Superbly satisfied
The app based water temp adjustability is truly awesome. I’ve had this performance platinum gladiator for about 5 months and love it. I had a houseful of guests coming, turned up the temp from the couch, we never ran out of hot water, when they all left I turned it back down. Then I turned it way down while packing to leave town for a week, turned it back up when I got back home, and never touched it. Very happy.

    Good value and nice features
    The water heater is very well made and insulated. Because of that and the 5500 watt heating elements I was able to step down from a 50 gallon to this 40 gallon electric model. I like the information and control available through the app on my iPhone. The installation is no more complicated than a dumb model and actually this unit is nice to look at. You say why does one need a WiFi model? and I say you don’t need it it’s just helpful to have the extra information. Couple all of that with a 12 year warranty and 3 year in home warranty and this heater is a bargain.

      Piece of JUNK, do not buy unless you like headaches and cold water.
      I installed the gladiator hot water heater in my garage 9 days ago and it has been nothing but a pain. The A102 alarm will go off between 8pm-4am like clockwork. I have to reset it every day, if you don’t you will be left taking a cold shower. There is NO leak or water ANYWHERE on or near the water heater. I contacted HD to see if I could return it, but they said after one day you have to deal with the manufacturer. I contacted them via email and have heard nothing back…ugh. The LeakSense feature is really the Cold Water feature, it will save you money by always shutting it down. I will NEVER buy a hot water heater with this feature in the future unless there is a way to disable it. If there was a button to turn this feature off permanently it would be great, but there isn't. I’m going to see if there is a way to hack it, to disable this headache. If not, I’m going to eat my $700 and get a water heater without this feature. I replaced a 15-year-old tank because it started to leak. I never thought about it until 5 days before I replaced it with this Junker. With the Gladiator, I think about it every day or I won’t have hot water. This is a waste of my time and mental overhead, I hate it soooo much.

        Defective units out of the box
        I purchased this water heater on 6/8/20. Immediately after install, I noticed some water around the pressure release valve and the sensor went off. In the instructions for install, they say some water may spill and so I over-rode the shut off, tried to dry the area, and waited it out. The alarm went off a few weeks later and it was the same issue. I waited a few more weeks to see if it was just a fluke and when I went to check on it in August, I noticed a ton of corrosion by the junction box. I called Rheem and they contracted a plumber to come take a look. He tightened the T&P valve but the very next day there was standing water where the anode rod was. I called Rheem again, and the plumber came to replace it with a new one. Literally within 5 minutes of installation, there was water coming out of the base of the T&P valve as well as one small hole at the top of the unit. The plumber said this was ridiculous and that in no way, shape, or form should this be happening. So now I'm awaiting my third water heater of the same model.

          Very good water heater, more than enough for thee 2 of us, We even get through a few hours of powered off hot water during peak times, we have off peak water heating. The wifi app is great, and offers easy control of the device. Delivered well, and it was professionally installed by TCC Plumbing and Heating. We are very happy with this purchase so far.

          I choose this water heater for the following reasons: Brand, Warranty, Leak Detection, and most importantly WiFi enable (smart water heater). So far I like the app (EcoNet) shows pretty much everything i need to know about the water heater, health, hot water availability, usage (Daily, weekly, etc), and schedule. I have not played with schedules yet but I will. Shipping was fast and it came undamaged. I did have to buy the drain pan, Stainless Steel Corrugated Water Heater Connector. The Installation was pretty easy (DIY's) once I have emptied and removed my 20 years old water heater. Initial power on and the WiFi setup was also pretty easy just followed the steps on the quick start guide. It has been only a couple of weeks but so far it has been working great.
