What Do I Need to Know Before Getting a New Gas Fireplace Installation?
Before you embark on a gas fireplace installation, there are some crucial things to remember:
- Type of Fireplace Insert: Gas fireplace Insert come in vented and ventless varieties. The vented kind is more costly because it requires a venting system, whereas the ventless ones are less costly but might need special attention to air quality.
- Size & Design: The size of the insert will determine how much heat it can generate and how it will fit into your existing space. Larger models may require additional work during installation, thus increasing the overall cost.
- Safety Requirements: Gas fireplaces must meet specific safety codes, so be sure to work with licensed professionals who understand local building codes and regulations.
- Installation Complexity: If you already own a wood-burning fireplace, installing a gas insert might require extra labor, which could influence the price of the installation.
Gas Fireplace Cost Factors
Some elements will contribute to the overall price of gas fireplace installation. Knowing these factors will better prepare you for what to anticipate.
- Type of Gas Fireplace
The gas fireplace model you picked greatly contributes to the price. There are two main categories: vented and ventless.
- Vented: These Vented Gas Fireplace are pricier because they have a venting system that directs to the outside of your residence. They are more heat-efficient and tend to be favored in locations with strict air quality laws.
- Ventless: They don't need a vent and tend to be less expensive. However, they can make the indoor air more humid, which may not be permitted in some regions based on the air quality requirements of a Ventless Gas Fireplace.
- Existing Fireplace Setup
If you happen to already have a conventional wood-burning fireplace, it may take major changes to convert it into a gas fireplace. This may involve modifying the opening size, installing venting, or running a gas line. If you lack a fireplace in the first place, installing a fresh setup is likely to be more expensive as it includes both the fireplace and the required plumbing, gas lines, and venting system.
- Size
The dimensions of the gas fireplace also greatly impact the price. A bigger fireplace uses more material, and installation can be more complicated, increasing labor costs. A standard insert may be cheaper, whereas a special order insert can greatly increase costs.
- Surround material
The type of material used for the surround also influences the overall installation cost. Surround materials that are typically used are stone, brick, tile, and metal, each with a unique look and cost. Brick and stone are usually more costly, but tile and metal can be more affordable choices.
- Permits
Depending on where you live, you might need permits to install a gas fireplace. Permits ensure that the installation complies with local safety codes and regulations. Permit fees can vary anywhere from $100 to $300, depending on your city or town.
- Labor
Labor fees will depend on the complexity of the installation and your area rates. On average, you can expect to pay between $500 and $1,500 for labor for a standard gas fireplace installation. It's always best to get quotes from several professionals to compare.
Gas Fireplace Ongoing Costs
After your gas fireplace is installed, there are ongoing costs that you will need to take into consideration.
Operating Costs
The cost to operate a gas fireplace depends mainly on the gas you are using, either natural gas or propane. Depending on the unit size and efficiency, it can cost anywhere from $1.50 to $3 an hour. Operating your gas fireplace short-term instead of continuously will reduce operating costs.
Maintenance
Regular maintenance is vital to keeping your gas fireplace at its prime. Annual servicing, including cleaning and inspecting the unit for any leaks, could cost anywhere from $100 to $300. Staying on top of maintenance will keep your gas fireplace safe and efficient for many years.
Repairs
As with any appliance, your gas fireplace can need repair at times. These could be faulty ignition systems, a broken thermostat, or even leaks in the gas lines. The cost of the repairs will vary, but you should budget $100 to $600 for most repairs.
DIY Gas Fireplace Installation vs. Hiring a Pro
Though it might be tempting to have your gas fireplace installed yourself, remember that the installation involves plumbing, electrical work, and gas lines. Professional installation ensures your unit is properly installed and meets local code requirements. A licensed contractor will also take care of any required permits and inspections, ensuring the job is performed correctly.
DIY installations may be cost-saving in the short run, but errors could result in safety issues, added repair costs, or even invalidating the manufacturer's warranty. For peace of mind and safety, paying for a professional is generally best.
How to Save Money When Installing a Gas Fireplace
While gas fireplace installation costs can seem steep, there are ways to save money:
- Opt for a Ventless Insert: If legal in your region, selecting a ventless version can help you avoid the cost of a venting system.
- Consider Off-Season Installation: Have your installation done in the off-season, usually spring or summer, and labor costs may be lower.
- DIY Surround Construction: Although professional gas insert installation is suggested, you may save some money by installing a basic surround yourself.
- Shop Around for Quotes: Ask for several quotes from established contractors to ensure you get the best value.
- Look for Package Deals: Some contractors or suppliers might give you a discount if you buy both the insert and the installation in one package.
