Expert Review
The Stiebel Eltron Tempra 36 Trend is the electric tankless we recommend when homeowners want whole-house tankless without gas. At 36kW, it delivers up to 7.5 GPM even with Long Island's cold inlet temperatures — far more than any EcoSmart or Rheem electric tankless. The advanced flow control automatically adjusts flow to maintain set temperature, preventing the dreaded cold-water blast. German engineering shows in the build quality. The catch: it requires 150 amps of dedicated electrical service, which may mean a panel upgrade.
