Description
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 12 Plus provides hot water at a constant temperature for 1 bathroom in warm climates and for 1 bathroom at a cabin or cottage in cold 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.
- Smart microprocessor technology unique to Tempra water heaters delivers steady water temperature even when flow rate vary as taps are adjusted
- This Tempra Plus model has German patented Advanced Flow Control that automatically reduces output flow to maintain temperature if demand temporarily exceeds capacity.
- Self-modulating technology saves energy by adjusting electrical usage
- Tempra tankless electric water heaters must be correctly sized and you should consult the sizing guide to determine the correct model for you
- This is a Tempra Plus model that incorporates an Advanced Flow Control to automatically reduce flow to deliver water at the set point if demand exceeds capacity
- Tempra tankless electric water heaters are 99% efficient and typically result in savings of 15-20% in comparison with electric tank-type water heaters
- Requires a minimum of 100 Amp total service to the residence, with 1 separate dedicated 50 Amp DP breaker and 6-gauge copper wiring for the Tempra 12 Plus itself
- Requires 240 Volt or 208 Volt electric service, and has a maximum output of 12,000 Watts at 240 Volts or 9,000 Watts at 208 Volts
- 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
- Flow rate you achieve from this or any tankless water heater depends on how powerful the unit is and the temperature difference between the incoming cold water and the hot water being delivered
- 99% efficient and typically result in savings of 15-20% in comparison with electric tank water heaters
- 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
- Professional installation recommended
