Time to get rid of those "lukewarm" toys.
  • SMART SELF ADJUSTMENTThe hot water heater adjusts power input based on flow rate and temp setting in real-time. For example, less power will be applied by the system when water flow is reduced, thus you still get the ideal temperature instead of scalding hot water, which means a comfortable experience. An optimal energy efficiency of 98% saves considerable electric charge.
  • CONVENIENT USEThe tankless water heater comes with a digital display and touch control panel so the temperature setting is easy job. Now turn on the tap and let the smart unit do the rest, you neednt go through a hard lesson about temp setting by a mixer tap without any hint.
  • SAFE and DURABLEApplied with multiple protection devices, every piece goes through strict tests to ensure 100% safety. Inner water and electricity lines are designed to run separately to avoid leakage or harm from scale build-up.
  • POINT of USEThe sleek tankless water heater is as compact as an oatmeal box, making it possible to install it anywhere close to the outlet and avoid energy waste. It can be mounted horizontally, vertically, and obliquely, ideal for kitchens, bars, schools, hospitals, communities, and hair salons.

  • Surprisingly powerful
Style: 4.5 kW
I should have paid attention to the 4.5kw aspect of this heater. It really puts out a lot of really hot water. So much so that its too powerful for just one sink. You can adjust the temp but this could clearly run a shower as well as multiple sinks. Easy to install.

  • Can be used other than in a RV
Style: 11 kW
The media could not be loaded. When we found this tankless hot water heater, it was advertised as one that goes in an RV. We installed in our office and love it!! It was placed under the sink in the cabinet and has served us well. We don’t use a lot of hot water but when making bottles for baby calves it’s heaven sent!! Great purchase!!! ... show more

  • great value
Style: 9 kW
nicely made, priced right! Good value heater... the unit install easy, simple operation, plug n play if you have a 240/40amp dedicated circuit if not, forget it.... if you need to run a circuit, its costly and be sure you have enough capacity... then, this is not for a big house to replace a large capacity HW heater be sure it will work with your flow needs and temp splits, as if you have very cold water entering the unit, it will produced lower temp hot water at higher volumes...so do some homework to pick right... easy plumbing in n out, safety features built in, so far, so good, no complaints 4.5 stars ... show more

  • Very Stylish, Easy To Install, Some Concerns
Style: 9 kW
When this item popped up in my feed, I thought it was made by the “major brand”, but after looking again, I had to laugh at how similar the names are. That does raise a few caution flags, but not a deal breaker. If just going by looks... this is a very attractive and stylish looking product. There is one major omission on the product page. There are four different sizes of this heater, and nowhere does it state how much water flow each unit will heat or what applications can be operated from each of the units. Will it heat the entire house? Will it run just one bathroom? Or just the kitchen? Or just the laundry room? That is something a buyer must know before ordering. The booklet included with the heater does have a chart showing the maximum number of degrees the heater can raise the incoming water at different flow rates. If you want 125 degrees, which is standard for most tank-style water heaters, then this 9kw unit might handle a single bathroom or the kitchen. Another issue of concern is this unit is not UL listed. Whenever I install electrical devices in my home, especially high-power devices, I look for that UL label. Because of all of the above, I decided to use this in a half-bath in my new workshop and not in my home. I had already dropped a 240v/40 amp circuit to the bath during construction... and of course, the plumbing was in place... so installation was simple. Operation is also easy. ... show more

  • Great buy for the money
Style: 9 kW
So far a great water heater, works great for small spaces like the master bathroom and or a small mobile camper. Contains minimal feedback on water flow, and instant hot water on tap and stays constant. Easy to install and place in a confined space. Overall a great water heater, great when used as a backup. ... show more

  • Hot water, fast
Style: 9 kW
I recently had a boiler bite the dust, and so I knew I wanted to upgrade to a tankless water heating system. This one arrived just in time, and I was able to swap out the old boiler with this new setup. This heater is sufficient for my needs, since there are only two of us living in the house, and we don't use hot water very much since we live in a state and an area that is pretty much hot all the time. However, I have noticed that the hot water gets through the pipes a little bit faster, and it doesn't really run out like it would with the boiler. I am completely satisfied with this water heater, and I knew I would go this route ever since some of my other family members showed me the light with their own tankless system. 10/10 ... show more
