• Unlimited Supply of Hot Water: Keeps heating water instantly as you require. The Tempra™ system completely replaces a conventional tank heater with no disruption to your comfort and hot water needs.
• Saves Energy and Reduces Your Electric Bill: Electric tank type water heaters are subject to stand-by losses which amount to 15 - 20% of the kWH used. Changing to a tankless system results in savings of 15 - 20%.
• Control Temperature Simply by Setting a Dial: Set the knob on the front cover and enjoy water temperatures between 86°F (30°C) and 125°F (52°C). Change the desired temperature at anytime. Advanced microprocessor technology ensures that the water temperature never deviates from the set point.
• Sleek Design Saves Space: The Tempra™ takes up considerably less space than conventional tank type water tanks and saves valuable living space.
• Proven Reliability: STIEBEL ELTRON has an enviable track record of engineering excellence and product quality. The three years parts warranty is unique in the industry. You can depend on the Tempra™ for many years to come.
