Stiebel Eltron Tempra Series Electric Tankless Water Heater Models

Electric Tankless Water Heater - Model Selector The Stiebel Eltron Tempra Series of electric tankless water heaters provide an endless supply of hot water on demand to your whole house while saving you up to 50% off your water heating cost!

The Stiebel Eltron Tempra and Tempra Plus electric tankless water heaters uses a sophisticated thermostatic temperature control that constantly monitors the incoming water flow water and temperature to modulate power to the heating elements to maintain a precise, user-set temperature. Convenient controls allow you to set the output temperature to your desired level (between 86 and 140F (30 to 50C) [Note, maximum temperature setting on some models is 125F (52C)]. Most competitor's tankless water heaters are not able to compensate for changes in water flow rate and temperature, making their units fluctuate when simultaneous water demands are run, when well pump pressures change, etc. This is because their systems operate either on a "full on / full off" basis or they have relatively crude power modulation technology.

Tempra Plus series models take temperature control to another level, offering the industry's only Advanced Flow Control technology. This technology automatically adjusts the flow of water when the unit's sensor's detect that the flow demand is exceeding the heater's capacity. This feature is particularly useful in cold climates and other applications where the electrical service size does not permit the installation of a larger model where it may be desirable to handle occasional high flow demands. It is also desirable where high output temperatures are required for temperature-critical applications (commercial dishwashers, etc.) where flow rates are not always predictable.

Stiebel Eltron manufactures Tempra and Tempra Plus Series models, for almost every conceivable water heating application. All Tempra Series models are essentially the same except for the maximum heating power. Similarly, all Tempra Plus Series models are essentially the same at each other except for their power rating. They differ only in the quantity and power rating of the heating modules.

The following chart highlights the key differences between the current Tempra Series models....

Tempra Plus Series Tempra Series

The most appropriate model for each application is generally a function of your incoming water temperature (where you live) and your water usage needs and what features you desire. Please use our model selector or use the technical specifications below to assist you in selecting the best tankless water heater model for your application. Stiebel Eltron tankless water heaters are designed to completely replace your conventional hot water tank.

* Breaker size and wire gauge must meet all applicable local, state, provincial, and national electrical codes for your area - these are only guidelines that will apply to most installations. Some codes require use of electrical sub-panel for installation, especially when heater is not mounted within line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load. Please consult your electrician for more details.

** The maximum output temperature is a function of incoming water temperature and water flow rate. For residential applications, all units are factory pre-set to permit a temperature setting from 86F (30C) to either 125F or 140F (52 to 60C). The temperature setting can be easily adjusted using the adjustment dial on the front of the heater.

Important Pre-Purchase Information

Prior to purchasing your Stiebel Eltron Tankless Water Heater, it is important that you ensure that your home has sufficient electrical capacity for the desired model, or that you have budgeted for any upgrades that might be necessary. Please note that all electrical tankless water heaters, regardless of the manufacturer's claim, are restricted in reality to approximately 3 gallons per minute of flow at any given time in cold winter climates. This is generally more than enough for residential applications, however, certain simultaneous water usages in the home at single or multiple outlets may exceed this capacity. Please bear this in mind when selecting a model or system for your home. See the chart on our Tankless Water Heater Model Selector page for maximum flow capabilities based on your climate and model selected.

Electrical Requirements for Stiebel Eltron Tempra Series Tankless Water Heaters:

Before purchasing a Stiebel Entron, or any other electric tankless water heater, please ensure that your home has sufficient electrical capacity for your desired model, or that you have taken note of any upgrades that may be required.

Some codes require use of electrical sub-panel for installation, especially when heater is not mounted within line-of-sight of the main electrical panel. Wiring should be sized to maintain a voltage drop of less than 3% under load. Please consult your electrician for more details.

The above specifications are only guidelines. If your home is already equipped with a large number of electrical appliances, you may require a larger electrical service than the one recommended above. Please consult an electrician before placing an order.

If your home does not have the minimum household electrical service as specified for your desired model, you can still purchase a Stiebel Eltron tankless water heater, however, upgrades to your electrical service will likely be required. It is recommended that you consult your certified electrician for a quote, prior to purchasing.

Please be aware that uninstalled units returned due to a home that has inadequate electrical service may subject to a re-stocking fee. Please see our POLICIES page for more details.
