How much natural gas does a gas fireplace use, and what does it cost per hour?
Many Mills River homes sit on large rural lots served by propane, not a gas main, so you're pricing per gallon: a 30,000-BTU Kozy Heat Springfield 36 uses about a third of a gallon an hour on high, since propane holds roughly 91,500 BTU a gallon. Multiply by your supplier's per-gallon rate, and less as it modulates.
Propane math, and the tank in the yard
Out among the farmland and forest, the fuel question answers itself — most properties here run propane, so cost per hour is gallons, and there's a delivery schedule behind it rather than a meter. Propane burns hotter per unit than natural gas and needs its own orifices; a unit converted correctly for LP sips fuel cleanly, while a mis-set one soots and wastes. Because propane usually costs more per BTU than natural gas, a sealed direct-vent appliance that keeps the heat indoors pays you back faster here than it would in town.
An open valley made for outdoor fire
Mills River's wide, open valley is built for outdoor living, and a gas fire pit runs by different rules — no thermostat, so it burns closer to its nameplate the whole time it's lit. A Napoleon Uptown square fire pit at 60,000 BTU LP uses roughly two-thirds of a gallon an hour, which is worth knowing before entertaining season. Plan the line and the pad in late spring, before the evenings you actually want to use it.
