This initial gas fireplace
One of the most common problems faced by homeowners with gas fireplaces is the pilot light going out or not staying lit. The pilot light is a small flame that ignites the gas burner, which produces the heat for your fireplace — if the pilot light goes out, your fireplace won't work.
Simple repairs like replacing thermocouples, pilot light adjustments, or cleaning can range from $75 to $200. Significant repairs or replacing components can be $1,000 (or more), including labor and parts.
But in general, an efficiently running modern gas fire kept clear of dust and debris should hit or exceed that 10 to 15-year mark before showing signs of wear. Older or cheaper models may start to struggle after 7–8 years. Regular servicing and maintenance will be essential to maximising lifespan potential.
The cost to replace a water heater gas valve is an average of $350 for labor and materials. Depending on the replacement part's price and labor rates in your area, your final cost could vary.
Ball valves tend to wear out over time and not seal off the flow of gas to and from your fireplace, causing a leak even when your gas fireplace or log starter pipe is turned off. When your fireplace is turned off but your gas valve smells like gas, then you leak and probably need a replacement valve.
The National Fire Protection Association (NFPA) recommends all fireplace owners with solid or liquid fuel appliances have annual safety & maintenance inspections. While gas fireplaces burn cleaner than wood, yearly safety and maintenance inspections are still essential to ensure they operate safely.
If you have either a gas fireplace insert or a direct vent fireplace, you should be able to leave your fireplace on continuously throughout the day.
As California moves to become the first state to ban natural gas-powered space and water heaters by 2030, a growing debate about what the ban means for homeowners, and any potential expansion to other appliances, is kicking off.
Gas Fireplace: $3,500-6,500 (New construction), or $4,000-8,000 (remodel)
Gas Fireplace
They are very convenient to use, as they can be switched on and off at the touch of a remote or button. While they preserve more heat than a wood-burning fireplace, they still lose around 75% of the heat they generate. The cost of the natural gas you burn can increase your heating bill.
It is highly recommended that you contact a licensed gas service provider to conduct maintenance on your fireplace at least once per year. Maintenance on gas components should not be completed by the homeowner as damage to any of the gas components could be potentially dangerous.
Faulty thermostat, thermopile, or thermocouple.
Depending on the age of your unit, you'll have a thermostat or thermopile between your gas valve and pilot light that contributes to ignition. If it's loose or faulty, or if your thermostat is malfunctioning, it may prevent your fireplace from turning on.
You start smelling strange odors
This smell should go away after three to four hours of use. A dirty fireplace with excessive pet hair or dust can also produce an odor. If you smell rotten eggs, call for help immediately, as you likely have a gas leak.
Real estate agents say homes with fireplaces often get offers above the asking price. Gas fireplaces are especially desirable because of their relatively easy maintenance.
Energy Conservation
The best reason to turn the pilot light off during summer is to conserve energy, especially now that prices are rising. Leaving the pilot light on consumes more gas, and it doesn't make sense to pay for it when you're not using it.
A well-maintained furnace will have an efficiency rating of approaching 95%, while a gas fireplace is likely to be below that (though some are in the 90% class) and will therefore cost more per therm.
Gas line inspections and repairs typically range from $150 to $400 but can be higher if extensive gas line work is necessary. Soot Buildup: Soot accumulation can affect the fireplace's efficiency and safety. Cleaning and maintenance to clear soot and debris cost between $200 and $300.
Fireplace gas valve replacement cost
Replacing a fireplace gas valve costs $150 to $300 on average. The gas valve controls the flow of fuel.
Common Signs of a Failing Thermocouple
Here are some common indicators: Difficulty Lighting the Fireplace: If you struggle to light your fireplace, or if it takes several tries to keep the pilot lit, it could suggest that the thermocouple is not sensing the flame correctly and is failing to keep the gas supply open.
Is it normal to smell gas when using a gas fireplace? In fact, a faint gas smell is an unavoidable consequence of using gas fireplace logs. More than anything, it's a sign your fireplace is working the way it should.
