The previous generation of our most popular tankless water heater for whole house applications, the 2nd generation Stiebel Eltron Tempra 24 Plus electric tankless water heater is a powerful 24 KW heater and is an excellent choice for most whole house applications in the Northern U.S., Canada, and other regions where the incoming water temperature can drop below 45° F.

Like all Tempra Plus Series tankless water heaters, the Tempra 24 Plus features true microprocessor-controlled temperature regulation as well as a convenient digital temperature display and dial selector which allows you to set the desired output water temperature at any level between 86 and 140F (30 and 60C). It is one of the only tankless water heaters on the market that features a true thermostatic temperature control and full power-modulation based on both the incoming water temperature and the water flow rate. The Tempra 24 Plus will automatically adjust its power output to accommodate changes in the incoming water temperature and flow rate so it can precisely maintain the desired output temperature.

The Tempra 24 Plus also features Stiebel Eltron's exclusive dynamic Advanced Flow Control technology. This technology automatically adjusts the flow of water when the unit's sensors 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 and 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.) and where flow rates are not always predictable.

Simply stated, the Stiebel Eltron Tempra Plus Series electric tankless water heaters feature the most precise temperature control of any tankless water heater on the market today!

Do You Have Hard Water?
If your water hardness trends above 7 grains per gallon (GPG) or 120 mg/l (ppm), you should consider hard water treatment prior to your tankless water heater. If your hardness exceeds 12 GPG or 200 mg/l (ppm), hard water treatment is strongly recommended.

Hard water treatment helps maintain performance and efficiency, ensures optimal water flow and pressure, and protects your heater from pre-mature failure due to mineral build-up inside the heating module and other components.

* 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.

Please note: A minimum 200 AMP household electrical service is highly recommended and will likely be required to install this model. If you are unsure of your electrical capacity in your home, please consult your electrician or contact us for assistance before ordering.
