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, patented in Germany and exclusive to Stiebel Eltron 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 Tempra 24 Plus provides hot water at a consistent temperature for up to 2 bathrooms in warm climates, or 1-2 bathroom in cool climates. See sizing to determine which model is best for you. 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.
Features

This Tempra Plus model has German patented Advanced Flow Control that automatically reduces output flow to maintain temperature if demand temporarily exceeds capacity.
Professional installation recommended
Supplies endless hot water at a constant and steady temperature from 68 to 140°F (20-60°C) that can be set on the front panel digital display
Tempra tankless electric water heaters must be correctly sized and you should consult the sizing guide to determine the correct model for you
99% efficient and typically result in savings of 15-20% in comparison with electric tank water heaters
Requires 240 Volt or 208 Volt electric service, and has a maximum output of 24,000 Watts at 240 Volts or 18,000 Watts at 208 Volts
Smart microprocessor technology unique to Tempra water heaters delivers steady water temperature even when flow rate vary as taps are adjusted
Must be installed vertically, water fittings pointing down, with detachable connections such as braided flex connectors to allow periodic filter cleaning and flushing for scale, and an anti-scale filter is recommended if hard water is present
Requires a minimum of 150 Amp total service to the residence, with 2 separate dedicated 50 Amp DP breakers and 2 separate runs of 6-gauge copper wiring for the Tempra 24 Plus itself
