Review: Understang how these water heaters work - I started looking into tankless water heaters a few years ago when I started to have problems with my tank water heater. I replaced the thermostats and all was well but I noticed a leak and knew it was a matter of time before I would have to replace it. I found this model on desertcart and it appeared to have some good reviews and a few not so good reviews. So I took the plunge and acquired the heater. There are some facts that aren't in the description as exactly how this device works. Sure, they give you charts on water temps for different areas of the country, flow rates for the heater, ect. I live in Tennessee and right now ( November ) the cold water temperature is 53 degrees. After installing the heater I set the temp on the controller to 110 degrees, turned on the hot water faucet in the bathroom, and it barely got warm. Somewhat disappointing, I reset the temp to 120 degrees on the controller and it got slightly warmer. So I got to looking at the chart again realizing that probably the water temperature of 53 degrees was too cold for the heater to operate efficiently. The was a solution to my problem, in my case we have a small home, one bath and the normal bathroom sink and a sink in the kitchen, was controlling the inlet cold water volume to the water heater. I reduced the water volume to about 2.5 gallons per minute, set the controller temp on the heater to 120 degrees F. Now the water temp out of the faucets approached 118 degrees. Mixing in cold water I can enjoy endless hot water in the shower, that is hot. Another small anomaly is turning off hot water for a small amount of time will cause the heater to stop heating and it will introduce cold water in the outlet until it heats the water again. So if you turn off the hot water in your shower, ect., you will feel the chill for a few seconds..... This is a great heater and was fairly easy to install. Installing the #6 wire was the hardest part. I recommend this heater if you have a small home. It works well and I am very pleased with it. -BoBc
Review: Works great for a family of 5 - 4 month update- still works great! Never really noticed a difference in my electric bill like some people claim, but overall I’m still pleased with this purchase. I noticed some people saying it doesn’t last longer than 6-12 months. Hopefully that won’t be the case with mine. I will do another update around the 12th month mark to let you know how it is still working. We can have someone in the shower, dishwasher running, and clothes washer running all at the same time with no issues. We have also had both our showers going at the same time and still had no issues with a lack of hot water. Water heats up REALLY hot if set to the highest temperature. The best part of a tankless water heater.... we can all take showers back to back without ever running out of hot water. Not too mention, tankless is just simply more sanitary then those nasty tanks! Hook up was simple. I went to Home Depot and they helped with everything. I used shark bite adapters which made connecting all the pipes a breeze. I was worried about getting it and not being able to install it myself, but it truly was easy. I'm very pleased with my purchase and would definitely recommend it to everyone I know.

### ⭐ ONLY LASTS ABOUT 2 YEARS no matter if you change the filters or not.
*by V***R on October 22, 2025*

This product works great for about 2 years whether you change the filter or not. Then it dies. This is the third time I have bought this item and the first one lasted about 2 years and I never changed the filter that often so I thought it was my fault. So I bought another one (second one) and changed the filters regularly and it just quit after a little over 2 years. I bought a third one just now because it is easy for my friend to just take the old one out and put the new one in. But I will be switching to something else when this one dies in 2 years to something that lasts a little longer.
