Heat Pump vs Propane Heat in Montana
How Montana'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 Montana?
For many Montana 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. NorthWestern Energy Efficiency Plus (E+) rebates (estimated $450–$450) further reduce the net cost of switching.
Savings are not guaranteed. Verify your utility's electricity rate and current propane price before calculating payback.

| Factor | Propane heat | Heat pump |
|---|---|---|
| Fuel source | Propane (delivered or tank) | Electricity |
| Cost per BTU | High — among most expensive fuels | Lower with COP 2–3+ |
| Price volatility | High — global commodity | Lower — utility rate changes |
| Upfront cost | Low (replace furnace) | Higher, but NorthWestern Energy Efficiency Plus (E+) rebates reduce it |
| NorthWestern Energy Efficiency Plus (E+) rebate | Not applicable | $450–$450 |
| Also cools in summer? | No — separate AC needed | Yes — same system |
| Carbon footprint | Moderate-high | Lower with clean electricity |
| Tank ownership | Tank rental or ownership required | No tank needed |
What to calculate before switching from propane in Montana
Is a heat pump better than propane heat in Montana?
For most Montana propane users, a heat pump lowers annual heating costs. Propane is among the most expensive heating fuels per BTU, and a heat pump with COP 2–3+ delivers the same heat for significantly less. NorthWestern Energy Efficiency Plus (E+) rebates further reduce installation costs. Run the numbers with your actual rates.
What rebate does Montana offer for switching from propane?
Propane homes typically qualify for the highest heat pump rebate tiers through NorthWestern Energy Efficiency Plus (E+). Estimated range: $450–$450. Exact amounts depend on your utility and equipment. Verify with NorthWestern Energy Efficiency Plus (E+).
