Description
–
Powerful output, compact design, remarkable energy-saving features. Our whole house electric tankless water heaters perform with the highest standards for comfort and reliability. Tempra Plus models feature Advanced Flow Control, patented in Germany and exclusive to Stiebel Eltron tankless heaters. If hot water demand exceeds working capacity, Advanced Flow Control automatically maintains consistent temperatures by slightly reducing flow. Intelligent self-modulating technology continually ensures the least amount of energy is used to heat the water. A Tempra 29 Plus provides hot water at a consistent temperature for up to 3 bathrooms in warm climates, or 1.5-3 bathroom in cool climates. See sizing to determine which model is best for you. Stiebel Eltron invented tankless electric water heating technology more than 90 years ago, and is still the industry pioneer and world leader. Our engineering and manufacturing tradition of excellence means you can depend on the performance and reliability of our products.
- Smart microprocessor technology unique to Tempra water heaters delivers steady water temperature even when flow rate vary as taps are adjusted
- This Tempra Plus model has German patented Advanced Flow Control that automatically reduces output flow to maintain temperature if demand temporarily exceeds capacity.
- Self-modulating technology saves energy by adjusting electrical usage
- Tempra 29 Plus has a maximum power draw of 120 Amps via 3 separate dedicated 40 Amp DP breakers and 3 separate runs of 8-gauge copper wiring, and the electrical service to the residence should be checked to make sure it is sufficient
- Tempra tankless electric water heaters must be correctly sized and you should consult the sizing guide to determine the correct model for you
- Requires 240 Volt or 208 Volt electric service, and has a maximum output of 28,800 Watts at 240 Volts or 21,600 Watts at 208 Volts
- Supplies endless hot water at a constant and steady temperature from 68 to 140°F (20-60°C) that can be set on the front panel digital display
- Flow rate you achieve from this or any tankless water heater depends on how powerful the unit is and the temperature difference between the incoming cold water and the hot water being delivered
- 99% efficient and typically result in savings of 15-20% in comparison with electric tank water heaters
- Must be installed vertically, water fittings pointing down, with detachable connections such as braided flex connectors to allow periodic filter cleaning and flushing for scale, and an anti-scale filter is recommended if hard water is present
- Professional installation recommended

go tankless
Family of 5 in new jersey and no problems with hot water with this unit. If the dishwasher is goin and someone's already takin a shower and it's winter so the incoming wanter temp is already cold u might notice that the unit cant keep up, but i consider that a small adjustment to make to save money on your electric bill. Speaking of, i havent gotten my bill yet so im not sure exactly how much i am saving, but another perk is the room ive gained in my laundry room after removing a 50 gallon tank and putting this vcr-sized unit on the wall. I used shark bite plumbing hardware to make the connections and hired an electrician to connect the juice. He was already here cuz i had to upgrade my electric from 150 amp to 200 amp service. If youre water irs heated by electric, i highly recommend going tankless. Not one single complaint yet. Also, if u do, put ball valves on the line before the unit and after the unit so you can completely isolate it from any water flow. This way you can service it. I read one review where a lady unhooked the intake line to the unit to have it serviced and she got water all over her basement... So, ummm, dont be that lady and install ball valves so you can stop the water flow before disconnecting the lines lol. Get it. Go tankless. Go green.

Good but with quirks and reservations
I have been using this for almost 5 years. Here are my thoughts.
It pulls a lot of power, I mean a lot. Takes three 40 AMP circuits, so when it goes on, my LED lights flicker, my microwave works very slowly, the Voltage of the house goes down by about 7%. I have a 200A service but I think you need to have a 300A service for this to work flawlessly.
Needless to say, so far, knock on wood, I have not had any electronics failed due to this. My electric car sometimes won't charge because of the fluctuation in power.
Recently the flow sensor failed, so I have to replace it and it is out of warranty. Called Stiebel Eltron and they overnight the part to me (I have to pay).
The pros is endless hot supply, but that's pretty much it.
I am mulling over switching back to tank.

This is a great electric tankless water heater. Unfortunately, it is the second one I purchased, because the first one got fried by a lightening strike on my house. I got the exact same one.

Energy efficient, only real way to fill a hot tub nlss you have an 80 gal water heater or an instant water heating system ( which defeats any energy savings)

I did buy this product again after 11 years.
Both are still working great. This is my second one. I bought one to put in another house we just bought. Works great and the electric bill is not high at all.

So far so GOOD! easy to wire and operate!
I bought two of these! one for my in floor radiant heat system and on for my house hot water.
So far the floor heat is running great. Although this isnt "designed" for radiant heat ive seen may people use tankless setups vs boilers. I do plan to make sure to flush the sustem annually and clean for hard water build up but its compact size was much better for me than the large boiler i had planned to use.
The unit wired up very well, I ran 3 runs of 8/2 wire from my panel (40AMP 2pole breakers) to the unit and connected the water lines. filled the system with water and turned the breakers on. It works great so far after a few days of use. Time will tell but the unit is build very well.

Wish I would have done this years ago
I was concerned with two bathrooms and a wife that loves hot water, and well, the Tempra 29+ does the job! I live in Western Maryland and have a colder climate, but three weeks in with 50F water (it's December), I can run two showers with capacity to spare—this unit is great! I thought about the 24+ but am glad I went for the 29+ given the temperature of our incoming water and the need to run two showers. I installed it myself and the instructions were clear and the unit is built like a tank. My wife is happy and so am I!

I switched from an EcoSmart 27 to this unit. This unit is much better quality. This unit delivers a very consistent temperature and I can already see the energy savings.

Q: Can this be used to wash dogs continually all day
Asked by Hydrant 10 years ago
Add your answer
-
I see no reason why not. This unit heats as long as there is a demand for hot water. If the demand is very low, it might not cut on. There is a safety feature that prevents it from overheating. It also has a 140F maximum temp output that limits the total energy it can put out. We have had no problems with ours whatsoever. This is a great product.

Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffYou may be able to get by with a smaller unit, depending on where you live (in a warmer climate, water does not have to be heated up as much). The key factor with tankless water heaters is to make sure they can meet your GPM requirements.

Q: do these tanks clog up due to hard water
Asked by 16 years ago
Add your answer
Verified Reply- PexSupply StaffThese tanks can clog due to hard water in the system. We would recommend that you add a Wye Strainer to your system to prevent this from happening. You can consider SKU: 0220071 which is a Wye Strainer.
