Stiebel Eltron Tempra 29 Plus: What you need to know 

The Stiebel Eltron Tempra 29 Plus is a self-modulating tankless water heater. It can be used to heat water for an entire house, depending on how many faucets you have in your home, and also on the temperature of the ground water where you live. 

If you live in an area that has a ground water temperature of around 42 degrees Fahrenheit, then you can expect a flow rate of 3.1 GPM, but this will increase to a flow rate of 3.7 GPM if your area is 52 degrees, and up to 6 GPM if your area is 72 degrees Fahrenheit.

The Stiebel Eltron Tempra 29 Plus can reach a maximum power draw of 120 Amps using three 40 Amp breakers. In order for this tankless water heater to work, you’ll need a 240 Volt electric service.  

It’s worth noting that this tankless water heater must be positioned vertically and ideally somewhere where you can access its controls easily enough. 

Stiebel Eltron Tempra 29 Plus: Features 

The Stiebel Eltron Tempra 29 Plus has been designed to provide enough power to heat water for a range of moderately sized homes. Compared to other models we reviewed, the Stiebel Eltron Tempra 29 Plus has a modern design with a digital screen where you can easily see the status of the water heater. 

This tankless water heater features Advanced Flow Control which means you should technically never run out of hot water. The Advanced Flow Control works by automatically minimizing the output flow temporarily to maintain the temperature of the water. 

If you want to adjust the temperature of the water coming from the Stiebel Eltron Tempra 29 Plus, you can simply change it using the digital display. Temperatures range from 68 to 140 degrees Fahrenheit. 

Designed to be more energy efficient than water heaters that require a tank, tankless water heaters including the Stiebel are 99% efficient. What’s more, the Stiebel Eltron Tempra 29 Plus is self-modulating. What this means is that it uses only the minimum amount of energy required to work properly. This tankless water heater has been engineered to measure the temperature of the water it needs to heat up, and then adapt accordingly to heat without using excess energy. 

This tankless water heater won’t take up too much room and can be discreetly tucked away somewhere, as long as you’re still able to access its control panel. 

The Stiebel Eltron Tempra 29 Plus comes with a parts warranty of three years. However, other models do offer much longer warranties, including the EcoSmart ECO 27 which has a lifetime warranty.
