This electric water heater has surprised me with its operation and size. It heats the water very quickly and keeps the temperature stable thanks to the digital screen that allows you to see it clearly. It is compact, easy to install and perfect for sinks, kitchens or small spaces. It does not make noise and consumption is low for the performance it offers. Ideal for those who need immediate hot water without taking up much space. ... show more

  • Great heater for the money
Style: 3000W 110V
This heater arrived and was identical in size, appearance, and function to the previous heater, except it's digital now, so hookup was quite simple. The led displays are fairly bright, and it's simple to select the desired temperature.

  • Nicely made unit
Style: 5000W 110V

  • Convenient Compact Heater with Some Limits
Style: 5000W 110V
I’ve been using this 110V, 5000W tankless water heater under my kitchen sink, and it does exactly what I hoped—provides hot water on demand without taking up much space. The compact design is a real advantage if you don’t have room for a bulky tank. Installation was manageable, though I’d recommend having some plumbing experience or a professional for best results. The digital display is clear, and I like that it allows switching between Fahrenheit and Celsius. The included remote control is a thoughtful touch—it makes adjusting the temperature easy without bending under the sink. Once set, the unit maintains a steady output, and for handwashing or light kitchen use, it heats water quickly and consistently. That said, it’s important to know its limitations. At 5000W on 110V, this heater isn’t meant for heavy-duty whole-house use. The flow rate is modest, and if you expect long showers or multiple fixtures running at once, you may find it underpowered. It works best for a single sink or small applications. Bottom line: A practical and space-saving solution for quick hot water in one location. As long as you understand it’s not designed for high-demand use, it’s a reliable and efficient little unit. ... show more

  • Works great for instant hot water!
Style: 5000W 110V
This little tankless water heater is very convenient. I installed it under my sink and it gives hot water quickly without having to wait. The temperature control is easy to use, and I like that I can switch between Fahrenheit and Celsius. The remote control is a nice bonus, and it’s perfect for small spaces where a big heater won’t fit. It heats up fast and is very efficient for daily use. So far, I’m very happy with this purchase! ... show more
