Stiebel Eltron Tempra 12B Electric Tankless Water Heater, 208/240 Volts

Unlimited supply of hot water: The Tempra™ continually heats water instantaneously as you require it - and only when you require it. The Tempra™ unit completely replaces a conventional tank heater with no disruption to your comfort and hot water needs.

Save energy and reduce your electric bill: Electric tank type water heaters are subject to stand-by losses which amount to 15 - 20% of the kWH used. In addition, water in a tank has to be heated hotter than necessary to account for these stand-by losses. Changing to a tankless system like the Tempra™ eliminates these problems and results in typical savings of at least 15 - 20% on the heating portion of your electric bill.

Sleek design saves space: The Tempra™ takes up considerably less space than conventional tank type water heaters and saves valuable living space.

Control temperature simply by setting a dial: Set the knob on the front cover and enjoy water temperatures between 86°F (30°C) and 125°F (52°C). Change the desired temperature at anytime. Advanced microprocessor technology ensures that the water temperature never deviates from the set point.

Better than gas: The Tempra™ has several advantages over a gas-type tankless water heater. Compared to many similar gas tankless models the Tempra™ is less expensive to purchase. Installation is also much simpler and cheaper since it is not necessary to vent a Tempra™ to the outside. The venting that a gas unit requires causes anywhere from a 10 - 20% efficiency reduction from heat escaping out the exhaust pipe. Furthermore, for every cubic foot of gas burned, two cubic feet of air have to be mixed in to create ideal combustion. In a cold climate, this hurts efficiency further. When a gas unit fires, it draws in air around it, heats the water, and then expels warm exhaust outside. Since no house is airtight, this suction action causes a drafting condition where cold air from the outside seeps back in through door cracks and other parts of the house that may not be airtight. By nature of the design, the Tempra™ is nearly 100% efficient; converting 100% of the electrical energy it consumes into heat. All that heat is then transferred to the water - none is lost to the outdoors.

Proven reliability: Stiebel Eltron has an enviable track record of engineering excellence and product quality. The three years parts warranty is unique in the industry. You can depend on the Tempra™ for many years to come.

Take the cover off: We have done our homework. As an international leader in the tankless electric water heating industry, Stiebel Eltron is proud to have pioneered this technology. The company's German engineering and manufacturing tradition of excellence means that you can depend on its performance for many years to come.

Seismic proof construction: The Tempra™ is a tankless water heater system, and is thereby not subject to seismic code. There is no need for preventative construction, as required when using a tank type water heater.

Superior, reliable performance: The Tempra™ has several temperature and flow sensors which feed their readings into the unit's proprietary microprocessor control. Heating elements are engaged in stages, achieving the temperature you desire. The Tempra™ continually monitors the water temperature it produces.

2/5 StarsBad controller design | Bought 2.5 yrs ago; installed in vacation cabin. Board component failed in 3rd year. Bad design on temperature adjust. Knob will not mesh with board component. Result is that I no longer can adjust temperature. Company admits to bad design. Fixed problem in newer model. Be sure not to buy old model.
Recommended? No.
5/5 StarsA great product | Several of the owners at our condo association in Cabo San Lucas use the Tempra 12 to heat the water for our condos. We have very limited electrical amps, so it works very well. So far, I know of 7 owners currently using this model.
Recommended? Yes.

I apologize but I am unable to answer this as there are many factors to be considered that I am unaware of, one being what item will best be applied to meet code for your application. I can suggest contacting a local professional for what item will best be suited to meet your needs.

Q:Are these units CSA approved, and can they be installed into a mobile home? Derek | Wednesday, November 7, 2012

These units are not CSA approved but the are ETL approved which is a certification for use in Canada as well as the US. This can be used in a mobile home, depending on your application as it draws 50amps. This unit can be hooked up to 208/240 volts.

Q:Looking to install this (Stiebel 12B electirc) heater in a seasonal dwelling. I want to make absolutley sure that this heater will easily drain completely so I do not have to worry about a freezing problem. Can you confirm? Thanks rbRobert Bruce | Thursday, October 11, 2012

This unit can be installed in seasonal dwellings, the manufacturer just recommends the heater be completely drained if the temperature is going to be less the 36 degrees in order to protect the unit and not void the warranty.
