  • Perfect Point-of-Use Heater for LIGHT USE
Installed this under my kitchen sink and it works exactly as expected. Hot water comes on quickly, which is perfect for washing dishes and everyday kitchen use. The unit is compact, doesn’t take up much space, and the digital display makes temperature adjustments easy. As a point-of-use heater, it performs well with steady water flow and has been reliable so far. Good value for a kitchen sink setup. ... show more

  • Power supply overheats rapidly
Power supply heats up hotter and faster than even well-regulated water flow does. Sure it’s an easy install, but if you have to limit water flow to a trickle and only for a few minutes before it radiates heat from the unit and crashes the system, not worth it.

  • Heater underside
Unit was average, heated water but took a long time. Therefore I can only give it three stars

  • This is not a tankless on demand hot water system
I have a one bath and this is working perfect for me as a whole house water heater. The water is almost instantly hot when I turn it on, I can't think of one reason why I would need hot water running at two different sites so I've never had an issue with it. If you seriously can't wait to run the dishwasher until after your shower, this might be better as a point of use heater. ... show more

  • Useless item.
I am about to return the item. I paid a professional to install it, and had to pay to remove it and install one that I bought from home depot which is fine. What a waste of money. This was more like a toy than a home appliance.

  • Not so great!
Doesn't seem to heat water that fast! Takes too long
