The Stiebel Eltron Tempra 12 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. Tempra 12 Plus will typically use 15-20% less energy compared to conventional electric tank water heaters. 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. Tank water heaters that use gas or oil are even less efficient, because they also lose heat through their vents to the outdoors. Our tankless water heaters do not need venting, and will not store hot water, waiting for you to use it. They operate on-demand to provide continuous and endless hot water when you need it, and not waste energy when you don’t. CERTIFICATIONS INCLUDE – ANSI/UL Std. 499, CSA Std.

Product Description

Chronomite was the first to patent a microprocessor technology which allows for a pre-set or controlled output temperature that delivers unlimited hot water without risk of scalding-in two seconds as opposed to the six seconds offered by other tankless water heaters. Chronomite is installed at point of use and is only operational when hot water is requested, thus dramatically reducing hot water delivery time and inefficient use of electricity.
