Heat Pumps in Dover: What Homeowners Should Know
Dover has roughly 7,789 heating degree days a year, a very cold climate that determines how hard a heat pump works each winter. A typical 2,000 sq ft home here needs about a 5-ton system, installed for around $17,000 — or about $15,500 after the local rebate of up to $1,500.
Swapping electric-resistance heat for a heat pump in Dover cuts heating costs from about $6,025 to $2,739 a year — a saving of roughly $3,286 annually at the local electricity rate of $0.220/kWh, and an estimated $47,449 over 15 years. Savings are even larger if you currently heat with propane or oil. Note: the federal 25C heat-pump tax credit expired at the end of 2025, but New Hampshire rebates and the income-qualified HEEHRA program (up to $8,000) can still bring the cost down.
