You don’t need any interior design expert to tell that Stiebel Eltron Tempra 29 Plus is one of the best looking indoor tankless water heaters. With its colorful control knob and digital display, its minimalist beauty is certainly timeless and future proof. On to the warranty, you’re backed with one that is valid for 3 years. However, you must agree that all the installation is carried out by licensed personnel. It’s not an issue we believe considering the plumbing and wiring works aren’t necessarily a straightforward project.

As for the operation, Stiebel Eltron Tempra 29 Plus is devised to be a whole house water heater, which is rather unusual for electric model. There is no disclosed information about how many gallons per minute it can supply but given the company’s own Advanced Flow Control technology, we guess the claim is true after all. For your information, the said technology enables the unit to keep the set temperature constant no matter if the demand is high. This is done by adjusting the flow of the water. So, when many faucets open simultaneously, you will probably find a slight drop on the water flow rate. Good thing is, you won’t get any unpleasant cold water sandwich effect.


As we told earlier, the warranty for Stiebel Eltron Tempra 29 Plus is valid only if you hire licensed personnel to take care of the whole installation. That would translate to some extra cost. Also, you have to be ready to shell out more in the beginning because all electrical components like breakers, wires, and electrical box aren’t included. In addition, the heater is optimized for residents with 200 AMP household electrical service; any lower than that, you will very likely run into trouble.


For an electric heater, this model is definitely not a cheap one. As a positive note, however, it can handle multiple open faucets without showing any slightest drop on the output water temperature. All in all, Stiebel Eltron Tempra 29 Plus is highly recommended for anyone looking for an electric tankless heater that works flawlessly.
