Stiebel Eltron 223425 Tempra 29 Plus Whole House Tankless Electric Water Heater 21 6 28 8 Kw 0 87 Gpm

The Stiebel Eltron Tempra 29 Plus Tankless Water Heater features exclusive Advanced Flow Control German patented technology invented by Stiebel Eltron to automatically maintain water temperature for constant comfort. It’ll reduce flow slightly if hot water demand exceeds capacity to ensure that hot showers will never be interrupted. Although, it’s possible to save significantly more energy depending on personal home usage habits. The difference is that conventional tank water heaters continually store hot water, and as a result, lose 15%-20% of the total energy consumed to the environment around them. This is called standby heat loss. Our tankless water heaters do not need venting, and will not store hot water, waiting for you to use it. CERTIFICATIONS INCLUDE - ANSI/UL Std. 499, CSA Std.
