How Each Fireplace Type Works
Before comparing pros and cons, it helps to understand the basic differences in how these two systems operate.
How a Wood Burning Fireplace Works
A wood burning fireplace uses a traditional masonry or prefabricated firebox where you load and light seasoned firewood. The fire heats the room through radiant heat from the flames and hot coals, while smoke and combustion gases rise through a chimney or flue and exit your home. Air from the room is drawn into the firebox to feed the fire, which also pulls heated air out of your living space and up the chimney. A damper controls airflow and must be opened before lighting a fire and closed after the fire is fully extinguished to prevent cold drafts.
How a Natural Gas Fireplace Works
A natural gas fireplace connects to your home’s Enbridge gas supply through a dedicated gas line. It produces a controlled flame over ceramic logs, glass beads, or decorative stones. Modern direct-vent gas fireplaces use a sealed combustion system — drawing outside air for combustion and venting exhaust through a coaxial pipe — which means no chimney is required and no heated room air is lost. You control the flame with a wall switch, remote, thermostat, or even a smartphone app.
Gas Fireplace vs Wood Fireplace: Complete Comparison
Here’s how the two options stack up across every factor that matters to Ottawa homeowners:
| Feature | Natural Gas Fireplace | Wood Burning Fireplace |
|---|---|---|
| Heating Efficiency | 70–90% (direct vent) | 10–25% (open masonry) |
| Heat Output | 20,000–50,000 BTU | 20,000–80,000 BTU (mostly lost up chimney) |
| Ease of Use | Switch, remote, or thermostat — instant on/off | Manual — gather wood, build fire, tend flames |
| Installation Cost | $3,500–$8,500 (new direct vent) | $8,000–$22,000+ (new masonry with chimney) |
| Annual Operating Cost | $200–$500/year (natural gas) | $0 (free wood) to $1,500+ (purchased firewood) |
| Maintenance | Annual inspection — no ash, no creosote | Ash cleanup after every use + annual chimney sweep |
| Chimney Required? | No (direct vent through wall) | Yes — full masonry or prefab chimney |
| Air Quality Impact | Minimal — sealed combustion | Smoke, particulates, and indoor air quality concerns |
| Ambiance | Realistic flames — no crackling or wood aroma | Authentic crackling, aroma, dancing flames |
| Power Outage Use | Yes — most models work without electricity | Yes — fully independent of electricity |
| Ottawa Building Permit | Required for gas line work | Required for masonry fireplace & chimney |
| Home Resale Value | Strong appeal to modern buyers | Strong appeal to traditional buyers |
Heating Efficiency: Where Gas Fireplaces Dominate
This is the single biggest difference — and it matters enormously in Ottawa’s climate, where winter temperatures regularly drop below -20°C and heating season lasts five to six months.
A traditional open wood burning fireplace is surprisingly inefficient. While the fire itself produces plenty of heat, up to 75–90% of that heat escapes straight up the chimney. Even worse, an open fireplace actively pulls heated air from your home to feed combustion, creating a net negative heat effect in some cases — your furnace works harder to compensate for the warm air being sucked out of the room.
A modern direct-vent natural gas fireplace operates at 70–90% efficiency. The sealed combustion design means no heated room air is consumed, and the heat produced stays in your home. Many gas fireplaces include built-in fans that circulate warm air throughout the room, functioning as a genuine supplemental heat source that can reduce the load on your furnace and lower your energy bills.
For Ottawa homeowners who want a fireplace that actually helps heat their home — not just look pretty while your furnace does all the work — a gas fireplace is the clear winner.
Cost Comparison: Installation and Operating Costs in Ottawa
The cost picture depends on whether you’re looking at upfront installation, ongoing fuel and operating expenses, or long-term total cost of ownership.
Installation Cost
A new natural gas fireplace installation in Ottawa typically costs $3,500–$8,500, depending on the model, venting configuration, and whether a new gas line needs to be run. Direct-vent models are the most popular choice because they don’t require a traditional chimney — just a coaxial vent pipe through an exterior wall. This means you can install a gas fireplace in virtually any room of your home, including basements, bedrooms, and additions.
A new wood burning fireplace with a full masonry chimney is significantly more expensive — typically $8,000–$22,000+ depending on materials and chimney height. The City of Ottawa requires a building permit for masonry fireplace and chimney installations, as well as for woodstove and chimney installations, fireplace inserts with chimney liners, and pre-manufactured fireplace and chimney systems. The permitting and inspection process adds time and cost to wood fireplace projects.
Annual Operating Cost
Operating a natural gas fireplace on Enbridge natural gas costs roughly $0.40–$0.50 per hour in Ottawa, depending on the BTU output and current gas rates. If you use your fireplace for two hours per evening during the six-month heating season (roughly 360 hours), that’s approximately $150–$180 in gas costs per year. Gas fireplaces also have very low maintenance costs — an annual inspection runs $100–$200.
A wood burning fireplace can be nearly free to operate if you have access to your own firewood supply. However, most Ottawa homeowners purchase firewood. A full cord of seasoned hardwood (maple, oak, or birch) in the Ottawa region runs $350–$450 delivered. Most households burn 1–3 cords per season depending on usage frequency, putting annual fuel costs at $350–$1,350. Add in a mandatory annual chimney sweep ($200–$400) and the operating costs can exceed a gas fireplace, especially for heavy users.
Long-Term Value
Over 10–15 years, a gas fireplace typically costs less to own when you factor in the lower installation cost, predictable fuel expenses, and minimal maintenance. Wood fireplaces can be economical if you have free firewood access, but the maintenance requirements and chimney upkeep add up. Both types increase home resale value — surveys consistently show that fireplaces are among the top features Ottawa homebuyers look for.
Maintenance and Upkeep
The maintenance gap between gas and wood fireplaces is one of the biggest factors in the gas fireplace vs wood fireplace debate.
Gas Fireplace Maintenance
A natural gas fireplace requires remarkably little upkeep. There’s no ash to clean, no creosote buildup, and no chimney to sweep. The recommended maintenance includes an annual professional gas fireplace inspection and service, occasional cleaning of the glass viewing panel, checking the condition of ceramic logs or media, and verifying the pilot light and ignition system are working correctly. Gas Man Ottawa provides comprehensive gas fireplace repair and maintenance services across Ottawa.
Wood Burning Fireplace Maintenance
A wood burning fireplace demands regular, hands-on maintenance. After every use, you need to remove ash once it accumulates past 1–2 inches in the firebox. Wood fires produce creosote — a highly flammable tar-like residue that accumulates inside the chimney. If creosote isn’t removed regularly, it can ignite and cause a dangerous chimney fire. An annual professional chimney sweep and inspection is not optional — it’s essential for safety. You’ll also need to inspect the firebox, damper, and chimney cap for cracks and deterioration, source, split, and properly season firewood (hardwood needs 6–12 months of drying), and store firewood outdoors, away from the house, to prevent pest and moisture issues.
For busy Ottawa families who want a fireplace they can enjoy without the labour, gas is the low-maintenance choice by a wide margin.
Safety Comparison
Both gas and wood fireplaces are safe when properly installed and maintained, but they present different risk profiles.
Gas Fireplace Safety
Modern natural gas fireplaces are engineered with multiple safety features. The sealed glass front prevents sparks, embers, or open flames from reaching your living space. Direct-vent models bring in outside air for combustion and exhaust all byproducts outdoors, so no combustion gases enter your home. Built-in oxygen depletion sensors (ODS) automatically shut off the gas if oxygen levels drop. The main safety considerations are ensuring the gas line and connections are properly installed by a TSSA-licensed gas fitter and maintaining functioning carbon monoxide detectors in your home.
Wood Burning Fireplace Safety
A wood burning fireplace carries more inherent risks. Open flames can throw sparks and embers into the room, creating a fire hazard — a metal screen or glass doors are essential. Creosote buildup in the chimney is a leading cause of house fires in Canada. Smoke can backdraft into your home if the damper isn’t properly managed, affecting indoor air quality and triggering health concerns for those with asthma or respiratory conditions. The fire must never be left unattended, and proper fireplace tools, a fire extinguisher, and smoke and CO detectors are all required.
Both types of fireplaces require proper safety inspections. Gas fireplaces are generally considered safer for families with young children and pets because of the sealed combustion design and absence of open flames, sparks, and hot ash.
Ambiance and Experience: Where Wood Fireplaces Shine
If the nostalgic, sensory experience of a fire is what matters most to you, a wood burning fireplace is hard to beat. The crackling sound of burning birch, the earthy aroma of a hardwood fire, the unpredictable dance of real flames over glowing coals — these are experiences a gas fireplace can replicate visually but not fully match.
That said, modern natural gas fireplaces have come a long way. High-end models produce tall, realistic flames over detailed ceramic log sets that closely mimic the look of a real wood fire. Some even incorporate glowing ember beds and randomized flame patterns. The visual difference between a premium gas fireplace and a wood fire has narrowed dramatically in recent years — many visitors won’t be able to tell the difference at a glance.
What gas fireplaces offer that wood can’t is on-demand ambiance. Flip a switch and enjoy a fire in seconds. No gathering wood, no building a fire, no waiting 30 minutes for it to get going. On a -25°C Ottawa weeknight when you want to relax after work, that instant gratification is a genuine luxury.
Gas Fireplace Types for Ottawa Homes
If you’re leaning toward gas, it helps to understand the different installation options available:
Direct-Vent Gas Fireplace (Most Popular)
The most common type installed in Ottawa homes. Direct-vent units use a sealed combustion system with a coaxial vent pipe that draws fresh air from outside and exhausts combustion gases through the same wall penetration. No chimney required. These can be installed in virtually any room — living rooms, basements, bedrooms, even bathrooms. Efficiency ratings of 70–90%.
Gas Fireplace Inserts
Gas fireplace inserts are designed to fit inside an existing wood burning fireplace opening, converting it to gas. This is the most popular option for Ottawa homeowners who already have a wood fireplace but want the convenience of gas. The insert uses a stainless steel liner inside the existing chimney for venting. A gas line is run to the firebox, and the result is a dramatically more efficient, lower-maintenance fireplace in the same location. Insert conversions typically cost $2,500–$6,000 installed, depending on the model and liner requirements.
Ventless (Vent-Free) Gas Fireplace
Ventless models require no venting at all, making them the easiest to install. However, they release combustion byproducts directly into your living space. While modern ventless models include oxygen depletion sensors and produce very low emissions, they are not recommended as a primary heat source and are restricted by building codes in some situations. Direct-vent models are the safer and more popular choice for Ottawa homes.
Linear (Contemporary) Gas Fireplace
Linear fireplaces feature a long, wide, rectangular viewing area that creates a modern wall-of-flame aesthetic. These are increasingly popular in Ottawa new builds and renovations. They can be installed at eye level, recessed into a wall, or used as a room divider with see-through models. Linear fireplaces often use glass beads, crystals, or river rocks instead of traditional log sets.
Converting a Wood Fireplace to Gas in Ottawa
Many Ottawa homes — especially those built before the 1990s — have existing wood burning fireplaces that homeowners want to convert to gas. This is one of the most popular gas fireplace installation projects we handle at Gas Man Ottawa.
What’s Involved in a Conversion
A wood-to-gas fireplace conversion involves several key steps. First, the existing wood fireplace is inspected to confirm it can accept a gas insert and that the chimney is structurally sound. A gas fireplace insert sized for your firebox is selected, and a stainless steel chimney liner is installed to properly vent the gas appliance. Our TSSA-licensed gas fitters run a dedicated natural gas line from your home’s gas system to the fireplace. The insert is installed, all gas connections are pressure-tested, and the system is commissioned and tested for safe operation.
Conversion Cost in Ottawa
A complete wood-to-gas fireplace conversion in Ottawa typically runs $2,500–$6,000, including the gas insert, chimney liner, gas line installation, and labour. The exact cost depends on the insert model, liner length, distance of the gas line run, and any repairs needed to the existing fireplace structure.
Why Convert?
Homeowners convert for several reasons: they want the convenience of instant on/off, they’re tired of buying, hauling, and storing firewood, they want more efficient heating from their fireplace, they have safety concerns about creosote and chimney fires, they want to improve indoor air quality, or their aging wood fireplace needs expensive masonry repairs and converting to gas is more cost-effective than rebuilding.
Ottawa-Specific Considerations
Several factors unique to Ottawa and Ontario should inform your fireplace decision:
Building Permits
The City of Ottawa requires building permits for the installation of masonry fireplaces and chimneys, woodstoves and chimneys, pellet stoves, fireplace inserts with chimney liners, and pre-manufactured fireplace and chimney systems. Gas fireplace installations require TSSA compliance for the gas fitting work. Gas Man handles all necessary permitting and inspections as part of your gas fireplace installation.
Ottawa’s Cold Climate
Ottawa’s extended heating season (roughly November through April) means your fireplace gets heavy use. The efficiency difference between a gas fireplace (70–90%) and a traditional wood fireplace (10–25%) becomes more significant the more you use it. In a city where -20°C to -30°C cold snaps are routine, having a fireplace that actually contributes to heating your home — rather than pulling warm air up the chimney — makes a meaningful difference in comfort and energy bills.
Enbridge Natural Gas Availability
Most Ottawa homes in urban and suburban areas are connected to Enbridge natural gas, making gas fireplace installation straightforward. If your home already has a gas furnace, water heater, or gas stove, running an additional gas line to a new fireplace location is a relatively simple job for a licensed gas fitter. Rural Ottawa properties without natural gas service can use propane as an alternative fuel source for gas fireplaces.
Insurance Considerations
Home insurance providers in Ontario may require disclosure of your fireplace type. Wood burning fireplaces and woodstoves can sometimes result in higher premiums due to the increased fire risk, and insurers may require proof of annual chimney inspections. Gas fireplaces are generally viewed more favourably by insurers. Check with your provider before installing either type.
Power Outages
Both gas and wood fireplaces can provide warmth during Ottawa’s frequent power outages. Most gas fireplaces with a standing pilot light or battery backup ignition will operate without electricity, though the built-in fan won’t run. A wood fireplace is fully independent of electricity. If power outage preparedness is a top priority, consider pairing a gas fireplace with a natural gas standby generator for complete home protection.
Which Fireplace Is Right for Your Ottawa Home?
Here’s a simple framework to guide your decision:
Choose a Natural Gas Fireplace If You Want:
Maximum heating efficiency in Ottawa’s long winters, instant on/off convenience with a switch or remote, virtually zero maintenance and cleanup, the ability to install in any room (no chimney needed), improved indoor air quality with sealed combustion, a safer option for homes with young children or pets, or lower long-term ownership costs.
Choose a Wood Burning Fireplace If You Want:
The authentic crackling, aroma, and ambiance of a real wood fire, full independence from gas and electricity during power outages, an activity and ritual around building and tending fires, access to free or low-cost firewood, or a traditional aesthetic that matches a heritage or country-style home.
Consider a Gas Fireplace Insert If:
You already have a wood burning fireplace but want the benefits of gas. A gas fireplace insert gives you the best of both worlds — you keep the existing fireplace opening and mantle while gaining the efficiency, convenience, and low maintenance of a natural gas fireplace.

Frequently Asked Questions: Gas vs Wood Fireplaces in Ottawa
Is a gas fireplace more efficient than a wood fireplace?
Yes, significantly. A direct-vent natural gas fireplace operates at 70–90% efficiency, meaning most of the heat produced stays in your home. A traditional open wood burning fireplace operates at only 10–25% efficiency because the majority of heat escapes up the chimney. In Ottawa’s long, cold winters, this efficiency difference translates to real comfort and energy savings.
How much does it cost to convert a wood fireplace to gas in Ottawa?
A complete wood-to-gas fireplace conversion in Ottawa typically costs $2,500–$6,000, including the gas fireplace insert, stainless steel chimney liner, gas line installation, and labour. The exact cost depends on the insert model and the specifics of your existing fireplace. Call Gas Man at (613) 880-3888 for a free estimate.
Can a gas fireplace work during a power outage?
Yes, most natural gas fireplaces with a standing pilot light or battery backup ignition will operate during a power outage. You’ll get heat and flame, though the built-in fan (if equipped) won’t run without electricity. This makes gas fireplaces a reliable supplemental heat source during Ottawa’s storm-related outages.
Do I need a chimney for a gas fireplace?
No. Direct-vent gas fireplaces vent through a small coaxial pipe that exits through an exterior wall. This means you can install a gas fireplace in virtually any room of your Ottawa home — living rooms, basements, bedrooms, bathrooms, or additions — without building a chimney. This is one of the biggest advantages of gas over wood.
How long do gas fireplaces last?
A well-maintained natural gas fireplace typically lasts 15–25 years. Annual professional maintenance and inspection is the key to maximizing lifespan. Common repairs like thermocouple replacement and pilot light adjustment are straightforward and affordable.
Does a gas fireplace increase home value?
Yes. Surveys consistently show that fireplaces are among the top features homebuyers look for. Both gas and wood fireplaces add resale value, though gas fireplaces are increasingly preferred by modern buyers for their convenience, efficiency, and low maintenance. In Ottawa’s real estate market, a well-installed gas fireplace is a strong selling point.
Is a wood burning fireplace bad for indoor air quality?
Open wood burning fireplaces can negatively affect indoor air quality by releasing fine particulates, smoke, and combustion gases into your living space. People with asthma, allergies, or respiratory conditions may experience symptoms. Sealed direct-vent natural gas fireplaces don’t impact indoor air quality because all combustion occurs in a sealed chamber with outdoor air intake and exhaust.
What maintenance does a wood burning fireplace need?
A wood burning fireplace requires ash removal after each use, an annual professional chimney sweep to remove creosote buildup (a leading cause of chimney fires), chimney cap and damper inspection, firebox inspection for cracks in the masonry, and proper firewood seasoning and storage. The annual chimney sweep alone typically costs $200–$400 in Ottawa.
Can Gas Man install a wood fireplace?
