Stiebel eltron tempra 24 plus water heater is compared to a conventional electric tank water heater, a water heater will typically use 15-20% less energy, although savings can be substantially higher depending on usage habits. conventional electric tank water heaters continually store hot water and as a result lose 15-20% of the total energy they consume to the environment around them. this is called standby heat loss.

Reviews:
I was hoping for so much from this product. Yesterday I took such a hot shower during lunch and then that evening when I gave my daughter a bath, it only came out lukewarm. My shower today was borderline cold. Tomorrow it may be hot again. I live in Northern VA and would not recommend this product. It ruins the experience of our new bathroom remodel. There's nothing worse than remodeling your bathroom to your dream bathroom and hearing your wife say, well that bath wasn't relaxing since she couldn't get hot water.ChristianMC
We purchased this unit about 1 month ago, replacing a Natural Gas water heater with 40g tank. The savings in space, and the removal of the fossil fuel device were our key drivers for this purchase. Our Electric bill has increased significantly, by about 50%, but because we never run out of hot water, showers tend to be longer. And now we can actually fill our tub with hot water without boiling extra water on the stove, so this also has increased our usage. There is an issue with temperature stability, when a toilet is flushed or other demand for water is turned on, the temperature swing is very noticeable. I have added a shower temp gauge, and have seen the temp drop from 42c to 39c when a toilet is flushed, it takes about 10-15 seconds to recover, and likewise, when the water demand drops, the temp goes up from 42c to 44.5c for several seconds. This shower valve has a pressure regulated flow control, so changes in the water will take some time to correct. Pros: Save on Space, endless hot water, retired fossil fuel appliance, not storing heated water we aren't using. Cons: High electricity costs, temperature changes when pressure changes for several secondsChris
Don't buy it…it's terrible,I bought the tempra24 plus from home depot, I installed all specified wires and circuits so it would work properly and efficiently but this this is horrible… my electric and water bill did go down even more than I had Anticipated but hate it…No constant temperature what so ever. I'm getting it removed and getting one installed by a professional.. the tempraplus was a waste of moneyBrian Lackie

Reviews:
It works fine, but it arrived in a shipping box with no manufactruer box inside, just the water heater. One of the dials has come lose and I had to screw it back on. There was no manual. There was no power cord, but it may not have come with one ( I couldn’t tell you since I didn’t get a box or a manual). There was water inside the unit. I think someone must have gotten it before me and then returned it and factory pure didn’t notice- that or the falsely sold me a used unit. I went ahead and installed it, though, because I had already opened up my water line and removed the old unit. If anyone from factory pure is reading this, I’ll forgive you for a fifty dollar partial refund- that’s about what I’d have expected to save by buying used.cade j.
As for the breaker tripping in other homes, as a licensed electrician of 26 years, I would advise you to take an amperage reading during operation. Most home owners do not have multi meters with an amp clamp so that could be difficult I understand. If the heater is not drawing over 55 amp during operation you may have a defective circuit breaker, it happens. Try replacing your breaker. If the heater is drawing over 55 amps ther is a problem with the heater.Andy A.

Reviews:
Like all of the 1 star ratings, my unit failed after about a year. It began leaking which caused it to short out. When I called the customer service, they asked for pictures of the leak and the heating elements. They immediately blamed the leak on me for not maintaining the unit. After I prove I did they asked me to send a video of the unit tripping the breaker which made no sense considering the unit was leaking water. In the end they recommended I re-solder the hole. Really?! So, for the sake of having hot water in the middle of winter, I do. Nine months later another hole appears and the exact same issue occurs. This time I demand a replacement after once again being blamed for the issue. After they run out of excuses on why it happened they then say I never registered my warranty, which I did. How in the world do I prove that I registered my warranty when the same people I registered it with claims I didn't? This product has NO support if and when it fails. STAY AWAY FROM THIS COMPANY!! Buy a better unit for a little more money AND keep all of the warranty information just in case.Andre'
To use this unit you will need to have an electrician bring in 3 high voltage lines into your home. $$$$. Any time you use the unit all the lights in the house flicker. After months of that annoyance I contacted dealer and was given a new control panel that I had to install myself. It solved the problem for a couple months then back to the flickering. Two years later the unit just stopped working. Plumbing service call told me I needed another new control panel. Now company says I don’t have lifetime warranty because I didn’t send in warranty card. They claim That they sent me replacement last time as a courtesy. This company is so short sited, they probably paid staff to argue with me more than it would have cost to replace the part. I bought a new part and had it installed…..back to the flickering lights. And do not buy this thinking you will cover the cost with savings. I’ve seen no difference in my electric bills. Read some other reviews. It’s not just the control panel that is garbage.Val
The first couple of months this product was awesome. Water was super hot and was easy to adjust. Then we noticed the water would not get as hot. Adjusted temperature on unit to 140 degrees, removed the filter off end of kitchen sink and nothing happened. Went through the virtual tech guide multiple times and found heating element was out. Tech support shipped a new one. Installed it, no change. Call back and was told you have to soak the heating elements in vinegar for 2-3 hours every six months. Reluctantly did it, no change. Even had it worked you should not have to do maintenance like this on a product not even a year old. Have had experience with other tankless heaters and never had to do maintenance. I've requested a supervisor call me 3-4 times and have yet to receive a call back. This has been going on for two months. Do not go with this product. Product quality is poor and tech support is as well.Daniel Andrews

The Rinnai is very quiet. I really like that. I dont hear it like the water heater I had. Its small. Not this large ugly gas heater that takes space away. I save money. Does not run every time you use hot water like the old large water heater and you could hear the old style water heater heating the water every time you used hot water. You have the choice of gas or electric. I have gas. Should have invested in this product years ago.Butterfly7926

Reviews:
Easier to install than removing the old tank unit. My wife was skeptical at first that this would be as good or better than our old unit with the idea of "unlimited" hot water and it didn't disappoint… We have a small house but both showers and washer can run all at the same time..actionmaytag
This water heater is perfect for my little house, endless hot water. Was somewhat of a challenge to DIY install but I made it happen. This unit drinks lots of power. Be sure you have room in your panel. Shark Bite fittings with copper plumbing is essential, much faster. Would definitely buy this again.rdricker81

Reviews:
I've got a large house and more children than most. This unit produces sufficient hot water to run several showers at once and never run out, which is the main point. I'm very pleased with this unit. There's one oddity however; When first starting-up, the water temperature gradually increases until the set-point arrives at the delivery spot and holds there for a few moments, then the temperature wanes to lukewarm/cool, then back to specified temperature. This can be quite a jolt to the system if the user isn't prepared 🙂 But the change is gradual enough to get out of the way in time. This is annoying. The display alternates between my chosen set point "130 F" and "E5", which I assume is an error code. But none of the online documentation provides an error code key from which to ascertain the issue. I have two three-way valves in my installation which allows me to run my system in tankless only, tank only, or tankless preheat followed by tank. In the summer I run tankless only, in winter I typically run tankless as preheat and draw from the tank unit.Engineer Dude
i had it professionally installed and its keeps popping a fuse and stops working all the time . i think it finally completely failed after 1 years of use only and 900 later. i home RHEEM will send me replacement as its under warranty. but seems liek its one of the worse ones to have. all bad ratings. i would like to upgrade to a better one.asta

Reviews:
I self installed the unit a week ago. Since my existing electrical panel only had room for one double pole breaker I had to install a 100 amp breaker and run to a sub panel for the two 50 amp breakers required for the unit. I was able to mount the sub panel and the water heater on the wall in the space formerly occupied by the tank heater. I also installed a sediment filter on the input side of the heater. The installation went smoothly and was completed in less than a day. So far the unit is supplying plenty of hot water for my wife and I. We are able to take long, hot showers with no drop in water temperature or water pressure. It can also handle the dish washer and the washing machine, but not at the same time. The unit is well constructed and the installation instructions are good. Total cost of the unit, sub panel, breakers and other fittings came out to less than $800. All and all we are very satisfied and would recommend this unit for any household with similar requirements: 2 people, dish washer and laundry. Three or more people may require a larger unit.
I used this for radiant flooring with nibco panel and it works great..heating 1600 square foot house perfectly..frgay7427_g8dwpezoy

Reviews:
Nicely made unit. Clean lines, nice display, lightweight, easy to mount. You'll need a terminal box to wire it up since it comes with it's own pigtail cable (they don't want you to open up the case since it will void it's warranty, apparently; multi breaker units might be different), so I bought an inexpensive 60 amp A/C unit type cut-off switch box with a pull out switch. Just mount it near the heater on the wall and run your 6 gauge wire to it from your breaker panel. I just wish they had included adapters so that you can plumb it to 3/4" piping, so you'll have to buy your own if you wish to connect it to your existing 3/4" pipe. I had trouble using pipe dope (maybe it was too old or the wrong kind?), so I switched to Teflon tape (5 layers) on each fitting and that did the trick. Love the easy to turn dial, press to turn on/off feature and easy to read digital display which comes on when hot water is called for. Now, we'll see how long it lasts before some type of failure…scottcollins
so just got this unit instated and replaced 6 years old Titan (220watts)that just hasn't been getting up desire temperature lately. read bunch of reviews and this unit had better ratings . it was easy to switch from old unit as water and power hookups are almost the same . tested and it want keep up with fully open single sink , I had to reduce water flow at inlet pipe . did not measure but it seams im getting aprx. 2 gal a minute. no way to use 2 outlets at same time. btw we are in coastal northern Washington stateromanles

Easier to install than removing the old tank unit. My wife was skeptical at first that this would be as good or better than our old unit with the idea of "unlimited" hot water and it didn't disappoint… We have a small house but both showers and washer can run all at the same time..actionmaytag
This water heater is perfect for my little house, endless hot water. Was somewhat of a challenge to DIY install but I made it happen. This unit drinks lots of power. Be sure you have room in your panel. Shark Bite fittings with copper plumbing is essential, much faster. Would definitely buy this again.rdricker81

I was originally skeptical this little water heater would be able to provide enough water for a bathroom and kitchen in my tiny house. It has kept up and worked fantastically even with family visiting for the holiday. I am seriously surprised by how well it works and I live in Pennsylvania where the water comes in quite cold.stpeteboyz8ys4
Put this in my work shop it's awesome finally got hot water and easy to installReid
It's a very straight forward high quality tankless water heater.Dave

Reviews:
We loved this unit when first installed. Now 1-1/2 years later, it has been replaced 2x. To be fair, B&D did replace but we had to install a total of 3 times at our cost. It has 3 internal breakers, which when tripped require the cover to be removed. When last replaced by B&D, they said no more warranty. We will not buy another. And yes, we had it hooked up to a water softener and filters.Patti
This heats the water great in the summer time, a little cooler in the winter time when the ground is cooler. Make sure you measure the distance from you furthest shower to you water hear location before purchasing, to ensure that your water heater will heat the water efficiently.Anonymous

I bought this tankless water heater several years ago to put in a trailer house at the lake. It worked so well that I bought a second one for a houseboat. I read many reviews on different brands and decided on the Stiebel Eltron after researching. I have been completely satisfied and am glad that I chose this particular brand. #sweepstakesBG

Nicely made unit. I had to put it a tough place to get at under the kitchen sink. So far it does what it is supposed to. I've installed two other manufactures units. One was an A.O.Smith. It took longer to put the power leads to the actual unit than necessary. It works fine but the design leaves much to be desired.Michael

Reviews:
pThis 9 kW unit was a warranty replacement for the first unit I installed. The issue with the first unit was that it showed a constant error code of "EF", which should mean the flow sensor isn't working. The circuit card logic was programmed incorrectly, however, which caused this error code to display even though there was not an issue with the flow sensor. Installation was easy. I tested the replacement unit to get some numbers on water temperature rise versus flow rate. It is February in southern Indiana and the water inlet temperature is 47 deg F. I was able to 108 deg F output water temperature at 2 GPM, and up to 131 deg F (unit maximum) at 1.5 GPM. The unit starts working with about 0.5 GPM flow./pS H.
pAirtherial Tankless water heaters have the design, look, feel and function of a well-engineered product. The matte black case and contrasting LCD display transforms a usually boring appliance into a nice "Wall Piece". However, after installation, I contacted the seller to resolve a fundamental hot/cold water issue, and found the representatives of Sain Store to be truly an example of excellence in customer service. The company reps (whom I contacted via phone and email) went far above and beyond my expectations to assist with resolving my issue and identifying the root cause. Ultimately, the problems experienced proved to be resultant of installer error, not an error with their product. I wholeheartedly recommend Airthereal Water heaters for their product quality & the manufacturer's post-sale customer service./pNWShopper007
I bought this water heater because my old tank heater went out. We had one of the big tank ones but it was like 25 years old. Anywho, installation was a tad difficult, but customer service is there for you! Now thats its all hooked up we have hot showers again!! Hot throughout the entire shower and my husband got in right after me and said the same thing!! Works good for the kitchen sink to! I live in Tn.Paula M.
