Stiebel Eltron Tempra 12 Trend Electric Water Heater

Product Info Advanced Flow Control™ is a standard feature in our Tempra® Plus models. If the demand asked of a Tempra® Plus is greater than the water heater can handle, Advanced Flow Control™ works by automatically reducing the flow of water slightly. Unlike water heaters from other manufacturers that can deliver colder water than desired, a Tempra® Plus automatically delivers slightly less water, but at the hot water temperature wanted. There is never a cold water surprise with a Tempra® Plus! Advanced Flow Control™ is exclusive to our Tempra® Plus models. No other manufacturer of tankless electric water heaters has anything like it. Self-Modulation Energy Technology Every Tempra® also has self-modulation. Self-modulation is sometimes confused with flow control, but it has more to do with the amount of energy used to heat the water. Self-modulation, sometimes call auto-modulation, ensures that only the least amount of energy is used at all times. Every Tempra® model continually monitors incoming water temperature, the flow rate of water through the heater, and the water temperature it produces. These sensors feed their readings into the unit’s proprietary microprocessor control which engages the heating elements in stages, as efficiently as possible, to achieve the water temperature set on the front panel, always using the least amount of energy necessary to heat the water. Constant Temperature Output While only Tempra® Plus has Advanced Flow Control™, every Tempra® has smart microprocessor technology and several temperature and flow sensors. This technology ensures a steady output temperature even if flow rates vary up or down, like when hot water is being used and an additional tap is opened or closed.  from other manufacturers don’t maintain a steady temperature if the flow varies. A Tempra® always does. Our exclusive Electronic Temperature Control allows setting the knob on the front cover to the water temperature desired and getting that temperature every time, and all the time, hot water is needed. All this electronic technology also means that Tempra® does not have any mechanical switches. It is completely silent while operating. Unlimited Supply of Hot Water A Stiebel Eltron Tempra® responds directly to your demand for hot water without interruption. Showers will always be hot, even if there are several taken in a row and they run long. A tank water heater may be able to deliver more water all at once, but once the tank starts to deplete things get cold and pretty quickly come to a standstill while waiting for the tank to recover.
