Like all Tempra Plus Series tankless water heaters, the Tempra 29 Plus features true microprocessor-controlled temperature regulation as well as a convenient digital temperature display and dial selector which allows you to set the desired output water temperature at any level between 86 and 140F (30 and 60C). It is one of the only tankless water heaters on the market that features a true thermostatic temperature control and full power-modulation based on both the incoming water temperature and the water flow rate. The Tempra 29 Plus will automatically adjust its power output to accommodate changes in the incoming water temperature and flow rate so it can precisely maintain the desired output temperature.
The Tempra 29 Plus also features Stiebel Eltron's exclusive dynamic Advanced Flow Control technology. This technology automatically adjusts the flow of water when the unit's sensors detect that the flow demand is exceeding the heater's capacity. This feature is particularly useful in cold climates and other applications where the electrical service size does not permit the installation of a larger model and it may be desirable to handle occasional high flow demands. It is also desirable where high output temperatures are required for temperature critical applications (commercial dishwashers, etc.) and where flow rates are not always predictable.
Simply stated, the Stiebel Eltron Tempra Plus Series electric tankless water heaters feature the most precise temperature control of any tankless water heater on the market today!

Stiebel Eltron Tempra 29 Plus (White) Reviews
Excellent unit working with Solar Thermal Hot Water
Purchase and installed my unit in April 2015; wanted to wait a full year before making a review. In a small utility/laundry room I replaced my 40gal electric hot water storage tank with a 60gal storage tank for storing solar thermally heated water. I did not have room for 2 tanks so I decided to go tank less water heating. I reviewed options when professional advise given to me was to go natural gas, but decided after careful study to go with the Tempra 29 PLUS. The savings I am making by preheating my domestic water with Solar Thermal collector panels is showing up as 8kwH/day and the Tempra 29PLUS kicks in when there has been no sun for several days. I have the Tempra set high at 128 and my my solar thermal storage tank set at max temp of 175degF; there are no issues with water at 175degC passing through Tempra...it just does not power on. When there is no sun for several days the Tempra can handle both showers in the home being used at the same time with no issues, and my hydro bill does not kick upwards. A little more expensive to install than a condensing natural gas tankless, but if you have space challenges and cannot get flues out through a wall then this E-tankless is a great way to go, especially with Solar Thermal Hot water preheating. - David F
Very reliable performance
We installed our Tempra 29 Plus in 2010 and the unit has worked flawlessly since we've owned it. The odd time, we'll adjust the temperature up or down a few degrees, but it has been hanging on the storage room wall untouched for the most part. The heating is very even in the shower and for washing dishes. No temperature fluctuations at all. Other than some fixtures that are a long way away from the heater, the water is heated and arrives as the faucets very quickly. For dishwasher loads (and if there's a hot load of laundry) we always run the closest sink until we get hot water and then turn on the wash cycle. In terms of operating costs, the household hydro bill is slightly higher, but very reasonable. Our gas bill has probably decreased more than enough to offset the increase in hydro. This unit has been very efficient for our family and still operates as well now as it did the day we put it into use. Would definitely recommend this efficient heater to other people here in B.C. or other parts of the country. - Josh
Excellent Water Heater
Excellent water heater. The plumber said it was easy to install. Super tech support, documentation was first rate. But the most important there is plenty of hot water, and no huge tank in the garage any longer. - Pedro
Replacing 10 year old tankless
Saved us money the first month with more efficient operation than our old tankless unit, newer tech very happy with this - B Bailey
Tankless electric water heater.
Works as expected. - Andrew
Great Product - Could be better though
I am very happy with our conversion to tankless. This product is outstanding; well-built and works as advertised. However, I wish the flow detection switch was either more sensitive, or user adjustable. As is, you have to turn the hot water on to a pretty high rate of flow for the heater to kick on. This is fine for most uses, but for things like shaving, where I would normally turn the water on at a slow rate, the flow is not detected by the heater. I turn the water up to solve this, but can't help thinking about the amount of water that is being wasted. One of the reasons I converted is wasted energy on a tank, and now it seems the waste was just shifted to water use. - Ken S
Exceeded my expectations
I installed the water heater in February in Saint Paul, MN. My water temperature coming from the street is probably in the forties Fahrenheit. It is cold enough to make your hands numb. I was a little worried that it wouldn't have enough capacity for my family of 6 with 4 bathrooms. It is working just fine. After some experimenting, we ended up setting the temperature at 115. We can easily take 2 showers at the same time. If the washer and dishwasher are going at the same time, the 3rd floor shower will decrease flow to a trickle without changing temperature. I am very happy so far. I installed it myself. I have a 200 amp service so I had room for the necessary 3 separate 30 amp 220 volt circuits. Some electrical items in the house will exhibit a little fluctuation when the heater kicks in, although it is pretty subtle. Hopefully it continues this performance over the long haul. If it lasts 15 years with this performance, I will be very happy. - John S
The heater is extremely easy to install. It is is even easier to operate. It worked perfectly the moment it was commissioned and performs the same on every use. The water is hot more quickly and it is great to have an endless supply of hot water. E-Tankless was a great resource, responsive, and shipped the heater quickly. They are a fantastic company with great quality products and service. - David Tishim
We have had our tankless heater for over 6 weeks and it has not failed to produce all the hot water (128 degrees). Several showers at once and a washing machine. Very impressed. Have noticed a slight increase in electric bill but, it's worth it to not have to worry about running out of water! - J. Norton
- Rusty W.
Love my new water heater, light years ahead of my old Sets system. User instructions could be a bit better as could install instructions. Should mention a flushing system should be installed at the same time to get rid of calcium.. - G. Martin
So Far so good
Im in CA and I replaced it in the summer, so far it was easy to install, and easy to work with, I will know if it is the perfect unit when winter comes and the inbound water is colder but so far so good. - Burke Race
So far it is excellent - Oscar Henry
Perfect so far
I purchased a Tempra Plus water heater and had it installed by Professional plumber/electrician and it works perfect so far. - Mircea Micula
Love it. Very good quality - A Creation By Mario

Excellent product and service
This is a wonderful product, engineered to German precision specifications. I highly recommend it, and the price was better than anything I could find anywhere else. The service I received was superb and I could not recommend this company any more strongly. Highly professional, courteous, friendly, and full of relevant information. I was impressed from the beginning of the transaction to the very end. I wouldn’t hesitate to make a purchase. Great service and products. - Daniel
The unit is performing wonderfully—but just as important was the expert advice and support that I received from Grant Robertson at E-Tankless - Janice B
Great tankless water heater
Excellent product and excellent support team, thank you! - Gary R Lamarand
A Homemaker’s Dream! (Big Family)
We are a family of 7 and this has been a game changer for us. There are several improvements I’ve noticed since switching from a traditional hot water tank to this system- 1) it’s foot print is dramatically smaller. In fact, it’s not much of an actual foot print at all since it hangs up on the wall out of the way. 2) I hand wash all of our dishes (3 meals a day as I stay home with our kids) so we have an industrial kitchen sink. Before we got this water heater, I used to have to use one tank of water to fill the sink and then wait a bit to come back and finish washing/rinsing. Not anymore! Now I can do a sink FULL of dishes in one shebang. 3) Before, I could either start a load of clothes OR wash dishes… this is no longer a problem either! I can do both at the same time now! With so many kids (5), anything that makes my life easier (more productive, more simple, etc.) is a big win in my book! And this system is a BIG WIN in my book!!! I’ve already recommended it to several other big families we attend church with and really anyone else that comes over to see the progress we’ve made on our new laundry room (where it’s located in our home). I love it!!! In terms of installation, my husband did it himself. He works construction but plumbing is not his forte but it was simple enough for him to install. But a simple service call with a plumber would suffice, for sure. Ordering, shopping, customer service, etc. with this company have all been wonderful too. Everything has just been great! - Love it!
Other Tempra Plus Series Reviews
Great improvement over a hot water heater. Nice to have all the hot water I want and save on bills. More space in garage. - Linda
2 Years Running Strong at the Farm
Don't hesitate to consider going tankless or if your wondering if gas is cheaper etc. I purchased this unit 2 years ago for my farm a to replace a 26 year old water tank. The price per month for electricity is lower and the water hot water is clean because it doesn't sit in the water tank! I installed this with 2 double pole 60 amp breakers and 6/2 wire.. Simple. - Anonymous
SO much better
Purchased this unit to replace another tankless water heater and the Tempra 24 Plus is SO much better. Installation was easy and the flow control on this unit makes all the difference. You can't go wrong with this unit as we have had great success for the 1.5 years we have been using it. - David
I use these tankless water heaters to replace old or failing water heaters in my apartments. I have ordered 7 so far (installed 5) and everyone loves them, especially me as it cuts down on my maintenance. E-tankless has been great to work with as well. - Eugene P.
It works as advertised. We are very pleased. - Tom M.
Waters Hot and Lots of It
I turn on the water and I get hot water. There's little else to say. Completely satisfied! - Richard L
Tankless hotwater heater
Outstanding and allows us to use two or more hot water outlets at the same time. Two showers and a dishwasher all at the same time and everyone gets hot water - Ed G
Does what it was intended
Provides unlimited hot water for the house. It runs both showers for 30 plus min with no problem. - Jason H
Works great and will even fill my bathtub. My house is 1620 SQFT and I live in Waskom, TX 75692. I have my temperature setting @ 111F. - Josh
Love it - Ron T

Stiebel Eltron Tempra 24 PLUS Tankless Water Heater
I am very pleased with the performance of my Stiebel Eltron Tempra 24 Plus Tankless Water Heater. It works well is efficient and the staff at E-Tankless were helpful and knowledgeable. I am super happy with my purchase and company service. - Debbie Walsh
The Tempra 29 Plus is Fantastic!
After our third water tank flooding the playroom, we knew it was time to do something else. We are so pleased with our decision to go to an electric tankless water heater and definitely with Stiebel Eltron. We chose the refurbished to save a few bucks and has worked out fine. Had they not told me, I would have not known. I did a lot of research and decided it was not worth the cost and relocation to gas. So glad! I was worried about the size since we could not go up to the 36 Plus. No fears. We are never without hot water! The unit is very efficient and cheaper to run than the tank model. Highly recommended! And a special shout out to E-Tankless...I called a few times and they were MOST helpful and informative! - Kathy H.
This thing is amazing! We live in Indiana and it works perfectly. We set the water temperature to 125 and the water was MUCH hotter than our Tank-water heater could ever do, so we moved the temp down to 115 on the dial which literally takes seconds. Non-stop hot water. I have been recommending this to everyone! Takes up almost NO space. You need TWO 6/2 cables and TWO 50 AMP double-pole circuit breakers for the full 100 AMPs of power it may potentially pull, but we have never gotten anywhere close to that. We have saved 10% on our first energy bill. The system literally pays for itself. Spend the money, get the system. Its worth it. I would recommend that you have a water softener if you are getting this water heater. But according to the website, it is not needed. The only difficulty in installation would be that most homes do not have two double-pole 50 amp circuit breakers. These are by no means difficult to install but you should either ask an electrician friend for help, or google it. Works exactly like advertised. We got the Tempera 24 Plus. - Dane
Bought a Recon Tempra 36 plus Instant Hot water heater for the brewery. Works very well, puts out 140 deg water at 3.0 gal/min. The plus model automatically adjusts the flow to maintain the 140 deg temp. Will allow me to mash direct into the kettle with the water filtered before going thru the heater. Would highly recommend this heater to anyone looking for a whole house instant heater. You just have to make sure you have the AMP capacity to supply the 36 KW heaters. - Dakota Brewery LLC
super easy to install once the electrician finished wiring, the water is hot and for our small home with 2 adults, we have never ran out of hot water. The company was super helpful and the shipping was fast. - Ron
A Really GREAT Product!
I had 3 or 4 other tankless water heaters before I got my first Stiebel Eltron Tempra. All of them failed after a very short while. Then I got my first Stiebel! This thing was amazing! It worked like a charm ... every time for months. I had to send it back for repairs because I didn't realize how hard my water really was (it clogged) and got another Tempra 15 to use while the first one was refurbished. I LOVE the digital temp. control. I just set the temp. at ideal for my shower and never turn the cold water on. One hint: every few months I circulate food grade vitamin C thru the water heater for about an hour using an aquarium pump. That keeps it from getting clogged with minerals and you don't have to use caustic chemicals. This is my third Stiebel Eltron Tempra Plus (the other 2 were lost in a house fire) and I couldn't recommend it more highly. - David C.
WE are most pleased with our purchase, having been an upgrade from an old 50 gallon tank water heater. We've had readily available limitless hot water since we installed the Tempra 20 Plus system one week ago. - Kyle L
I screwed up, they helped
This is a hard review for me to do, as I screwed up. I had two 30 amp breakers and they had the only good looking tankless for a 2 x 30 amp. I ordered it, that was fine, I got the unit and it was in great shape. The install was very easy. My problem was that my 30 amp breaker was only one wire (per breaker) not two as need for the unit too work. Yes, this was in the product literature. So, I screwed up I did not have the right wiring for the unit to work properly. I was able to return the unit. The return went smoothly and well. So if I have any needs for a tankless hot water heater in the future with proper electrical lines I will not hesitate to order from them again. - Mike Berman
Tankless water heater
Best service I've ever had Working great and we love it - Carol Bunyard
excellent water heater
This water heater is extremely good quality and pumps out tremendously HOT water-actually too hot, I had to turn it down so as not to burn us!! - Marshall Swanberg
Tankless Water Heater
We like the water heater. We noticed that sometimes when running hot water at faucit slowly the water heater appears not to detect the flow so it cold water is delivered at the faucit. Otherwise, the product is great - Roger Buchholtz
This is very useful for customers with kitchen that does not have access to gas water heater-which entails coring a hole on the roof of the building. With this, you just install and enjoy. - Seema
I have not installed the unit yet, but the service I received in ordering was excellent! She answered my questions and made the process easy. Thank you! - Erin
Great product and price.
Received this quickly and had it installed and wired by the electrician. Four weeks later the plumber showed up and it works perfectly. Great having unlimited hot water when needed but no wasted power when it's not in use. - Bill Murchie
Stiebel Eltron Tempra 24 Plus Tankless Water Heater
I have not yet hooked up this water heater but I bought it because I own 2 others, same brand different generation. And they both work great, I have nothing but great things to say about them. I expect the same from this one! Thanks for a great product. - Esther Vinzant
Definitely should get if you have a large family
I bought my first Stiebel Eltron Tempra 36 Plus 14 years ago. it was the first generation. I am in the throws of full house renovations and so I bought the new 3rd generation. In 14 years, never once have I had to service the unit. Reliable 100% of the time. We are a family of 8, and the shower is used multiple times a day, every day and our washing machine operates 365/yr. Add to that a dishwasher, and other daily water uses that demand hot water. This is definitely an excellent investment, just by never having to worry about running out of hot water. Add to that, it takes virtually no space, compared to the gas heating/water tank system that was here when we bought the house. The only issue...and it's not a biggie, is that it does require a lot of amps to install, 3 x 60 amps. That said, I upgraded my electric panel to accommodate the new unit along with the other upgrades I did in my renos, however, it was not really an issue for the previous 14 years with my 1st gen unit. This unit pays for itself in the first year (and its really not expensive to start). If you have a large family and need a lot of reliable hot water, and not wanting to worry about showers going cold after 15 minutes of use and waiting an hour for the traditional method of your water tank to fill up for the next shower....then by all means, do yourself a favour and buy a unit. - Jack Daniels

This is the second house that I have built using Stiebel Eltron Tempra 36 Plus tankless on demand water heater. It is an excellent product that is both extremely efficient and has no green house emissions. - Pat
