For the price, the water heater was easy to install, so great water heater. Its been running for 2 weeks without any issues. The issue is this WiFi enabled EcoNet app thing. It just wont connect. The 7-days a week support is true, both times I called on a weekend and got someone on the phone in under 5 minutes. We walked through the setup a few times and they kept saying it had to be either my WiFi password being wrong or I didn’t have 2.4GHz enabled on my router, or even my iPhone or iPad were too new. I confirmed my password, 2.4GHz, and well my iPhone is 2 years old, so the first tech admitted they have been getting alot of issues like this, took the mac address of our unit and said the issue woukd be escalated and dealt with in about 2 days. I saw the ticket was closed 2 days later but still couldn’t see the device in the app. I called a week later and the tech confirmed that the ticket was closed, but eould reopen and escalate it. I’m going to check again in a week. I’m assuming this feature works, so I’m going to call them again bext week, but it is frustrating that they aren’t able to deal with this issue. So I’m giving the heater 4 stars, but the app unfortunately is going to get 2 stars, but it might not be the fault of the app. If I can ever get the device to connect I’ll edit the review.

Installed new Rheem heat pump and heat pump water heater. The appliances are great, with the heat pump almost keeping up with our old, leaky house in -25° C weather this week without even resorting to resistive electric backup (and no problem with the resistive electric providing a small boost). The app is barely serviceable. Connecting to wifi was a huge hassle; finally got it to work after weeks by turning off home wifi, changing my iPhone name to that of the home wifi network, and setting up the thermostat using a hotspot. Then disabling the hotspot and re-enabling the home wifi once the thermostat knew the name and password made everything work. Now that the thermostat is connected to the app, the app does the bare minimum: it shows the current temperature in the house, the set point, and gives me the ability to control the schedule. It does not display anything beyond the most basic data: doesn’t show the outside temperature from the sensor on the heat pump (crucial information for a heat pump that a weather station temperature from the internet doesn’t provide), it doesn’t say whether the resistive heat is turned on, and doesn’t say the current fan speed. Also, there’s no history information. For the water heater, it shows the setpoint (and has energy consumption history, which is great), but not the current temperature. No HomeKit support (not a big deal to us, but might bother others). We are told (but haven’t verified) that we cannot use a third-party thermostat or app with the appliances, so no choice. Summary: appliances are great, and we have eliminated fossil fuel energy in our home in favor or hydro and solar electric power. App lets me use the basic thermostat functions from anywhere, which is the bare minimum I expect from an internet-connected appliance.

I’ve had Rheem’s ProTerra Hybrid Water Heater installed for about 3 weeks, and though the basic water heater is good, the ‘smart’ features are terrible, as is the customer support. I’ve now confirmed that the scheduling functions frequently don’t work, and can’t be corrected or disabled through the phone app when this occurs, it has to be done manually on the heater console. I’ve had a problem report in to Rheem for days, with nothing except an automated response. If you just want a water heater this is a good product, but Rheem doesn’t have a clue about software development or customer support.Update: Was unable to connect the app at all the other day. App behaved as if there was no device registered, and got stuck in a loop trying to enter a new one. Finally got to customer support by phone and was told they’d had a server glitch and the account had to be re-initialized. Support guy was pretty good, but all history was lost. Now things appear to be working better. We’ll see…

I got the Rheem 50gal Hybrid Electric water heater and after reading these reviews I wasn’t even going to bother with the app, but eventually I though let me try it out. It’s worked perfectly for me since day 1. Setup was simple enough, and the schedule I tested and it works. Just set it to a time and mode and temp for the time and day you’re on and once you hit follow schedule it should change immediately. Key step there, seems some people did not hit follow schedule and so it’s not working. But either way it’s working great for me. Even when I out away from home and someone at home needs to shower and do laundry and maybe my tenants next door are doing laundry also, I just open the app, turn up the temp and change the mode to electric or high demand and once I get home I look and the actual heater and it says what I put it on the app, so it does work.
