How much natural gas does a gas fireplace use, and what does it cost per hour?
In Marshall the venting drives the decision as much as the fuel. Steep hillside lots and multi-story downtown buildings built against the mountainside make chimney routing tight, so a no-chimney direct-vent unit shines. Fuel is mixed: on a gas line a 25,000-BTU unit runs about 0.25 therms an hour; on propane, about 0.27 gallons at roughly 91,500 BTU a gallon.
Tight lots make direct-vent the easy answer
The homes climbing Marshall's hillsides and the narrow buildings stacked in the revitalized downtown don't leave room for a conventional chimney chase, and the French Broad gorge's shifting air causes downdrafts that plague open flues anyway. A sealed direct-vent fireplace vents its coaxial pipe straight out a sidewall — no chimney required — which sidesteps both the routing headache and the draft problem. It also keeps most of its 25,000 BTU in the room, so the fuel you're paying for by the hour actually becomes heat.
Cool, damp gorge evenings
The French Broad gorge keeps Marshall's evenings cool and damp much of the year, which extends the season a fireplace earns its keep and makes a thermostat-controlled burner worth having — it eases down once the room's comfortable rather than holding full output against damp mountainside air. Whether you're on gas or propane, that modulation is where the per-hour number quietly drops on a long, mild-but-cool evening.
