The Engineering Authority: Why Professionals and Discerning Homeowners Choose Stiebel Eltron
When it comes to whole-house electric tankless water heating, the difference between a standard appliance and a precision instrument is felt every time you turn on the shower. While some competitive models are typical, Stiebel Eltron Tempra® Plus units are engineered for those who refuse to compromise on comfort, reliability, and technical superiority.
The Critical Advantage: Patented Advanced Flow Control™
The most significant technical gap between these two brands is how they handle high demand. Standard competitive units can suffer from temperature drops when multiple taps are opened, ie. when demand for hot water increases.
Only Stiebel Eltron provides the perfect temperature all the time with German Patented Advanced Flow Control™.
This proprietary technology automatically adjusts the flow of water to ensure that your set temperature is maintained, even if the demand exceeds the heating capacity. While other units will simply deliver lukewarm water, a Tempra® Plus ensures your shower remains at the exact degree you selected. This feature is available on all Tempra® Plus models, including the 20 Plus, 24 Plus, and 29 Plus.
