Voltage, or volts, is a measurement of the difference between two electric fields (in heating terms, the difference between the Earth's electrical field and the electricity running through your wires).
The Tempra® series has been redesigned completely inside and out - upgraded heavy-duty electronics, a simple single flow sensor design, a hinged cover for easy access, and Advanced Flow Control for the Tempra® Plus. Welcome to the next generation of German quality.
Unlimited Supply of Hot Water
The Tempra® continually heats water instantaneously as you require it - and only when you require it. The Tempra® unit completely replaces a conventional tank heater with no disruption to your comfort and hot water needs.
Tempra Plus Featuring Advanced Flow Control
The Tempra® Plus is the most technologically advanced tankless water heater available on the market today. Advanced Flow Control is exclusive to the Tempra® Plus and ensures a constant temperature output no matter how great the hot water demand is.
Advanced Flow Control technology works by automatically adjusting the flow of water to eliminate unpleasant temperature fluctuation. What that means to you is a consistently satisfying experience every time, all the time!
Save Energy and Reduce Your Electric Bill
Electric tank type water heaters are subject to stand-by losses which amount to 15 - 20% of the kWH used. In addition, water in a tank has to be heated hotter than necessary to account for these stand-by losses.
Changing to a tankless system like the Tempra® eliminates these problems and results in typical savings of at least 15 - 20% on the hot water portion of your electric bill.
Control Temperature Simply By Setting a Dial
Set the knob on the front cover and enjoy water temperatures between 86°F (30°C) and 140°F (60°C). Change the desired temperature at anytime. Advanced microprocessor technology ensures that the water temperature never deviates from the set point.
Stiebel Eltron has an enviable track record of engineering excellence and product quality. The three years parts warranty is unique in the industry. You can depend on the Tempra® for many years to come.
Sleek Design Fits in Anywhere
The Tempra® takes up considerably less space than conventional tank type water heaters and saves valuable living space.
No Venting Required
The Tempra® has several advantages over a gas-type tankless water heater. Compared to many similar gas tankless models the Tempra® is less expensive to purchase. Installation is also much simpler and cheaper since it is not necessary to vent a Tempra® to the outside.
The venting that a gas unit requires causes anywhere from a 10 - 20% efficiency reduction from heat escaping out the exhaust pipe. Furthermore, for every cubic foot of gas burned, roughly two cubic feet of air have to be mixed in to create ideal combustion. In a cold climate, this hurts efficiency further.
When a gas unit fires it draws in air around it, heats the water, and then expels warm exhaust outside. Since no house is airtight, this suction action causes a drafting condition where cold air from the outside seeps back in through door cracks and other parts of the house that may not be airtight.
By nature of the design, the Tempra® is nearly 100% efficient; converting 100% of the electrical energy it consumes into heat. All that heat is then transferred to the water - none is lost to the outdoors.
Superior, reliable performance
The Tempra® has several temperature and flow sensors which feed their readings into the unit's proprietary microprocessor control. Heating elements are engaged in stages, achieving the temperature you desire. The Tempra® continually monitors the water temperature it produces.

Came from Aquastar natural gas tankless water heater that gave us consistent problems x3 years. Research lead to conclusion that electric, used in Europe and South America, is only thing simple enough to work low-maintenance. Kind of confusing to look at this amazing little box. The thing is literally the size of a large VCR! Once you open it up, it literally resembles some sort of explosive device. But the internal wiring all uses thick gauge and everything gives the appearance of typically meticulous German engineering. Unit required 2 60amp breakers and the accompanying 6/2 gauge wiring. Connections are straightforward, but I let electrician work with higher amperage since I don't know all the rules. Unit went close to power box so only took about an hour or so. Connecting 3/4" pipe thread to unit was pretty easy as well. The thing was up and running right after this. It has a little rotary dial that coorelates to the digital water temperature. We ended up putting it on 116F(it goes to 140F). 4 weeks in, the unit pumps out tons of very hot water(I like hot showers) for as long as you want. Zero problems keeping up with the demand of our one shower, 2 sink condo - although I still have no idea how something so small can do this so well! Previous reviewers recommend water softener to prevent calcium buildup. Apparently all these things are really big so we don't have much room for one. We plan on doing the 8-12 month, hour-long vinegar flushes instead. Plan to spend $90 for sump pump from hardware store if this applies to you. Very impressive product!

I purchased my stiebel heater about 20 months ago and have installed and reinstalled four of these due to defects which the company can't figure out. This heater looks well built however it is not repairable at all by the homeowner just replaceable. It never performed as described and as far as saving me money on my light bill that's a myth as well when it malfunctioned actually ended up being more expensive! I was impressed at first but after I believe four months ( that's how long the first heater last) that quickly went away. I will say the company has been good about sending out the replacement units however the cost of installations is not covered so that's an inconvenience for my huge inconvenience! Do some research before you buy you might want a heater that can be repaired. After further research I have replaced my tempra 24 with a competitors heater that's actually repairable, half the price and not a one year not a three year but a lifetime warranty that tells me they believe in their product!!!

Comments about Stiebel Eltron Tempra 24 Plus Electric Tankless Water Heater:
I bought this Stiebel Eltron water heater for use in my own home. I regularly see people that want to install a whole house water heater and then buy the cheapest heater they can find. Certainly, there are more expensive heaters, but through my work I have never seen a heater with better quality. Certainly, there are less expensive heaters, but none of them are built to a high quality standard.
Bottom Line Yes, I would recommend this to a friend

Installed this on-demand unit to avoid the standby losses associated with an oil-fired system. (Also to get away from oil-dependence.) Unit works great. It's easy to install and simple to operate.

Works as advertised, easy to plumb to. Electric hookup was the most complicated part for a DIY instal. Using this in a single family dwelling with two adults and one shower, three sinks, dishwasher and clothes washer. Since we can be reasonable about how we use these things simultaneously we have not had any issues or had to adjust our lifestyle. Looking forward to seeing how this improves our monthly electric bills.
It works as advertised
from West Richland, WA
The Tempra 24 Plus was easy to install and worked the first time I tried it. I did need to run two new 60 amp circuits to the unit, but my utility room is within 20' of the main breaker box and I had enough spare slots to add two new breakers. I live in the pacific northwest and was concerned about a tankless hot water heater with our cold ground water. However, it worked fine. I've tested it with one shower, and the water is plenty hot.

I installed this unit in my 3 bedroom, 2 bath home approx. 2 weeks ago. We are TOTALLY satisfied with this water heater. You would never know its there (except for the endless hot water). Operation is silent, installation was easy and we couldn't be more pleased. We can run two showers at a time with no problems other than a small adjustment in the cold water faucet (our water pressure is not really great). Pexsupply.com provided outstanding service; the water heater arrived much more quickly than I expected and the price was very reasonable. I highly recomment this unit and Pexsupply.
So far excellent product

Very easy to install and operate.
from Foley, Al
Installed this product 4 weeks ago and it works great, plenty of hot water that never runs out. A previous review said that it took him an hour and 1/2 to install - not too sure about that!! It took me a day to run the 6/2 from the breaker box, into the attic, cut away the sheetrock, pull the wire down, patch and paint. However once that was done it took less than 2 hours to connect the electricity and replumb, real easy - I used the Shark Bite connectors from [@], very cozy indeed. Flipped the breakers, set to 120 and off it went, I noticed no difference at all in the hot water flow. Now I am not paying to keep 50 gallons of water hot 24/7.
