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!

* 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.
Stiebel Eltron Tempra 24 Plus (White) Reviews
Great improvement over a hot water heater. Nice to have all the hot water I want and save on bills. More space in garage.
2 Years Running Strong at the Farm
Don't hesitate to consider going tankless or if your wondering if gas is cheaper etc. I purchased this unit 2 years ago for my farm a to replace a 26 year old water tank. The price per month for electricity is lower and the water hot water is clean because it doesn't sit in the water tank! I installed this with 2 double pole 60 amp breakers and 6/2 wire.. Simple.
SO much better
Purchased this unit to replace another tankless water heater and the Tempra 24 Plus is SO much better. Installation was easy and the flow control on this unit makes all the difference. You can't go wrong with this unit as we have had great success for the 1.5 years we have been using it.
Tankless hotwater heater
Outstanding and allows us to use two or more hot water outlets at the same time. Two showers and a dishwasher all at the same time and everyone gets hot water

Provides unlimited hot water for the house. It runs both showers for 30 plus min with no problem.
