  • Great price
Style: ES-18KW(Ver.B)
This was easy to install. It heats up fast, saves a lot of space and it was a great deal. Well made and worth the money.

  • Inconsistent Temperature
Style: ES-18KW(Ver.A)
Easy to install and adjust. However, the temperature of hot water fluctuates quite a bit. It has trouble modulating to the exact temperature and seems to vary +-5 degrees.

  • Well made, easy to install
Style: ES-9KW(Ver.A)
Update: We have been using this water heater for over a month now and are still very pleased with it. Water is always hot, and our electric bills are even much lower. We installed this to provide hot water for a one bedroom “tiny house”. It was easy for my husband to install and the included directions were simple to follow. The heater attached to the wall under the kitchen cabinet, and with the low profile it fit perfect. There is no issue running hot water in the kitchen sink, with someone in the shower. I’m thrilled with my purchase and its capacity, to provide enough hot water for our needs. ... show more

  • Best Water Heater!!!!
Style: ES-18KW(Ver.B)
I'm delighted with my water heater purchase. The fast and constant hot water has made showers more enjoyable. The easy installation was a plus, and it came at a great price point. The packaging was also well done, ensuring a smooth delivery. Highly recommended!

  • Efficient
Style: ES-9KW(Ver.A)
This tankless water heater does a great job heating the water and it is perfect for point of use. It isn’t beefy enough to run a whole house off of, but you could do a shower and possibly some bathtubs off of it. I think it is perfect for sheds, tiny homes, hunting cabins (assuming it has electric) or kitchens. It isn’t too difficult to install if you know what you’re doing and if you don’t it’s worth it to have a professional do it for you. I love that it doesn’t take up hardly any space and it is easy to set the temperature. The LED display is very easy to read and use. I think this is a huge money saver and am really happy with it. ... show more

  • Compact size, simple to use, quick heating
Style: ES-9KW(Ver.A)
Compact size, simple to use, quick heating: This item is relatively unique for this type of product thanks to its smaller, compact size, which makes it much easier to mount on a wall or put in a tight space where other water heaters wouldn't be able to fit. The product is pretty easy to operate and has a very simple, digital interface at the front of the unit that can turn the product on and off or adjust the temp. The product's heating capabilities have so far been very fast, and has been able to provide virtually instant hot water without needing to preheat at an effective rate. Overall, this is a good product and I would recommend. ... show more
