Heat Pump vs Propane Heat in South Carolina
How South Carolina's rebates, electricity rates, and propane costs compare — and what to calculate before switching from propane to a heat pump.
Is a heat pump better than propane heat in South Carolina?
For many South Carolina propane users, switching to a heat pump meaningfully reduces annual heating costs. Propane is among the most expensive heating fuels per BTU. A heat pump with a COP of 2–3+ delivers the same heat for roughly half the operating cost or less, depending on electricity rates. Santee Cooper EmpowerHome rebates (estimated $300–$700) further reduce the net cost of switching.
Savings are not guaranteed. Verify your utility's electricity rate and current propane price before calculating payback.
