## Description

"The Stiebel Eltron Tempra 24 Plus Tankless Water Heater features exclusive Advanced Flow Control German patented technology invented by Stiebel Eltron to automatically maintain water temperature for constant comfort. It’ll reduce flow slightly if hot water demand exceeds capacity to ensure that hot showers will never be interrupted. Tempra 24 Plus will typically use 15-20% less energy compared to conventional electric tank water heaters. Although, it’s possible to save significantly more energy depending on personal home usage habits. The difference is that conventional tank water heaters continually store hot water, and as a result, lose 15%-20% of the total energy consumed to the environment around them. This is called standby heat loss. Tank water heaters that use gas or oil are even less efficient, because they also lose heat through their vents to the outdoors. Our tankless water heaters do not need venting, and will not store hot water, waiting for you to use it. They operate on-demand to provide continuous and endless hot water when you need it, and not waste energy when you don’t. CERTIFICATIONS INCLUDE - ANSI/UL Std. 499, CSA Std. C22.2 No. 88, ISO 9001, WQA tested & certified against NSF/ANSI 372 for lead free compliance.

## Questions & Answers

**Q: Electric panel is ~50 feet from where i want to install the tempra 29 trend. is this distance ok for #8 thhn wire?**
A: The recommended wire is 8/2 and there is not a limit to distance written in the install directions.
You need to check with your electrician. Make sure he is state license and insured. 
We have installed a Tempra 29 and our electrician ran three 8/2's approx. 30' with no question. But check with your electrician and local codes. God bless you and happy New Year.

**Q: Where is it made?**
A: The Tempra 29 is made in Holzminden, Germany, as of 8/16/2022.

**Q: How can i make tempra trend 24 work with my bosch shx33a05uc/22 dishwasher? the dishwasher will not advance to next cycle. water is not hot enough.**
A: This water heater activates at 0.5 GPM and will heat to your set temperature at the correct flow rate for that set temperature.  Please call our Technical Department at 1-800-582-8423  Ext 6 with more details so we can help you better.  (for example, does the dishwasher have its own heating element, distance between the 2 units, etc...)  Thank you.

**Q: Is there an installation kit available for this? i am installing in a remote location & plumbing parts are not available? water lines are pvc.**
A: There is no specific installation kit.   However, we suggest using flexible braided hose  connections that screw onto  the hot and cold water for the first 18" or so.  These connections are easy to remove to check a filter screen or if needed to work on the unit in general.  The connections are 3/4" NPT.  Please feel free to call our Technical Support Department at 1-800-582-8423  ext 6 with any questions.  Thank You.
