  • Working well so far
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. ... show more

  • Worked perfectly right out of the box. Fast Heating and quiet as a mouse!
I love this thing. I think everyone would if they understood what is required for the installation. The two biggest things to know: Use a low pressure LP regulator. Make sure your water source has enough volume and pressure. A garden hose is fine. If you are camping you may need a different pump to run this. It must have adequate flow and pressure or the unit will not light. It's a self protection safety feature built in to the unit. Same with the regulator. Will not light with a high pressure regulator. I use this daily on the back deck to wash Moose off. (My chocolate Lab) He gets muddy and can't come inside without a quick shower. This thing is perfect and he loves the warm water. I did buy a better more durable shower head and hose for it. The one it comes with is pretty cheap, but that's ok. The unit itself is very well made and durable. I turn the water on, it starts automatically and the water is warm in a few seconds. It is faster than my own shower by far. If you have been thinking of buying one of these this is it. It makes all the hot water you would ever need for a shower and more. 5 stars, Definitely! ... show more

  • Terrible product never worked horrendous Customer service avoid at all Cost.
Size: 18L
Product came 2 weeks late and broken pilot light wouldn't stay lit tried to return they said no it's my propane pressure is to high item is fine. After litterly 2 videos and multiple requests they made it go past the return time. Item never worked and they did everything not to return and always sends a generic email. Terrible customer service and product. Cheaply made this is the second one as the first ones holding tank failed. Again my fault!!!. Change to another company and product works perfectly. No pressure or pilot light issues. Definitely would avoid buying this cheap poorly made product and terrible customer service. AVOID AT ALL Cost. Should be removed as a seller so bad. ... show more

  • Hot water no problem
Size: 8L
works well, better than the smaller capacity units. I did replace the shower head with a better more flexible hose and multiple spray options,It makes hot water quickly, only wish the display was able to change from Celsius to Fahrenheit. Maybe us Americans should just switch to Celsius like the rest of the world. ... show more

  • I would not recommend it
Size: 18L
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. ... show more

  • Hot Water On Demand!
Size: 6L
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!

  • It works, but...
Size: 10L
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! ... show more

  • I finally have hot water!!!
Size: 6L
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! ... show more
