(Additionally there is an $0.01/KWH rate reduction by Eversource if 90%+ of a home is heated by electricity (about $100 annual savings for households who use 10,000 KWH per year). Contact Eversource for more details.)

Air-Source Heat Pump Cost Comparisons

Installation: Air-source heat pumps cost less to install and maintain because of rebates/incentives and because it combines heating and cooling in one system.
Operation: For heating alone, operating heat pumps cost significantly less than oil or propane and even less than natural gas at 2022 prices.

Based on current utility and fuel prices as of stated date and average heating load of newest homes in Lexington (88.35 MMBtu).

Assumed fossil fuel efficiencies: gas 96%, propane 96%, oil 80%. Assumed heat pump COP: 3.2
