Stiebel Eltron Tempra 20 Plus Electric Tankless Water Heater Review
The Stiebel Eltron Tempra 20 Plus is a 20.7 kW whole-house electric tankless, smaller than the popular Tempra 24 Plus and Tempra 29 Plus. Sized for 1-bath warm-climate homes or as a small whole-house alternative in mild climates.
Specs: 20.7 kW, two 40-amp double-pole breakers, 86A continuous draw at 240V. Capacity: 2.4 GPM at a 60°F rise or 3.7 GPM at a 40°F rise. Stainless steel heat exchanger. 7-year warranty on heat exchanger.
Right answer for: 1-bath warm-climate primary residence, 200A service homes with single-bathroom demand. Premium German engineering with PID-based temperature control — quieter and smoother modulation than EcoSmart equivalents.
About $950 unit, $2,000 installed. Right buyer: 1-bath home wanting premium European engineering over volume electric tankless brands.
