Stiebel Eltron Tempra 24 Plus Electric Tankless Water Heater

The Stiebel Eltron Tempra 24 Plus Tankless Water Heater is equipped with exclusive Advanced Flow Control German patented technology, invented by Stiebel Eltron, to automatically maintain water temperature for constant comfort. It will reduce the flow slightly if the hot water demand exceeds its capacity, ensuring that hot showers will never be interrupted. Compared to conventional electric tank water heaters, the Tempra 24 Plus typically uses 15-20% less energy, and the potential for energy savings can be significantly higher, depending on personal home usage habits.

Conventional tank water heaters continually store hot water, resulting in 15%-20% of the total energy consumed being lost to the surrounding environment, a phenomenon known as standby heat loss. Tank water heaters that use gas or oil are even less efficient, as they also lose heat through their vents to the outdoors. In contrast, the Stiebel Eltron tankless water heaters do not require venting and do not store hot water, operating on-demand to provide continuous and endless hot water when needed, without wasting energy when not in use.

The Tempra 24 Plus has been certified to meet ANSI/UL Std. 499, CSA Std. C22.2 No. 88, ISO 9001, and is WQA tested and certified against NSF/ANSI 372 for lead-free compliance.
