Rated 4.0 out of 5.0 by KJ Instant hot water
This p-o-u hot water heater was installed by a plumber, two weeks ago under our kitchen sink. Our whole house instant hot water heater was so far away we were wasting two gallons of cold water before the heated water reached the kitchen. Right now we are very happy.
We gave it 4 instead of 5 because our previous heater's heating element had burned out. Same model. In 5 years from now we may write a new review giving 5 stars.

This tiny water heater goes under the new bath vanity to boost the incoming hot water line so you always get warm water in 2 seconds without waiting for it to come from 70 feet away at the main tank.

The hot water heater is easy to connect using flexible supply hoses purchased seperately. Both heater and flexible connections are 1/2-inch (female) so close nipples are required to connect to the heater to flexible supply lines and then to the water system.
It would be helpful if the amp requirements of each size hot water heater were listed on the box to allow easier matching of the heater to the available (existing) electrical outlet. Wattage is listed so the amps can be determined by dividing wattage by voltage to obtain amps. Maximum amp rating should not exceed 80% of the breaker to be utilized, to reduce the possibility of nuisance breaker trips.

The first one I purchased starting leaking. We didn't notice it right away until the next day when we found the bottom vanity shelf and contents wet. I did notice while picking it up at the store that one side of the packing box was crushed so I asked the associate to open it and we checked it out but saw no obvious damage to the water heater itself. It was the only one in sight so we went ahead and took it. I unhooked it and took it back out, wiped up the mess and re-istalled it - this time set inside an oil drain pan. After turning the water supply back on I saw it immediately started to create a puddle of water in the drain pan. The leak was coming from somewhere inside the case running out the seams. I took it back out, drained it and returned it to the store trading it for another. The second one has been working without any issues so far.
*There has been no burping when the faucet is turned on as described by other reviews.
*After installing the 1/2" nipple into the cold water inlet and after hook up to water supply I saw that it was not sealed properly. After taking it back out to see why I saw that inserted into the cold water inlet is a long plastic tube. This tube is not shown in the parts diagram. I can only assume that it forces incoming cold water to the bottom of the tank so that the hotter water above it is used first. I pulled the tube out, put it into the 1/2 nipple and then installed them both as one. That sealed it up properly.
*After not being able to find a smaller drain pan to use under the water heater I just left the oil drain pan there. It is a perfect fit for the tank. I highly recommend using something.

I bought this water heater to replace a Bosch Aniston point-of-use water heater that failed for the second time. My hope is that the Rheem unit will outlast the Bosch. Time will tell. However, I can tell that the Rheem does not heat the water as evenly as the Bosch. The Rheem has the safety valve pointing to the rear rather than the side, making it slightly more difficult to install a drain line to the safety valve. Additionally, the hot water pops audibly and sputters a bit when it is turned on after sitting awhile, especially overnight. I view this as a minor annoyance and not a problem as such, but the Bosch units did not exhibit this behaviour.

Picked it up at the store, Store employees loaded it into my truck took it out of the box at work and it had dents on three out of the four sides. Very disappointed.

Replaced my old Rheem 2.5 gallon (used over 20 yrs) which was very reliable and worked well, with this new one. Installation was fine. But the hot water always spat out when turned on for the first time or after not used for 30 minutes or more. Consultations with Home Depot expert plumbers as well as Rheem were unsuccessful to find the cause. No leaks in line etc. The sinks in the rest of house did not do this. The old Rheem 2.5 gal water heater didnt do this.I unplugged the heater and it still did this when cool. Took it out of the line and no more sputtering. What a bummer. Dont recommend this heater. Returned it.
