"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.

Title: Works great! Love it
Review: I like how compact it is. It takes up a fraction of the space of my previous water heater. Very high quality and almost silent. Heats water very fast and it is super easy to use the settings. I drilled a hole through the back of the unit to run my electrical wire right into the box from inside the wall. Installation of the box itself was easy. The hard part was running 2 8 gauge wires through the wall and attic and back down into my electrical box. After that was done, I plumbed up the unit with corrugated stainless steel pipe and the brass isolation valves to perform the yearly descale.

Title: Efficient and Reliable Hot Water Solution
Review: 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.

Title: Efficient - Easy Install
Review: Installed June 2022INSTALL NOTE - I am not a plumber and this stretched my mechanical DIY-er mentality, but I did install this on my own: be careful if you choose to install this on your own. I chose NOT to do the electrical upgrade required on my own - the risk of not getting that right was too high, so I paid my electrical contractor to upgrade the box for the 3 x 50 amp breakers - NO REGRETS!I knew my 55 gal standard electric water heater was not going to last much longer due to the units age AND the fact our local city water is awful with calcium and build up. I researched the available setups and units ad nauseum, and went with this unit: the brand recognition and reputation, the size due to our house and expectation that we will eventually sell it. When I bought this unit, it was one of the larger of its type and was actually cheaper than if I went with a standard water heater to match the one I was getting rid of.First, the drop in electric usage has about paid for 50% of the unit cost over the last year - yeah, THAT MUCH! Results will vary I am sure, but its just my wife and I in 2200 sq ft house, so the fact it runs "on demand" just makes sense. Another way to measure savings: I am all electric in this house and during extreme seasonal weather I could easily see a monthly electric bill $250-300, using either my heat pump or my additional heat source in the house. I have yet to see a monthly bill above $180 (Ohio weather from summer 90s down into the single digits in the winter).The temp control is amazingly simply - we found 115 works fine and can take a long hot shower. But I can walk out and dial it up or down if I chose.The install (outside of the electric) was not too bad. I have PEX plumbing in my house, so it was a no-brainer to use that with the majority of this project. I spent the money to buy heavy brass shot off valves (probably overkill) for the IN/OUT inlets on this unit. It will make a difference if I ever have to repair or replace the unit: I can easily isolate the unit from the flow of water.Assuming we will move in the future, I will be looking for a house that either has a tankless or can be upgraded to tankless: its a great decision and works amazing.

Review: Hasta ahorita he tenido un mes este producto y ha funcionado a la perfección. Si requiere una instalación eléctrica especializada pero el flujo de agua es constante y alto. No ocupa nada de espacio y puede estar en el interior de la casa en un espacio pequeño. Además es muy silencioso.

Review: I live in a mobile home, not a lot of space. The 29kW work well for on shower and 2 sinks and free extra space for storage. Be aware to buy the right one, you will be disapointeed (I try a 18kW, is not enough). I live in Quebec City, lower than 29Kw will not do the job. Water is 4 celcius in winter.
