Rheem does not define this icon behavior anywhere. This jumps frightingly when the Element come on. on inspections schedule, non-contact / padded blocking restraints) Or the app? Any idea on how to resolve it? Might be that concealing it possibly shields Rheem/Rudd from issues reported by the consumer. How'd it work out? 3 Electric Only this turns off the heat pump. Is there a date code or other indication to know which ones to avoid? Hi. I can confirm there's a quality issue with the 5th Gen hybrid water heaters. I can hear the compressor, but it's not deafening as I've heard in some YouTube videos. wish there was user-accessible data on top-middle-bottom tank temps!). I hired an electrician to add a subpanel and run a 220 VAC/30 Amp circuit from it to where the HPWH would be located. Any feedback on whether the 2022 model is quieter (or at least acceptable) would be very helpful as well. Also going to add some dampening material to the wall. Required fields are marked *. Heat pump only mode is the most efficient mode but offers lower recovery time. My Rheem 80G was $1600 + 75 delivery to my back door, and I had $600 NHsaves.org rebate. Jonathan you may want to consider filing a complaint form with federal Trade Commission FTC. So now I have no hot water expense now and no gasoline expense as drive an EV for transportation. Something that bit me when installing a Professional Prestige ProTerra 80 gal is the noise it generates. I am also considering the Chiltrix CX34 which is a "split" system like the Sanden, however it only has a max temperature of 131 F due to the thermodynamic cycle of its refrigerant choice of R410a, so it wouldn't be as useful at storing thermal energy during the 3-9 pm off time. Tap on the start or end time to change it:if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[250,250],'askdavetaylor_com-medrectangle-4','ezslot_8',108,'0','0'])};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-askdavetaylor_com-medrectangle-4-0')}; Got it all just so, with your exact start and end times ready? Insert a small flat-head screwdriver into the slot on the thermostat dial. 2 Normal is the same as energy saver but gives the heat pumps less time to its job. Ray (I guess ^), I assume you have wifi; you can set the temp to 110, then put it up to 140 a day or 2 before they arrive. - ducting Don't know if this was due to app updates or some other reason. unit set to Heat Pump Only at 110F. According to this patent you have 3 options. That is, every 6 hours, 140wh are used even in that OFF mode. But I want to schedule vacation mode and cant figure out how to do so.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[468,60],'askdavetaylor_com-box-3','ezslot_7',125,'0','0'])};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-askdavetaylor_com-box-3-0')}; The first and most important step is to make sure you have everything set up, including the Rheem app on your smartphone. How Can I Change Security PIN on my Android Phone? I am NOT happy with the temperature control hysteresis, it allows too wide a drop before restarting the heatpump. After following 3 different forums, people are reporting that Rheem has solved the noise issue on the units manufactured after Jan 2022. Yes, the app is underwhelming. Not sure what the cutoff temp would be that causes heating elements to kick in though. I also have a PV system with an eGauge, so I can see real time energy use. Then I also have days where I define to not heat water at all where I set the usage mode to be OFF. 10am = 145 F (or max) Also, it is a 1924 vintage house with single pane windows, and a fair amount of opportunities for drafts it is *not* a modern airtight living space. evening; other HW uses mostly off-peak mornings. It also can be set via timer, not sure how many timers/day, but you basically only need 2, 110, and 140. I have the XE80T10HS45U0 purchased online from the 'Orange' big box store on 3/28/2022 and received a unit with a production date of "08MAR2022". How Can I Properly Change Default Web Browser in Windows 11. Id like to understand what is going on and to not have it do this, as I am OK with longer recovery times in order to save energy. I spoke to one installer and was told the supply houses receive batches of HW heaters all having the same manufacturer date. Is there an affordable/recommended 240V equivalent to the Kill-A-Watt meter (plug-based) or would I need an Ammeter (clamp) or even hard-wired-in data logger? The point is, no matter what, every other hour energy usage time slot is ALWAYS zero and this is when I validate that the compressor ran without stopping for 3hours straight. vs. more storage if better mixing)? Our gas bill is nicely down. The AO Smith blended resistive with different set points for activation with the HP and resolved draw down demand with an 80 gal. You'd think Big Box Store would have both available (though ordinarily I wouldn't go through them for install), but they just said they didn't do installs on hybrids at all. Maybe you could find another way to pre-warm water before it gets to the HPWH (like a passive buffer tank or drain water heat recovery). I've attached the data I sent them. Further, please note that by submitting a question or comment you're agreeing to our terms of service, which are: you relinquish any subsequent rights of ownership to your material by submitting it on this site. I did a warranty replacement, and the replacement had the same problem. It is one of the most obvious pieces of information you would think that Rheem would provide, but they dont. Wow. Or is there a way to automatically once a week or once a month to heat to 140 just to kill the bad germs? Anyone have a clue as to the difference between "heat pump only" mode and "energy saving" mode? The architect, builder and I didn't have experience with them so we didn't catch it before construction. You must be a magazine subscriber to access this feature. Lots of buyers feel let down that Rheems heat pump water heaters do not provide the current temp of the water. This was installed last year during construction of a new house where, unfortunately, it was installed against an interior wall. I'm deciding between this Rheem unit and a Sanden Eco2 (formerly SanCO2) because I want to be able to schedule them to go to max temperature just before peak electricity rates kick in (in Oakland, CA on PG&E this is at either 3pm or 4pm depending on standard or EV rate schedule). I am NOT happy with the Econet application for its lack of displaying the live temperature sensor data and it's lack of browser support - why the heck does everything need to be an app?! I randomly stumbled back on this question from 2019. I am installed and only using HP mode, I take 4 showers a week, plus 1 load of laundry. I would love to know if this is happening but not easy to keep an eye on the heater itself The bottom line is I am happy with my heat pump water heater and can validate that it saves me significant money compared to natural gas. 10pm = 120 F I run the water heater in heat pump mode for maximum efficiency. Does High Demand ever use heat pump? I may add a vent from the garage to the outside if I think an air pressure differential develops. ~4 showers per week. Follow me on Twitter Do you know if your furnace uses sealed or atmospheric combustion. Please read on! 4. Harsch received her Certified Nurses Assistant license in 2004. Do we not care about the 30 feet of hot water pipe to the shower head? They told me to wait for the next App update which they were told would be released next week and that was 3 weeks ago. Is there some advantage to using Vacation Mode, as opposed to turning off the water supply and cutting the power at the breaker? The attached picture shows mine during installation, before further support, insulation and condensate line. 3. Still nothing. A question: did you get your Performance Platinum? 11pm = 125 F. So, basically, using the Rheem's max temperature of 145 F as thermal energy storage and coupling the output to an anti-scald tempering valve that regulates the output temperature to, say, 125 F. The Sanden unit would be even better at this because it has a 120 gallon tank option and claims to go as high as 175 F due to the CO2 refrigerant supercritical thermodynamic cycle, however it looks to be $2K more expensive with fewer systems installed which makes me worry about service when something inevitably goes wrong. I am actually surprised that you obtained as much info as you did from the Rheem techs. We take great care to provide quality information. You can see that I have no vacations set up. This will give me a bigger, better, buffer. Theres a bunch of information online about how to do that, but from my own experience, its pretty straightforward. Rotate the thermostat to your desired temperature. Slightly less noise than the GE GeoSpring 50 that I replaced. One I encourage everyone to consider is having a bidet. It's so bad we might put it in electric mode during the daytime, if it doesn't need to run very often. I didn't have any issues w/recovery in heat pump mode vs. energy saving. Here in NH we have flat rate electricity, but I do have Solar. When you're paying up to, virtually 50c/kWh, it's amazing how much you can save with off-peak usages and heat-pump only modes. Home Depot's Halt on Rheem Hybrid Water Heaters. The utility room is 840 cubic feet (just measured). Is a 2022 unit with a noise fix? So this is how my installer purchased my unit. I suspect the control works this way to minimize complaints about slow recovery times. Highly recommended. So this installer told me that he could solve my AFTER Jan 2022 requirement by going to the Orange box store instead. Will that step make your showers 100 percent safe against a respiratory infection? FWIW, my hybrid was (and still is) set to 140 degrees, which may increase the need for "prewarm?" I did check our electrical capacity at the time and there was plenty for a HPWH, but since then we've put in a heat pump furnace, so I don't know offhand how much is left. Neither situation being practical/realistic, but I can still nudge usage towards production ours with pool pump timers and the Hot Water heater], "however it looks to be $2K more expensive " How Do You Remove or Delete Apps from a Chromebook? [I did the math. - damping in wall (be careful about how dense/contact w/both sides), The noise is across a range of frequencies so may need a range of solutionsboth light and heavy materials, Final tip: I have mine set to run up to 140degF by 3pm when I (in normal times) am not home, then coast until the next day (mix down to 120 w/valve). I checked the alarm history and there is just an alarm for not connecting the water leak sensor (which I elected not to use in my install). Like William Morse, I suspect you are over thinking it. If there is a sensor issue (A101, A102, A105, A106, for example), the HPWH with switch to the electric element. If it is in energy-saver mode, the heat pump and electric element are active. Follow me on Instagram. The space is fine -- we have a good-sized unfinished basement. Fan is very low noise, and while I can hear the compressor, I wouldn't consider it bothersome. In any case, I have CO detectors. I read these heaters loose 1 degree per hour and I doubt this loss is linear. Can you also check your alarm history? document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Follow Me on Pinterest OSHA says 140 degree water kills legionella after 32 minutes. Here is an example of the idea (assuming 3pm - 9pm as peak rate hours): 7am = 130 F Nor a resource to find out. Does anyone have a sense of when the heat pump would struggle and trigger the resistive rods to kick on? I recently had a 50-gal Rheem Hybrid water heater installed. Hope thats at least a little usefulgood luck and let us know how it turns out! I have such a setup and with the Proterra hybrid water heater in the recommended ES mode it appears to be delayed in energizing the compressor ( the hot water availability drops to 1/3 or less per the app indication). The garage 1125 cubic feet. Also the patent makes it clear regardless of the mode selected the resistance element will come on after some unknown time period if the heat pump fails to reach the set temp before the timer runs out. The Rheem unit uses R134a refrigerant like the modern USA automotive industry, so it cannot get as high as the Sanden CO2 solution but they claim to be able to reach 145 F on their datasheet. Still unsure whether Hight Demand is auto-all-electric or heat pump might kicks in though? The app can be used to plan for when you want the unit to heat the water via a time-window scheduling schema based on the day of the week. My use case is 4 adults full time (3 shower heads) with an occasional extra 2 adults. Does it keep the water at 55 degrees? Set on Heat-pump only, it never uses the rods. Follow me on LinkedIn 2022 The Taunton Press, Inc. All rights reserved. There are many harmful bacteria that can survive and multiply at 110 F. I may switch to a simple time-of-use plan where the delta between peak and off peak is more like 37 cents vs. 27 cents. NO major noise issues. May try narrowing 140F window to reach temp closer to 3pm to reduce standby losses (at potential loss of capacity? Solar is good and my system will be paid for completely in 2 more years. Rheem says the utility room has to be at least 700 cubic feet and ducts have to be between 5 and 8 inches. My home is fairly new, so adding the subpanel and circuit was a fairly simple process. If your unit has a fault the app maybe trying to get you to enable the element to hide the fault until the warranty expires. Energy Save mode, what criteria push it into electric element mode instead of heat pump? I agree that running the tank at 140F+ a few times a year is a good practice to kill any possible legionnaires bacteria. The fact that you are getting a pre warm message means your tank has cooled below the unknown pre warm temp. I have the Rheem 80-gallen hybrid heat pump water heater. I routinely change the Rheem from 110 to 140, after being at 110 for hours or days. I self installed the 80 gallon model using pex and sharkbite and a self installed sub-panel. Can you double-check your settings? Is It Possible to Translate a Microsoft Word Doc Into Another Language? As in not regulating the temp at all? Is it worth it financially, and/or environmentally (total energy use) (2 sep.?s), to bump up to 140F and have more standby losses, vs. just leaving at 120 and letting it run if it needs to (given only 40gal)? And it would allow for safer (bacteria) core temps yet avoiding scalding. Just noticed (after daylight savings time shift?) Thanks for any info you can provide. Are Expensive Building Components Necessary? Any update on the 5th Gen Rheem noise issue. @ C Z - by 'status screen' do you mean the screen on the water heater itself? On the Status screen, it says pre-warm status. At the same time, every 6 hrs, the info shows I burn 140wh of energy and this includes days where the Rheem is OFF for days on end. But I didn't see anything in the use guide about colocating a HPWH with other appliances. Of course, you may never use the heating element if the unit stay in heat pump mode. 9pm = 110 F We have an 80 gal. I'm about to install temperature valve (factory set to 120, hard to go above) to allow me to safely heat extra to say 130 and when the sun shines. (will also ask PEC tool library in SF) Worth installing heat-recovery on shower to keep HP off until morning on 2 shower evenings? That's what I would buy if I had to do it over. Thanks for the pointers. Never miss a single article, review or tutorial here on AskDaveTaylor, sign up for my fun weekly newsletter! In 60 deg basement air, with the cold output air vented to the outside, my first month usage of just about every other day of water heating, I used 37Kwh of energy which is slightly more that one day of solar generation for a month. Then download and set up the Rheem app, entering both values when prompted, and you should be good to go, with your water heater showing up in the app itself.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[580,400],'askdavetaylor_com-medrectangle-3','ezslot_1',107,'0','0'])};if(typeof __ez_fad_position != 'undefined'){__ez_fad_position('div-gpt-ad-askdavetaylor_com-medrectangle-3-0')}; If thats all good, then launching the app should show you something like this: If you arent seeing your device, go through the setup steps again until you do see it show up (notice mines Gas Water Heater in Basement on the lower left). I look at consumption chart in the app and did not notice any outliners when using Energy Saver mode with recirculatory pump though. I then set it to High Demand 138F on weekends when guests arrive, so they can mix with cold water to make hot water tank last longer if they do multiple water jet tubs simultaneouly. Then I want to schedule their temperature setting to be so low that the heater won't turn on unless we have a full house of guests visiting for a rare holiday or similar, and then turn back on after 9pm when the electricity rate schedule gets cheap again. Nobody wants to burn a 140 watt lightbulb for an hour, every 6 hours no matter what. 1Energy Saver that only turns on the heatpump after the element as somewhat warmed the tank and will turn on the element is the heat pump takes too long to warm the water. Does the app tell you the temp of water in the tank, not just the set temp? To accomplish that handy trick, go back to Settings: Tap on Works with Nest, and, well, sign in to your Nest account: Went out on vacation for the holidays, before leaving I set the heater on vacation mode as I always do. Slightly less noise than the GE GeoSpring it replaced.
