Features Of Stiebel Eltron Water Heaters

Saves Energy

Tempra is wildly popular for having the latest technologies that not only guarantees amazing performance but also reduces energy usage more than 20%. Apart from this, these tankless are upto 100% energy efficient and heats water only when it is needed. Therefore, there is no standby heat loss. 

Precis Temperature Control

Thermostatic temperature control is another wonderful feature that gives you correct, persistent and reliable temperature to ensure the comfort around the clock. It is especially designed to handle the inlet cold water. One of its biggest strengths is its ability to work with a solar heating system along with pre-heated water up to 131 F. 

Advanced Technologies 

Thanks to the advanced microprocessor technology and temperature sensors for giving you the precise authority to control the temperature. The temperature easily sets between 86 F to 140 F. The best part is the model stops fluctuation in temperature and adjusts the power to ensure the steady temperature. As a result, you do not experience any discomfort even if there is change in water flow. 

The Tempra series gives outstanding performance by saving the electricity and space both. The advanced technology makes sure a smooth shift from minimum to maximum power transfer when the temperature is set at desired level. 

Sleek Design and Compact Size

Unlike traditional tank-type hot water heaters, the Stiebel tankless heaters have a sleek design and durable case that make installation super easy.  Due to the compact design, they easily mount on the wall, fit under the sink or cabinet or even in short space.

Thus you do not have space issues with Eltron tankless heaters. If you have a space issue and are looking for a compact sized tankless heater, for your home, business, apartment, office, condo, or cottage, Stiebel Eltron fits the bill for sure.

Installation Of Stiebel Eltron Tankless 

There is no second opinion that the installation of electric tankless heaters is far easy as compared to gas tankless water heaters. But we must not forget the fact that electric heaters might need to update your existing electric system. The reason to upgrade is that electric heaters require high amps to work properly. 

Stieble Eltron manuals have rich information regarding installation and maintenance of the units. If you are a complete noob, it is recommended to go for professional installation only.   

Series of Stiebel Eltron

Stiebel Eltron offers a double series of Tempra. They are:

  • Tempra Series 
  • Tempra Plus Series

There is a considerable difference between the features of above two mentioned models. The Tempera series includes medium sized tankless water heaters ranging from 9 to 24 kW. Whereas the Plus series have powerful units with high power including 28 and 36 kW. 

Some models with low flow rate are used as point of use applications. The most important thing to know before going to choose tankless is to sort out your requirements, temperature of inlet water, and the temperature you want. 

On the other side, the large models have the advanced features with larger capacity to handle the excessive demand of hot water. Moreover, they are capable of delivering unlimited hot waters to multiple showers simultaneously. 

Stiebel Eltron Tempra Series

The Tempera series makes a sensible choice in hot areas of the USA. In Florida and Caribbean they serve as whole house heaters for small families with one bathroom. On the other side, in cold areas, they are perfectly used as point of use water heaters for low flow appliances such as a kitchen or bathroom sink. 

The amazing fact about Tempra 12 / Plus is its low activation rate which is 0.37 GPM while all other electric models require 0.5 GPM to activate. Tempra 12 and Plus works with one heating module and delivers upto 3 GPM when the temperature rise is 27 F to a maximal degree. 

Going further, the Tempra 15 and Plus have power ranges from minimum 10.8 kW to maximum 14.4 kW and require 208 V and 240 V respectively. This model featured two heating modules. Therefore, its flow rate is excellent (3 GPM) when temperature rise is 33 F. 

Talking about Stiebel Eltron Tempra 20/ Plus and Stiebel Eltron Tempra 24 Plus, they are capable of delivering 3 GPM hot water with higher temperature rise. When there is low temperature rise i.e 29 F. These units make an ideal choice as whole-house heaters for the southern part of the USA where temperature is likely hot. 

Tempera 24 has a moderate flow rate i.e 4.5 GPM and thus recommended for medium sized homes with 2 to 3 washrooms. 

Tempra Plus Series

Stiebel Eltron Tempra Plus

Tempra Plus is the wonderful edition of the Stiebel Eltron tankless heater. They are super advanced units because of the unique technologies such as microprocessors and the Advanced Flow Control Technologies. 

The Advanced Flow Control is a super cool feature that automatically decreases the water flow when demand increases instead of delivering the cold water. Meanwhile the desired temperature remains the same. Undoubtedly, this is an exclusive feature in Tempra Plus models and not found in any other tankless brand making Stiebel Tempra the best among all. 

Stiebel Eltron Tempra 29 Plus and 36 Plus are the heaviest and strongest models that fulfills the large demand of hot water. But at the same time they draw a high amount of electricity to carry out operations. 

Both models are equipped with three heating models. On 240 volt, they exhibit maximum power of 29 kW and 36 kW respectively. When the temperature rise is 66 F the Tempra 29 delivers 3 GPM. As temperature rises to 44 F, it offers 4.5 GPM. So, I would recommend this model if you live in colder regions and have a medium family of 4 to 5 members. 

36 Plus is the biggest model of the Eltron family and intelligently offers 3 GPM at the 82 F temperature rise. Similarly, when the temperature rise is 55, the flow rate is 4. GPM. Therefore it is highly recommended in the areas with extreme cold inlet water. This unit easily handles 4 bathrooms without running out of hot water.
