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
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
A:Â Make sure the front display is snapped together and turn the dial. If you are having issues, please call Technical Support at 1-800-582-8423 Ext 6 for assistance. Thank you

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.

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.

WIFE LOVES THE ENDLESS HOT WATER
The Stiebel Eltron Tempra 24 Plus has and is working according to the manufacture's claims. Although, the unit has only been in use for about a week, the installation was easy and the instruction manual very informative. Customer service representatives (Chris in Vermont) have had a very long relationship with Stiebel Eltron and are very knowledgeable of their products.
Three things to plan for during installation.
1) YEARLY FLUSHING.
2) HARD WATER FILTRATION.
3) WATER ISOLATION FOR FLUSHING AND FILTER CHANGES.

We decided to take a chance on an electric tankless...
We decided to take a chance on an electric tankless water heater to replace our failing propane water heater in our rural location. So far, the water heater is working well. We live in Northern Utah and the winter water temperature coming into the house is 46 degrees Fahrenheit. We can run two showers at the same time and with our low flow shower heads, the water heater can keep up. Just don't expect it to keep up with body sprayers, etc. in a situation like ours. At 118 degrees Fahrenheit, it takes a bit longer to fill up a bathtub than with our traditional tanked water heater, but that is not a big issue. We have a 200 amp service and the lights dim slightly when the water heater kicks on. There is no flickering, just a slight dimming. This appears to be expected since this is an older home that we had upgraded to 200 amp service. Our wiring, etc. was inspected due to the panel upgrade. It does save a lot of space in the utility room, which is nice. We have yet to check whether we will see any cost savings since it has only been installed for a couple of weeks. The propane water heater was 15+ years old and kicking on several times a day while making kettling sounds. This water heater is only used when we shower or wash dishes in the sink, and is dormant most of the time. With the increase in propane prices, the cost of propane rivals what we are paying for electricity when performing a Kw conversion.

Tempra 24 Plus in Northern Indiana
After learning that our 17 year old water heater began leaking while we were on vacation, I starting checking on having it replaced. Plumbers were saying 3-4 weeks to get to my job. I then decided to research tank less heaters. I settled on Stiebel Eltron after reading many reviews and feeling confident that I could install it myself.
The day following our arrival home, I started on the project. After 6-8 hours and three trips to the hardware we again had hot water. So far, we love it.
