How much natural gas does a gas fireplace use, and what does it cost per hour?
Flat Rock's housing is the real story before the fuel is. Homes here date to the 1800s with oversized open masonry fireplaces and aging clay flue liners — magnificent, and heat-hungry. You're on a natural-gas main, so a sealed insert like the 25,000-BTU Kozy Heat Chaska 25L runs about 0.25 therms an hour and keeps the character while cutting the waste.
Old open hearths pull heat out of the room
Those grand original fireboxes in Historic Flat Rock were built for ambiance, not efficiency — an open masonry fireplace this size draws cold-air drafts into the room and sends warmed air up the flue, so it can actually cost you comfort while it burns. A gas insert slides right into the existing opening, preserves the mantel and surround the house was designed around, and turns a draft into a sealed 0.25-therm-an-hour heater. You keep the 1800s look and stop paying to warm the chimney.
Aging clay liners are the weak link
Clay flue liners that old crack and gap with time, which is both a draft problem and a safety one. A sealed direct-vent insert vents through its own liner or straight out, so the tired original flue stops carrying the load. When we run or extend the gas line to feed it, we pull the Henderson County permit and pressure-test the connection — licensed work that protects a historic home's insurance and its eventual sale.
