This will only heat water for a sink or shower with water starting at about 55 to 60 degrees
Installed this heater for a remote bath. The house is in Florida and we are on a well. Water is stored in a tank about 200 gal. to off gas the sulfer, therefore the water is at near ambient temp. This heats the water plenty hot for a shower or to wash up at a sink. Not sure about how long it will work. Right now it works great!

Works Great - Excellent Quality
I had a forty gallon water heater go bad at my business. We only have two sinks used for washing hands only, so a big heater was really a huge waste of energy. I had first ordered a Bosch US7-2R, 7.2KW. It quit after only a few days. This Rheem 6KW seems to work just a tad bit slower in warming the water, but I like it much better. I love the display that tells you the temperature of the water leaving the heater and the fact it has an on /off switch. The quality of the cabinet is also much nicer and more ascetically pleasing. The Rheem also came with an electrical pigtail, the Bosch did not. This unit also seems to have much heavier water connection fittings than the Bosch. Overall this is a nice unit for one or two sinks in close proximity.

Worked without issue.
Good for single sink use. Not ideal for shower due to temp based on flow. Valves with no volume control would not be able to regulate variable temp coming from this water heater.

Works but @ very low flow rate.
This is my 2nd time purchasing one of these. I originally installed one of these heaters for a small hand wash sink. It did the job, but was lack luster in performance. I tried one of these a 2nd time, for a different customer for a single sink. The flow rate has to be turned down so low the sink isn't usable. If you turn the flow rate up the heater isn't able to heat the water fast enough so you're left with luke warm just over room temperature water. I ended up removing the unit and going with a larger one. Even the first customer I mentioned I later found out they were unhappy with the heater, but they are keeping it because it is just a shop sink. So 2 for 2 with very poor performance, one of these I had to uninstall and eat the loss. I'll probably never buy of recommend again. They just aren't powerful enough to get enough jot water at a high enough flow rate to make a sink usable. If you are ok with cutting the flow rate down to a trickle then this heater will heat the water burning hot..... but as soon as you increase the flow rate no more hot water.

Love this little water hearter.
My favorite result on this unit is how little room it takes up and just hangs on the wall. Our old standard tank water heater gave out and took up so much space in the laundry room. Easy installation took us less then 30 minutes (we did have all the correct new fittings needed). Takes a little time for the hot water to reach temp and get to the kitchen sink, it's not an instant hot one but does get very hot. The slower you let the faucet run the faster it gets up the temp. All in all it was worth every penny.

Lasted less than 2 years
This water heater would never keep up with the demand for one sink. It stopped working at all in less than two years. I expected better from Rheem. Might as well go cheap.
