Heat Pump vs. Propane Heat in Southern Indiana: The Real Math

Why propane loses on operating cost

Propane is the region's most expensive common heat. Every winter, homes across Jefferson, Jennings, Ripley, Trimble, and Henry counties pre-buy propane at prices that make electric resistance look competitive — and a modern heat pump delivers two to three units of heat per unit of electricity, which propane combustion can't approach.

For most propane-heated homes we quote, the heat pump's operating savings cover a meaningful share of the equipment payment. That's not a sales line; it's arithmetic we run on your actual fuel bills before recommending anything.

But do they work in our winters?

The 1995 objection doesn't survive 2020s equipment. Cold-climate heat pumps hold their rated output near 5°F — colder than almost every night the Ohio Valley sees — and keep producing below that. The handful of brutal nights each winter are what correctly sized backup heat, or a dual-fuel configuration, exist for.

When dual-fuel wins

If you already own a healthy gas or propane furnace, dual-fuel pairs it with a heat pump and switches automatically at an engineered balance point — the heat pump carries the 90% of the season it handles cheaply, the furnace takes the coldest snaps. The balance point should be calculated from your fuel prices and the equipment's capacity curve, not left on a factory default that switches over fifteen degrees too early.
