Costs at U.S. average electricity rate of 17.24¢/kWh (EIA, 2025-12).
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 700+ cubic feet)
- Heat pumps are taller: expect 61-74 inches vs 58-59 inches for electric tanks
