    • I thought it might be DoA like others reported
Works well enough for a sink, and only that. Nobody should be under any illusions this is meant for anything but.. When I first hooked it up, purged the air, turned on the electric and hit the power button, nothing happened. I thought it might be DoA like others reported; sure I wired it correctly as the other 120v device on the same circuit was working, I tried running some water, and boom it lit up. For some reason the power button will turn on/off when no water is flowing, but the LED display will not illuminate unless so. Live in southern California, Santa Barbara, its almost September, ground water is getting fairly cold. Heats only about 0.25GPM to "hot" ~95-100*. Thinking of replacing with the 6kw, uses the same wiring just gotta make room in my panel for another double pole breaker. ... show more

    • Unhappy customer
I purchased three of this item from Amazon. Non worked. I contacted the eco installation people, and nothing works. I decided to contact the seller no response; then amazon. They sent me around in circles, and claim they will reimburse me, but I have to fill out the email. Well, I got no email. I contacted them again, I was assured they will send the email, because the first one did not go through. Well, that also did not reach, after going over my email with them. I feel deceived and robbed. I tried call again and I keep getting routed to third world countries that can not help. I am very unhappy. ... show more

    • Nice - does the job well - great value
This is the 2nd one I've bought for my house. (The other was the 6W) They are both great units for heating the water at a kitchen sink before the hot water can make it upstairs from the basement. The only drawback is that the temperature cannot be set to a certain limit (to the best of my knowledge). It sometimes gets very hot before evening out. All adults in this household, so it's not a problem. You might want to be careful with small kids . All in all, a great value. We're happy with them. ... show more

    • Great device if you know what to expect.
The unit functions as it is supposed to and my lack of stars has to do with my own expectations. I was hoping for instant hot water. What it delivers is cool to warm to hot water depending on the rate and duration of flow. It takes about a second to come on once the spigot is open, then you need to tweak the flow of water to get it to 1. get hotter, and 2. stay on. Too slow and it turns off. And if you shut off the hot spigot for a minute or so, then turn it back on, the water that was sitting in the heating coils all that time will be VERY hot -- for a second or two -- then be replaced by cold water until the unit fires up again and starts heating. So, there is nothing wrong with this product. I was just hoping (dreaming) of endless, instant, hot water. ... show more

    • Slightly missed the mark! But overall, I'm (STILL) very happy!
Update: 12-27-2020 This unit has been used on a daily basis for 2 years now. It's installed in an RV, where either myself or others live full time... MY ORIGINAL REVIEW STANDS; this water heater has met my needs (in Central Florida) even during the coldest part of the winter. The only issue is the low flow rate required to achieve 35°F increase, but that is a factor of energy-in vs. energy-out... The limiting factor is 120 VAC, which is my choice to allow its (occasional) use on an inverter powered by solar/batteries. I would highly recommend the 230 Volt version if your installation allows for it. 12-26-2018 The unit has been installed and working fine for approximately one month. In real life, I do not see the stated temperature rise. The packaging indicates 47.8° F temperature rise at a flow rate 0.5 GPM. The lowest flow rate that this unit will allow is 0.45 GPM... Any lower flow rate and the device shuts off the heating element - apparently this is to protect from overheating. While testing at 0.45 GPM, the maximum temperature rise I have experienced was 39.6°F. In a bench test configuration the current draw was 28 amps at 122 volts (3,416 watts). Considering the flow rate was slightly below 0.5 GPM, I've concluded that this unit does not efficiently transfer energy to the water. At least not efficient enough to achieve the rated temperature rise of 47.8°F at 0.5 GPM. Although it does not quite hit the mark regarding efficiency, IT CERTAINLY FITS MY NEEDS. For that reason I'm keeping it, and in fact will likely purchase one or two more of these units. Possibly I will buy a larger unit for another location. ... show more

    • Easy install (30min) and works great!
Just installed the unit and it was super easy took only 30min if that. Made one trip to the HW store and got the right supply hoses and never needed any adapters just 1/2fip supply line and a 30amp plug. The in and out on the heater are standard water supply 1/2"NPT. I already had a 30amp circuit under the sink for the disposal so just plugged into that. Note: You need a 30amp power plug and the unit water outlets are standard 1/2" supply hose so I don't know why some reviews says it's not. The install is fast and easy if you prepare ahead of time. ... show more

I purchased the 110V 3.5kW version and installed it. At the same time, I also purchased the Ecosmart POU 3.5 Point of Use Electric Tankless Water Heater, 3.5KW@120-Volt. I installed both on the same day: one for the kitchen sink and another for a bedroom sink. The Atmor unit costs less, but it barely heats the water to lukewarm, whereas the Ecosmart unit works much better. I would recommend the Ecosmart unit because keeps heating the water for fast or slow flow rate. The Atmor units shuts down if the water flow is too high --- not a good design. ... show more

    • Complete Waste of Money
When the original stopped heating, we made the mistake of replacing with the same model for convenience. The only hot water that comes out is that which is sitting in the heating element - once that is gone, water does not heat. Complete waste of money x2
