Product Overview

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 36 Plus provides hot water at a consistent temperature for 3-4 bathrooms in warm climates, or 2-3 bathrooms 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.
  • 300 Amp minimum total service to the residence, or an upgrade to this level, is necessary to install a Tempra 36 Plus as it has a maximum power draw of 150 Amps and requires 3 separate 50 Amp breakers with 3 separate runs of 8-gauge copper wiring
  • 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 240 Volt or 208 Volt electric service, and has a maximum output of 36,000 Watts at 240 Volts or 27,000 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
  • 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
  • Must be installed vertically, water fittings pointing down, with detachable connections such as braided flex connectors to allow periodic filter cleaning and flushing for scale, and an anti-scale filter is recommended if hard water is present
  • Professional installation recommended

Smart choice in the right application (Tempra Plus 15)
I installed this unit in August of 2019 (one year ago) and it is one of the best investments I've made since purchasing my condo. This unit replaced a 30 gallon electric tank water heater from the early 1990's which was not providing enough hot water for a bath or for two people to take showers. The tank had not been maintained so there was significant sediment which degraded the performance. The tank was installed in a cabinet near the breaker panel. The tank was a very tight fit--it's doubtful the anode was ever replaced as there was no headspace. After researching tankless units and consulting an electrician this model was the one recommended and for my application is the best solution. Our winter water temperature is 42 degrees F (southern Minnesota) and I had a limit to the electrical load so this unit is the largest I could install with those restrictions. From the photo you can see I am also limited to a small cabinet that used to hold the 30 gallon tank heater. This installation is in a condo with four fixtures that use hot water: a kitchen sink, lavatory sink, dishwasher, and shower/tub. This application has very short pipe runs--there is no recirculation pump for hot water or pipes inside exterior walls. The most difficult task was finding a plumber to install it--I called four reputable local ones and while their websites sold tankless units, the plumbers dispatched to estimate the job were all more keen to install a tank. I had to do a lot of research and speak with my local inspector to confirm that this could be installed; I found those with experience with tankless units (the inspector, electrician, and one plumber) knew a lot more about installation than those that just stuck to tank-type installations (the rest of the plumbers). Specific to the Stiebel Eltron Tempra 15 Plus--the "Plus" is necessary as it has a valve to regulate flow to maintain temperature and is unique to this brand. The installation and instruction booklet were well written, the unit has a clean appearance, and controls are simple to use. I do wish this had a remote display as it would be helpful to see the flow statistics from a better angle but I am limited to seeing the display where the unit is installed (inside a high cabinet). The interior construction is solid (a lot of copper) and straightforward--my electrician had no problem connecting it and it powered up right away. As for use, the water in a nearby faucet takes about 30-45 seconds to flow at the setpoint of 116F which is similar to what the tank unit performed at. Because the unit is tankless, there is no limit to the quantity of heated water. The unit is silent but in the winter if I'm filling the bathtub I can faintly hear the valve regulate the flow to maintain the outlet temperature of 116F I have the unit set to. The cabinet where the unit is installed has plenty of room to leave a flush kit in it and already had a drain (PVC pipe to vertical stack) from the former heater's TPR valve which the drain pan was plumbed onto. A big word of caution is that proper sizing a tankless unit is critical to your application and lifestyle--this unit is ideal for my application but in a house with several lavatories or a clothes washer it would be underpowered. I provided the electrician I hired with the spec sheet for this unit and he confirmed it would serve my needs--the vendor can also offer help in selecting the right unit. Tank-type units are more common in the U.S., often a little cheaper, and are simpler devices--since most homes come with one installed it's an easy choice to swap out one item that worked with a similar one--but in some applications a tankless unit is a smarter replacement. I don't have the measuring equipment in my home to see if this unit is saving me electricity over the 30-gallon tank unit--I haven't seen my electric bill go down significantly--this could be my usage habits as I no longer need to be concerned about running out of hot water.

We have had this installed for over a year now to provide hot water to one shower and two sinks (bathroom and kitchen). Great space saver compared to a lowboy 30gal hot water heater. It has worked flawlessly and the heat adjustment knob is awesome. Doesn’t take long to start having hot water. You do need a 50amp breaker with this unit in your panel. Thinking about replacing our 50gal tank with another one of these.
