  • Hot Water on the Go
The media could not be loaded. This neat lil powerful instant electric tankless water heater offers a convenient and efficient solution for heating water in various settings (think long road trips and camping). From home kitchens to RVs and bathrooms, this water heater ensures a constant temperature for hot water while providing self-modulating functionality. One of the standout features of this tankless water heater is its 360° installation capability. This means that users have the flexibility to install it in any orientation, allowing for easier integration into existing plumbing systems. Whether you prefer vertical or horizontal installation, this water heater can accommodate your needs. The touch digital display is another notable feature that enhances the user experience. With its easy-to-use interface, you can conveniently adjust the temperature settings and monitor the water heater's performance. The digital display provides clear and accurate information, ensuring that you have full control over the water temperature. As a cool bonus, the self-modulating technology of this water heater allows it to adjust the power output based on the actual water flow rate and temperature (waste not want not). This not only ensures consistent hot water, but also helps to save energy by only using the necessary power. Best feature - You can enjoy hot water on demand without worrying about excessive energy consumption. ... show more

  • Easy install but, won't heat.

Piece of crap. Barely makes off cold water.

  • Seems to work, but not sure for how long?
Item Shape: Rectangle
This hot water heater seems to work for lower flows. It did not like trying to keep up with a 1.2 gpm faucet. It was warmer but was giving the ll error saying it couldn't keep up. Seems like it could keep up well with a .5 or .75 gpm faucet. During the summer this actually might produce hot water at a decent flow. In the winter it makes water very warm, slow the flow and it will get it hot. For $60 it's an amazing deal if it lasts for a while. It doesn't make any noise and can be set to a specific temperature and will tell you the current outlet temperature also. I'm skeptical of the 5500 watt claim since it says it can use 12ga wire, I need to put an amp meter on it. Does not trip a 20amp breaker. For those that keep having leaks or breaking the inlet and outlet, you are using the wrong type of connectors, these are designed to use the flexible hoses that go on sinks that have the rubber washer inside, this can't use threaded pipe sealer with sealer, just too thin and not designed for that. Others that can't get any heat have the flow backwards, there is a flow switch that won't work if it's backwards. ... show more

  • Junk to Gold
Item Shape: Rectangle
So initially as soon as I received this I put it in the pile to return to Amazon. But then after we figured out the electrical connections were very pleased. Here's the situation: our home hot water heater kicked the bucket for the last time, and I want to take this opportunity to upgrade a lot about our system (like increase copper pipe diameter, add multiple water filters, recirculating pump, and add a tankless + tank combination). So we are going to be without hot water for showers for two or so weeks. I initially bought a 110V system which has worked to remove the chill (heating up to about 32C) from the water at low flows, but if we turned up the water flow or the temp setting then we'd inevitably trip a 20Amp circuit breaker. That's why I bought this 220V system, I thought I could use it with the unused 30Amp 220V dryer outlet. However, that outlet was Red, Black, and White (neutral), not grounded. I removed the outlet (after shutting off power), saw that we had ground wire connected to the metal electrical box, and then did the following: Changed to a US 220V 3 prong grounded outlet as pictured, using Ground, Red, and Black. Added the matching 3 prong plug to the wiring of this water heater. Then I ran an10/3 (10 gauge, 3 wire) extension cord usually used for RVs to water heater, et voila, it works! It gets as hot as we need the flow is much stronger than with the prior 110V unit, certainly enough for showers. Note that I did turn down the water flow with the little adjustment screw by the hot water connection to guard against excessive electrical usage. ... show more

  • Neat, but doesn't get very hot for 220v
Install was easy enough, but this thing just doesn't get hot like I wanted. It will get warm at best & that's with the flow restricted severely. Instant "hot" water heater running 220v you would assume could get hot to the touch, not this little guy. If you want to get warm water, it will be fine, but if you want it hot like I do, this thing won't get the job done. ... show more

Works perfectly!! Heats in seconds and maintains the temp the length of your shower time. Am not sure of durability or lasting time frame. Have used it about 18 months. So far, very satisfied.
