Product Description
"The Stiebel Eltron Tempra 15 Plus Tankless Water Heater features exclusive Advanced Flow Control German patented technology invented by Stiebel Eltron to automatically maintain water temperature for constant comfort. It’ll reduce flow slightly if hot water demand exceeds capacity to ensure that hot showers will never be interrupted. Tempra 15 Plus will typically use 15-20% less energy compared to conventional electric tank water heaters. Although, it’s possible to save significantly more energy depending on personal home usage habits. The difference is that conventional tank water heaters continually store hot water, and as a result, lose 15%-20% of the total energy consumed to the environment around them. This is called standby heat loss. Tank water heaters that use gas or oil are even less efficient, because they also lose heat through their vents to the outdoors. Our tankless water heaters do not need venting, and will not store hot water, waiting for you to use it. They operate on-demand to provide continuous and endless hot water when you need it, and not waste energy when you don’t. CERTIFICATIONS INCLUDE - ANSI/UL Std. 499, CSA Std. C22.2 No. 88, ISO 9001, WQA tested & certified against NSF/ANSI 372 for lead free compliance. TECHNICAL SPECIFICATIONS – Single Phase 50/60 Hz; Voltage: 240 V/208 V; Wattage: 14.4 KW/10.8 KW; Min. recommended household electric service 100 A; Amperage draw: 2 x 30 A 2 x 26 A; Number and min. recommended size of circuit breakers: 2 x 30 A (DP); Number of runs and min. recommended wire size (copper): 2 x 10/2 AWG; Max. temperature rises: 65 F/49 F at 1.50 GPM, 43 F/37 F at 2.25 GPM, 33 F/25 F at 3.00 GPM, Min. water flow to activate unit: 0.50 GPM/1.9l/min; Weight: 16.1 lb/7.3 kg; Nominal water volume: 0.26 gal/1l; Max. inlet water temperature: 131 F/55 C; Working pressure: 150 PSI/10 BAR; Tested to pressure: 300 PSI / 20 BAR; Water connections: 3/4"" NPT."

On to performance. I was skeptical at first, having been told by a few plumbers that on-demand technology wasn't up to par. But after having numerous serious incidents with multiple, professionally installed, tanked heaters, and after some research, I decided to give this one a shot. I have to say that not only am I impressed, but was also shocked and highly satisfied with this machines performance. It produces hot water, on demand, limited only by your water supply. I have mine set at 116 degrees, (extremely easy to read/adjust the display/temperature), and we take showers back to back to back to back here now, and it doesn't even break a sweat. Excellent product!
I've tested it by running two showers simultaneously for an extended period, and there was no interruption in the supply of hot water. The heater only uses the hot water necessary, which is not only eco-friendly but also cost-effective. The temperature control is precise, ensuring that you get the hot water you desire without any fuss. I appreciate the quality of this unit, and even the licensed plumber who installed it mentioned that it's one of the top brands in the market. This gave me confidence in my purchase decision. I had concerns about whether it would deliver hot water everywhere in my house, but those worries were unfounded. My two-bedroom, two-story home now enjoys consistent hot water supply throughout.
Of course, like any appliance, it's important to manage usage efficiently. Running multiple showers, a dishwasher, and a washing machine simultaneously might be a stretch for any water heater. However, with a bit of scheduling and planning, I've had no issues. I wash in the morning, run the dishwasher before bedtime, and take showers at various times throughout the day, ensuring they don't overlap. In conclusion, investing in the Stibel Electron Tempera 20 electric tankless water heater has been a wise decision for my household. It's efficient, reliable, and space-saving, making it a top-notch choice for anyone in need of a hot water solution. I also highly recommend having it professionally installed for peace of mind. It's a purchase that I'm truly satisfied with.

Read the review and decided to order this one
Replacement is fairly easy for a skilled DIYer. Unit is light and easy to install on the wall. Unfortunately the unit isn't set up for USA house stud layout as the mounting holes are 15" on center. I ran wood screws into studs on one side and used drywall anchors on the other. That was sufficient to securely mount .
Plumbing is straight forward. I replaced flex lines with PEX and insulated the hot sided. Though I don't think it's really needed.
Electrical can be a little complicated and you really need to take a look at your main or sub panel that powers the water heater. The old tank heater only needed one 220 volt 30 amp breaker circuit to run.
This unit needs 3 separate 220 40 amp circuits to run. This means you need 2 more 220 volt spaces in the breaker box to add those lines. If you don't. You'll need to install a sub box to run.
I'm not comfortable with electricity so I hired a professional electrician to properly wire. He had to run 2 new lines and drill through walls to get them from box to heater. It was a task I gladly paid for. That did cost $1200. Seemed a little high but that seems the going rate here in central Texas.
Usage. I first set it at the 119 degree setting. Temp was. Ok but I would have to run my show only with the hot side running. It was warm but not super hot. So I turned it up to 125 and definitely had to add cold water to the shower. I finally cranked the thermostat all the way up and can now shower using 50/50 hot to cold water for the perfect shower temp.
Since this is an on demand hot water heater expect a minute or so for the hot water to reach your tap if you haven't used In a while or first thing in the am.
After that.. it stays hit for ever and I haven't had it run cold.
Hope this helps. We are really happy to get this water heater.
Now time to install more shelves and closet rods so my wife stops using my area for her clothes. Lol
