portable Tankless Water Heater Reviews 2022

The invention of the portable tankless water heater or just portable heater has transformed camping trips and other outdoor activities. Gone are the days of standing under a black portable shower bag of cold water. Shivering as a trickle of what was supposed to be “HOT” water trickled out.

Adding insult to injury, solar bag showers don’t hold much water so you had to be quick. And of course, once the water was gone, they had to be filled up and would take hours to get warm again.

Best Portable Propane Tankless Water Heater 2022

Although portable water heaters are usually much smaller in size they are more than capable of producing enough hot water for a great hot shower. Or maybe you are more interested in easily filling the sink with hot water to clean up.

Some, not all portable tankless water heaters require batteries that you can get from any regular store.
Most of these water heaters we reviewed are instantaneous style water heaters, meaning they automatically start heating the water as soon as the first water flow is detected.

Lightweight, moveable water heaters are available in both, gas and electric, if you camp off-grid away from established campsites with power then gas may be your best choice because they can be used without mains power.

But if you are mostly camping where there is power, or have a good solar PV and battery setup an electric unit could be perfect, they are far simpler to set up, don’t require a propane tank and some would argue that electric is safer too.

  • It’s the perfect addition to your RV, camper or cottage. Simply connect it to a 20lb propane tank and you’ll have instant hot water for showers, laundry and dishes.

It also includes a battery operated ignition system so there’s no need for electricity which means this unit can be used. The L10 comes with an integrated 3-stage regulator that will deliver up to 50 PSI of high-pressure hot water and 2.9 GPM (gallons per minute). There are many options on the market for portable water heaters, but Ecotemp’s model is one of the most popular, and for good reason too. Ecotemp has always focused on heating efficiency, safety, reliability and durability.

With this portable tankless heater, you don’t need any additional power source to use it because it’s powered by propane and batteries so there are no worries of finding a mains power supply while camping.

The only downside I found was that you’ll need to set and control the temperature manually, which is no big deal.

Features of Eccotemp L10 Portable Water Heater

Temperature Range

The Eccotemp L10 Tankless Water Heater is the perfect choice for anyone who needs a powerful hot water solution. This amazing machine delivers up to 2.6 gallons per minute of instant, on-demand hot water that ranges from 80-165 degrees Fahrenheit and can be used to run two outlets at one time! With this level of efficiency and performance, it’s no wonder why the Eccotemp L10 Tankless Water Heater is top-rated by customers across America.

High Efficiency

The Eco temp is more of a semi-permanent portable heater. More suited to outdoor showers, horse stables, RV’s and portable work sites. It is very efficient and will provide more than enough hot water in most situations. But it is too bulky and requires more setup than some of the smaller units. Making it not so suitable for camping trips.

Final Thoughts

One of the best features of this water heater is its versatility. It can be plumbed in with standard NPT fixtures, but it also works well off a 12-volt pump if you’re living off-grid or have limited access to electricity. The L10 has an operating range that ranges from 25-80 PSI, so no matter what your situation is, chances are good that the L10 will work for you. So whether you’re looking for space-saving solutions or want to make sure there’s always hot water on hand when needed—the L10 portable tankless water heater could be right up your alley!

Pros

  • Lowest cost heater
  • Stainless steel venting
  • Perfect in size

The pressure this water heater works with is from 3 to 145 PSI. That means it can work in a lot of different situations. If the pressure is very low, the gas will not be lit and the water heater will not work.

Overall though I would say its pretty great!
