Rated 2.8 out of 5 by 4 reviewers.
Rated 1.0 out of 5.0 by Failure in first 24 hrs of operation The water stopped working after the first 24 hrs of use. After troubleshooting I determined that the gas solenoid valve was not getting voltage. I removed the circuit board for inspection and found the backside of the circuit board charred and burned in the area of the connection to the gas solenoid. I have spent half of my day on the phone with the tech support to get this resolved. We'll how that goes... November 29, 2015
Rated 1.0 out of 5.0 by Water Heater will Lock You Out Dont' buy a Rheem water heater. It is in a state of factory lockout AND the factory supplied, factory certified factory repairman cannot unlock it. WE had to show him out to enter the special code to get out of lockout, thanks google. But no avail. Goes back into lockout. No dagnosis in lockout mode. No diagnosis, no repair! Policy is policy for Rheem. Finally our store manager got us a new unit. May 15, 2015
Rated 5.0 out of 5.0 by Outstanding hot water tank Great experience from ordering on-line to driveway delivery. Tank was packed with great care (on a double pallet) Hook-up was easy but running the intake and exhaust lines for a new install can be a bit tricky. Great instructions that are easy to follow and understand. Heat's water quickly and the fan motor is fairly quiet (I have mine in a utility closet within living space.) I would buy this unit again as it just oozes with quality.. We have yet to stress it out running a dishwasher, washing machine, and a hot shower running at the same time. We also have this unit set to it's lowest temp setting as it can really heat up some seriously hot water on higher settings. Expensive but worth it in the end....we shall see. October 14, 2014
Rated 4.0 out of 5.0 by Hot Tamales Purchased this unit in part because most (all?) other high efficiency water heaters were too tall for my 1918 home's basement height. First delivery there was damage that I noticed after unpackaging it for the install. Took it back myself, which is a pain. Installer recommended taking the next one out of the package while delivery guy was still there- duh. Next one was mint, and installed nicely. Note, that since it is a condensing heater, you will need a sump pump (not expensive) for the drainage. I tapped into the sump on my furnace, which was convenient. It is a 38gal, and I was replacing a 50gal. No issues with capacity so far. So far, the water is hot, noise level not too bad. Been installed for 1mo, no issues. Hopefully other people will write reviews on this, as the lack of reviews made it a bit difficult to purchase. July 3, 2014
