The Best: Tankless Electric Water Heating

Tempra® is manufactured by Stiebel Eltron, a pioneer and leader in tankless water heating technology for over 90 years. Advanced technology, impressive energy-saving performance, and a compact design are only a few of the reasons to consider a Tempra® tankless water heater.

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.

In addition, installing low-flow showerheads and flow-reducing sink aerators, coupled with optimising your personal water usage habits can result in savings much greater than the typical 15-20% stated.

Tempra Advanced Flow Control

Tempra Advanced Flow Control was invented by Stiebel Eltron. No other manufacturer of tankless electric water heaters has anything like it.

When demand gets too great, other manufacturers get cold. Tempra Plus reduces flow to keep the temp hot.

Tempra Advanced Flow Control Module Close-up

Tempra Advanced Flow Control is exclusive to our Tempra® Plus models. If the demand asked of a Tempra® Plus is greater than the unit can handle, Tempra Advanced Flow Control works by slightly reducing the flow of water. Unlike other manunfacturers that deliver colder water than the set point, a Tempra® Plus automatically delivers slightly less water, but at the correct temperature. No more cold water suprises!

Constant Temperature Output

While only Tempra® Plus has Advanced Flow Control, every Tempra® and Tempra® Plus has smart microprocessor technology that ensures a steady output temperature even if flow rates vary up or down. Tankless electric water heaters from other manufacturers don’t maintain a steady temperature if the incoming flow varies. A Tempra® always does. Our exclusive Electronic Temperature Control allows setting the knob on the front cover to the water temperature needed and getting that temperature every time a hot water tap is opened.

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.

Easy to Size for Every Home - Find the Right Size

Sizing Guide Map

Hot water needs vary from home to home. Stiebel Eltron’s full line of Tempra® tankless water heaters offers a variety of choices to meet all requirements.

The correct size Tempra® largely depends on the temperature of the ground water and the number of bathrooms in a house. It’s easy to determine which Tempra® model best satisfies a household’s needs. Click the map for the complete Sizing Guide.

If there are high flow showers, or another out-of-the-ordinary situation, please call or email for advice. Stiebel Eltron service representatives provide assistance and make recommendations on sizing, or any other matter concerning our water heaters, to both homeowners and professional installers.

Sleek Design Saves Space and Reduces Waste

By installing a Stiebel Eltron Tempra®, you will free up several square feet of floor space that your bulky hot water tank is now using. Also, due to their small size, they use vastly less raw material to manufacture compared to a tank. Disposal of a tankless has a much lower environmental impact, and all major components are recyclable.

Easy to Install

A Stiebel Eltron Tempra® doesn't cost any more to purchase than a conventional tank water heater. Installation is often cheaper. Because storing water at high temperatures shortens the lifespan of a conventional tank water heater, Stiebel Eltron tankless units also have a longer service life, saving you money by reducing how often replacement is necessary.

Large and bulky hot water tanks are usually placed in a basement or utility room. Because the tank may not be close to where hot water is used, there is a wait for hot water. A Tempra’s compact design can be installed close to the hot water taps. When this can be done, in new construction for instance, the wait for hot water becomes as short as possible. Even in a retrofit, where it might not be possible to place a Tempra® closer to the hot water draw-off points, its considerably smaller size has many advantages.

Seismic Proof Construction

Because a Tempra® is a tankless water heating system, it is not subject to seismic building code. There is no need for the preventative construction required with a tank water heater.

Maximum Output Temperature Limit

Tempra® Plus tankless water heaters can be set to limit the maximum hot water temperature to 109°F. This can be important in some installations to prevent the possibility of scalding.

Superior, Reliable & Quiet Performance

Comfort Through Technology

Each Tempra® has several temperature and flow sensors that feed their readings into the unit’s proprietary microprocessor control. A Tempra® continually monitors incoming water temperature and the water temperature it produces. It engages its heating elements in stages to achieve the water temperature you desire as efficiently as possible.

A Tempra® also does not have any mechanical switches. It is completely silent while operating.
