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 20 Plus provides hot water at a consistent temperature for 1-2 bathrooms in warm climates, or 1 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 125 Amp total service to the residence, with 2 separate dedicated 40 Amp DP breakers and 2 separate runs of 8-gauge copper wiring for the Tempra 20 Plus itself
  • Requires 240 Volt or 208 Volt electric service, and has a maximum output of 19,200 Watts at 240 Volts or 14,400 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
  • 99% efficient and typically result in savings of 15-20% in comparison with electric tank water heaters
  • Smart microprocessor technology unique to Tempra water heaters delivers steady water temperature even when flow rate vary as taps are adjusted

          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.

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

              Best decision ever.
              We replaced a traditional hot water heater with the Stiebel. We were worried the old heater would burst and flood our house. We love this tankless heater. No noise. You would never know it is in the hall closet. Hot water on demand should be the only option for houses. I love it.
