Whole-Home Electrification in New Hampshire (2026)

Full home electrification in New Hampshire — heat pump, HPWH, solar, EV charger, induction, panel upgrade — costs $44,100-$62,500 before rebates. After New Hampshire rebates (up to $5,800), the net cost drops significantly. Annual savings of $4,000-$7,000 mean a 6-10 year payback.

Ducted Heat Pump: NHSaves: $1,000-$3,000/unit. Heat Pump Water Heater: NHSaves: $500-$800. 8 kW Solar Array: No state rebate (SB 303). Level 2 EV Charger: 30C: up to $1,000 (exp 6/30/26). The federal 25C and 25D credits expired Dec 31, 2025. Section 30C (EV charger, up to $1,000) expires June 30, 2026.

If your panel is 100 amps or less, you likely need an upgrade to 200A ($2,000-$4,500 in New Hampshire). A 200A panel can handle a heat pump + HPWH + EV charger. Smart panels like Span or Lumin can help manage loads without a full upgrade.

No. Section 25C (heat pumps, efficiency) and Section 25D (solar) both expired December 31, 2025. The only remaining federal credit is Section 30C for EV chargers — up to $1,000, expires June 30, 2026. Solar lease/PPA providers can claim Section 48 for projects starting before July 4, 2026.

New Hampshire homeowners switching from oil can save $4,000-$7,000 per year with full electrification. Your actual savings depend on home size, fuel type, insulation, and NH electric rates ($0.25/kWh average).

Start with your heating system — a heat pump provides the biggest savings and the biggest rebates in New Hampshire (NHSaves: $1,000-$3,000/unit). Add solar next to offset increased electric usage. Then tackle water heating, EV charging, and cooking as appliances age out.
