Costs at U.S. average electricity rate of 17.45¢/kWh (EIA, 2026-01).

Installation differences

  • Both types use 240V electrical service
  • Heat pumps typically need a 30A breaker vs 25A for electric tanks
  • Heat pumps require a condensate drain line
  • Heat pumps need adequate air volume around the unit (typically 750+ cubic feet)
  • Heat pumps are taller: expect 61-74 inches vs 58-59 inches for electric tanks

Based on published specs of models compared above. Verify requirements with manufacturer specs and local codes.
