Stiebel Eltron Tempra 29 Plus Whole House Electric Tankless Water Heater

 Stiebel Eltron Tempra 29 Plus Electric Tankless Water Heater — Endless Hot Water with Advanced Flow Control

Upgrade to the Stiebel Eltron Tempra 29 Plus, the flagship of the most trusted name in electric tankless water heating. Engineered in Germany and backed by more than 90 years of tankless innovation, the Tempra Plus delivers an endless supply of on-demand hot water while dramatically reducing energy use compared to traditional tank-style water heaters.

What sets the Tempra Plus apart from every other electric tankless water heater on the market is its patented Advanced Flow Control technology, which automatically adjusts water flow to lock in your exact set temperature — no more cold-water surprises mid-shower, even when multiple fixtures are running. Pair that with dual temperature memory presets and a sleek, wall-mounted footprint, and you have the most user-friendly whole-house electric tankless water heater available today.
