Bottom Line If budgets are tight, or you need a simple replacement for a standard electric water heater, the 40-gallon Rheem XE40M06ST45U1 looks like a good choice. Though not Energy Star qualified, it meets current regulations for energy efficiency. The warranty is just six years, but owner feedback is largely positive.
  • Meets efficiency regulations
