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.

  • Stiebel eltron tempra plus
Style: Tempra 24 Plus (24 kW) Pattern Name: Water Heater
The stiebel eltron tempra plus is an amazing heater. I bought it to heat my four bedroom house and it has not disappointed me. The water is hot in all bathrooms and kitchen just like I wanted. It is great value for money, efficient and was very easy to install. I would highly recommend.

  • Great product and worth the money.
Style: Tempra 24 Plus (24 kW) Pattern Name: Water Heater
First will say the only Con so far is when looking on here at the specs it actually calls for heavy wire the. What the manual said. I ordered my material also for the install when got it. Pros are easy to install and setup up, gets hot really fast and maintains temperature for as long as you need, and dropped are bill to the point in a year it has paid for itself plus you can write it off on taxes. I am a handyman/DIY with an electrical background so I did self install so would say hiring a professional is a must unless you have common knowledge of the trades needed. This would probably take longer to see savings than myself. ... show more

  • Efficient and Reliable Hot Water Solution
Style: Tempra 20 Plus (20 kW) Pattern Name: Water Heater
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

  • Amazing to say the least
Style: Tempra 20 Plus (20 kW) Pattern Name: Water Heater
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
