  • Very Well Made!
The KENUOS 2.5 Gallon Mini Tank Water Heater is designed for providing hot water in about 5 to 8 minutes in compact spaces, making it suitable for under-sink installations in kitchens, RVs, and other applications. Here’s a review based on its features and user feedback: Pros: Instant Hot Water: With a 1500W heating element, this mini tank water heater provides hot water within a few minutes, which is ideal for quick tasks like washing dishes or handwashing. Compact Design: The 2.5-gallon capacity and compact design make it easy to install under sinks or in tight spaces, making it a great option for small kitchens, RVs, or areas where space is limited. Easy Installation: Many users find the installation process straightforward, especially with the included 1/2" NPT fittings. The unit can be wall or floor-mounted, providing flexibility in installation options. Temperature and Pressure Relief (T&P) Valve: The inclusion of a T&P valve enhances safety by preventing excessive pressure buildup, which is an important feature for any water heating system. Energy Efficient: The mini tank design allows for heating only the water you need, which can be more energy-efficient compared to larger traditional water heaters, especially in smaller households or for specific applications. Cons: Limited Capacity: While 2.5 gallons is sufficient for small tasks, it will not be enough for larger needs, such as filling a bathtub or providing hot water for multiple simultaneous uses. Users should consider their hot water demands before purchasing. Recovery Time: Some users have noted that the recovery time can be longer than expected, especially when the tank is depleted. This may require careful planning for tasks that need a continuous supply of hot water. A watched pot never boils! Noise Level: A few users have reported that the unit can be somewhat noisy during operation, which may be a consideration for those sensitive to sound or for installations in quiet environments. Temperature Control: The temperature settings may not be as precise as some users would like, and the unit may not reach very high temperatures, which could be a limitation for certain applications. Conclusion: The KENUOS 2.5 Gallon Mini Tank Water Heater is a practical solution for those needing hot water in compact spaces. With its efficient heating, easy installation, and safety features, it offers good value for small kitchens, RVs, and other applications. However, potential buyers should be mindful of its limited capacity and recovery time to ensure it meets their specific hot water needs. Overall, it is a reliable choice for enhancing convenience in hot water access. ... show more

  • Compact/Effective/Simple
This is neat if you need something like this. I ordered it out of sheer curiosity and I don't know exactly how it will fit into my life except in case of emergency. Maybe if you like to camp, and own a camper without a water heater, if you run a generator or pay for hook ups, it can be useful. Not hook ups like that!! Although you may want to use some hot water then, too. LOL It was easy to ready, despite the oddball pamphlet which came with the unit. I took the time to scan it for your perusal in case it might assist you in your decision to order. It is pretty straightforward with a cold water inlet, a hot water outlet, a Temp/Pressure valve and a nice LED display. They included some teflon tape and a tee connector, which is optional on either the hot or cold lines. They did send along two 1/4" supply lines as well. It is very lightweight so portability is not an issue for the aforementioned possibilities. By the way, when I installed the t/p valve, it took some force to get it to seat vertically but it got there. Not real excessive force but more than I would have applied on something that didn't need to be aligned such as this. The tube for T/P release is a nice touch as well. LOL In closing, I think that if you are in need of something like this, you will enjoy this unit. Helpful? I hope so✔️ Thanks! ... show more

  • Good mini point of use water heater!
This is a good little water heater. It's a point of use system, meaning it has to be in the room you are using the hot water, as it does not make that much. It's 120v powered so that should tell anyone that the water it makes is slow, 1 or maybe 2 fixtures depending on outside weather. I got this for an adu that has a bathroom. The install was very easy, hook in cold water, and add the hot water pipe to the fixture you need it. The adu has a small bathroom, and right next to it is a kitchenette. This is able to supple hot water to both, provided only one is being used at a time. I like the fact that it has a tpr valve for added safety. It's set to max hot water, it provides a decent 5 min shower if you have it set to warm. This was installed in California, so it should provide decent warm/hot water year around. If you are installing in a very cold climate where it gets to 20F or below, it may struggle in winter months. Its not for suppling the entire house and it's for small runs less than 8 ft. Great product and I would recommend it if you know how to utilize it. ... show more

  • Very dispointed
the last Kenuos water heater I bought lasted 2 years and the tank started to leak; I bought this one because it was the upgraded improved model. This one leaked at the pressure/temperature relief valve even with proper thread seal and tightening the valve until it bottomed out on the water heater. It appears either the fitting to the tank or the relief valve are improperly machined. I requested a replacement as I need some sort of heater the run to the kitchen sink waists tons of water waiting for hot water. ... show more

  • Quick, easy replacement, saving a lot of electricity
This is really a nice deal. It's nice to be able to have quick hot water, but not have to heat up this gives you what you need. Usually real quick and saves you a lot of energy so far everything is good. It was an easy replacement, it was, it's small so. Definitely saved a lot of space. The flow rate on it is fine. It's just as it was before, there's no problems with that, and it fits just about anywhere, which is a nice thing with the space-saving. And the quickness of the water heating, this is a really good deal TO it's a great design, easy to install, and it's functionally. Perfect so far I don't see any issues so. Definitely. A good deal highly recommended. If nothing else put it in and then take out your other one. Try it first works for me. Love it. ... show more
