What size propane tank do I need to run a gas fireplace?
In Mars Hill, the rural Spring Creek and Gabriels Creek valleys largely run on propane or wood, so if you're adding a gas fireplace out there, a tank is part of it — and a fireplace on its own fits a 120-gallon stationary tank. It's one of the colder spots we serve, which is the main reason to skip a small cylinder.
Cold valleys, easy fire
A lot of Mars Hill homeowners want a gas fireplace precisely because it's effortless — flame at the flip of a switch, no hauling wood, no cold-start smoke. For that to hold up on a cold rural morning, the tank has to keep feeding it. Propane vaporizes inside the tank before it burns, and a small bottle can't make vapor fast enough when it's frigid; a stationary tank has the surface area to keep the flame steady.
How much tank
On its own a fireplace sips — 20,000 to 40,000 BTU an hour — so a modest 120-gallon stationary tank covers it, with a paired set of 100-pound cylinders workable at the small end. The moment the tank also runs a furnace or water heater, you're in 250- to 500-gallon range and the fireplace barely counts. Your propane supplier sizes it.
