PRODUCT OVERVIEW

Model # Tempra 29

Internet # 204091795

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. Tempra Plus models incorporate an Advanced Flow Control that automatically reduces 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 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 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 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 percent efficient and typically result in savings of 15-20 percent in comparison with electric tank-type water heaters
  • Tempras use only the amount of energy necessary to heat the water needed
  • 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 is standard
  • See warranty for complete details of the 3-year residential and commercial warranty against defects in workmanship and materials under normal use

CUSTOMER REVIEWS

Rated 4 out of 5 by 4 reviewers.
Rated 1 out of 5 by Don't buy unless you already have 400amp service! This product requires 150amps! Most homes, if you are lucky, have a 200amp service. That would leave you with 50amps for all of your appliances and other electrical needs. Absurd! A regular energy efficient hot water heater requires 20 amps. I don't know how a product that requires 3 50 amp breakers would be energy efficient. So, if you want to pay to increase your electric service, pay an electrician to do all the work, and then spend almost 800.00 for this unit, go for it otherwise buy a Rheem. They have a lot more ratings and do not require an entire house of electricity to run it. February 3, 2014
Rated 5 out of 5 by Good quality, good performance I had installed a tankless hot water heater from another manufacturer, which failed after 8 years, and decided to get what seemed like a somewhat more expensive, but better quality and higher capacity system. So far, it looks like I made the right choice, because the output has been uniformly hot despite the relatively cold water coming in (this is in the Adirondacks, so the real test will come in winter), and the temperature is easy to adjust. Since I was replacing another tankless heater, installation was relatively simple. The wiring was in place (three sets of #8 gauge), but I had to upgrade the three circuit breakers from 45 amps to 50 amps. Adjust the mounting screws on the wall, reconnect the water connections, connect the wires, and I was done. July 24, 2013
Rated 5 out of 5 Easy to install. Instructions are easy to follow Easy to install. Instructions are easy to follow. I would recommend to others. Very small for the amount of water it can eat. September 17, 2013
Rated 5 out of 5 by LOVE IT!!! We had a bosh unit prior to this one, which was smaller. With this unit you can flush the toilet, or wash your hands while someone is in the shower without an issue. Our plumber recommended this unit - said this company has a great product and great customer service...he actually had the local reps number in his phone! We have saves some serious cash over the years with our other unit, so if you are debating on upgrading definitely do it! July 16, 2013
