  • Instant Hot water
It heats up water super fast and keeps it steady, which is perfect for under the sink. The remote control makes it really easy to adjust the temperature, and switching between Fahrenheit and Celsius is a nice touch. Definitely a handy little upgrade.

  • Defective..
Once installed (with the Expense of tubing, etc.) The Unit Blows the Breaker??

  • Convenient Compact Heater with Some Limits
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

  • Needs lots of power
The concept and size of this heater are great but beware that the power needed might not be suitable for most US households. The largest residential wiring is typically 20amp and this required a 60 amp breaker, which would burn up the 20amp wiring before popping the breaker.
