Frequently Asked Questions

  • A propane fireplace insert is a self-contained heating appliance installed inside an existing wood-burning fireplace opening, using propane from an external tank to produce a controllable flame inside a sealed firebox. It connects to a propane supply line and a venting system that exhausts combustion gases outdoors, most commonly through the existing chimney. Unlike open wood-burning fireplaces, the sealed design retains heat in the room rather than sending it up the chimney.

  • A propane fireplace insert uses approximately one gallon of propane per 100,000 BTUs of output, so a 50,000 BTU model will consume roughly one gallon every two hours of active use. On average, a direct-vent gas fireplace insert uses around 300 gallons per year, though usage can range from 50 to 500 gallons annually depending on climate, frequency of use, and whether it's run for ambiance or as a primary heat source. Factoring your insert's BTU rating into your propane budget before purchasing is strongly recommended.

  • Propane fireplace inserts are dramatically more efficient than traditional wood-burning fireplaces — a wood fireplace is only about 5–10% efficient, with 90–95% of the heat escaping up the chimney. Most high-efficiency propane fireplace inserts carry efficiency ratings of 70% to 90%, meaning the vast majority of fuel you burn actually heats your home. Direct-vent systems further improve indoor air quality by drawing combustion air from outside rather than consuming heated room air.

  • It is recommended to use a tank no smaller than 100 lbs, as small cylinders like standard 5-gallon or grill-style tanks are not sufficient for most propane fireplace insert models. The propane tank must always be stored outdoors, and the exact capacity needed will depend on your insert's BTU rating and how frequently you plan to use it. Your local propane supplier can assess your home and recommend the right tank size for your specific setup.

  • Propane fireplace inserts require far less maintenance than wood-burning fireplaces — there's no creosote buildup, no chimney sweeping, and no ash to remove. Typically, a once-a-year inspection by a qualified service technician and occasional glass cleaning is all that's needed to keep the unit running smoothly. Some models may also require seasonal tasks like cleaning propane orifices and testing the ignition system.
