Customer Questions & Answers

Do you have to purchase the Wifi attachment in order for the water heater to operate and adjust the control setttingsor can one still do this manually

Wanting for the 12 year warranty and efficiency, not to have to adjust through iffy Wifi connection at times.
Asked by: RedRyder
You don't need to purchase the WiFi attachment to operate this water heater or to adjust the operation (on or off) or the water temperature. I don't have the WiFi attachment, and my Rheem Platinum Performance 38 gallon water heater works just fine to automatically heat water for my home.

This heater has connections on top for hot and cold water hoses. Do I need dielectric connections?

This heater has connections on top for hot and cold water hoses. Do I need dielectric connections?
Asked by: Jack
Yes. The connections that come with the water heater are not dielectrically isolated. The installer will need to purchase and install dielectric connections to isolate the heater and address the potential for dielectric corrosion.

Can this water heater be vented horizontally through an outside wall?

The water heater that I'm replacing is a power vented bradford white that is vented out the back of the house with ofc piping. Will this unit be as to be vented the same way? Are power vented heater usually more efficient? I hope I'm not stepping backwards in efficiency.
Asked by: dave
Yes, as long as it meets code in your area.

Performance Platinum 38-Gal. Damper Tank Natural Gas Water Heater—High Eff, Mobile Alert Compatible and 12-Yr Wty is rated 4.4 out of 5 by 430.
Rated 2 out of 5 by from Controller failed after 7 months I bought it for a new house seven months ago, and it was fine until this morning. At noon, no more hot water. The error code indicated a faulty controller. On the web-site for this model, it says "Electronic gas control for improved monitoring and service" What a joke. I have multiple rental units with non-electronic controls on their water heaters, never a problem with them for many years. This new and improved one failes after seven months. Probably some EPA requirement killing the old reliable controllers. Thank you for the cold showers tomorrow.

So far the unit is working alright but I am extremely disappointed in Rheem. I bought the unit from home depot brought it home and had a licensed plumber install the Rheem unit. He could not get it to turn on and after checking all of the electrical outlets determined that the unit itself was not working. We called the manufacturer number listed on the front of the heater and they told us that they would have a rep call me "within a day or so." The agent at Rheem said "Oh yes we''ve had a lot of calls on this model. The electrical wires need to be replaced." Long story but I had to wait 8 days to get the part shipped to me from Rheem and have someone come and install it. That is 2 days off work, 8 days without this brand new unit working like it was supposed to., Very disappointed.

It replaced a 22 year old water heater that was still fully functional. I replaced it due to its age. This water heater has only been in use less than one month so a true evaluation of its quality and efficiency cannot be given at this time. I hope this one serves me as well as the previous one.

The boxing of the heater was substantial with no damages. The power chord for the electronic ignition was generously long for easy connection to an outlet. The replacement of the existing heater was even easier with the use of push on fittings for the copper pipe re-connection.

Rated 1 out of 5 by from Poor Design Feature Spent more on this unit than ever before expecting it to be the best. Immediately had the air sensor in front go bad. They sent a new one in a week. This one has been faulty too, since day 1! 3 or 4 times each day or night I have to unplug the machine and reset the air sensor. Will probably wear out the reset knob next.

Rated 2 out of 5 by from Disappointed After 20 days my new hot water heater stopped working because of a problem with the vapor sensor. The repair technician could not tell if the sensor was faulty or if it had been improperly assembled. He said one of the electrical wires appeared loose. I do not have much confidence in the reliability of this product.
Date published: 2017-02-14
Rated 2 out of 5 by from Needs spare Vapor Sensor All hot water heaters with a vapor sensor should come with an extra vapor sensor. We got our carpets cleaned, and the vapor from the carpet cleaning chemical locked up the vapor sensor. Warranty sent a replacement, but it was 4 days with no hot water. Now I keep a spare on hand.
Date published: 2017-02-06
Rated 5 out of 5 by from Works great Had it set at about 120 the first month. A few times it didn't turn on when temp dropped & took a shower with only hot water on.Turned temp up a bit & has been fine ever since. Otherwise, works great, no problems. Last Rheem lasted 28 years w/ soft water. Still a good product.
