I’ll preface this review by stating this heater is only being used for a single sink and a bidet in a warehouse.With that being said, I’m quite happy with my purchase. It was easy to install, the water can actually get very hot even if set only about 50-60% of the way and I haven’t had any leaking issues. I’m no plumber but I know to always use pluming tape when installing plumbing accessories.The item does require a decent amount of space. It is a two gal tank after all but other than that I have no issues; and it does fit under the bathroom sink pretty comfortably.The unit is used during the day time only and is shut off at the end of the work day. I’ve had it for a few weeks now and that seems to work really well.It also only takes about 10-15 mins to get to temp when set at 50%. It may heat quicker if set to max.

Easy install. Worked perfect. No need to set on max setting. Extremely hot water at maybe 3/4 setting. I use this at my furthest fixture....Kitchen sink from tankless water heater. Don't have a dishwasher.....no need, I have a Tiny House. Yet, if I desire more hot water than this unit provides my tankless kicks in. New in use, I'll convey in one year if its still doing well.Again, easy install and works great.

Worked great for about 5 weeks. We did have to purchase different hoses, since the ones provided did not fit our connections; which are standard. Now it barely warms water and only for about 30 seconds worth.I DO NOT recommend this mini water heater.

We had a problem in our new home, where the tankless water heater was quite a ways from the kitchen. It took 90 seconds or more to get hot water, which seems like a lifetime. We decided to get a hot water heater that we could put under the sink. Some models require 220 V which we didn’t want. This model only requires a normal 110. The purpose of this hot water heater will be to get instant hot water. We can then wash hands or rinse dishes, which only uses a small amount of hot water. If we are filling the entire sink, then the hot water in this tank would be exhausted and the water coming from our whole house tankless water heater will fill the rest of the sink.After installation, we are super happy. And we don’t see any decrease in water, pressure or water flow. The water is hot in about four seconds. This is a perfect solution to a problem that we had.A few comments on installation so you know you can do it. They do not include any white Teflon tape for sealing the joints. You need to purchase this from Amazon or your local hardware store. Instructions they provide are not really good. But there’s not that much to actually do so it’s OK. If you don’t know how to wrap Teflon tape, then I suggest going to YouTube and finding out how to do it. The installation is simple wrap tape on the top of the two water ports. install the safety valve on the cold water inlet pipe on the top of the tank. Put white tape on the top threads. Next under sink turn the hot water off and disconnect the faucet pipe that is going to the shut off valve. Connect the new pipe they gave you to the shut off valve and then to the cold port on the tank. Now comes the tricky part. The line coming from my faucet that should connect to the tank did not have the same size end and therefore I needed to go to the hardware store to pick up a connector. The guy there helped me get the right one. I applied white tape to the connector and then connected everything. At this point, I tested and found a leak. I need to apply more white tape in order to get the leak to stop.In summary, great product, solved my problem, and I’m happy

It gives you about 2 1/2 gallons before starting to get cold. Fortunately for under my kitchen sink when connected to the hot water line it allows just enough hot water to compensate for the cold that typically comes out before hot water from the household hot water heater gets to the sink. For me it works for what I need it and the price was right and I already had a 110v outlet under the sink. I would only use this for the same purpose. I would not purchase it for any other purpose.

Works as advertised but has low flow on full hot. Fits in small space.

Water heater went in easy. It’s really hot if you want it I like the flex lines on it. This is the first one it went under a counter in our food pantry. I have bought two of them. I’m fixing to put the other one in the bathroom remodeling, everything was good.

Una vez que surte el agua que tiene en el tanque (esta si está caliente) el resto sale frÃa. Lo instale en cocina. No dura el agua caliente ni dos minutos.
