Tempra 29 Plus Adv Flow Control and Self-Modulating 28.8 kW 5.66 GPM Residential Electric Tankless Water Heater

Overview

Powerful output, compact design, remarkable energy-saving features. Our whole house electric tankless water heaters perform with the highest standards for comfort and reliability. Tempra Plus models feature Advanced Flow Control, patented in Germany and exclusive to Stiebel Eltron tankless heaters. If hot water demand exceeds working capacity, Advanced Flow Control automatically maintains consistent temperatures by slightly reducing flow. Intelligent self-modulating technology continually ensures the least amount of energy is used to heat the water. A Tempra 29 Plus provides hot water at a consistent temperature for up to 3 bathrooms in warm climates, or 2-3 bathroom in cool climates. See sizing to determine which model is best for you. Stiebel Eltron invented tankless electric water heating technology more than 90 years ago, and is still the industry pioneer and world leader.

Questions & Answers

How does this work with low flow sinks and shower heads at minimum flow for activation at 0.77 GPM?

Anyone have experience with this unit not turning on with low flow sinks when you’re just trying to wash your hands or face? Or with a very efficient shower head? I’m worried that the hot water flow won’t be high enough to even engage the unit. Other units I’ve seen start at 0.29 GPM.
Asked by: RenoT
The unit heats water as soon as I open the sink faucet.. the minimum flow rate should not be a problem.. be more concerned with the maximum flow rate at a real showering temperature... they list flow rates at a minimally warm temp and at a setting of 130 I get 1.8-2.0 and that’s sufficient for 1 shower as normal, open anything else and flow rate drops the pressure.

With Advance Flow Control, does this mean it would possibly scale back flow that it goes below activation gpm flow?

Asked by: Mike
No, it will not effect the activation point.

Since I do not yet have three 40 amp circuits available, can I just hook up one of the heating elements in the interim and it will still work?
Asked by: Cheers
Unfortunately not. You need all 3 hooked up for this unit to work
