What's the difference between a natural gas and a propane fireplace?
The fireplace itself is nearly identical — the real difference is the fuel behind it. Natural gas arrives through an underground utility main; propane is stored in a tank on your property and burns at higher pressure through different orifices inside the unit. Most fireplaces we carry come in both versions or convert with a factory kit, so the practical question is which fuel your address actually has.
Same firebox, different plumbing
Inside the appliance, natural gas (NG) and propane (LP) versions differ in small but critical parts: orifice sizes, valve settings, and operating pressure. Propane carries more energy per cubic foot, so it meters through smaller openings at higher pressure. Run a fireplace on the wrong fuel setup and you get lazy flames, soot on the glass, and a genuine safety problem — which is why conversions are done with the manufacturer's kit, by a licensed tech, never by guesswork.
Everything you'd notice from the couch — flame look, heat output, controls — is engineered to match. A Kozy Heat Springfield 36 burning propane in a Fairview cabin feels the same as its natural-gas twin in a West Asheville bungalow.
Which fuel your address gets in WNC
Around here, geography usually makes the choice for you: natural gas runs along the Asheville and Hendersonville mains — Fletcher and Arden too — while propane is the fuel out in Fairview, Candler, Brevard, and the cabins tucked up our mountain roads. Natural gas means no tank and no delivery truck; propane means you can have real gas heat miles from the nearest main.
We see this weekly: a family assumes they can't have a gas fireplace because they're 'too far out.' They can — that's exactly what propane is for.
What it means for your installation
On natural gas, we tie into your existing house line or run a new one from the meter. On propane, we handle the regulator, piping, and appliance setup, and coordinate the tank itself with your propane supplier. Either way, this is the licensed part of the job: in North Carolina, running or extending a gas line is licensed work — a showroom or mason can sell you a beautiful firebox, but they legally can't connect it to fuel. We can, and we permit and pressure-test every line we run, with your county's inspector signing off. Call (828) 545-0525 for a free in-home assessment.
