It was easy to install, it worked instantly, maintained temperature
Reviewed in the United States on May 5, 2025 by Demetrio P.
I bought this to use for a DIY pool heater I built. It's been set up for about a week or so and working great, water output can reach 160 degrees at times, far too warm but nice to know at the settings I'm using the machine isn't straining. It's very sensitive to water and gas pressure so it took me probably 30 minutes to dial in the gas pressure and water flow but once that's complete it's fully automated. So for cons. The manual is useless. It's very sensitive to gas pressure and if you have too much/little it will not ignite, buy a good regulator. Same for water, too little and the igniter won't function. Too much and it has a relief valve that ill drain the water out of the bottom.The display is in Celsius. The water/gas connectors aren't US standard so you'll need adapters. It has a 20 minute built in off timer so you'll need a water pump on a timer that runs for 20 min, off for a couple minutes, and back on if you want continuous use. Here's what I bought for adapters: Gas: Anderson Metals - 54046-0608 Brass Tube Fitting, Coupling, 3/8" Flare x 1/2" Female Pipe GasOne 2109-RED 4 ft High Pressure 0-20 PSI Adjustable Regulator Water: 1/2” G Thread (BSP) Female to 1/2” NPT Male Connector I also went and bought pvc connectors for running my water lines, I took the connector with me to the store but you'll need two 1/2" female 'screw on' connectors to attach hard lines.

I purchased this hot water heater and only used it less than a month. I turned on the hot water tap in my kitchen and heard the ignitor clicking but the water heater didn't light. With the tap still on I went to look at the heater to see what was up. I was met with a forceful fire ball just short of my face. I felt the force, but wasn't burned. The thing hasn't worked since. The item said that it was eligible for return until January 31, 2025. Upon starting the return process, I was met with a message stating that the return window ended November 1st this year. I'm lucky that I wasn't burned and that my trailer didn't burn down around me. It's dangerous junk and should be recalled. Now I'm out a hundred bucks and have no water heater for the winter!

The only reason I didn't give it 5 stars was the low flow. It's not terrible but could be better.

We own two of these.... they are awesome and work well. Very easy to install and the pressure is great. The second one had a pin hole leak in one of the coils and it was promptly replaced by the company. They stand behind their product!

I bought this thinking it was brand new, but it looked like someone had already used it. The water outlet connector was bent and leaking, and there was some corrosion around it. The knobs were super loose and wobbly, and they didn’t line up with the settings like they should. I tried reaching out to customer service, but they didn’t get back to me quickly. Pretty disappointed overall. Not what I expected at all.

You get hot water, however, if you Don't have enough water pressure, it won't run. Unfortunately it only turns down so far, and then just shuts off, which is horrible, I should be able to make warm water not just hot, but I can't. This isn't a cheap water heater, but it's not expensive either, the value is somewhere in the middle. The water only gets hot for a little bit, then you have to have someone turn it back on. Which sux. The capacity of the water is great, because it's on demand. So heats up as it flows. The temperature is in C°, not F° temp. The quality is OK, like it could work better, I think. But for the price, and the fact that it works, is fantastic. It was easy to install as well, just make sure it's level when hanging, or it will NOT work. Must be level when hung. And you shouldn't use it in doors. I just hung mine outside my house, and ran lines inside. Works great!

12/5/24 So my first unit I got would not turn on and after troubleshooting everything I could think of, I reached out to the seller and they sent me a replacement. It works!! Any time I turn my hot water on it automatically turns on and starts heating up. Super convenient for being offgrid. You just need steady water and gas pressure and it works like a charm! 2 years of boiling water for showers is over!! I'll update if it's no longer working. But if I don't update, its still doing the job!
