Questions & Answers

Q:Can this be powered by UPS for several hours or few days? If so what size/rating of UPS would be required? Does the unit require constant power or just to ignite? Someone said inexpensive auto power inverter but can't run car for hours to power.

Answer This Question

A:  Hi Aced, we wouldn't recommend the unit to be wired to a UPS as that may interrupt the unit's heating operation or can affect it negatively. The unit does require constant power to detect when heating is necessary.

          Worth spending the extra $$
          Works great. Has a guide to tell you the flashing light cycles. Easy startup. Do your research. It had the longer warranty. This one fit perfectly and worth the $$.

          Piece of crap!!
          I purchased this product in the end of April and on May 1st it’s not working. Called the customer support and had to wait over an hr to be answered. They mentioned the ignition device is faulty and needs to be replaced!! And they would ship it in 2-3days (so no hot water) and there is no overnight option! I read this in the reviews before I purchased and thought it might a one time thing. But it happened to me. I don’t recommend this product bcoz a brand new heater should not have a faulty part...that’s crazy!!

            Nothing but trouble
            Bought this because it was energy efficient and had a rebate option from Questar gas. We have had many repairs, all relating to the electronics. We have pretty much replaced all the main parts now, and as we fix one thing the next part fails. Warning, if you buy this you cannot return it to Home Depot, and you have to contact the manufacturer for all repairs. Initially it would not fire up. After working with Rheem and doing a lot of diagnostic at home they send a new burner module with a new thermocouple. Still would not stay lit. Cleaned the thermocouple and it worked for a couple months. Then one day it quit again. After rebooting 3 times it stayed on--for a couple weeks. Called the plumber and he advised we replace the gas control module. Called Rheem and they shipped it. Plumber installed it, but now there is a new error that blames the vapor sensor. No one in Salt Lake or the Wasatch front carries the part so we are currently waiting for Rheem to overnight it. Their tech support has been professional, and I believe that the cheaper model without all the electronics would work fine. But I can't recommend this model.

              Not a drop-in replacement for previous models of Rheem water heaters with same specs. Height/Dimension difference required flue adjustment. Not a big deal, so gave an “average” review. Too many 5 star reviews out there. The purchase, ease of installation, and price did not blow me away, so not 4 or 5 stars. I would be open to upgrading my review if the cost savings (efficiency) improved significantly. I would have preferred tankless, but the cost difference is massive, with relatively little return on investment in the near term (5-10 years). If I was planning to live in this home for longer, two tankless (on demand) heaters in series would have been my preference. Probably would have bought Rheem tankless too. Be very careful transporting the units as they are glass lined and have sensitive (glass) earthquake sensors that can get damaged. When possible, transport standing up. The dad thing is there is no way of telling how careful they have bee delivered to and stocked at home stores, so prepare to get a dud.
              Response from RheemJan 31, 2021

              Thank you for being loyal Rheem customer. We would love to hear your cost savings story after having more time to enjoy your heater. If you ever have any questions or concerns please call Technical Support at 866-279-4566 between the hours of 7 A.M. and 7 P.M. CST and one of our experienced analysts will be happy to assist you.

                Just installed this over the weekend and it was easy to install as far as connecting everything. The only hard part was getting it onto the platform. This sucker is heavy. Good thing the wife and I do deadlifts and squats LOL. We literally deadlifted (using our legs) and heaved it on over the pan and onto the platform. A lot of praying and wishing to the universe and we got it up. The connections were solid and the igniting of the pilot light was fast. Water is super hot and the unit is quiet. This water heater is definitely more sturdier than my old Whirlpool one. There was a little hiccup regarding which Econet worked with this model and I was a little bummed to find out that the current Econet that was meant for this particular model water heater was not compatible. Originally I had a review with 3 stars because of that issue, but within a day I was contacted by Jennifer from Rheem. Jennifer quickly got all my information to see what was the issue and to see if there was a remedy for it. Come to find out, there is a working Econet model that was in development. Within a couple of days I got my hands on the correct Econet model and installed it within 10 minutes. Very easy to install and pair up to my wifi. The correct part number is EEWRA631GWH. Thanks so much Rheem and also a big thank you to Jennifer at Rheem for staying on top of my issue!

                  Purchased from Home Depot and installed this water heater in Utah. Right off the bat, there was an issue with the pilot light not staying on. Rheem's customer service was fantastic, they sent us priority mailed a new pilot light assembly. My plumber installed it, but that did not fix the issue. Rheem then priority mailed us a new control unit that goes in the front. Again, my plumber installed it, and that didn't fix the issue. After over 10 days of being without of water, Rheem allowed my plumber and I to return the unit back to Home Depot for a new, replacement water heater. The new water heater had no issue and worked the bat (and saved my marriage). Rheem is having issues with this model (see the other complaints). Their customer service is very good, their reimbursement for my plumber was slow (~4 weeks), but they were fair and they did reimbursed me for all the additional plumber labor costs. I would stay away from this product until Rheem can figures out and can correct this issue. I'm not sure if the issue is because of the Ultra Low NOx and I live in Utah which is at 4,000 feet elevation or this is an internal quality control issue. If you do install this product, and it doesn't work right off the start, I would recommend to immediately return the unit to Home Depot for a new unit (50/50 the next one will work). In my case, Rheem's replacement parts (pilot assembly and control unit) did not resolve the issue.

                    Review of XG40T12DU38U1 with power damper. Before buying this heater I also reviewed tankless and hybrids. Based on cost, efficiency and design life I think this one offers the most value. Installation was straight forward. I first installed a dedicated receptacle as I don't want to give up any in the garage. I built a lower stand to accommodate the higher height of the flue damper and water connections (a stand is not required but I need one for my dryer vent). My water supply does not have a backflow preventer and no expansion tank is required. The tank diameter is about 19.75". If you plan on setting it in a drip pan, a 25" diameter will fit the tank and gas control shield. This model also has a sensor which will shut down the heater if it senses a flammable vapor. It is set very low in the tank and cannot be blocked or allowed to get wet. The damper on this model is normally closed. Upon calling for heat, it is opened electronically. All controls are 24 vac. In the event of a power outage, the system will automatically reset once power is restored. Annual fuel cost is estimated at $189 and 173 therms. Overall, it's an efficient, quiet, simple design with modern controls and it fired right up with no problem. Very pleased so far.
