  • COMPACT AND EFFECTIVE, BUT WITH A FEW LIMITATIONS
Style: 2.5 Gallon-Black without Led Display
CONVENIENT SIZE FOR UNDER SINK USE The KENUOS 2.5 Gallon Instant Hot Water Heater is designed to fit easily under the sink, and it truly delivers on that front. Its compact size is perfect for small spaces – I installed it in my kitchen, and it fit neatly without taking up much room. For anyone looking to get hot water quickly without needing a full-size heater, this mini tank is a practical solution. QUICK HEATING BUT LIMITED CAPACITY With a 1500W heating element, this water heater gets the water hot pretty quickly. Within minutes, I had piping hot water available, which is impressive for its size. However, with a 2.5-gallon capacity, it’s best suited for smaller tasks, like washing dishes or rinsing produce. For extended hot water use, like filling up a larger sink or running continuously, it may run out of hot water quickly and need a bit of time to reheat. EASY INSTALLATION Installation was straightforward, and the 110V power makes it accessible for most home setups. I had everything up and running in under an hour, and it didn’t require any special tools or additional fittings beyond the basics. This makes it a great choice for a DIY installation if you’re comfortable with some basic plumbing. PERFORMANCE & EFFICIENCY For smaller applications, it performs well, delivering consistent hot water on demand. It maintains a steady temperature, and I didn’t notice any significant fluctuations while using it. However, it’s worth noting that because it’s on the smaller side, the 2.5-gallon tank is limited in terms of sustained hot water supply. VALUE FOR MONEY For the price, the KENUOS Mini Tank Water Heater is a solid choice. It’s budget-friendly, and if you’re looking for a quick, efficient hot water source under the sink, it does the job without breaking the bank. But if you have higher hot water demands, you might find the capacity a bit lacking. FINAL VERDICT Overall, the KENUOS 2.5 Gallon Instant Hot Water Heater is a compact and efficient option for point-of-use hot water in smaller areas. It’s quick, easy to install, and a great solution for small households or light kitchen tasks. Just keep in mind its limited capacity if you need a larger supply of hot water. For the price, it’s a worthwhile investment that performs well within its intended use. ... show more

  • Time will tell
Style: 2.5 Gallon-Black without Led Display
Warms up fast but the relief valve is directional and you’re going to look at arrow on valve and install accordingly , you will need fitting also that is not included to install correctly ! I’m hoping this lasts a few years. Wonder why but it’s from across the pond.

  • Awful investment
Style: 2.5 Gallon-White without Led Display
The media could not be loaded. Bought the water heater in December 2023 and installed it for my studio to have instant hot water to my sink. Seemed a like pretty good deal. At first... It was a pain to install. Constantly leaked from the pressure release valve and then finally started leaking from the front face plate (video included). Photos show the corrosion that happened in literally less than 3 months. The fact that none of the electrical is protected from water meant that this water heater was a ticking time bomb. An absolute trash piece of work. We only figured out the problem after we took apart the entire water heater. Don't waste your time with this product. You can't even replace anodizing rod which is highly recommended in other water heater brands. We switched to Bosch because I'm absolutely floored with how poor this product was made. Everything about it has been a friggin nightmare. ... show more

  • Tank works as promised.
Style: 2.5 Gallon-White without Led Display
Everything works fine. Tank came with two hoses for sink hook-up. One has the gasket/washer and the other one was MISSING this part. See photo. Using old hoses for now. I would appreciate getting a gasket washer for the hose.

  • Not that great
Bought this unit because our house has a tankless water heater with a water distribution system that takes several minutes to get hot water to the sink. This was supposed to solve that problem. It's a relatively large unit (larger than some competitors' products) and so it was a bit of a chore to install. Once installed, it is working, but not quite as smoothly as we want. On several occasions, it kicked on and tripped the circuit breaker for that part of the house. At other times, the water temperature seemed to fluctuate a lot - sometimes too hot, and sometimes too cold. Several other people in our neighborhood have the same problem and they adopted our solution, but we advised them to get a different manufacturer's product that does the same thing. ... show more

  • Very nice hot water heater. Update
Style: 2.5 Gallon-White without Led Display
Update: This heater was absolutely awesome, and about a week after the year mark, it just stopped working. Too bad actually because it was really great when it was working. I live in a mini-house and needed something small to put under my kitchen sink so I would be able to wash dishes, etc. This was perfect. I got the 2-1/2 gallon tank. It set up fairly easily with 1/2 inch Pex, but I think it definitely helps to have some knowledge/skill in plumbing. The unit plugs in and has quite a short cord, but that was easily factored in for me. Did have a small leak on the hot side when I turned the water on for the first time, but a garden hose gasket that I had on hand fixed it easily. I liked the size and the price of this, shipped quickly and packed well. It fit easily under my sink as it is less than 12 inches square. The really great part is how well it works. It takes mere minutes to heat water. This is not an on-demand system, but a point of use; however, I was doing a large project in the kitchen and house today, cleaning a lot of things, and I never once ran out of hot water because it heated up so quickly in between uses. It's so handy that we purchased two more, one for my parents kitchen sink, and another for the laundry room. For the price, you can't beat it. ... show more
