  • Poor parts used for assembly
Style: Propane 16L
Great water heater for about 5 months now it won’t come on at all. Error message E5 found that the solenoids valve is not clicking on or off when you turn on the hot water and there is absolutely no product support for this product and the solenoid is not available anywhere

  • Don't buy foreign, buy American made with real warranties!
Style: Natural Gas 16L
After purchasing and installing this water heater, it worked for about a week with no issues. Tried hot water at my kitchen sink and no hot water. After contacting Amazon and ultimately the seller, the seller sends back this response: "Dear Customer: Low water pressure or problems with the flow sensor can also affect the normal operation of the product. Check that the water pressure reaches 3.6 PSI. flow sensor problems: clean the sensor, check the wiring, and replace the sensor if necessary. If you have any other questions, please feel free to contact us. Have a nice life." This clearly is not what you'd expect from a manufacturer of a brand new product that you pay good money for and they place the onus on you to repair there defective product let alone that the response they gave, only a tech would even begin to understand and I am a HVAC Tech. What about the 87-year old grandma who has no Flippen idea what any of their response means. China either needs to step up their game it stop selling their crap to the American public. ... show more

  • Very pleased so far
Style: Natural Gas 16L
I think I'm going to be quite pleased with this unit, though I've only been using it a couple of days so far. My main criterion for choosing this was it's dimensions (overall size and location of connections) and, of course, price. Though it has slightly less BTU output that the 10+ year old unit it's replacing, it has given me all the hot H2O that I need. AND, sort of a bonus for me was the auto-temp control, which regulates water and fuel flow to maintain the temperature you set it to. (My old one was manual where you had to estimate the two flows, and adjust seasonally sometimes) And, I think the flow sensor is more sensitive on this than my old one, though admittedly that one had grown insensitive over the years. I'll never go back to a tank, those are one step up from using a vat in the fireplace! ... show more

  • Junk
Style: Natural Gas 16L
My first one did not work more than two weeks. Tried to contact the manufacturer and they only respond in the middle of the night after a week of getting nowhere I bought another and swapped out. This one worked for about 5 months before it stopped working automatically. In order for me to get hot water I have to manually turn it on every time. It's a piece of junk and the seller is not helpful in replying. ... show more

  • Good functional design
Style: Propane 16L
So weigh the pros and the cons with this item. The design is good with no surprises, and it has not had any issues with about two weeks of use. Installation was a breeze especially since I was replacing a similarly sized unit. So now maybe the not so good points. And they are not bad unless you want them to be. The max temperature setting is 150 degrees F not the 167 or so specified in the product description. That's not a real issue unless you are using this unit for hydronic heat or some such. Tech support may give you a method to bypass this feature, but I did not ask. Speaking of Tech support, you may not be too happy. I am a do-it-yourselfer. I examined the interior of this heater and I like it. Good design. Basic. Functional. But absolutely generic. No manufacturer identified and the manual does not provide any information about replacement parts availability. I exchanged emails with the seller (which they did not seem to understand) on this subject of parts availability and the bottom line appears to be when and if you have a problem, you have to go through the seller at Amazon. Not an issue unless you want it to be. I am happy with this purchase, but I would hesitate to do it again. ... show more
