Natural gas is a fairly inexpensive form of energy, so a gas fireplace is inexpensive to run. Gas fireplaces cost 17-19 cents an hour to run, or about $60 annually, Electric Fireplaces Direct says.
In this regard, how much gas does a fireplace use per hour?
Most of the heat that is produced will go up the chimney in this case. For the equivalent in a gas insert or gas fireplace, a large could use about 40,000 BTU/hour and in this case would cost about $0.40/hour to operate for natural gas and about $1.31/hour for propane.
Beside above, how much does it cost to run a gas fireplace pilot light?
If natural gas is your fuel, it might cost anywhere from $7 to $10 a month. Using propane could kick that up to more than $20 per month. When a pilot light burns for long periods of time (like during the summer) without igniting the main burner, a film can develop on the glass doors of the fireplace.
Are gas fireplaces energy efficient?
Energy-Efficiency Gas fireplaces use between 7,000 and 16,000 BTUs, are between 70 and 90% efficient at converting energy to heat, and cost around $60 a year to run. Electric fireplaces have an output that is based on the electric current.
Is it okay to run a gas fireplace all day?
Leaving a gas fireplace running too long can increase the risk of fire or dangerous fumes. The length of time a gas fireplace can be left on depends on the type of gas fireplace you have. Some types can be left on continuously, while others should only be operated for a few hours at a time.
