Do I need a bigger propane tank if I add a gas fireplace?
In Flat Rock, the housing tells the story. These historic homes — some dating to the 1800s with oversized open masonry fireplaces — are usually on natural-gas service, so a sealed insert becomes a permitted branch line with no tank at all. Where a historic home sits on propane instead, an insert's low fuel draw fits a standard tank easily.
Sealed inserts in 1800s hearths
Flat Rock's grand old open fireplaces and aging clay flue liners pull cold-air drafts into the room and lose most of their heat up the chimney. Dropping in a sealed gas insert fixes the draftiness while preserving the historic character — and because a sealed unit sips fuel, it's a light load whether it's on gas or propane. That's a much lighter job than a big open firebox, which is why the tank question rarely bites here.
On the main or on a tank
Much of the Flat Rock village and the Highland Lake and Kanuga areas are on natural-gas service, so there's no propane tank to size — we run a licensed branch, pull the Henderson County permit, and pressure-test it. For the historic properties that predate the mains and still run propane, an insert's 20,000-or-so BTU disappears into a whole-home 250- or 500-gallon tank. Small cylinders and marginal tanks are the only ones we'd flag for an upsize.
