What does it mean when it flashes 11 on the thermostat

Asked by chamblee August 19, 2018
5
Answers

Ignition has Failed 10 (Ten) Times. For the Rheem Model # ECOH200DVRHLN Performance Platinum 11 GPM Natural Gas unit; Make sure you have at least a 3/4" natural gas line installed to feed this beast.& ensure the natural gas pressure is between 5.0" W.C and 13.0" W.C (1.25 to 3.24 kPa). Your local natural gas company will check it for you for free, mine did. Press the Power button to clear the Error Code. If Error happens again: 1. Monitor the gas pressure to the water heater while in operation. Ensure pressure is between 5.0" W.C and 13.0" W.C (1.25 to 3.24 kPa). 2. Check gas valve wire. Ensure connection is secure. 3. Check flame detection sensor. Ensure connections are secure. Normal operating settings are more than 2.5DC before ignition, less than 2.5DC after ignition. 4. Check igniter transformer for proper connection. 5. Clean the spark igniter with steel wool to remove oxides. Ensure proper separation (3-4 mm). 6. Replace the spark igniter if damaged. 7. Assure that the flame is stable when lit. 8. If the problem persists, replace the main control.

Can this model be installed without the crossover valve and just leave the recirculation disabled?

Asked by DR October 28, 2018

Answers

While I am not a plumber, I am reasonably confident that your idea will omit the potential problems. I have not installed my crossover valve yet for the same reason. You should consider calling Rheems level two support team to confirm.

Is loud humming noise normal? I have a Rinnai in Asia which is very quiet.

Asked by Jerry December 17, 2019
4
Answers

You should not have a loud humming noise you might have to adjust the hex screw on the unit that regulates the incoming gas pressure to your incoming gas pressure. You need to make sure you have 3/4 inch line to the unit ( no flexible 1/2 inch line) and ensure your air input and air exhaust is separated appropriately and without restrictions.

No, the recirculating pump turns on in a schedule, as well as when you first install it, it learns your water routine and works with that. you can also install a kit that has either a button or wifi controls to turn on the recirc pump on demand.

Asked by Sloan March 4, 2019

Answers

Don't do it. Tankless water heaters are notorious for breaking down, leaking, and finally failing completely. I have known many people who have bought Rheem and other brands and experienced these problems. In the end, replacement and repair costs far exceed any energy savings. The technology for these things is still in its infancy, just like heat pumps in the 1970's.

Can this unit be installed in the attic?

Asked by ZachS August 14, 2018
4
Answers

Good question. My regular tanks are in the attic now and was thinking it would be safer not to have 2 tanks full of water in the attic and therefore much safer to have a tankless.

80 Gallon Electric AO Smith water heater bites the dust after 8 short years. Was pondering between Rinnai & Rheem. Both really good quality, but I went with the Rheem due to flexibility. We just finished install today. Our install was a bit different as the local gas company had to run gas to our house. With that we had to run the gas line in the house and connect to meter, as well as intake and exhaust to a 3" concentric vent. Overall the install went very smooth. I really like how you have options on the venting 2'' vs 3'' etc. I'm going to play around with it this weekend to figure out what sink is the furthest to hook up re-circulation. Since that isn't hooked up yet, it is taking a bit longer to get hot water to the faucet. It didn't take long to set up on initial start up. The user interface is pretty simple to follow. I can't believe how quite this thing is. If the burner indicator light didn't come on, you'd never know it was running. I give this thing an A+. No more worrying about running out of hot water. Will update once re-circulation is set up.

I bought this online (this model wasn't in the store) when my water heater decided to spring a leak in the middle of the stay at home order. Shipping was good, professional delivery, delivered it right to my garage. Unfortunately due to the reduced hours of the store during the stay at home order, it took several trips to the store to get all the additional parts to get it installed. It took the whole weekend to get it up and running. The cost of this unit is one thing, Keep in mind that after this purchase, if you plan on installing it yourself, like I did, it will cost about an additional $800+ or so, in parts, depending on what you need to install it. Vent pipes, additional black gas pipe, a flexible gas hose, for the final connection to the unit. I also purchased the Concentric Vent Termination Kit, you can cut it down to the size you need, make sure to leave the proper lengths to make the connections properly seal. Also, this unit does come with the service valve kit already, so you don't have to purchase those separately. Just make sure that you do your research before hand, make sure you have the right gas lines running to the unit, and that you have good access to run your vent lines, have a place to actually hang the unit. etc. There are good resources on youtube for assistance in installing.

Worth the upgrade
I've had this installed for 6 months now and I'm glad I did. It took about a day to install. Saves space. Operates quietly and definitely has saved me from having to get oil deliveries. Easy to maintain. Only a couple filters and an annual check from a professional. It also lowered my total water usage for house. For anyone who has an older system like I did will benefit from doing this upgrade.

My mother said, if you don't have nothing nice to say, don say nothing....sorry Mom! Got installed (by professionals) right after 5 PM PST and just didn't work, the unit will not fire up....could hear the ignition trying to go but that was it!...called their customer care and to my surprise, they don't have 24/7 support for this unit!!!! Cold water for three days!!!Thank you Rheem! Call on Monday and after 80 minutes of trying to troubleshoot the issue, the final verdict was that there was no gas going into the unit and that a supervisor was going to follow up...never got the call, however, called the plumber/installer to check on the gas and....yes, the unit was getting gas, in another words, I won the lottery of Rheem bad water heaters.... The only good news is that HD is taken the unit back and refunding my money. The real bad news besides cold showers, no dishwasher and laundry is that, I have to install another thankless water heater (replacement) with an installation cost of over $1,800 since is practically a new installation!!!! So, save your self cold showers, frustration and MONEY....buy from another manufacturer!!!!

I bought this unit because I had an existing tankless unit that had recently failed. I disliked the cold water sandwich, and I was hoping that the recirculating pump would eliminate it. It did not (yes, it was programmed and turned on). After almost 3 months of use, my biggest complaint is that the temperature control seems unable to maintain a temperature with changes in flow (i.e. don't try to take a shower with any other appliance on). I live in central Ohio, for those of you curious about ground water temperature.

It worked for only 2 weeks and stopped working after that. The technician said it was defective from the factory. Had to return, paid a lot of money to install it and extra to uninstall, not to mention they do not keep it in stock. A week w/o hot water. This tankless turned out to be a nightmare, and nobody seems to take responsibility including Rheem.
