I recently installed this 120V, 1500W Electric Water Heater, and it’s been a wonderful for my home. This water heater provides a good supply of hot water whenever I need it. It takes up very little space, making it ideal for apartments or homes where space is at a premium. I have plenty of hot water for our kitchen sink, which seems miles from our gas water heater. I ran the hot water supply into the cold input of the this water heater, then out to the hot water side of the faucet. It works out excellently. Ease of use is key. The controls are intuitive, so there’s no real learning curve. Installation was straightforward as well. The instructions were clear, and I had it set up and running in no time. It’s designed for 120V. I’m a licensed electrician so I installed power myself. However, you will likely want to hire an electrician to ensure everything is properly grounded and bonded. This water heater has surpassed my expectations. I never run out of hot water. It’s also energy-efficient, which has already started to reflect positively on my utility bills. The consistent water temperature and reliable performance make it a great choice. Overall, this Water Heater is a fantastic investment. It’s compact, easy to use, and delivers exceptional performance. I highly recommend it! Great seller, awesome product, and fast shipping!!

This is the second in-line water heater we have ordered. I installed the first one under our kitchen sink which is a double wide cabinet with plenty of space. So when I ordered this unit for our guest bathroom, I didn't even think about checking the amount of space in our under sink cabinet. Big mistake. The Kenuos heater would not fit because of the small cabinet size and the sink drain which came down right in the middle of the cabinet. So in order to install the heater I had to totally redo the sink drain using an offset drain pipe made for these particular types of problems. I also had to fish wiring through the walls to get electricity to the heater. The final installation is shown in the photo. It turned out to be a much larger and more complicated job than the kitchen installation had been and I urge you to measure, measure, measure to be sure you have adequate space (over one cubic foot - heater measurements are shown in the produce description). The other small issue I had with the Kenuos heater is that while they do include flexible water connection hoses with the unit, only one of them has the correct fittings. The correct hose has a 3/8 compression fitting on one end (to attach to your shut off valve) and an NPT fitting on the other end (to connect to the input port of the heater). The other hose is exactly the same. But the second hose has to go from the output port of the heater (which is fine) and the other end connects to the hot water faucet inlet which is almost always a 1/2" NPT or MIP fitting. But the hose included in the kit is a 3/8" compression fitting. I was fortunate to have an adapter in my clutter of old plumbing parts but you will probably have to head out to a hardware store to find either an adapter or a different hose to connect up to your sink faucet. I suppose this isn't a huge issue since most installations are going to be a bit unique and you might assume you will need to buy a few extra parts and pieces to get things hooked up. Once installed, however, the Kenuos heater has functioned quite well and all-in-all was worth the extra effort needed to do get things to fit. But be warned, installation may not be for the amateur DIYer and you may want to bring in a pro...as is suggested in the product description.

Got this to use with our portable dishwasher. We installed a separate faucet even for the dishwasher before and now this is under the sink for it. It will supply all the water we need for the dishwasher and it is very effective. Compact in size approximately a foot by a foot. I can foresee a savings on not only water (the big tank won't have to fill plus gas used to heat it) and being energy efficient, that's value for your money right there and then some. We installed ourselves or should give a shout out to the hubby that installed it at his 71 years old. Said went smoothly so I'm going with that. I recommend this for your hot water kitchen needs.

This small water heater is quite practical, especially suitable for places like kitchens or bathrooms where you don't need to worry about the amount of water, but you want to have hot water at any time. The 4-gallon capacity is just right, enough for washing dishes or simple hand washing. The hot water comes quickly, and the 1500W power heating speed is not bad. You can have hot water in about ten minutes. The installation is relatively simple, with a 1/2" NPT interface, and there is no trouble to install it yourself. It is small in size and can be easily stuffed under the sink without taking up space.

This awesome little water heater is going to be the centerpiece of an outdoor shower I am building. I needed a small electric water heater with temperature control to add to my setup so I wouldn't be taking cold showers all the time. I do have to get some different adapters to hook up my hose line and I am going to offset the placement so it isn't right in the path of falling water, but I really like all the features and the build quality. This will be used outside, which I am a little worried about, but it will be under a porch, so I think it should be ok. I did plug it in to make sure it worked and no initial issues were noted. If you are hooking this up to a sink, all of the included hoses should fit and you shouldn't need anything else. If you are using it for something like my application, you will have to get adapters to run from your garden hose to the inlet and them the outlet to the valve the controls your shower. That is the part I am stuck on now. Will update when she is fully up and running, but so far so good with this setup.

The unit seemed used and was missing some parts. I didn’t want to install a used one so I returned it.
