Stiebel Eltron Tempra 36 Plus – 2020 Review

February 27, 2020 Stuart Trevino Leave a Comment

The Stiebel Eltron Tempra 36 Plus is a top-performing electric tankless water heater that continues to be a popular choice for those in need of a whole-house water heater. In the following article, we take a deeper look at the unit, going over how it works, the top features, and the good and bad things users have discovered about it. This is all done to provide you with as much information as you need to decide on whether or not to purchase the Tempra 36 Plus.

Stiebel Eltron Tempra 36 Plus Tankless Water Heater Overview

A powerful electric tankless water heater, the Stiebel Eltron Tempra 36 Plus features smart microprocessor technology so that you can set the temperature and actually receive that temperature each time you use the hot water. Compared to other water heaters, there is a minimum chance for uneven temperature. To try to maintain that temperature, this electric tankless water heater uses Advanced Flow Control that cuts back on the water flow once the demands for the heater grow too much.

When it comes to actually set the temperature, it is a simple process to do thanks to the digital display. For the newer models of the Tempra 36 Plus, not only does it show the temperature, but it features two preset temperature memory keys, a way to monitor water flow, and a way to monitor cost savings.

The Tempra 36 Plus is meant to be relatively easy to install as long as you understand what you’re doing. You don’t have to worry about venting with this unit, and with it being so compact in size, you are able to install the unit as close as possible to hot water taps. The closer the Tempra 36 Plus is to hot water taps, the shorter the wait to receive that hot water.

This unit features a hinged cover so that it is easy to open. Inside, you will notice the high-quality components that help the Tempra 36 Plus maintain durability and function as well as possible. There are temperature and flow sensors, safety thermal cut-off, the copper heater, and an electronic control module. All of the heating is engaged in stages to help the unit achieve your desired settings as efficiently as it can.

Stiebel Eltron Tempra 36 Plus – Pros and Cons

Pros
This unit is designed compact enough that it can fit close to the hot water taps so that you can receive the hottest water as fast as it can go with little strain on the unit itself.
Adjusting the temperature, in particular with the newer models of the Tempra 36 Plus, is a straightforward process that even those who have never used such a water heater before can do.
This electric tankless water heater does do a fine job of sending hot water to multiple locations at the same time. Also, many claim to receive warmer temperatures at up to three faucets at a time.
Cons
The potential to waste water is high as, in some cases, the water may need to run high due to the minimum flow rate being so high.
There appears to be some sensitivity when it comes to installing the unit in spite of it being made with the purpose of being easy to install. If it isn’t precise, there is a high chance of the unit overheating and subsequently catching fire.
Since it is automatic that the flow rate will be restricted due to the Advanced Flow Control, some users claim to have problems getting consistent pressure and flow throughout their home.

Users’ Opinion

To gather as many different opinions about the Stiebel Eltron Tempra 36 Plus, we selected three different user comments about the unit that discuss some of the positives and negatives of using this device:

Positive: This first user noted at once that they did not see an increase in their energy bill while using the Tempra 36 Plus. They also make note that they did not notice any difference in the time that it takes for hot water to come out of the faucet. However, they did bring up tips about installing it properly.

Neutral: The user, in this case, does enjoy the unit and that they will buy it again, but they did speak about the restricted flow. In addition to that, the user said you may need professional help for the install process. However, they did say that they noticed their utility bill dropping while using this, and also the fact that they did not run out of hot water anymore.

Negative: This user started out highly enjoying the product and how well it functions. In fact, they bought two units, and even enjoyed how easy they were to store due to their size. However, their review changed as time went on and one unit failed completely. They believe it was due to not installing a filter as the unit that failed seemed damaged.

Conclusion

The Stiebel Eltron Tempra 36 Plus is a powerful, compact unit that performs well as a whole-house tankless water heater. It is generally consistent with the temperature that you preset, and it can deliver hot water to up to three faucets. If you like this particular brand you can also try the Stiebel Eltron Tempra 24 Plus tankless water heater.

In spite of the downsides to the unit such as issues with overheating and water waste, we highly recommend the Tempra 36 Plus to those who require high amounts of hot water usage such as those in multi-family homes with more than one bathroom.
