Model # Tempra 12 Plus Store SKU # 1000782305

Stiebel Eltron has been a world leader in advanced water heating technology for almost 90 years. Our engineering excellence and high-quality manufacturing results in products fulfilling the highest expectations of performance & reliability. Tempra Series whole house tankless electric water heaters are 99% efficient and never waste energy storing hot water, but endlessly deliver it as needed. Tempras need no venting. Installation can be close to draw off points, making the wait for hot water as short as possible & maximizing energy savings. Tempras are sized based on the number of bathrooms. Tempras supply water at a constant temperature from 86 to 140 degrees F that is settable on the front panel. We recommend setting the actual highest temperature you use, typically 107 degrees for a shower. Tempra Plus models incorporate Advanced Flow Control that automatically reduces flow to deliver water at the set point if demand exceeds capacity. Regular Tempra models do not have this feature.

Rated 4 out of 5 by from Makes hot water Does what I expected, I have 100amp service so was worried about overloading but I just use appliances accordingly. 950 sqft house with 1.5 bathrooms and two people. Only downside was the unexpected $160 wire I needed to buy (6/2) and the breaker needed takes up 4 spots in the panel. Install was easy enough though. Only been in use for 3-4 weeks so can’t speak of reliability.

In terms of build quality and silent, efficient operation, this may be the best tankless water heater on the market (IMHO). Purchased a Tempra 12 Plus to replace a six-month old product that had shorted out a high-voltage relay on its circuit board... with a bang and a spectacular fireball. The "old" WH (from a different manufacturer) had always made clicking sounds when the heater kicked in and out, which was a little annoying. Was just glad it did not set the house on fire. (Side note: after purchasing that WH, the manufacturer sold out to a larger player in the tankless market, and they have temporarily pulled that model from production for modifications.) Back to the Stiebel-Eltron, operation is completely silent in operation. When the unit is heating, a small Power LED between the temp-setting display and the temp adjustment knob lights up. The LED temp readout only displays the unit's current temperature setting, not the actual outlet temperature. I have temp gauges at the inlet and outlet, and the LED reading always matches the outlet reading. Another nice feature is the T-rad jumper on the circuit board. It limits the maximum outlet temp to 109 degrees F (to avoid scalding temperatures at the faucet). I set the T-rad jumper, then set the temp adjustment to 107. Nice and hot, with no risk of scalding. My Tempra takes its input water from a 60-gallon solar batch heater. When a hot water valve is turned on, the LED will come on for a few seconds, until the heated water from the solar heater reaches the unit. Operation is smooth and seamless. I like the build quality of the Tempra over all of the other products that were researched. Fine German craftsmanship from the company that has been in the water heating business longer than all of its competitors, which in itself speaks for the reliability that I expect to see from it. The Tempra 12 Plus may cost more than competing products, but, as always, you get what you pay for. Money well spent.

Rated 3 out of 5 by from Great Heater, but poor value This water heater is technically awesome. Easy electrical installation with 6 gauge wire and a single 60A-240V breaker. Plumbing install is a breeze. Water Temperature is consistent with no water pressure issues when being used with a standard modern low flow shower head. But... My rating is brought down due to the price. While the flow control feature is nice, I don't feel that this feature and a larger box with a digital display are worth almost $300 more than the same heating capabilities of their DHC-E 12

Rated 4 out of 5 by from Tankless water heater Bought this summer. Installed and working fine. Installed in cabin with two sinks,washing machine and shower. This produces enough hot water. Installed with 2wire(2 power wires 1 ground) gauge 6 wire and double 50 amp breaker on 100 amp panel, these are necessary. Not well marked in instructions.

Worth every penny. I will only recommend this brand, to anyone who asks me. The temperature is consistent. Within the limitations of the product, you would not even notice that you had converted from a tank. Except that you will never run out of hot water. I went with cheaper brands before and even though the manufacturers refunded my money, I wasted hundreds of dollars on electrical and plumbing instead of biting the bullet and paying for the superior product the first time. A+
