Both are heat pump water heaters. The RE2H65T is more efficient (UEF 3.64 vs 3.34). The NHP65 saves $67/year to operate. All figures from published specs and EIA energy prices. UEF measures lab efficiency under DOE test conditions. Annual cost uses that rating plus national average energy prices. Different draw patterns, local rates, and standby losses can cause the rankings to diverge.
