Not impressed. Takes water from 54 degrees to 70 running water slow or fast. Bought for a sink in the shop to wash hands. Cord gets warm to the touch after a few minutes Had to install a 30 amp breaker to run it.

The compact design of this tankless hot water heater makes it perfect for smaller spaces! Installing this tankless hotwater heater is a relatively straightforward process. It is easy to install, and no special wiring or plumbing skills are needed. It easily mounts on the wall or under the cabinet if you have room, and fits perfectly without taking up too much space. The tankless water heater is easy to maintain and is a great value. The digital display is clear and helpful, but I LOVE that it is energy-efficient and ready at a moment's notice. I wouldn’t want to try to use it for a cup of tea, though, because the max temperature says 109-131 degrees Fahrenheit. I’ve yet to find any instructions on how to turn the temperature up, either, so that’s a big downfall in my opinion. Coincidentally, I wouldn’t try to take shower using this tankless heater either. Would I order it again? No, I definitely wouldn’t make the purchase again, just because of the shower and not being able to adjust the temperature.

We picked this up for our trailer conversion, and it’s been a great addition so far. For such a small unit, it heats water quickly and reliably, which is exactly what we needed in a tight space. The digital display is easy to read, the setup wasn’t complicated, and it fits perfectly under the sink without taking up valuable room. It’s not meant for long, luxurious showers, but for washing hands, dishes, and quick clean-ups, it delivers just what it promises. If you’re doing a trailer, RV, or any small-space build, this is a handy little heater that gets the job done.

I had a professional install the DOYXC Tankless Water Heater Electric 110V, 3000W 5 days ago. It has popped the 20amp CB 6 times. After the first 2 events, we went in the test mode. It seems that if the hot water is used for a few minutes, then used again about 1 hr later for a few minutes, the unit will trip the 20Am CB before a 4th try. This has happened the next 4 test cycles. It is on a dedicated line. It must be defective or a piece of junk. In addition, if the water is turned on fast, it can only heat the water to a not very warm water. If you turn it on very slowly, it can get the water pretty hot but not so hot that you have to stop having you had under it. DO NOT BUY THIS UNIT.

I liked the idea of this water heater for quicker hot water in our kitchen. But the threads on one side wasn’t threaded right for the connection to be successful. It also wouldn’t turn on for more than a few seconds. Unsure if that is a defect or if bc on side leaked maybe was an auto shut off. Can’t say. We might order another for a 2nd try but unsure just yet. Was a great price compared to others we seen.

Very practical and easy to use. We installed it under the sink and it heats the water instantly, without any waiting. The size is perfect and it takes up hardly any space. The digital display is very useful for seeing the temperature. Ideal for the kitchen or bathroom, it saves energy and does its job perfectly. I highly recommend it for home use.
