  • It's a great product
It's easy to install, and OOOJS provides two flexible hoses, one end is 1/2 inch and the other end is 3/8 inch, which are very suitable for my fittings. Because I installed it myself throughout the process, the first time I installed it incorrectly, I installed the pressure relief valve on the outlet (red end), and it flowed out slowly, while the pressure relief valve kept leaking water, obviously it was the wrong installation. The correct installation should be to install the pressure relief valve on the inlet (blue end), which works very well, it can get a lot of hot water, even I think the other 8 gallon one can be used for bathing! This 4 gallon device works very well, I set it to 125 degrees. I use instant hot water because it uses hot water pipes, if I use more than 4 gallons of water, I get heat from the main water tank. So it is a good constant source of hot water. I installed it at the hot and cold water tap at home. The dishwasher is still supplied by the main water tank. I don't want to use a 15 amp cord anymore, so I power it with the dishwasher plug. I bought an in-line expansion switch with a rated load. The tank can keep hot water for a long time, it only takes 10 minutes to heat up. It's a perfect solution, it's small and easy to install. No more cold water in winter to wash hands, no more wasting hot water. ... show more

  • Good Value For The Price
Color: 8.0Gallon
The 8 gallon hot water heater works well and it was easy to install. The water gets very hot and I find that although it’s small and compact, I can take a 10 or 12 minute shower before the hot water runs out and it only takes a few minutes for the water to heat up again. I use it in a tiny house where there is about a 12’ distance from the bathroom where the hot water heater is installed to where the kitchen sink is located. The kitchen water is just as hot as the water in the bathroom and I’m very satisfied with my purchase. ... show more

  • Don’t buy! Don’t buy!
Color: 8.0Gallon
This seemed like a great product. In fact several months after I purchased it I was so impressed that I bought a second one. I bought this first item 6 months ago but it failed. The heating element went bad and you can not get a new element anywhere. I now have to toss it and go buy a new one somewhere else. I see distributors of this brand that advertise a 1 year warranty however you get no such warranty with an Amazon purchase. Save your time and money and buy a serviceable water heater! This product will cost you over $20 a month for the short 6 months it will work not including installation and aggravation and I believe this makes this heater very very expensive. ... show more

  • Would highly recommend
Color: 8.0Gallon
Would have never purchased this if I didn’t already have one in the camper we purchased used. It seriously looks like an easy bake oven but don’t be fooled. This little water heater never lets me down. I can wash a load of laundry take a shower do dishes and then my spouse can shower and always have hot water. You can’t turn it up all the way or it’s way too hot! I would highly recommend this little guy. Our first one stopped working as I turned the water off and forgot to unplug it. Was super easy to replace. Literally two hoses you put on and plug it in. ... show more

  • Inline water heater Inline water heater
Directions seem confusing to me. But I'm not a plumber. Did get it installed and it seems to work. There is what looks like a red light on the front. I assumed that it was the power on light. But it does nothing and I don't see anything in the directions about it. So I turned up the control knob all the way and waited a few hours. Got instant hot water, very hot. The kitchen sink is the furthest away from the main water heater, so it would take at least 5 minutes to get warm water. So far so good. Update 1/29/25. Stopped working. Instructions say there is a reset button behind front panel, can't find one. I would say stay away. ... show more
