Be careful of this water heater!
This was installed by a great company under contract by Home Depot. The unit installed worked great, lots of hot water and heated up quickly. I wasn't aware of some of the features, now I wish I was because I probably wouldn't have purchased it. Apparently this model and maybe other models have sensors. I always think of this things like automobile "thing" that they add on, sensors, power this, power that...just things to go wrong. So apparently the sensor in question is questionable on reliability. After 6 months it started shutting down, seriously I thought this is what we are trying to avoid, the problem of a malfunctioning heater. So it started to flash 7 times then pause, then 7 times, then pause etc. Apparently the problem is "Flammable vapor sensor lockout" due to something that will catch fire. Nothing has changed in the room, I've left the door open to ensure air movement but still going into this state. Now the kick in the , rear pants, apparently Rheem has decided to not cover this part under warranty! The sensor has a history of failing so what do they do, not warranty and the owner is on the tab. All we wanted was a hot water heater, it didn't need sensors (like power windows on a car, power locks etc.) we just wanted a water heater that we could count on. Now Rheem wants customers to contact them first before any warranty work is performed so they can say "nay or yah" not what I call good customer service. The manual doesn't give instructions on how to reset the unit!!! What the "devils home"? I haven't contacted them yet as considering all our options at this point. But having to reset the water heater 4 or more times a day to keep hot water is extremely frustrating!

    Works okay, but has a faulty sensor
    I’ve had this water heater for over a month and it works well for heating the water...but it occassionally has a ‘faulty’ sensor where the control panel flashes blue. Per Rheem’s manual it means there’s no hot water flowing and somethings wrong. Doesn’t make sense why Rheem would make a product that has constant issues with its electrical work. Be smart and just but a water heater from a contractor.

      Efficient Problem Free
      This heater has been PROBLEM FREE for some time now, after the rebate from the gas company it made the price close to the cheaper models. be smart and factor that into your decision to purchase it. My older unit had a blanket on it to reduce heat loss this model it is not needed. I cant feel any heat loss by touching the sides of it when in use. I also recommend the use of a water recirculation kit because it reduces wasting water at the shower waiting for the hot water to start. It also warms the floor were the pipes run. depends where your pipes are roughed. The recirculation can be turned off in the summer and is controlled by a timer to match your hot water needs. This heater is electronically monitored and controlled flashing led indicates its status, the burners are a lot louder than older model but it heats faster and has lowered my gas bill.

        We had to replace our old water heater as it was growling at us everytime we turned the shower on. The hot water was not very "hot!" This water heater is quiet and the hot water is TOO hot so we had to adjust it. Our shower doesn't growl at us anymore and we have plenty of hot water now. I would recommend this product!

        Perfect size and fits into corner with ease. Best warranty I could find. I’m holding off on the phone interface until Rheem perfects their program. The water is hot and supplies my needs.
