PRODUCT OVERVIEW

Model # Tempra 29 Plus

Internet # 203210875

Stiebel Eltron developed tankless electric water heating technology 90 years ago and continues as 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. Tempra models are whole house tankless electric water heaters, never wasting energy storing hot water, but delivering it as you need it, as long as you need it. The compact design needs no venting, allowing for installation close to draw off points, making the wait for hot water as short as possible and maximizing energy savings. Tempra tankless water heaters are sized based on the number of bathrooms and your climate. Refer to the Tempra Sizing Guide under 'More Views' to determine which model you need. Call Stiebel Eltron at 800.582.8423 if you have high flow showers, or any sizing questions. Tempra models supply water at a constant temperature from 86 to 140 degrees F that is settable on the front panel. We recommend setting the actual highest temperature you use, typically 107 degrees for a shower. This is a Tempra Plus model with an Advanced Flow Control to automatically reduce flow rates to deliver water at the set point even if demand exceeds capacity. Regular Tempra models do not have this feature and should be considered if this is not of concern. Tempra 29 Plus models provide hot water for 2 or 3 bathrooms in cool climates or 3 bathrooms in warm climates, and have a power draw of 120 amps.

  • Professional installation recommended
  • Tempra 29 Plus models require 208 or 240 volt electric service, with a maximum draw of 21,600 watts at 208 volts or 28,800 watts at 240 volts
  • Tempra 29 Plus has a power draw of 120 amps via 3 separate 50 amp breakers with 8 gauge copper wiring
  • Tempra tankless electric water heaters are 99% efficient and typically result in savings of 15-20% in comparison with electric tank-type water heaters
  • Tempras use only the amount of energy necessary to heat the water needed
  • The sleek European design is considerably smaller than a tank, saving space and allowing flexibility to determine the best location for installation
  • Tempra units must be installed vertically with the water fittings pointing down
  • Tempra tankless water heaters work better than tank-type water heaters in hard water environments because they can be set to lower temperatures, which minimizes scale formation
  • Water connections for Tempra water heaters must be detachable (such as braided steel flex connectors) to allow periodic filter cleaning, including flushing for scale if hard water is present
  • Tempra tankless water heaters are ETL Listed for compliance with CSA and UL safety standards in the US and Canada
  • Tempra tankless electric water heaters are exempt from seismic code
  • Overheat safety protection and thermal protection reset are standard
  • See warranty for complete details of the 3-year residential and commercial warranty against defects in workmanship and materials under normal use
  • This is a Tempra Plus model that incorporates an Advanced Flow Control to automatically reduce flow to deliver water at the set point if demand exceeds capacity

CUSTOMER REVIEWS

Rated 4.3 out of 5 by 21 reviewers.
Rated 5 out of 5 by Excellent product! Works well for whole house! Background: We originally had a 50 gallon propane hot water heater, coupled with a hydronic air handler for home heating. The combined usage made for very expensive propane bills, so we decided to upgrade to a tankless system. After reading reviews and doing some homework, we decided this was the best unit for us. Homework: We live in the Pacific Northwest and our inlet temperature is around 40 degrees, so we were concerned that the resultant temperature rise would limit flow beyond usage but this system delivers! When deciding if this system is the right one for you, take into account that you will need room for 3 double throw 50 amp breakers(6 slots) and atleast a 200 amp electrical service to your home. Wiring requires 8/3 wire (w/o ground). If you are atleast somewhat competent with electrical work, you can install this yourself no problem. Took me about a day to do it all myself. The system keeps and maintains 123 degrees comfortably for dishwasher, hydronic furnace, laundry, and shower at same time (although we have low flow energy efficient items). The cons to this system is the expense of copper wire and items required to install. Even if you do it yourself your looking at a couple hundred dollars for just the hardware but in my opinion it will make it up in a few years from not having to heat the water all day and night while its not being used. The next con is that this system requires a larger pull on demand to activate the heating element. It's not an issue really but if you like to just turn hot water to a trickle, this will not work. The last possible con would be its a 28kw system so it's a huge electrical pull when used. Just make sure your home has enough room left over to use this system before you buy it. Just for a reference, I calculated that it will cost us $3.28 for every hour of run time of the water heater. Over all it's a great unit, works as advertised, heat is constant and nice and even regardless of what's being turned on or off. The benefit of the "plus" system vice the other is that this system will automatically throttle pressure to ensure temperature maintains consistency. Good value . I recommend! March 5, 2013
Rated 4 out of 5 by like the size and easy of installation. Really nice to have hot water after my wife and kids all take baths and showers!! May 27, 2014
Rated 4 out of 5 by I recommend this product over all other instant w/heaters I have had the tempra 29 installed in my home for over 5 years now. All though i am not convinced that it is as efficient as they claim. i have over seen several alternative brands in homes that i have constructed from gas to electric installations and chose this particular brand and size for my own personal home and have been overall pleased with my decision. Your flows are limited when using these type heaters which means slower fill times. do the math. 30 minutes to fill a bath tub @ 14.4KW = 5,256Kw a year for each person in you home that baths daily. Thats more than a 50 gal tank heater uses each year. So my suggestion is to not install to save money but for convenience only. Further more by code you will need a 400amp service to install this beast in new construction. March 11, 2013
Rated 5 out of 5 by Unlimited hot water I had this unit installed and had hot water in minutes. The electrician charged around $600 to run wiring. I did the plumbing and instal myself. It was very easy to put on the wall. I used shark bite fitting. I noticed a savings of about $100 on my last electric bill but I'll try to update this review because it went from very cold to average temp outside so I think the heat not being on affected my bill as well. I have high flow shower heads and noticed the pressure was a little less but not that bad. If you run several appliances at one time then the pressure goes down even more. I just don't do wash with hot water while I'm showering and that seems to work fine. Overall I'm very happy. I'm saving money and have unlimited hot water. It gets extremely hot so be careful. Hope this helps. Thanks May 5, 2013
Rated 5 out of 5 by Hydronic heating I noticed in the first review of this product the person mention he was using his unit for hydronic heating as well. Be aware that this is not warranted by the manufacture and will void any and all warranties. Great product but it cannot be used in combination with hydronic heating and maintain your warranty October 3, 2014
