Combine NHSaves heat pump rebate ($1,250) with New Hampshire solar incentives ($0) for up to $3,750 off.
Heat pumps provide both heating and cooling. Combined with solar, your home stays comfortable all year at near-zero energy cost.
Bundling solar panels with a heat pump is the fastest way for Durham homeowners to reach near-zero energy costs. A 10 kW solar system generates approximately 12,000 kWh per year—enough to power your entire home plus the additional electricity a heat pump needs to replace your oil & propane heating system. At Eversource Energy (NH)’s rate of $0.20/kWh, this eliminates roughly $2,340 in annual electric costs while the heat pump saves an additional $1,950 per year versus oil & propane. Combined, that’s $4,290 in annual savings.
Both the federal residential solar tax credit (Section 25D) and the heat pump tax credit (Section 25C) expired December 31, 2025 under OBBBA. However, New Hampshire state and utility incentives remain strong. The NHSaves heat pump rebate covers up to $1,250. Eversource Energy (NH) adds a $2,500 utility rebate. Income-qualified households may also receive HEAR rebates of up to $8,000. Combined, these incentives total up to $3,750.
NuWatt Energy designs integrated solar + heat pump systems specifically for Durham homes. We size the solar array to account for the heat pump’s electricity consumption, ensuring maximum offset from day one. Our team handles everything from system design through Eversource Energy (NH) interconnection and all rebate applications—one contractor, one project, one point of contact.
