Generic Tankless Water Heater Electric, Instant Hot Water Heater Under Sink, 3000W 110V On Demand Mini Water Heater for RV Kitchen Bathroom, White

This heater takes up a very small footprint. It does a good job of quickly heating the water within a few seconds. However, you need to know a few things before ordering it. Per the item description, it works best with a limited flow faucet. The water gets quite hot with a 0.5CFM faucet, just barely warm enough for a shower with a 1.0CFM faucet, and does a good job of taking off the chill with a 1.5CFM faucet. Its rated at 3000watts (25Amps) of electrical power. My home is fairly new construction and has a 20Amp circuit breaker for the bathroom. The heater drew 2600Watts (22Amps) for 30 seconds and then the circuit breaker popped. You will need a 25-30Amp breaker to power this heater.

Requires a dedicated outlet to prevent breaker from tripping, running for more than a few minutes can sometimes trip the dedicated breaker as well. Purchased in February, finally got in installed by mid June. It just stopped working in November. To get the water more than just warm water flow has to be low, barely enough to wash your hands. Used in work shop and was able to get the pressure where it worked for me. While it was working I gave it a 3 or 4, but since it worked barely 6 months it gets the one star it deserves

I don't know why never explain how their devices work, but here it is. The operation is pretty simple. You set the temperature by regulating the flow of water. The device has various protections, but it always operates at maximum power, so to increase the temperature you need to reduce the flow. Keep it away from water or steam as the electronics inside are not waterproofed whatsoever.

We installed this unit as per recommendations on the instruction sheet. At first the hot water was pulsating hot and cold, we tried to lower the water pressure to the unit to increase the temperature as per the directions. Once we lowered the water pressure reaching the unit the water heater would not turn on at all, we finally were able to reach a water pressure level where the water would no longer pulsating hot and cold but had very low volume.

Used this as a last resort after buying 5 different water heaters on amazon that arrived defective. This machine heats up water up to 130 degrees although it states in the description that it will heat up to 120 Which is a plus for me! The machine is simple to use and heats up water quickly!

I did not like it. I never got anything but slightly warm water. I tried to use it in my camper. I don’t know if it was just too small for my camper. I think it was more for just like a sink for handwashing or something like that.

I was skeptical after reading the reviews. Here is my experience after installing it. After installing it and assuring there was no air in it, I plugged it in. Immediately, the display started a rotating circle of blue light. I tried pushing the on off button but nothing happened. Then I tried running the hot water. The rotation stopped and it displayed the temperature and heated up very quickly. Please note that I am using it on a line that is hooked up to my main water heater. The water got up to 130 degrees. I assume that must be its limit. I have my main hot water heater set at 120 so it heated up above it. It seems to only get that hot after running a couple of minutes. I am finding now, that when I first turn on the hot water, it gets warm and then gradually heats up, until the water from my hot water heater hits it, then it goes to 130. My wife loves it. Before installing it, she had to run the water for several minutes to get hot water!

Perfect price, works fantastic in a camper, the hot water is diffentily hot with hot water on demand ,, doesn't require much space at all. Would order again for other projects. Thank you.
