The Tempra series of electric tankless water heaters is the "Next Big Thing" for today's households.
Advanced technology, impressive energy-saving performance, and a compact design make it easy to consider a Tempra hot water system for your home. Stiebel Eltron Tempra 15 Plus is exclusively manufactured by Stiebel Eltron, a pioneer and leader in tankless water heating technology for the past 80 years.
- Featuring Advanced Flow Control
The Tempra Plus is the most technologically advanced tankless water heater available on the market today.
Advanced Flow Control is exclusive to the Tempra Plus and ensures a constant temperature output no matter how great the hot water demand is.
Advanced Flow Control technology works by automatically adjusting the flow of water to eliminate unpleasant temperature fluctuation.
What that means to you is a consistently satisfying experience every time, all the time.
- Unlimited supply of hot water
The Stiebel Eltron Tempra 15 Plus continually heats water instantaneously as you require it - and only when you require it. The Tempra unit completely replaces a conventional tank heater with no disruption to your comfort and hot water needs.
- Save energy and reduce your electric bill
Electric tank type water heaters are subject to stand-by losses which amount to 15 - 20% of the kWH used. In addition, water in a tank has to be heated hotter than necessary to account for these stand-by losses. Changing to a tankless system like the Stiebel Eltron Tempra 15 Plus eliminates these problems and results in typical savings of at least 15 - 20% on the heating portion of your electric bill.
- Sleek design saves space
The Tempra takes up considerably less space than conventional tank type water heaters and saves valuable living space.
- Digital Temperature Control
A digital temperature control allows you to get hot water at the exact temperature for maximum comfort. Advanced microprocessor technology ensures that the water temperature never deviates from the set point. Just set the knob on the front cover, check the digital temperature display, and enjoy water temperatures between 86 F (30 C) and 140 F (60 C). This is the perfect combination of functionality and efficiency - hot water on demand, at the temperature you desire.
- Better than gas
The Stiebel Eltron Tempra 15 Plus has several advantages over a gas-type tankless water heater. Compared to many similar gas tankless models the Tempra is less expensive to purchase. Installation is also much simpler and cheaper since it is not necessary to vent a Tempra to the outside.
The venting that a gas unit requires causes anywhere from a 10 - 20% efficiency reduction from heat escaping out the exhaust pipe. Furthermore, for every cubic foot of gas burned, two cubic feet of air have to be mixed in to create ideal combustion. In a cold climate, this hurts efficiency further.
When a gas unit fires, it draws in air around it, heats the water, and then expels warm exhaust outside. Since no house is airtight, this suction action causes a drafting condition where cold air from the outside seeps back in through door cracks and other parts of the house that may not be airtight.
By nature of the design, the Stiebel Eltron Tempra 12 is nearly 100% efficient; converting 100% of the electrical energy it consumes into heat. All that heat is then transferred to the water - none is lost to the outdoors.
- 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.
- Take the cover off
We have done our homework. As an international leader in the tankless electric water heating industry, Stiebel Eltron is proud to have pioneered this technology.
The company's German engineering and manufacturing tradition of excellence means that you can depend on its performance for many years to come.
- Seismic proof construction
The Stiebel Eltron Tempra 15 Plus is a tankless water heater system, and is thereby not subject to seismic code. There is no need for preventative construction, as required when using a tank type water heater.
- Superior, reliable performance
The Stiebel Eltron Tempra 15 Plus has several temperature and flow sensors which feed their readings into the unit's proprietary microprocessor control. Heating elements are engaged in stages, achieving the temperature you desire. The Stiebel Eltron Tempra 15 Plus continually monitors the water temperature it produces.
- No Venting Required
The units are electric and require no venting. This allows for more flexibility in the positioning of the units.
