Michigan is one of the top propane-consuming states. Even at relatively moderate propane prices, a heat pump still wins on operating cost in most cases.
🔥 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 Propane in Michigan: What You Could Save
At Michigan’s typical propane price of about $2.25/gallon and an electricity rate near 22¢/kWh, here’s how the annual heating cost compares for a representative Michigan 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 |
|---|---|
| Propane furnace (~836 gallons/yr @ $2.25) | ~$1,880/yr |
| Cold-climate heat pump (~5,013 kWh/yr @ 22¢) | ~$1,103/yr |
| Estimated annual saving | ~$778/yr |

Cold-Climate Heat Pump Performance in Michigan
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 Michigan’s climate (Grand Rapids 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 propane system as automatic backup for the few deepest-cold nights — capturing nearly all the savings while keeping a safety margin.
Rebates & Incentives for Michigan Homeowners
Michigan utilities (Consumers Energy, DTE) offer heat pump rebates, and the federal 25C credit adds 30% (up to $2,000).
Because heat pumps also provide efficient air conditioning in summer, many Michigan homeowners effectively get whole-home cooling as a free bonus when they switch for heating savings.
Frequently Asked Questions — Michigan
Heat pump vs propane cost comparison Michigan Michigan has one of the largest propane-heating populations in the US. Rural propane users typically save $700–$1,300/yr switching to a cold-climate heat pump — propane’s volatile delivery pricing makes the savings especially attractive.
Do heat pumps work well in Michigan winters? Yes — cold-climate heat pumps are rated for Michigan winters down to -13°F; most homes keep the propane furnace as backup for the deepest cold while the heat pump carries the bulk of the season.
Available Michigan or utility rebates Consumers Energy and DTE offer utility rebates that stack with the 30% federal tax credit for qualifying cold-climate heat pumps.
