Vermont’s long, cold winters and high oil dependency make heat pump savings especially dramatic. Modern cold-climate units maintain strong COP even below 0°F.
🔥 Size Your Heat Pump & See Your Annual Fuel Savings
Find the heat pump tonnage your home needs (heating + cooling load from area, climate, and insulation) and estimate annual fuel savings compared to your current Natural Gas, Propane, Heating Oil, or Electric Resistance system. Built on ACCA Manual J residential heating-load figures and real-world COP (Coefficient of Performance) values.
1. Home & climate parameters
These determine your home's heating load and the recommended heat pump tonnage. Sized using ACCA Manual J factors for an 8-ft ceiling home.
2. Your current heating fuel
Pick your current fuel and the rate your utility charges. The annual bill is optional: leave it blank to use the modeled estimate from your home size and climate above, or enter your real 12-month total to calibrate the estimate to your actual home. Defaults are US national averages.
3. Heat pump efficiency & electricity rate
Cold-climate heat pumps maintain high COP down to -15°C / 5°F and qualify for higher rebates (IRA 25C, Canada GREA). Standard inverter heat pumps are cheaper upfront but lose efficiency below 0°C / 32°F.

Heat Pump vs Heating Oil in Vermont: What You Could Save
At Vermont’s typical heating oil price of about $4.55/gallon and an electricity rate near 25¢/kWh, here’s how the annual heating cost compares for a representative Vermont home (~65 MMBTU/yr heating load, cold-climate heat pump at COP 3.8). Use the calculator above with your home size and real bill for an exact figure.
| Heating system | Estimated annual cost |
|---|---|
| Heating Oil furnace (~587 gallons/yr @ $4.55) | ~$2,669/yr |
| Cold-climate heat pump (~5,013 kWh/yr @ 25¢) | ~$1,248/yr |
| Estimated annual saving | ~$1,421/yr |
Figures are illustrative and depend on your home’s insulation, size, and actual usage — the interactive calculator personalizes all of this.
Cold-Climate Heat Pump Performance in Vermont
The old myth that “heat pumps don’t work in the cold” no longer holds. Modern cold-climate air-source heat pumps (ccASHPs) are rated to deliver their full heating output down to -13°F / -25°C and keep producing usable heat below that, thanks to variable-speed inverter compressors and enhanced-vapor-injection technology. In Vermont’s climate (Burlington and colder inland areas), the standard approach is to size the heat pump to carry 80–90% of the heating season and keep your existing heating oil system as automatic backup for the few deepest-cold nights — capturing nearly all the savings while keeping a safety margin.
Rebates & Incentives for Vermont Homeowners
Efficiency Vermont and Green Mountain Power both offer heat pump rebates (often $2,000+ combined), on top of the 30% federal 25C tax credit.
Because heat pumps also provide efficient air conditioning in summer, many Vermont homeowners effectively get whole-home cooling as a free bonus when they switch for heating savings.
Frequently Asked Questions — Vermont
Can heat pumps handle Vermont’s coldest nights? Vermont’s long heating season means high annual oil use, so savings are large — commonly $1,000–$1,700/yr switching from oil to a cold-climate heat pump.
How do heat pump operating costs compare to oil in VT? Yes — cold-climate heat pumps are specifically rated for Vermont’s sub-zero nights (-13°F and below). Efficiency Vermont recommends properly sized ccASHP units with existing heating kept as backup.
What Efficiency Vermont or federal incentives apply? Efficiency Vermont rebates plus Green Mountain Power (or your local utility) incentives stack with the federal credit — Vermont is one of the most heat-pump-friendly states for incentives.
