Ranein Tankless Water Heater Reviews From My Experience: Is It Worth It?

You might be tempted to buy the Ranein Tankless Water Heater for its promise of endless hot water and space-saving design, but don’t rush to add it to your cart.
This propane-powered unit claims 4.3 GPM and 100,000 BTU, but my experience and user complaints show it’s often unreliable and leaky.
As a homeowner who tested it for my RV, I’ll share why it didn’t live up to the hype.
From installation woes to performance issues, this review covers my journey, pros, cons, maintenance tips, and comparisons.
Read on to see why you should skip it for more dependable options in your hot water needs.

My Experience with Ranein Tankless Water Heater: High Hopes, Leaky Reality

Last spring, I installed the Ranein Tankless Water Heater (100,000 BTU, $300) in my RV, hoping for endless hot water on camping trips without the bulk of a tank.
The compact unit looked promising, with its 4.3 GPM flow rate and oxygen-free copper heat exchanger.
I hardwired it to my propane system, but the connections were finicky—the 1/2″ NPT fittings leaked on first test, requiring Teflon tape.
Once sealed, it heated water fast, providing hot showers for two people back-to-back.
You’ll expect consistent performance, but my unit sprung a leak at a solder joint after a month, flooding my RV compartment.
I contacted the seller, but their response was slow, and the refund process took weeks.
My friend tried it in his garage for greasy hands, but the greasy buildup made it ineffective.
Analytically, the 10,000-foot elevation rating is great for high-altitude camping, but the poor soldering quality, per user feedback, leads to failures.
I tested it on a weekend trip, and while it worked initially, the leak returned, forcing me to use cold water.
You’ll find the installation easy if you’re handy, but expect potential defects.
My propane consumption was low, but the unit’s noise was noticeable in quiet campsites.
I tried it with a pressure regulator, and flow improved, but leaks persisted.
My only consolation was the quick heating when it worked.
You’ll want a reliable heater—this one isn’t.
This heater’s a budget option, but quality issues make it risky.

I kept at it.
After repairing the leak with plumber’s putty, it worked for two months, but efficiency dropped in cold weather.
You’ll need to insulate pipes for winter use.
My final take: it’s affordable but unreliable—skip it for peace of mind.
