The Rheem EcoSense 50 gal. Hybrid Heat Pump Water heater is the most efficient electric water heater in its class. The integrated heat pump module removes heat from the surrounding air and transfers it to the water inside the tank. An energy factor of 2.45 reduces operating costs by $329 annually when compared to a standard 50 gal. electric model. Incoloy stainless steel elements provide backup heating capacity during periods of high demand or when ambient air drops below 37 degree F. The water heater features a full-color touch screen LCD display with intuitive controls and diagnostic capabilities. A 240 volt electrical connection is required for installation. The patented magnesium anode rod design incorporates a special resistor that protects the tanks from rust, providing longer tank life. Factory installed temperature and pressure relief valve and 3/4 in. water connections are included with the water heater for easy installation. This model has a 12 year limited tank and parts warranty plus a 1 year in home labor warranty. This Rheem EcoSense Hybrid model is Wifi compatible allowing for remote monitoring of the water heater's operation (WiFi Module REWRA631EWH sold separately).

Rated 3.4 out of 5 by 43 reviewers.
Rated 5.0 out of 5.0 by Great water heater Installation was very easy and straight foward. As long as you have somewhere to put condensate, it is no more difficult than a regular water heater install. With 2 people using the water heater, you can easily get by in "Heat Pump Only" mode. When I have a lot of visitors, I crank it up to "High Demand" mode to get maximum output. I didn't have any issue with my heat pump failing, but I made sure to keep an eye on things and never allowed it to be layed on its side. The actual heater empty is about 160 lbs or so, so it is easily moved around with a hand truck. The heat pump is about as loud as a window unit A/C, but is obviously only running when the water heater is heating the water. In a garage in Florida, it is nice to have something bringing the temp down a bit. I can't hear the water heater from inside my house, but it might be a little loud for somewhere you spend a lot of time (like if your water heater is located next to a bedroom). I also have the EcoNet Wifi adapter. The app works OK, but tends to crash. Ultimately, it does what you need it to do. It is no frills, and doesn't offer the same information you can access from the front panel of the water heater (such as temperature levels). It is limited to just temperature setting, and mode.

Rated 3.0 out of 5.0 by Rheem hybrid heat pump water heater, Compressor not working company does not have fix I have installed my water heater it was fairly easy.But energy saver and heat pump only mode send it in to an alarm shut down mode code A004 compressor suction trip.So I called the 800 # and technical support said the company knows they have an issue with this problem but has no fix for it. They will let me know when they do ,I'm on their list so for now it is in electric mode only. It heats water better than my old electric only heater, but no energy saving yet. November 7, 2013
Rated 1.0 out of 5.0 by DO NOT BUY THIS WATER HEATER I should have paid attention to all the people who wrote about all the problems with this water heater. They were correct. Immediately after it was installed it failed to operate in the Hybrid Mode. It did operate in the full electric mode and did keep us in hot water until it was replaced. But I could have ordered a nice regular (energy hungry) hot water heater for $ 300 or $ 400 not $ 1,200. I contracted Rheem and they diagnosed the problem over the phone. The Heat Pump unit had failed and they gave me a return authorization order. Home depot would not order a replacement unit unless I paid for it in advance and then they would accept the defective heater and issue me a refund. I went back and forth with first the local store manager and then the return department at Home Depot about how absurd it was that I had to shell out twice for a defective heater, didn't work. So I paid for a second heater waited three weeks for it to arrive. I did convince home depot to have the water heater delivered to my home and put in the garage at no charge. Then I had to pay to have the old heater removed and the new one installed. This was after I had already paid to have the first one installed. Rheem did reimburse me for the 2nd installation ( their max is $250) after I sent them all the documentation. This entire saga took from early February when I received the defective heater until Mid April when the replacement was finally installed. So I had to go through two installations, hours visiting the store and on the phone with Home Depot and Rheem and in general a lot of aggravation. The worst part is the replacement heater although it does work in Hybrid mode is so loud I doubt we will ever use it that way. It has to be installed in a temperature controlled area to operate correctly so the noise can not be escaped. So I am stuck with a $ 1,200 water heater I will never use in Hybrid mode!! DO NOT BUY THIS WATER HEATER May 5, 2015
Rated 4.0 out of 5.0 by Quality Water Heater A quality water heater. I had a local plumbing company install, just to avoid future issues with pipes. Install was smooth and fast. Had hot water within about 30-45 minutes of turning the unit on. The fan on the heat pump is a little noisy, but since it's in the utility room, I don't notice it. An occasional whirring is worth the cost savings. I imagine the savings would be maximized in a hotter climate than up here in Alaska. Also, the touch screen is very responsive and easy to use. I will try to update this review when I get my next electric bill (for comparison). April 12, 2014
Rated 1.0 out of 5.0 by Great water heater in theory, terrible software! Almost a great water heater, but software fails miserably. The heat pump function works great, heats up water perfectly to temperature in a reasonable amount of time. It definitely makes noise that you can hear despite it being in our basement, but this is tolerable. The problem? It doesn't trigger to reheat unless there is demand (i.e. you turn on the hot water and run a few gallons) or there is a 20 degree drop in temperature! So if you shower, leave for a day, and want to shower again when you return your "hot water" could be at 101 degrees assuming your water heater is set to a standard 120. This leaves you the option of overheating your water or having to remember to turn on hot water intermittently so that the water is hot when you want to shower. Neither of these options are reasonable. We called Rheem and they confirmed this is what the specifications are, and there is no way to change it. Until this is changed I would highly recommend against purchasing this water heater. June 10, 2015
Rated 5.0 out of 5.0 by WOW! WOW! Is the one word I can use for this product. Installed in less than an hour, and was easy for a person that is somewhat mechanically inclined. Have had for about a week, and could not be any more happy. Plenty of hot water for a family of three, and my wife likes 20 min showers. The compressor is not very loud at all, and the unit seems to be very well made. Display is awesome, as it shows you a whole lot of information. I am looking forward to many years of use.

Rated 5.0 out of 5.0 by Just installed... Nervous about the purchase after reading the problems. Made sure NEVER laid down after receiving. As with any large purchase through Home Depot, it was frustrating. Ship to store took only a week, even though said two. Brought home and unpackaged. Unit appears to have been removed before. Three brackets hold down heater to box/skid - two were removed and bent with it's screws jammed into the cardboard bottom. The owners manual plastic pouch was opened from the top. This made me more nervous as it now appears I have purchased a returned or reman'ed unit for full price. (1,199). Home Depot DID HAVE this exact model available online for two prices - one for 1199 and the other was around 984, but the other is no longer on the site. Anyhow, now to the water heater. The manual is disappointing. No info for warm-up and what to expect when first started. You will need to expect that the heat pump/comp will do nothing for quite some time until AFTER the UPPER element, then LOWER element heat for about an hour or so, bringing the water temp up from my cool well water temp of about 53+ degrees to around 120 factory setting at the upper sensor. THEN the heat pump will kick in. (When first powered, we worried why the heat pump/comp wasn't coming on, but after checking the SERVICE menu of the touch screen, and then the SENSORS submenu, we saw it was actually heating with the upper element and performing a WARM-UP procedure). The touch screen is super easy to use and informative as to the current status and temperatures of the various sensors. It first heated using the upper element- from 53 to 118, then turned to the bottom element, which was still 53 degrees and began heating. (the electrical meter outside was spinning quite well at this time). BUT...then the heat pump/comp came on after heating the lower for a while to about 90, the meter slowed to about half as before AND then the heat pump/comp ran for about 2 hours or so before shutting off. As far as noise - NONE from the electrical heating, but the heat pump/comp has the sound of a window air conditioner when running. Perhaps quieter than one as far as decibels, but similar. Thankfully, it's installed in my basement utility room, so I don't have to listen to it, but would probably be a bit annoying if you had to be in the room next to it for a while as it was running, especially trying to sleep within the next room. Don't know yet how often it will run the heat pump/comp, though. In comparison, I replaced a power-vented propane heater with this and the heat pump/comp is just a bit louder than the power vent motor running. When the heat pump/comp was running, I noticed the sensor reading for DISCHARGE TEMP increased to around 168 degrees+. The water was VERY HOT and pretty much scalding if you left your hand there. I would consider this a success, since the purpose is to get the water hot after all. I'm looking forward to seeing the REAL savings in the electric bill. I had propane for about 600-700 annually, so if the energy guide is anywhere near accurate at 215 annually, this hybrid heater will pay for itself quickly. I will update this review after further experience if any problems arise. If no updates after a long time, then consider the follow-up to be quite positive! October 18, 2014
Rated 4.0 out of 5.0 by Purchase situation deceptive though I still bought it. Very upsetting. Cost nearly as much to install as to buy it due to piping for condensate lines and the rest. The unit itself is fine however there was much about the presentation that left a lot to be desired. April 28, 2015
