Heat Pumps in Nashua: What Homeowners Should Know

Nashua has roughly 7,990 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 Nashua cuts heating costs from about $5,871 to $2,669 a year — a saving of roughly $3,203 annually at the local electricity rate of $0.209/kWh, and an estimated $45,845 over 15 years. Savings are even larger if you currently heat with propane or oil.
