  • Small but mighty!
Style: 6.5KW White
I saw the dimensions in the listing but have to admit I couldn't beleive quite how small this is until I got it. The 6.5kw heater (note it's 240v, the other models are 120v) is about the size of a cereal box..so easily something you could mount under a cabinet. My use case is for outdoor cleaning, so I appreciate that it's waterproof (splash-proof not drop it in the pool waterproof). It comes with a 2-3ft pigtail wire that you can either attach a plug or wire into a box... But note if you need a longer wire, I don't see an easy way to remove the pigtail and install your own wires directly. The outlets are 1/2" NPT so I had to add adapters to attach a garden hose but easily able to find those at my local hardware store. Additionally it comes with a bracket for mounting to the wall. Once water was hooked up and you power it on, it wastes no time getting to business heating water. The digital display tells you the current temperature of the heated water and you can adjust it to as low a 86 degrees fahrenheit. The unit is perfectly quiet and didn't get warm to the touch after running for more than 10 minutes. All around a great item that works well. The included instructions were straightforward and easy to follow. ... show more

  • Great little heater
Style: 6.5KW White
This model is a 240v electric water heater so make sure you consider that when purchasing. We have a small mobile home that had a tank water heater. We wanted to remove it so that we had more space in the closet and this worked perfectly. We had to convert from 120v to 240v but that was the hardest part of this small remodel. The water heater is really just a 'plug and play'. Once you have it hooked up you have hot water on demand almost immediately. This is the perfect size for our small mobile home. ... show more

  • Efficient, Space-Saving, and Reliable Instant Hot Water Solution!
Style: 6.5KW White
The Tankless Water Heater Electric has been a fantastic addition to my home! It was delivered safely and packaged well, and installation was straightforward. The sleek design fits perfectly in smaller spaces, and the LED display is easy to read and control. I love that I can switch between Fahrenheit and Celsius, which makes it super convenient for everyone in the house. What really impressed me is how quickly it provides on-demand hot water. Whether I’m showering or washing dishes, I never have to wait for the water to heat up. Even during peak usage, the water temperature remains consistent, thanks to its automatic control system. The 6.5KW power is more than enough for my home, and I appreciate the energy efficiency as well. The fault self-test feature is a nice touch, giving me peace of mind by alerting me to any potential issues. Overall, this tankless water heater has exceeded my expectations with its performance, compact design, and ease of use. If you’re looking to upgrade your water heating system, I highly recommend this one! ... show more

  • 110v or 240v?
Style: 6.5KW White
I based my decision to order this product on the written product description that says 110v. However, it's a 240v unit which, I did find was listed on one of the product photos, but only once it arrived.

  • Point of use water heater
Style: 6.5KW White
No more running out of hot water! I had a friend with electrical and plumbing experience help with installing this, and even though it felt complicated to me, he said it was actually really easy. (I'm taking his word on that.) All I know is that there's fifty feet of pipe between the big household water heater and the kitchen sink. That means that before installing this it took forever for the water coming out of the tap to heat up, but not anymore. For years this has meant wasted water and wasted electricity, so adding this point of use water heater to the kitchen is saving me time, and water/money. Now I'm thinking about adding one to the master bath because the idea of endless hot water for the shower feels like a luxury I should be embracing. The installation was easy (or so I've been assured), the unit itself is very compact and fits nicely in the cabinet underneath the sink without mee feeling like I'm losing usable space, the controls are easy to read and adjust, and the unit is very responsive, giving me endless hot water for doing dishes, cleaning, etc. ... show more
