How to Save on Water Heater Replacement Cost (2026)
The 30% federal tax credit for heat pump water heaters expired December 31, 2025. But state rebates, utility programs, competitive quotes, and smart timing can still save homeowners $800-$2,500 on a water heater replacement. Here is how to stack every available discount.
The Federal Heat Pump Tax Credit Has Ended
The 25C Energy Efficient Home Improvement Credit gave a 30% federal tax credit (up to $2,000) for qualifying heat pump water heaters. The One Big Beautiful Bill Act ended it: only equipment placed in service on or before December 31, 2025 qualifies. Water heaters installed in 2026 do not get any federal tax credit. If you installed a qualifying heat pump in 2025, you can still claim it on IRS Form 5695 with your 2025 return. State and utility rebates below are separate programs and remain available.

Real Savings Example: Stacking All Incentives
A homeowner in Massachusetts replaces a 12-year-old electric tank with a Rheem ProTerra heat pump water heater:
Until December 31, 2025 the 30% federal tax credit would have cut a further $960 off this unit, but it has expired. On top of the rebates above, the heat pump still saves about $320/yr versus the old electric tank, roughly $3,200 over its 13-15 year life.
