Stiebel Eltron Tempra 36 Plus Review – Features

The Stiebel Eltron Tempra 36 brings the following features to the table. 

Massive and On-demand Hot Water Flow to Fulfill Your Needs  

As mentioned earlier, the Stiebel Eltron Tempra 36 is of the highest capacity in the series, while the other models are Tempra 12, 15, 20, 24, and 29 Plus. The number represents the kW output of the respective model. As you can easily discern, the Tempra 36 Plus brings the maximum output and flow rate of hot water.  The powerful tankless water heater can instantly provide a huge flow of 7 gallons per minute of hot water if the inlet water temperature is 70 degrees Fahrenheit. Hence, it is usable as a whole-house unit supporting several showers and sinks to run hot water simultaneously. However, the water flow rate drops in the colder regions.  Therefore, it is commendable to make your purchase after consulting the average temperature map published by the manufacture. Nonetheless, even at temperatures as low as 40 degrees Fahrenheit, the tankless water heater supplies 3.8 gallons per minute, which suffices for two hot showers at the same time.  

Patented Advanced Flow Technology for Consistent Temperature

Stiebel-Eltron-Tempra-36-Plus Like the other models in the series, the Stiebel Eltron Tempra 36 Plus features the exclusive Advanced Flow Technology. What difference does it make, you ask? Well, the feature comes in handy if the water temperature fluctuates in your area fluctuates a lot. Such showers can be extremely discomforting to take.   In that case, the water heater still provides a steady stream of hot water. So, if the chilly water supply is high, the Tempra 36 Plus reduces the flow to keep the water hot. Contrarily, it maintains a consistent heat if the water supply is under-capacity. Thus, you get hot water the whole time you open the tap or shower.   

High Energy Efficiency thanks to Self-modulation

It is an undisputed fact that tankless water heaters immensely reduce electricity costs. The Tempra 36 further corroborates the statement as it boasts a 99 percent energy-efficiency. The tankless water heater saves a huge chunk of energy via self-modulation to heat the water only when it’s required.  Hence, you end up saving a lot of money on electricity bills. The manufacturer claims that you can reduce the energy-associated costs of heating water by 15 to 20 percent. You can save that amount for the rainy days. Not only it saves money, but it also leaves you with a lot of space, thanks to the sleek design. 

Desired Microprocessor-controlled Temperature and Digital Display Panel

The tankless water heater comes with a microprocessor-regulated control over the water temperature. Stiebel Eltron Tempra 36 Plus keeps itself from overheating with its anti-scalding feature. You can precisely set your desired temperature using the dial at the front. The temperature ranges from 86 to 140 degrees Fahrenheit. You can set the temperature and forget about it. The unit will make sure that you receive the adjusted temperature, recall the Advanced Flow Technology. Also, the Tempra 36 Plus makes things convenient with its digital display. It is needless to say that greater temperatures mean higher consumption, and thus, costly bills. 

Warranty and Customer Support

 Stiebel Eltron offers two warranties on the product. One is a 3-year warranty on the heating and electric parts, and the other is a 7-year warranty on any leakage on the heater. As long as you follow the provided instructions, you won’t void the warranty.

 Final Verdict 

If you put everything together, you would come to realize that the Stiebel Eltron Tempra 36 Plus is a remarkable tankless water heater. With its bigger size comes greater output in the form of uninterrupted, instant, and on-demand hot water flow. Hence, for a moderate climate and a large house, it makes for an impressive whole-house unit. However, if your needs are less, then it is not wise to invest in such a massive water heater. You should check out other models in the Tempra Plus series. They are just as good as this one, and they offer a low output. Nonetheless, if you have higher demands for hot water, you shouldn’t shy away from this model.
