If your Delaware County home has a fireplace, there is a good chance you have wondered whether to keep burning wood or switch to gas. Most homeowners in this area are not starting from scratch; they already have an existing chimney and firebox, and the real question is what to do with the system they have. The answer depends on chimney condition, liner status, the type of masonry work the chimney may need, and how the fireplace fits into your daily life. Understanding the practical differences between gas and wood helps you make a confident decision about the system that is already part of your home.
This guide walks through the factors that matter most when evaluating your existing fireplace system, from efficiency and maintenance to chimney condition and what it takes to restore a system that is not performing safely. Whether you are in Drexel Hill, Broomall, Wayne, Springfield, or the Main Line communities, Lou Curley’s Chimney Service holds the rare distinction of NFI Master Hearth Professional certification in wood, gas, and pellet, which means the assessments in this guide come from expertise across all fuel types rather than a bias toward one.
Heating Efficiency: Gas vs. Wood
The efficiency comparison between gas and wood-burning fireplaces is often misunderstood because the two types produce heat in fundamentally different ways.
A traditional open wood-burning fireplace operates at roughly 10 to 15 percent efficiency. Most of the heat generated by the fire goes straight up the chimney, and the draft created by the fire actually pulls heated room air up the flue, which can make the room colder in some situations. A wood-burning fireplace insert or a high-efficiency wood stove changes this equation dramatically, operating at 70 to 80 percent efficiency or higher by capturing heat that an open fireplace would lose.
A direct-vent gas fireplace operates at 70 to 85 percent efficiency, delivering consistent, controllable heat without the variability of a wood fire. A vented gas log set in an open fireplace operates at much lower efficiency, similar to an open wood fire, because the damper must remain open and heat escapes up the chimney. A ventless gas log set operates at near 99 percent efficiency but releases combustion byproducts into the living space.
The practical takeaway for Delaware County homeowners is that the efficiency comparison depends entirely on which specific configuration you are comparing. A direct-vent gas fireplace is more efficient than an open wood fireplace but comparable to a high-efficiency wood insert. If supplemental heating is your primary goal, the configuration matters more than the fuel type.
The maintenance requirements for gas and wood-burning fireplaces differ significantly, and this is often the deciding factor for homeowners choosing between the two.
Maintenance and Safety Requirements
Wood-burning fireplaces require annual chimney sweeping to remove creosote buildup, which is a natural byproduct of wood combustion. Creosote is the leading cause of chimney fires, and NFPA standards require annual inspection and cleaning. The chimney must be structurally sound, the flue liner must be intact, the damper must function properly, and the chimney cap must be in place. Wood fires also produce ash that needs to be removed from the firebox regularly, and the firebox and smoke chamber should be cleaned as part of the annual service. You also need a reliable supply of properly seasoned firewood, which means either purchasing wood or cutting, splitting, and storing it yourself with a minimum six-month seasoning period.
Gas fireplaces require less routine maintenance, but they are not maintenance-free. Annual inspection is still required by NFPA 211, covering gas leak detection, vent integrity, thermocouple and thermopile testing, pilot assembly cleaning, and burner port inspection. Gas fireplaces do not produce creosote, but the chimney or venting system still needs structural evaluation for weather damage, moisture intrusion, and component deterioration. The gas valve, ignition system, and safety components all require professional testing.
The practical difference is that wood-burning fireplaces require more hands-on involvement from the homeowner throughout the season, while gas fireplaces require less ongoing attention but still need professional annual service.
Cost Comparison: Gas vs. Wood-Burning
The cost comparison between gas and wood is less about installing something new and more about what it takes to get your existing system working safely and efficiently.
For homeowners who want to convert an existing wood-burning fireplace to gas, the most common path is installing gas logs or a gas insert into the firebox you already have. Vented gas logs typically run $700 to $3,500, while a gas insert with a new chimney liner typically costs $2,000 to $4,000. In either case, the chimney needs a professional evaluation first. If the existing flue liner is cracked or deteriorated, a new stainless steel liner will be part of the project cost. If the masonry itself needs repointing or waterproofing, those repairs apply regardless of whether you go gas or stay with wood.
For homeowners committed to wood burning, the condition of the existing chimney determines the scope and cost of the work. A wood-burning insert installed in an existing masonry fireplace typically costs $3,500 to $8,000, including the insert, chimney liner, and installation. If the existing fireplace has more serious issues, such as a damaged firebox, a failing flue, or masonry that is no longer safe for high-temperature wood fires, a full fireplace restoration using the Ahren-Fire system is an option worth understanding. Ahren-Fire is a complete correction of the fireplace and chimney system, rebuilding the smoke chamber, firebox, and flue to restore safe, efficient wood-burning performance. This type of restoration typically runs in the $14,000 range and is one of the more common projects Lou Curley’s handles for homeowners who want to keep burning wood but need the system brought back to a safe, functional condition.
Operating costs depend on local fuel prices and usage patterns. Natural gas in the Delaware County area is relatively affordable, and a gas fireplace operated 4 to 5 hours per day during the heating season might cost $30 to $80 per month. Wood heat costs depend on whether you purchase firewood or harvest it yourself. A cord of seasoned hardwood in the Delaware County area runs approximately $250 to $400, and a typical household using a fireplace or stove as supplemental heat might burn 2 to 4 cords per season.
Annual maintenance costs are comparable. A professional chimney sweep and inspection for a wood-burning fireplace costs $200 to $350 in Delaware County. A professional gas fireplace service costs $150 to $300. Over time, the maintenance costs are similar, though wood-burning systems may require more frequent masonry repairs due to the higher operating temperatures and greater creosote-related stress on the chimney.
The Experience: Ambiance and Convenience
The ambiance and experience of a gas versus wood fire is deeply personal, and it is the factor most often cited by homeowners as their primary motivation for choosing one over the other.
A wood-burning fireplace delivers an experience that gas cannot fully replicate. The smell of burning wood, the unpredictable dance of natural flames, the crackling and popping sounds, and the ritual of building and tending a fire are all part of an experience that many homeowners consider irreplaceable. There is a tactile, elemental quality to a wood fire that connects to something primal and deeply satisfying.
A gas fireplace delivers convenience that wood cannot match. Instant on and off with a switch or remote, precise temperature control, no ash cleanup, no wood storage, no chimney smoke on cold-start days, and the ability to enjoy a fire without any preparation. For homeowners with busy lifestyles, physical limitations, or homes without adequate wood storage space, gas provides the warmth and visual appeal of a fire without the labor.
Modern gas fireplace technology has narrowed the aesthetic gap considerably. High-end gas inserts and fireplaces now produce flame patterns that are remarkably realistic, with yellow and orange flames, glowing embers, and log sets that are nearly indistinguishable from real wood at a glance. But side by side with a real wood fire, most people can still tell the difference.
Delaware County Climate and Housing Considerations
For homeowners in Delaware County, the climate and housing stock create considerations that are specific to this region.
The long heating season, which runs from October through April in most years, means that whatever fireplace you choose will get significant use. If convenience is important because you want to use your fireplace frequently, a gas unit removes the barrier of wood preparation and cleanup. If you enjoy the process and have access to good firewood, wood burning provides a deeply satisfying heating experience through the cold months.
Most homes in Delaware County already have masonry chimneys that were originally built for wood burning. The question is rarely whether to build a new chimney; it is what the existing chimney needs to safely support whichever fuel type you choose going forward. Converting to gas requires a chimney inspection, and if the clay liner is cracked or deteriorated, a new stainless steel liner. Continuing with wood requires the same structural evaluation, plus ongoing maintenance like repointing and waterproofing. If the firebox or smoke chamber has deteriorated to the point where the system is no longer safe for wood burning, a restoration like the Ahren-Fire system can bring it back to full function rather than forcing you into a gas conversion you did not want.
Row homes and attached dwellings, which are common in parts of Drexel Hill and the surrounding communities, present additional considerations for wood burning. Smoke from a wood fire can affect neighboring properties, and some homeowner associations restrict or prohibit wood burning. Gas fireplaces eliminate the smoke concern entirely.
Lou Curley’s Chimney Service is uniquely positioned to guide Delaware County homeowners through this decision because of the NFI Master Hearth Professional certification across all three fuel types: wood, gas, and pellet. This triple certification is exceptionally rare and means that Lou Curley’s recommendations are based on expertise with every option rather than a preference for one fuel type. With 750+ Google reviews at 4.9 stars and recognition as Pennsylvania’s first CSIA Master Chimney Sweep, Lou Curley’s brings a level of credibility and depth of knowledge that few competitors in the Delaware County market can match.
Whether you want to stay with wood, convert to gas, or restore a fireplace that has not been safe to use in years, the starting point is the same: a thorough evaluation of your chimney and fireplace system.
Your Chimney’s Condition May Decide for You
In many cases, your chimney’s current condition is the single biggest factor in the gas versus wood decision. Most homes in Delaware County have existing masonry chimneys that are decades old, and the state of the liner, firebox, and masonry determines what is possible and what it will cost. If your home has an older chimney with a deteriorated clay liner, relining is necessary for either gas or wood. A stainless steel liner for a gas insert typically costs less than a liner rated for wood-burning applications because the temperature requirements are lower. If the chimney structure itself needs repointing, crown repair, or waterproofing, those costs apply regardless of fuel type. For chimneys with more extensive damage, including a failing smoke chamber or compromised firebox, the scope of work expands. This is where a thorough chimney evaluation matters most: the right assessment up front prevents expensive surprises later and tells you exactly which fuel options your chimney can safely support.
Lou Curley’s carries an important technical detail that affects the liner conversation. The stainless steel liners they install carry a transferable lifetime warranty, meaning the warranty follows the chimney, not just the original homeowner. This is a meaningful differentiator for homeowners who may eventually sell their home, as the warranty adds documented value to the chimney system.
Environmental considerations are becoming increasingly important to Delaware County homeowners. Wood burning produces particulate matter and contributes to local air quality concerns, particularly in denser residential areas. EPA-certified wood stoves and inserts produce dramatically less particulate matter than older appliances, reducing the environmental impact by up to 90 percent compared to uncertified units. Gas fireplaces produce virtually no particulate matter and produce lower carbon emissions per unit of heat than wood burning. For homeowners who prioritize environmental impact, gas has a clear advantage.
However, wood is a renewable fuel source when sourced sustainably, and the carbon released during combustion is part of the natural carbon cycle rather than the release of sequestered fossil carbon. The environmental analysis is more nuanced than it initially appears, and the best choice depends on your specific priorities and values.
Another practical consideration for Delaware County homeowners choosing between gas and wood is the impact on homeowners insurance premiums. Some insurance companies charge higher rates for homes with wood-burning fireplaces due to the perceived fire risk. Gas fireplaces are generally viewed as lower risk. The premium difference may be modest, but compounded over years of homeownership, it becomes part of the total cost of ownership comparison. Check with your insurance provider before making a final decision.

Frequently Asked Questions
Q: Is a gas or wood-burning fireplace better for heating?
A: The answer depends on the specific configuration. A high-efficiency wood stove or insert and a direct-vent gas fireplace both operate at 70 to 85 percent efficiency. An open wood fireplace and vented gas logs are both inefficient, operating at 10 to 15 percent. If heating is the priority, choose a high-efficiency insert or stove in either fuel type rather than an open fireplace or basic gas log set.
Q: Can I convert my wood-burning fireplace to gas?
A: Yes, and it is one of the most common projects for homeowners with existing masonry chimneys. Options include vented gas logs, ventless gas logs, or a gas fireplace insert. The key step is a professional chimney inspection before conversion, because the condition of your liner and masonry determines which options are safe and what additional work the chimney may need.
Q: Do gas fireplaces still need chimney inspections?
A: Yes. NFPA 211 requires annual inspection for all chimneys and venting systems regardless of fuel type. Gas fireplaces require inspection for carbon monoxide safety, gas leak detection, vent integrity, and chimney structural condition. The chimney serving a gas fireplace is still exposed to weather damage and freeze-thaw cycling even though it does not accumulate creosote.
Q: Which is cheaper to operate, gas or wood?
A: Operating costs depend on local fuel prices and usage patterns. In the Delaware County area, natural gas is relatively affordable, with a gas fireplace costing approximately $30 to $80 per month during regular use. Wood costs $250 to $400 per cord, with most households burning 2 to 4 cords per season for supplemental heat. If you have access to free or low-cost firewood, wood is cheaper. At retail firewood prices, the costs are often comparable.
Q: Are wood-burning fireplaces being banned?
A: Some municipalities and homeowner associations have enacted restrictions on wood burning, particularly during air quality advisory periods. Delaware County does not currently have a blanket ban on wood-burning fireplaces, but individual homeowner associations may have restrictions. EPA-certified wood stoves and inserts produce dramatically less smoke than older, uncertified appliances and are generally exempt from use restrictions.
Q: What certifications should a fireplace installer have?
A: Look for CSIA certification for chimney work and NFI certification for fireplace and hearth appliance installation. The NFI Master Hearth Professional designation, which Lou Curley holds in wood, gas, and pellet, represents the highest level of certification in the hearth industry and demonstrates expertise across all fuel types.
