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. Tempra 29 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.

A tankless water-heating system is not unlike any other major appliance.

The My PlumbingStuff Tankless Water Heater Flushing Kit is perfect for maintaining any tankless-style water heater. It includes 5-foot SS hoses, a 32-ounce bottle of FLOW32 Descaler, a Zoeller 42-0007 Floor Sucker pump, and a 5-gallon recycled bucket.
