    • Efficient and Reliable Hot Water Solution
Size: 20 (kW) Style: Tempra Plus
Review Image by JWhatJwho
Review Image by JWhatJwho
The media could not be loaded. 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. ... show more

    • 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. ... show more

Fantastic heater. I oversized a bit to make sure I'm able to heat well water during mid TX freeze (upper teens). 2 bed, one bath and this unit doesn't break a sweat. Has been 100 percent reliable and temp is stable. Customer service is fantastic (install issue on my end). You get what you pay for, and this brand is no exception. Highly recommend ... show more

    • Generally happy about it...
Size: 20 (kW) Style: Tempra Plus
Replaced our monstrosity of a tank with this tankless. Decided on electric because I did not want to have to install additional venting. 80psi from outside so I also had to put a flow restrictor to ensure proper heating of the hot water line. So far so good. Only wish is Stiebel could have offered more than 7 years warranty. btw, filling a bathtub hot is still challenging but since we are water conscious we rarely do full bathtub baths... ... show more

    • Amazing to say the least
Size: 20 (kW) Style: Tempra Plus
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. Excellent product! ... show more

    • Great whole house heater for a small space install.
Size: 20 (kW) Style: Tempra Plus
Review Image by Joseph G
I have a 1100 sq foot one and half bath bungalow style home located in the Atlanta area. Due the age of the home, the old water heater was installed under the counter as a low boy style water heater. The Stiebel went in without issue, even though I did have to run two new 40 amp circuits. I think most home owners upgrading to a tankless will have to upgrade their electrical, so they need to plan for this. Overall, this tankless works great and saves space. The water gets hot, and I mean hot, and having unlimited hot water is great as my old low boy style tanked heater would run out quite quickly. ... show more

    • Great instant water heater
Size: 20 (kW) Style: Tempra Plus
I bought this water heater for a 2 bath house. We already had the 2 x 40 amp setup so I didn’t want to increase the amp load although I wasn’t sure it would work smoothly. It does, It works perfectly with no interruptions in temperature or flow.

    • Great heater for our restaurant's commercial dishwasher.
Size: 20 (kW) Style: Tempra Plus
Installed this unit as a booster for our commercial dishwasher in a restaurant. This thing is great! We put a high volume of water through this every day. Our two electric hot water heaters just couldn't keep up. We installed this inline to our dishwasher intake as a booster and we have zero issues now. Very easy installation. Highly recommended. ... show more
