Review: Efficient and Reliable Hot Water Solution - I recently had the Stibel Electron Tempera 20 electric tankless water heater professionally installed in my two-story home, and I couldn't be happier with the results. The installation took about four hours, including the addition of a whole-home water filtration system on the main line. The unit's performance has exceeded my expectations in terms of convenience and efficiency. First and foremost, the unit is impressively quiet, and its space-saving design is a game-changer. It doesn't take up much room, and the minimal noise is a bonus, especially if it's installed near living spaces. But what truly sets this tankless water heater apart is its ability to provide a continuous flow of hot water. I've tested it by running two showers simultaneously for an extended period, and there was no interruption in the supply of hot water. The heater only uses the hot water necessary, which is not only eco-friendly but also cost-effective. The temperature control is precise, ensuring that you get the hot water you desire without any fuss. I appreciate the quality of this unit, and even the licensed plumber who installed it mentioned that it's one of the top brands in the market. This gave me confidence in my purchase decision. I had concerns about whether it would deliver hot water everywhere in my house, but those worries were unfounded. My two-bedroom, two-story home now enjoys consistent hot water supply throughout. Of course, like any appliance, it's important to manage usage efficiently. Running multiple showers, a dishwasher, and a washing machine simultaneously might be a stretch for any water heater. However, with a bit of scheduling and planning, I've had no issues. I wash in the morning, run the dishwasher before bedtime, and take showers at various times throughout the day, ensuring they don't overlap. In conclusion, investing in the Stibel Electron Tempera 20 electric tankless water heater has been a wise decision for my household. It's efficient, reliable, and space-saving, making it a top-notch choice for anyone in need of a hot water solution. I also highly recommend having it professionally installed for peace of mind. It's a purchase that I'm truly satisfied with. Review: Great, takes up little space, very hot - Purchases 2022 Works well and gets smoking hot I only have it hooked up to 3 sinks, a washer and a dishwasher but I’ve never had an issue with hot water, I also haven’t ran all those at once. I give it 5 stars cause it does the job. You will have to run 8 gauge wire to it if you get the Tempra 20 make sure to hook up the proper breakers (ask grok or gpt). It does takes a lot of power when in use the good thing is it’s not in use unless you have the hot water running. Tankless take up very little room. I did use shark bites lol. ## Features - CONTINUOUS FLOW – Advanced Flow Control patented technology invented by Stiebel Eltron, automatically maintains water temperature for constant comfort.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Efficient and Reliable Hot Water Solution *by J***O on September 27, 2023* I recently had the Stibel Electron Tempera 20 electric tankless water heater professionally installed in my two-story home, and I couldn't be happier with the results.

I did use shark bites lol. ### ⭐⭐⭐⭐⭐ Amazing to say the least *by A***R on February 14, 2024* This is an absolutely amazing water heater. I replaced my propane tanked water heater with this. My dad and I installed it ourselves in about 3 hours including running new electric to the water heater closet, (he is a construction contractor by trade and knows how to do these things). But if you already have electricity to the installation site, (220. NOT 110), this is pretty straight forward and can easily be a DIY install. On to performance. I was skeptical at first, having been told by a few plumbers that on-demand technology wasn't up to par. But after having numerous serious incidents with multiple, professionally installed, tanked heaters, and after some research, I decided to give this one a shot. I have to say that not only am I impressed, but was also shocked and highly satisfied with this machines performance. It produces hot water, on demand, limited only by your water supply. I have mine set at 116 degrees, (extremely easy to read/adjust the display/temperature), and we take showers back to back to back to back here now, and it doesn't even break a sweat.
