I have repeatedly had trouble maintaining a wifi connection with my Rheem heat pump water heater. Although it was and remain connected for the first couple of years in the last couple of years, I’ve been unable to reconnect. Disappointing. ### 1/5 — Terrible app *2026-07-31, version 6.17* Won't pull error, even though it shows it in app and on water heater. Tried to create an account, Error HTTP Request is throttled. Try again later............ ### 1/5 — Junk *2026-07-22, version 6.17* New app. New problems. Module connection problems. Fed up with it. ### 1/5 — Does Not Save Programmed Time and Temps *2026-07-22, version 6.17* I just installed this yesterday because my HVAC contractor installed a Rheem RETST800SYS to go with my Rheem furnace and AC. I programmed a schedule for one day, copied it to the other days and it does not save. I did it 2 other times and it did not save. I also adjusted the temp from the app on my iPhone, and it did not update. I had to walk over to the thermostat and do it. The purpose of this is the have it all work from my phone. I’m using the 2.4 Wi-Fi too. Getting ready to contact Rheem for support. ### 1/5 — It just gets worse… *2026-07-22, version 6.17* Was forced to update my old EcoNet by Rheem app to this new EcoNet app and I’m not sure what changed. Both apps are literally slow and janky. It takes forever to load, the UI is laggy, and the new app literally crashed on me at setup. Just creating a new account was terrible. I’ve already had to re-download the new app because it wouldn’t go past the sign-in screen and was stuck in a loop as if it was loading…it was definitely not loading. Now I can’t even get past the Add Your First Product setup and it’s doing the same thing with the loading symbol as if something is happening. The combination of this garbage app and the hardware limitation of the thermostat not connecting to my WiFi is driving me nuts. ### 1/5 — New App sloow *2026-07-22, version 6.17* Slower than molasses in the dead of winter ### 1/5 — App is junk and does not work *2026-07-22, version 6.17* App is junk and does not work, after regular business hours. Every time I attempt to change the temperature of my water heater it conveniently decides that it wants to revert to a lower temperature I am alerted that I need to contact customer support, however customer support is not open. It miraculously fixes itself in the morning, when customer support is open. This is junk stop tinkering with it and keep it simple ### 3/5 — Luke warm water *2026-07-21, version 6.17* Sometimes WiFi disconnects and water not heat up. Need to go through the WiFi setup to get it back to work. Disappointed! ### 1/5 — It’s doesn’t work *2026-07-17, version 6.17* The geofence never knows when I’m home or away…. ### 1/5 — I give up *2026-07-15, version 6.17* Trystero777: The issue with home /away has been an issue for years. If look at reviews you will see the same complaints back as far as 2003 with no update to fix it. So to avoid the away switching to home via app go to water heater and put in vacation mode directly on the water heater. Only problem is cannot get out of vacation mode through app and must go back to water heater. But at least stays in away mode. And you also learned that schedule not reliable. So when all said and done don’t use app. ### 1/5 — 2.4 …why not current technology *2026-07-10, version 6.17* I spent the better part of 1 hour configuring g, reconfiguring , restarts to all my devices , router and mesh network only to find it’s incompatible with current router devices. ### 1/5 — Worthless *2026-07-10, version 6.17* Since the day we installed our Rheem hot water heater this EcoNet has been worthless. It does not stay in the selected mode. If you put it in AWAY mode it switches itself back to HOME. I tried to thwart this with the SCHEDULE but it broke bumps out of that mode too. Save your money and get a regular hot water heater. ### 1/5 — Software *2026-07-03, version 6.17* The app is very glitchy. Crashes, functions are not very well thought out. You can do better. ### 1/5 — Really useless *2026-07-02, version 6.17* Every time I try to use this app, I have to reconnect my water heater. What is the point of a smart heater if I can’t control it when I’m not at home because the app forgot it? Controls are confusing too - I can’t tell if vacation mode is on or off, except by changing a setting and having the app tell me “vacation mode is on.” Just really useless. ### 1/5 — Stupid water heater. Never connected *2026-06-30, version 6.17* I have a mesh wifi, the stupid water heater never handshake with my iphone. The app keep on spinning and never connects. Let the 'dump' water heater just be a water heater. I fired the smart features. ### 1/5 — Compatibility issues *2026-06-30, version 6.16.1* Doesn’t seem to work with newer wpa settings ### 1/5 — Near useless *2026-06-20, version 6.16.1* About half the time the app shows disconnected. Occasionally, I can get it to reconnect, but then it disconnects again. It is not a Wi-Fi problem as thermostat and lights all work normally. ## Most critical reviews (10 lowest-rated) ### 1/5 — New app, no good *2026-08-15, version 6.17* I had the old app connected and working for years, but the new app that was forced on us will not link up to the water heater. Lost all WiFi abilities of this expensive water heater that had been working fine for years. ### 1/5 — New app not good at all *2026-08-14, version 6.17* Old app worked great. New app useless and won’t connect to WiFi making $3k water heater useless. Thanks rheem for forcing to use new app that doesn’t work. ### 1/5 — App saying it has lost connection with server. *2026-08-12, version 6.17* It’s been 17 hours since the app has not come back up to service. The message I got it said the app had lost communication with server. ### 1/5 — Once AGAIN the App does not work. *2026-08-11, version 6.17* As a network engineer I can tell you that this thing is connected and passing data back-and-for. The problem is on Rheem’s end as usual whenever they change something they break the App. And the customer service guy I talked to said that they need to create a fix for it and to wait 1 to 2 weeks. Are you serious? ### 1/5 — Owner *2026-08-11, version 6.17* Loses connection to WiFi when it is right across the hall from the modem. Also wish it would tell me when the compressor is running or when the heat is running. I hate this thing. ### 1/5 — Unreliable program heating schedule program *2026-08-11, version 6.17* The program water heater heating schedule changes on its own. And this has happened multiple times. There was no response when I emailed the company about this issue. This is disappointing. This is supposed to be the top of the line Pro Tera, hybrid water heater. ### 1/5 — App doesn't work *2026-08-09, version 6.17* The app seldom works as designed. I would not recommend it to anyone. ### 1/5 — Poor connection *2026-08-07, version 6.17* Program just stops working and won’t let me upgrade ### 1/5 — Update not being recognized *2026-08-04, version 6.17* I have updated the app several times and keeps telling me to update and when I click the app says “open”. Now it doesn’t load ### 1/5 — Digital thermostat gone *2026-08-03, version 6.17* Please fix it ## Most praised reviews (10 highest-rated) ### 5/5 — Good update *2026-08-09, version 6.17* The old app needed to be restarted every time it was used. This one is consistent ### 5/5 — Hot water *2026-08-01, version 6.17* Works great to monitor the heat on the hot water tank!!😎 ### 5/5 — Top tier *2026-07-28, version 6.17* This app is top notch for controlling hot water heater. From setting temperatures to resetting errors it does it all! ### 5/5 — MUST FOR SENIORS *2026-06-20, version 6.16.1* My wife and I are in our late 70’s. The ability to monitor the hot water heater using the app is fantastic. When we travel we save money being able to turn the heater off when leaving and turning it back on before arrive home. In addition, having peace of mind with the water leak sensor to cut off the water supply since our heater is in our basement. ### 5/5 — Convenient *2026-06-15, version 6.16.1* It is so convenient for taking care of both water heaters. ### 5/5 — EcoNet Bookworm *2026-06-07, version 6.16.1* Love the app, very understandable, works great. ### 5/5 — New stem *2026-06-06, version 6.16.1* Impressed wit the ease for set-up. Loved that I set via my iPhone. So very convenient. ### 5/5 — Outstanding HVAC Technology and Performance *2026-06-06* The Eco thermostat is, without question, the most impressive HVAC control system I have ever experienced. Its intuitive design, advanced automation, and seamless integration with the entire HVAC system make it truly exceptional. When paired with a dual-fan, six-foot-tall computerized condenser and an air handler equipped with three UV lights, the result is an extraordinarily advanced climate control system. The thermostat continuously optimizes performance, ensuring precise temperature control, outstanding energy efficiency, and exceptional indoor comfort. What impressed me most is how all the components work together as a single intelligent system. The variable-speed technology, air purification features, and sophisticated monitoring capabilities create a level of performance that far exceeds traditional HVAC equipment. The system runs quietly, maintains consistent temperatures throughout the home, and provides excellent air quality. This is, by far, the most advanced and efficient climate control equipment I have ever seen assembled. For anyone looking for cutting-edge HVAC technology, superior comfort, and energy savings, this combination sets a new standard of excellence. Highly recommended! ### 5/5 — Great Thermostat ! *2026-04-29, version 6.16.1* I had that thermostat for 2 years and I cannot say anything bad about it. It works great and I can control it from anywhere in the world very easily. ### 5/5 — Working well!!! *2026-01-21, version 6.15.0* App much better now!! Easy to schedule and control tankless! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
