|Incoming Water Temp:||Flow Rate (GPM)|
The Tempra 24 Trend is also frequently used in warmer southern climates for applications requiring higher flow rates of up to 5 gallons per minute (large Roman-style or jacuzzi tubs, simultaneous showers, etc.), as well as for commercial applications.
Like all Tempra Series tankless water heaters, the Tempra 24 Trend features true microprocessor-controlled temperature regulation and a dial selector which allows you to set the desired output water temperature at any level between 68 and 140F (20 and 60C). It is one of the only tankless water heaters on the market that features a true thermostatic temperature control and full power-modulation based on both the incoming water temperature and the water flow rate.
The Tempra 24 will automatically adjust its power output to accommodate changes in the incoming water temperature and flow rate so it can precisely maintain the desired output temperature. The result is the most precise temperature control of any tankless water heater on the market today!
Electric tankless water heaters are a lasting trend in the water heating industry that is here to stay.
The trend towards increased energy efficiency is here to stay. Join the Tempra trend today.

How it works
The Stiebel Eltron electric tankless water heater is a marvel of technology and engineering - overflowing with technology, yet packaged in an intelligent, simple design. It heats water entirely on demand, only when it is needed.
When a hot water faucet is turned on and the water begins to flow, a sophisticated flow sensor detects that hot water is being demanded and turns the water heater on. Instantaneously, a series of sensors gather information about the flow rate of the water and the incoming water temperature. This information is sent to a microprocessor which calculates the amount of power needed to heat the water to the temperature set point. The water flows through the internal heating modules and exits the unit at the desired temperature. The start-up process takes a couple of seconds. A convenient thermostatic control on the front of the unit allows the homeowner to select an output temperature between 86 and 140F (30 to 60C) [Note: some models are designed for maximum output of 125F (52C)].
The sensors continue to monitor the water flow rate and incoming water temperature as long as the water is running. They constantly send data to the microprocessor so power to the heating elements can be modulated in accordance with changes in incoming flow rate and temperature. If, for instance, the flow rate increases because a second demand for hot water in the home is initiated, the unit will increase its power output to maintain a consistent and precise output temperature.
The tankless water heater will remain on until the hot water faucet is closed. As soon as the flow sensor detects that water has stopped flowing, the power to the unit is completely turned off.
All Stiebel Eltron Tankless Water Heater Tempra Trend Series water heaters are manufactured in Germany in one of the world's only ISO-9001 certified tankless water heater manufacturing plants by a company that has been around since 1924!
Please see the internal views of the Stiebel Eltron Tankless Water Heaters below for more details. All of the models utilize the same parts and technology, but have varying sizes and numbers of heating modules.
|Electronic Control Module
Sophisticated microprocessor-controlled electronics adjust the power output of the heating modules based on flow rate and incoming water temperature to precisely regulate the output water temp.
The muscle of the system! A series of very high output heating modules (up to 3, depending on model) are used to heat the water as it passes through the heating chambers of the water heater. Each heating module features multiple heating elements. The heating chambers are manufactured with copper - no cheap plastics here!
A sophisticated flow rate sensor delivers important data to the microprocessor on a continuous basis - this data is used by the microprocessor to calculate the power level of the heating modules that is necessary to heat the water to the set temperature.
|Safety Thermal cut-off
Safety first! Each heating chamber is protected by thermal limit switch, a back-up safety feature that will automatically turn off the heating module if a potentially unsafe output water temperature is reached. This reduces the risk of scalding injuries for children and the elderly, and protects the unit from damage if the microprocessor-based thermostatic control fails.
Set it and forget it - use the simple dial control to raise or lower the temperature setting. The temperature can be set at any level from 86F (30C) & 140F (60C) [up to 125F or 52C on Tempra 12, 15, and 20]
Working in conjunction with the flow sensor, a series of temperature sensors deliver important data to the microprocessor on a continuous basis so that the unit can acurately maintain the set output water temperature.
Convenient terminal blocks are provided to ensure a quick, simple, and safe installation. Installation by a licensed electrician is highly recommended.
|Sturdy Hinged Steel Case
All Stiebel Eltron Tempra Trend Series water heaters are housed in a sturdy steel case with built-in wall mounting brackets. Many competitors use flimsy light-gauge aluminum cases or even plastics. Tempra Trend models feature a convenient hinged case for easy access.
|Inlet Water Filter
The inlet water pipe includes a small screen filter that ensures that no debris is able to enter the system. This filter can be periodically cleaned for optimal flow performance.

Tankless water heater
Good product, had previously purchased from Tankless in Florida, which worked well for 8 years. Installation not to difficult, following the instructions. I chose product for good price and European experience with good workmanship. hope this one will last long. - Roger
When my home was built 25 years ago, this was the hot water heater. You might be thinking that a hot water heater should justifiably last an easy 25 years. I have well water, and 1 filter before the heater. This statement says more. I absolutely had to get the same one. It is a little taller so a tiny bit of plumbing and tada, easy to install. I am pretty old fashioned so the extra options are not important to me, but all I did was set it to 110 degrees with the dial, done. In 25 years I will get another if it is needed. I had a GE tank break after 2 years and the insurance stuck it to me. Personally I am so very sick of garbage on the market. This unit in my home has a proven track record and I am all about proof. - Steve A
Other Tempra Trend Series Reviews
We love our Stiebel Tempra 20. Have paired it with a Hague water softener and are very pleased with the result. - Sandpiper
tankless hot water heater
I got it very fast and we replaced our old one of many years, It works great, no problems. - john c
Tempra 29 Tankless Heater
Simple to install (already had electrical in place), performs as advertised. So far, very pleased. - Bob P
Installed the unit according to the directions and it did not work at first. I think because the water pressure needed time to reach normal in the unit. It now works fine to heat our master bath fixtures - Stephen K
E Tankless Water Heater
Love it, works great & company very helpful when ordering. - Janice
stiebel eletron tempra 15 trend tankless water heater
Heater is working flawlessly. Excellent quality. Very good instructions for installing heater. The unit is for one full bathroom (tub and sink). I live in southern Maryland and the water heater keeps the water a constant 115 degrees at 2.8GPM with no issues. Thanks - Vincent Beatrez
Finally we have UNLIMITED Hot Water, Thank you e-tankless!
Our water heater is in the garage and our Master Bath is on the other side of the house. We have a Taco recirc pump but our 66 gallon water heater tank couldn't provide enough hot water for long relaxing showers. We bought the 29B (refurb) from e-Tankless. It looked brand new, came in the original packaging. It was fairly expensive ($2,100 USD) to run new 125A service to support this water heater but I am so glad we did. We now have endless hot water! I would recommend buying the isolation valve kit so you can easily flush the unit annually. I would highly recommend e-tankless! - Todd Simmons
My old waterheater was in my attic which daily made me nervous to have 50 gallons that could leak at any time. I upgraded to tankless and I am very impressed the hot water works better much better now. - Shawn Lawson
Tankless So far it’s working great. If it goes well I will order four more for my other units - Mario Tridente
Excellent solution for on demand hot water
This purchase is a replacement for the previous model of the same specs we had installed in our condo about 15 years ago. The electrical elements do wear out in about 15 years, so we installed a replacement unit. The new unit is smaller and has a better screen than the old one. It works wonderfully, and we are just as happy with this one as we were with its predecessot. -
excellent product. easy to operate, user friendly - Chep Hon
Replacing on older Steibel Eltron unit
After about 15 years of faithful service my older model Steibel Ultron tankless water heater stopped heating the water effectively (lime scale). This new unit (Tempra 29) is the newest edition of the prior model. No issues installing although the size and spacing of the water inlets/outlets differed meaning a little extra work. New unit works like a charm now - Jeff
We had another manufacturers units for 10 or more years. Those units had plastic heat chambers that both began to leak at a mold seam. I chose the Steibel unit primarily because of the copper tank. The instillation was very easy and the single unit is able to keep up with our DHW needs. My only comment is that I wish E-Tankless Water Heaters had offered a faster shipping method. I would have gladly paid extra to have the unit faster than the 2 weeks it took to get it from BC to NB. I should have inquired about shipping options. We were looking at Christmas without hot water, thankfully the unit arrived on the 23rd and I was able to install it the next day. Could not be happier with the overall experience and product. - Richard Harris
