Stiebel Eltron Tempra Plus 29 Key Specs
29kW
This power rating determines the maximum flow rate of hot water the unit can deliver. A 29kW model is designed for whole-house applications or multiple simultaneous fixtures. You should compare this capacity with lower-kilowatt models if you need higher flow rates during peak usage times. It ensures consistent temperature rise for demanding household needs.
19 inches wide
This width indicates the horizontal space the unit occupies on your wall. It is relatively narrow, allowing for installation in tight utility spaces or closets.

9 inches high
This height makes the unit vertically compact, fitting easily under cabinets or in low-ceiling areas. It is shorter than many traditional water heaters. You can compare this dimension with taller units to maximize vertical storage space above or below the heater. This slim profile is ideal for installations where vertical clearance is limited or restricted.
17.4 pounds
