Item Notes: Powerful output, compact design, remarkable energy-saving features. Our whole house electric tankless water heaters perform with the highest standards for comfort and reliability. Tempera Plus models feature Advanced Flow Control, patented in Germany and exclusive to Steel Elton tankless heaters. If hot water demand exceeds 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. A Tempera 20 Plus provides hot water at a consistent temperature for 1-2 bathrooms in warm climates, or 1 bathroom in cool climates. See sizing to determine which model is best for you. Steel Elton invented tankless electric water heating technology more than 90 years ago, and is still the industry pioneer and world leader.
