Is propane more expensive than natural gas for running a fireplace?
Per unit of heat, yes — propane nearly always costs more than natural gas, which is why fireplaces on the Asheville and Hendersonville mains are cheaper to run than the same units out in propane country. But a fireplace isn't a furnace: for evening fires and zone heating, the monthly difference is smaller in real dollars than the per-unit gap suggests.
Why the gap exists
Natural gas arrives by pipe from a regulated utility and gets metered as you use it. Propane gets trucked up a mountain road, stored in your tank, and priced by a delivery market that swings with the season and the supplier. That supply chain is the cost difference. Propane claws a little back on chemistry — it burns hotter per unit, so an LP appliance uses fewer units for the same warmth — but not enough to close the gap. Prices move too much for a fixed number to stay honest, which is why we talk in terms of the gap rather than quoting this winter's rate.
Most WNC homes don't get to choose
The fuel decision is usually made by your address. Natural-gas mains cover much of Asheville, Hendersonville, Fletcher, and Arden; out in Fairview, Candler, Brevard, and the cabins tucked up our mountain roads, propane is the gas option. If a main runs down your street and you're currently on propane, converting the fireplace is a straightforward licensed job worth pricing. If the main is half a mile away, propane's premium is simply the cost of having gas heat at elevation — and after Helene, most folks out here consider it money well spent.
The math that actually matters
Run the fireplace the way it's meant to be run and the fuel gap shrinks in practice: heat the room you're living in during the evening, let the rest of the house sit cooler, and you're burning gas in one room instead of heating the whole house during those hours. On either fuel, a sealed direct-vent unit converts far more of what you pay for into room heat than an open flame ever will. Want real numbers for your setup?
