The Tempra 29B was the predecessor of the Tempra 29 Trend. It offers all the same features of the Tempra 29 Trend except for the digital display. It comes in a grey case instead of the white associated with the Tempra Trend series.

  • 28.8 kW's of Power
  • Thermostatically Controlled
  • Requires 200 Amp Service
The Stiebel Eltron Tempra 29B electric tankless water heater is a powerful 28.8KW heater designed for whole house and commercial applications in cold climates where the incoming water temperature can drop below 40F. It is also a popular choice for homes in warmer climates with high flow demands where multiple simultaneous hot water demands are required (up to 6 gallons per minute), or where fast fill rates for large Roman or bath tubs are desired.

Like all Tempra B series tankless water heaters, the Tempra 29B features true microprocessor-controlled temperature regulation and a 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 29B 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 result is the most precise temperature control of any tankless water heater on the market today!

Do You Have Hard Water?
If your water hardness trends above 7 grains per gallon (GPG) or 120 mg/l (ppm), you should consider hard water treatment prior to your tankless water heater. If your hardness exceeds 12 GPG or 200 mg/l (ppm), hard water treatment is strongly recommended.

Hard water treatment helps maintain performance and efficiency, ensures optimal water flow and pressure, and protects your heater from pre-mature failure due to mineral build-up inside the heating module and other components.

* Breaker size and wire gauge must meet all applicable local, state, provincial, and national electrical codes for your area - these are only guidelines that will apply to most installations. Some codes require use of electrical sub-panel for installation, especially when heater is not mounted within line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load. Please consult your electrician for more details.

Please note: A minimum 200 AMP household electrical service is highly recommended and will likely be required to install this model. If you are unsure of your electrical capacity in your home, please consult your electrician or contact us for assistance before ordering.

Steibel 15 4 Stars
Installed the unit according to the directions and it did not work at first. I think because the water pressure needed time to reach normal in the unit. It now works fine to heat our master bath fixtures - Stephen K

Love it, works great & company very helpful when ordering. - Janice

Great heater5 Stars
When my home was built 25 years ago, this was the hot water heater. You might be thinking that a hot water heater should justifiably last an easy 25 years. I have well water, and 1 filter before the heater. This statement says more. I absolutely had to get the same one. It is a little taller so a tiny bit of plumbing and tada, easy to install. I am pretty old fashioned so the extra options are not important to me, but all I did was set it to 110 degrees with the dial, done. In 25 years I will get another if it is needed. I had a GE tank break after 2 years and the insurance stuck it to me. Personally I am so very sick of garbage on the market. This unit in my home has a proven track record and I am all about proof. - Steve A
