What size propane tank do I need to run a gas fireplace?
In Waynesville, cold decides as much as capacity — at nearly 2,650 feet the heating season runs about three weeks longer than Asheville's, so a fireplace here logs more hours. A fireplace alone still fits a 120-gallon stationary tank; the reason to avoid a small cylinder is that mountain cold makes it struggle to keep the flame up.
Vaporization is the whole game up here
Propane only burns after it turns to vapor inside the tank, and that happens along the tank's wetted wall. A little cylinder has almost no surface to work with, so on a single-digit Hazelwood morning it can frost over and the flame drops right when you want it most. A 120-gallon stationary tank has the wall area to keep making vapor through a cold snap — which is why we steer nearly every permanent Waynesville fireplace toward one over a portable bottle.
One appliance or several
On its own a fireplace draws only 20,000 to 40,000 BTU an hour and barely dents a tank. But older Hazelwood homes often lean on the hearth for real heat, and if the same propane also feeds a furnace and water heater, you're already in 250- to 500-gallon territory — the fireplace becomes a rounding error and the big appliances set the size.
