Easy enough installation and awesome water heater
The Rheem tankless water heater was fairly straight forward to install as a DIY'er. We're super happy with its performance and endless hot showers! I replaced a traditional 50-gal storage tank, and we couldn't be happier. I installed in over a month ago and it's worked perfectly from the moment it was turned it on. The only downside is the internal recirc pump is a bit noisy, which resonates through the house due to how the water heater is mounted to the studs. It's not too noisy, but I could've improved the situation by using vibration isolators. I might do that some other day.

    DIY installation
    After my 3rd Bradford White traditional gas water heater leaking almost immediately after the 6yr warranty expired I decided to go tankless. Installation was straight forward for a DIY person. So far so good

        Constant errors causing no hot water
        It's been 3 years owning this tankless and we have had nothing but headaches. It's a pain when you're in the shower and water does not heat. Constant errors occurs like 20 60 and we would have to go out to heater and cycle the power.

          A month ago, ever since I installed this product Started to have issues with no hot water whatsoever! I called Rheem and followed the instructions to drain out the water and restart the unit still not working (power green light keep flashing, with Error code 66, which is the mixing valve), several times attempted but still don’t work! Rheem technical staff told me will send me a new mixing valve to replace it but I never got it!!! I had to call again to hope they can expedite it! I will not recommend this product, the customer service is awful to deal with (always line busy, or when lucky they picked up put you on hold forever!). I’ll wait for couple more days, or I’ll need to tear the unit down and return to Home Depot!

            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.
