Rated 4.6 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Rheem 9.5 gpm Had a 40 gallon water heater on the second floor of my two storie home. Installed this on the first floor outside, so there was a lot of work just to run the gas, power, and water. The unit howerver was very easy to install. I have read other post on here about people not being able to buy the "Rheem tankless water heater valve kit" and having to order it. Homedepot does carry in the store the "Watts tankless water heater valve kit" watts is a very old and very well known plumping part company this kit is a must have to install this unit. Also the beat way to mount this is with Uni strut. And I have to give a shout out to Dasiy who works the plumbing dept. at Homedepot Burbank this lady knows her stuff and was a huge help.

Rated 5.0 out of 5.0 by Outstanding Unit! UPS delievered my new tankless water heater at 2:37 this afternoon and we had it installed and running perfectly by 6:25. And that included removal of my old Bosch unit and a trip to my local hardware store to pick up a few fittings. The unit delivers hot water in 8 seconds, and I have run it continuously now for 15 minutes in 2 showers and the kitchen sink with no drop in temperature or pressure. Being thoroughly familiar with tankless heaters - 6 years - I can overwhemingly endorse this product! April 16, 2013
Rated 5.0 out of 5.0 by SUPERB TANKLESS WATER HEATER I have had the 199,900 BTU Tankless Water Heater for almost a year now and it was a great choice. It is located outside, so I did not have to worry about exhaust. I have had 3 showers going in the household with no problems. I would recommend this unit to anyone!! February 27, 2013
Rated 5.0 out of 5.0 by Better than I expected I have been completely satisfied with this water heater. My previous experience with tankless left me wanting more, but this one doesn't. Hot water is delivered fast and consistent and I no longer have to worry about my children using all of my hot water. March 12, 2013
Rated 5.0 out of 5.0 by High Quality Workmanship and Operation Purchased Rheem ECO200XN3 efficient tankless hot water heater. Unit has extremely high quality workmanship. Quick shipping from Home Depot kept my construction schedule on time. Installation was relativity easy but requires strict adherence to local codes. The remote controller feature is a nice touch. Start up was easy. This unit will pay for itself in less than two years. June 5, 2014
