A select group of Rheem electric water heaters (not included with this purchase) available now at The Home Depot include first-of-its-kind WiFi functionality. Using Rheem’s exclusive EcoNet technology, homeowners can take total control of their water heater from anywhere with Internet access. With the free Rheem EcoNet App, homeowners can set the temperature of their water heater, and access a number of features such as Leak Detection, Service Diagnostics, System Status and more. You can also remotely set the water heater to Vacation Mode so that it’s not heating and reheating water when no one is home to use it saving energy and money. The Rheem App is available as of June 2014 for Apple iPhone, iPad and iPod users. This will be available for Android users as well. Plus, this new technology speeds up any service calls by arming homeowners with an error code that they can give their contractor ahead of time. This time-saving feature helps the technician know the problem up-front so that he can bring the right tools and equipment to their home.

  • Rheem WiFi module mounts on the side of the water heater and it connects easily through a communication cable
  • With this functionality, the water heater communicates through your in-home WiFi network
  • Module can transmit important water leak-detection and other diagnostic alerts to homeowners
  • Certain Rheem electric water heaters also have an audible alarm, which creates a sound from the water heater if a leak is detected
  • The Rheem EcoNet WiFi module REWRA631EWH works with the following Rheem Performance Platinum Electric water heater models: XE50T12EC55U0, XE50M12EC55U0, XE40M12EC55U0, XE80T12EC55U0, and the Rheem EcoSense Hybrid Electric Heat Pump Water Heater model HB50ES
  • This item is compatible with the Wink home automation system and can connect to several other items to control and customize your home with automated rules, shortcuts, & more, all with no monthly fees

Rated 3.3 out of 5 by 17 reviewers.
Rated 5.0 out of 5.0 by Great option to have. I considered this item during the water heater purchase but decided to wait. Glad I did!! It went on sale during Black Friday for half off. Very easy to install and control. I can adjust the Temp, on/off (disable mode), vacation mode and energy efficient mode off during daytime on only early morning and evening. Can't wait until I see the actual savings on my elec. bill. December 6, 2014
Rated 1.0 out of 5.0 by Nice Idea but has a mind of it's own. Very buggy .The unit shows connected but the app randomly drops it offline. The only way to get it back is to unplug it remove it from the app and go through the installation process all over. I'm an IT guy so its not like I don't understand networking. When it does stay connected for any period of time the Wink App rolls back scheduled changes 30 minutes after a scheduled change. Not good when the wife goes to take a shower and the water is at 110 degrees. This thing is pretty much in Alpha testing. Charging people to do this level of testing is just wrong. They should pay us to try it until they get the bugs worked out. February 25, 2015
Rated 1.0 out of 5.0 by Disappointed The WiFi module works, but if your home Internet service goes down, even for a few seconds, the module will not be able to re-establish a connection to the EcoNet service once your Internet service is restored, e.g. the EcoNet app on your iPhone will just say, "sorry, connection lost" when you try to check the status of your tank. At that point you'll need to unplug and reconnect the module when you return home for it to start working again. Great concept, but bad design. Hopefully Rheem will come out with a new version.

Rated 3.0 out of 5.0 by Works as designed - Don't buy it I purchased this product with the mistaken impression that I might get additonal capabilitiies for my water heater via my smartphone or other device. What it actually does is basically mimic the controls and information that is displayed on your water heater. It's not really even easier to use than the panel on the water heater. I was hoping for some usage information, actual water temperature (not just the current temperature setting) and maybe some graphs or charts. I am disappointed. I can see how this could be beneficial if your water heater was located someplace in your house where you couldn't readily get to it, maybe the attic or crawl space or something, or if you managed an apartment complex with dozens of water heaters that you wanted to control remotely. Not really very helpful for the typical user though. April 7, 2015
Rated 1.0 out of 5.0 by Useless product The installation was simple. But could not get the app to work on my cell phone so the product is useless. There is no help or support on the Rheem website. The packaging was thrown out by the time I installed it so it could not be returned. I disconnected it so it would not add to my electricity bill. July 21, 2015
Rated 5.0 out of 5.0 by Excellent product I had a plumbing company install a new Rheem HWT. I bought the wireless controll seperately and install myself. Actuall installation, taking out of the box, reading the instruction and installing the unit on the HWT took less then 5 minutes. Downloaded the Rheem Econet app, as instructed, from the Apple store, went thru the set up and less than 5 minutes it was working fine, no problems, no internet connection issues, everything perfect in minutes. Time will tell how the unit works, but installation and wifi setup was a breeze October 9, 2014
Rated 1.0 out of 5.0 by Overpriced even if it worked. And it doesn't. So, the Rheem app for Android states that it works with OS version 4.1 and above. Development has obviously been slow, because my new Galaxy runs v 4.4. Since the network the module creates doesn't connect to the wider internet, the phone's built in diagnostics quickly terminate the link, not allowing enough time to let the app configure properly. I happened to have a decommissioned Galaxy S2 running 4.1 lying around. I tested it out with the app and connection was no problem. Well less of a problem, but it worked. So, now I have a functional connection via the EcoNet app. Next step was to control it from the Wink app. After all, right on the packaging for this module it says "WINK APP READY: NO WINK HUB REQUIRED". Guesses as to what happened next? That's right, in the Wink app, no Rheem products listed. None. Would an in app product search help? Nope. But wait, there's hope. There's a function in Wink called "SCAN BARCODE". So I scan the barcode on the back of the Home Comfort WiFi Module, the barcode that sits right on the other side of the cardboard from the round WINK APP READY emblem. And here's the result -- "DEVICE NOT SUPPORTED: Oops! Looks like Wink doesn't support that device. Try searching for your device manually instead of scanning it." So, yeah, I broke a two year boycott of HD for this...and I'm again reminded of why I now spend my money at the blue store. This 'Wink app ready' joke is going back. Someday maybe HD will start taking their technical offerings seriously. August 29, 2014
Rated 5.0 out of 5.0 by Does even more... I have the Econet HVAC system as well as the water heater. The Econet wifi module allows me to control both through one app. Since I travel, it makes it nice because I can set both systems back when gone and bring them back up to normal before I return. Haven't had any faults but it is supposed to let me know if something goes wrong with either the water heater or HVAC. March 15, 2015
