Stiebel Eltron Tempra 20 Plus is designed to be virtually 100% efficient. Multiple heating elements inside the Tempra 20 Plus models activate as the water demand increases, thus providing maximum efficiency and complete comfort. The Advanced Flow Control system, available in Plus models only, monitors and adjusts the water flow to assure a constant temperature output.
The Tempra also 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.
