The Best: Tankless Electric Water Heating

While every Stiebel Eltron model delivers superior performance, the Tempra® Plus series represents the industry’s high point of tankless water heater innovation. Manufactured by Stiebel Eltron, a pioneer and leader in tankless water heating technology for over 90 years, the Tempra® Plus line features our unique Advanced Flow Control function, which ensures that you’ll never be surprised by a cold shower. It also features two different temperature memory presets, making it easy to adjust for personalized needs. Thanks to these and other innovations, the Tempra® Plus ensures that you’ll enjoy endless hot water along with unrivaled efficiency.

Advanced Flow Control

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!

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.

Saves Energy and Reduces Your Electric Bills

Compared to a conventional electric tank water heater, a tankless electric water heater will typically use 15–20% less energy, although savings can be substantially higher depending on usage habits. Conventional electric tank water heaters continually store hot water and as a result, lose 15-20% of the total energy they consume to the environment around them. This is called standby heat loss. Gas or oil tank water heaters are even less efficient due to the fact that they also must be vented to the outdoors. A tankless electric water heater does not need to be vented and does not store full temperature hot water waiting for you to use it.
