About This Product

Powerful output, compact design, remarkable energy-saving features. Our whole house electric tankless water heaters perform with the highest standards for comfort and reliability. Tempra Plus models feature Advanced Flow Control, patented in Germany and exclusive to Stiebel Eltron tankless heaters. If hot water demand exceeds working capacity, Advanced Flow Control automatically maintains consistent temperatures by slightly reducing flow. Intelligent self-modulating technology continually ensures the least amount of energy is used to heat the water. A Tempra 24 Plus provides hot water at a consistent temperature for up to 2 bathrooms in warm climates, or 1-2 bathroom in cool climates. See sizing to determine which model is best for you. Stiebel Eltron invented tankless electric water heating technology more than 90 years ago, and is still the industry pioneer and world leader. Our engineering and manufacturing tradition of excellence means you can depend on the performance and reliability of our products.

Highlights

  • Tempra tankless electric water heaters must be correctly sized and you should consult the sizing guide to determine the correct model for you
  • This Tempra Plus model has German patented Advanced Flow Control that automatically reduces output flow to maintain temperature if demand temporarily exceeds capacity
  • Requires a minimum of 150 Amp total service to the residence, with 2 separate dedicated 50 Amp DP breakers and 2 separate runs of 8-gauge copper wiring for the Tempra 24 Plus itself
  • Requires 240 Volt or 208 Volt electric service, and has a maximum output of 24,000 Watts at 240 Volts or 18,000 Watts at 208 Volts
  • Supplies endless hot water at a constant and steady temperature from 68 to 140°F (20-60°C) that can be set on the front panel digital display
  • Flow rate you achieve from this or any tankless water heater depends on how powerful the unit is and the temperature difference between the incoming cold water and the hot water being delivered

Q:My broken electric hot water heater serves 2 bathroom sinks, 1 tub, 1 shower and 1 powder room sink. What size tankless unit of your product would fit this scenario, and what would the wiring requirement be?
by|Jul 18, 2024
1 Answer
Answer This Question

A:  Really depends where you are located (cold water incoming temperature) and what kind of flow rate each fixture has. IF your electrical panel can support a Tempra 36 Plus then yes, install this unit. More likely the Tempra 29 Plus will be the unit to look at. In either case, call Tech Support to discuss which unit you should install. Phone number 1-800-582-8423 Ext 6 Thank you!

        Q:Would this unit run 2 showers simultaneously? I have a water input flow rate of 12gpm.
        by|Jun 26, 2024
        2 Answers
        Answer This Question

        A:  This unit, depending on the incoming water temperature, could run 2 showers at a time. I would confirm the GPM's coming out of each shower (typically about 1.5 to 2 GPM per shower head) IF you needed 12 GPM, no water heater would do that. If you have any further questions, please feel free to call Technical Support at 1-800-582-8423 Ext 6 Thank you!

        by|Jun 27, 2024

          A:  It may handle two showers simultaneously depending on the flow rate of the shower heads and if you are in a warm weather climate. If your showers are putting out the 12 gpm, then no it cannot handle this. You may want to call the office at 800-582-8423 ext 6 and speak to representative to ensure this is sized properly.

              Better Than Expected
              Just had this installed and am very happy with this purchase. With the temp set to 130, the water comes out nice and hot! In my last home I installed an ECOsense and with the temp set to 140 I only had warm water. Same with the hot water tank in my new house! This was a great buy!

                This tankless water heater really performed. Primarily purchased to replace an older tank water heater. The primary objective was to be able to fill a huge jacuzzi tub with hot water. The old 40 gallon tanked water heater could not accomplish this task. The Stiebel Elton did it beyond expectations. Love the flow control of the plus system.

                So far so good, small foot print. Initial installation can cost more due to additional wiring.

                Very pleased with this so far
                PLAN AHEAD! Got one to free up space in our 1100 sq ft condo. The old tank unit was under the stairs. Condo is electric only, no gas, so limited selection. Also required 2 30 amp circuits. Changed out nearby washer/dryer for an all-in-one that runs of 110 and were able to move that circuit over. Some units require 40 amp circuits. Takes about 45 seconds for kitchen sink water to heat, 90 secs upstairs shower, limited pressure elsewhere when shower is running, but no biggie.

                  Pretty good
                  I installed this together with a soft water system. All worked well and plumber had no issues. We have 3 full bathrooms. Set at 120, water runs pretty hot. No issues with water pressure either. If you don't mind waiting a bit for hot water this tank does the job. Worst here is about 1 minute and only in 1 bathroom.

                  Tankless water heater
                  Selected this model as an upgrade from our last one (also a Stiebel), we had home depot install it, and we couldn't be happier.

                  Great investment
                  Love this product. Never run out of hot water. Save on water bill with no tank to fill. Save on electricity bill. Performs excellent.
