February 26, 2020 By Taylor Simons

For those of you looking into a new electric tankless water heater, take a look at the following review for the Stiebel Eltron Tempra 24 Plus to learn if this model is the right heater for your home. In this review, we will discuss the general features of the Tempra 24 Plus. As well as take a look at the specs and weigh the benefits and disadvantages of this tankless water heater. It is all in an effort to help you make the best decision for your home!

Stiebel Eltron Tempra 24 Plus Tankless Water Heater Overview

The Stiebel Eltron Tempra 24 Plus is an innovative electric tankless whole-house water heater. There is no venting required with this unit, and it also features a compact design to allow it to take up as little room as possible. Though it is not Energy Star rated, the product is intended to be energy-efficient so that you don’t see much of a hike in your bills. It is estimated that this model can save an average of 15% – 20% kWH when compared to conventional tank water heaters.

The Tempra 24 Plus, likewise with all Plus models from Stiebel, utilizes the Advanced Flow Control. With this type of control, the flow of water is lower if the demand of this tankless water heater is more than it can handle. This Advanced Flow Control capability places precedence on the temperature over the water flow for the sake of your comfort.

In addition to the Advanced Flow Control feature, the Tempra 24 Plus has some safety features that extend its life and keep it functioning no matter how heavy you decide to use it. This safety element for the electric tankless water heater comes in the form of a feature known as overheat protection.

Lastly, the Tempra 24 Plus electric tankless water heater is very user-friendly. For one thing, it features a digital temperature display that is straightforward to use. With that LED display, you can control an output water temperature range of around 86ºF – 140ºF. There is even an option for preset temperature memory so that your choice of temperature is always available. The minimum flow to activate the electric tankless water heater is 0.50 GPM. Other user-friendly designs include the hinged cover.

Stiebel Eltron Tempra 24 Plus – Pros and Cons

Pros
Produces a good amount of hot water for more than one faucet at a time. This makes the model an ideal choice for multi-family households.
Has a quality, sleek design that is compact and takes up a minimal footprint in your home. This also means that there are fewer raw materials used when manufacturing it so that it cuts back on waste.
Made of high-quality components such as solid copper and heavy-duty electronics.
Cons
There are some downsides to the Advanced Flow Control in that it can be a difficult, slow process to fill a bathtub if the function decides to kick in.
There are complaints that this device is not very energy-efficient. Some users have noted a large power draw that can negatively impact your bill.
There are some issues with inconsistencies with the water temperature in spite of it being designed to keep water hot. This is mainly seen in shower use, but at times, the water temperature can change from hot to warm the longer it’s used.

Users’ Opinion

As we went over details about the Stiebel Eltron Tempra 24 Plus, we came across a number of important user comments about the model that can further help you decide whether or not the unit can benefit your home. In an effort to get a more unbiased review, we examined three separate user opinions:

Positive: This short review discusses that the unit can be simple to install along with another person. They also speak about how they can run a washing machine at the same time as someone showering, but they do make note that they didn’t have it long enough to see any difference in the bills.

Neutral: Most of this review is positive as they mention things like how easy it is to adjust the temperature and the simplicity of installing it. They even claim that it may have slightly reduced their electric bill. However, they did mention that the temperature isn’t always as steady as it can be with a tank heater.

Negative: Another short review, but the user mentions issues with the Advanced Flow Control feature. They claim that they have to wait almost 15 minutes or so to fill their bathtub compared to how they only had to wait a few minutes to fill a tub prior to installing the Tempra 24 Plus.

Conclusion

The Stiebel Eltron Tempra 24 Plus is a sleek electric tankless water heater meant for whole-house use. Though some have concerns about how it can restrict flow if the demand for the water heater becomes too much, it can serve as a benefit as you’ll maintain a good water temperature even if you’re using multiple faucets. Also, for a similar product, you can check out the Stiebel Eltron Tempra 29 Plus.

In conclusion, we feel the benefits outweigh any concerns about the Tempra 24 Plus. It saves space, produces a good amount of hot water, and it’s easy to use and adjust the temperature to your liking. If you have any thoughts about this unit, let us know about them in the comment section.
