Rated 4.5 out of 5 by 37 reviewers.
Rated 5.0 out of 5.0 by No complaints It was fairly easy to install and has worked perfectly. January 27, 2015
Rated 4.0 out of 5.0 by Rheem water heater In general this is a good product. It works reliably and quietly, and, as far as I can tell, efficiently. The only problem has been that it seems to run out of hot water sooner than I would expect for its capacity. December 20, 2014
Rated 5.0 out of 5.0 by Easy install and use I installed the 38 gallon Rheem natural gas ultra low NOx at my mountain vacation home which replaced the very old (perhaps 30+ years old). The only help I needed was to lift the water heater into position - it is somewhat heavy for me to do it my myself. Lighting and operating the water heater is a breeze with the built in piezo-electric spark generator. The results: lots of hot water! December 10, 2014
Rated 5.0 out of 5.0 by Performance Plus! Great unit, easy to use, .easy to install, easy to light and has a good manufacturing warranty. December 16, 2014
Rated 5.0 out of 5.0 by Excellent replacement for tankless After determining that the exhaust pipe configuration was not compatible with this unit it fired and has worked well during the past six months. An instruction to use only one 90-degree elbow in the exhaust setup would be helpful to another purchaser. December 10, 2014
