Powerful output, compact design, remarkable energy-saving features! Our whole house electric tankless water heaters perform with the highest standards for comfort and reliability. Tempra Plus models feature Advanced Flow Control, exclusive to Stiebel Eltron tankless heaters. If hot water demand exceeds unit?s working capacity, Advanced Flow Control automatically maintains consistent temperatures by slightly reducing flow. Intelligent self-modulating technology continually ensures the least amount of energy is used to heat the water. The Tempra 15 Plus provides hot water at a consistent temperature for 1-1.5 bathrooms in warm climates, or 1 bathroom in cool climates. See sizing guide to determine which model is best for you (guide assumes 2 GPM or less per shower-head). Stiebel Eltron invented tankless electric water heating technology more than 90 years ago, and is still the industry pioneer and world leader. Our engineering and manufacturing tradition of excellence means you can depend on the performance and reliability of our products.
