does this qualifies for energy star rebate program?

WHAT HAPPEN IF THE POWER GOES OFF, DOES THE HOT WATER HEATER STILL WORK?

Asked by: MILO
No, this unit has to have 120 volt to power the transformer for the control unit and the power draft valve... This Power draft valve opens and closes the air vent going out the exhaust/ flue pipe to hold in more heat. This valve opens fully before there is even ignition of the tank flame. There is no manual lighting with a match for this unit, all electronic!

It took us about one hour and a half from start to finish. I have had it for almost two months now, and so far we are very pleased with the unit. I purchased this water heater because of the longer warranty and of course the Star Energy efficiency. This heater should save us a couple of hundred each year. It also has a nice feature if we decide to buy and install the remote temperature controller.

This water heater exceeded our expectations, we used it to replace a 21 old gas pilot water heater that worked VERY good and also exceeded its life expectancy and did not die until we turned it off. But what we like about this new Rheem is the AUTOMATIC way to turn itself without a pilot!!!

Rated 1 out of 5 by from Terrible product!! We purchased this with same day pick up only to have it fully installed and find out hours later that it would not turn on, like many other reviewers said. We called Rheem and told them about the faulty part. We also mentioned that we have an infant son and it's still winter in New England so there is a sense of urgency- THEY DID NOT CARE. We were going to have to wait four days. We then called Home Depot and like usual, their customer service was amazing and they let us return the product for a full refund. Rheem should take a lesson. Thank you Home Depot for being reasonable and to all those looking to buy this product... take a serious look at other brands and spare yourself the hassle.

Rated 5 out of 5 by from Great Water Heater! After researching available water heaters I decided on this one for the following reasons: 1) It feeds air from above floor level, which doesn't require frequent cleaning by either me or the plumber because of clogged floor-level vents; 2) it is approved by PG&E because of superior efficiency; 3) a PG&E refund allowed a more expensive model, which didn't cost more after figuring in the rebate. All of these points have worked out to be as hoped. This heater allows my husband to take longer showers (not really cost-effective {which I discourage} but it makes him happy, and our gas bills haven't reflected these L-O-N-G showers because of the efficiency of the unit. It's been a great purchase!

Rated 1 out of 5 by from Steer clear of this water heater Bought this water heater yesterday and it doesn't work. Called the 800 # and it was diagnosed as having a bad transformer. Unfortunately,Rheem doesn't have a new transformer in stock to send us, but may have some in stock in about 2 weeks. Our options are to find and buy a new transformer or to uninstall and return the unit. Rheem will reimburse us for FMV of the transformer, excluding shipping and handling. I've seen the parts online for between $25 and $85. Rheem sells the part (when it's available) for $28, so most likely, they won't reimburse any more than that. Seems ridiculous since we'd be happy to have them ship us the part, but they don't have it. So very disappointed. We don't recommend this product or Rheem.
