Gas Fireplace Service in Barrie, Orillia & Simcoe County

A gas fireplace is two things at once: a focal point in the room and, if you pick the right one, a real source of heat that keeps working when the power is out. Which fireplace is right for you depends on whether you're retrofitting an old wood-burning firebox, framing one into a new wall, or just want a freestanding stove — and on whether you mostly want the look of a fire or genuine heat for a room or a zone of the house.

Below we lay out the choices the way we'd explain them at your kitchen table: the unit type, how it vents, what fuel it runs on, how it lights, and how much heat it actually puts out. None of it is complicated once you see it laid out, and there's no single “best” — the right answer depends on your home and what you want the fireplace to do.

Whatever you choose, a gas fireplace has to be installed by a licensed gas technician — in Ontario that work is regulated by the TSSA, and it isn't a DIY job. Relica Comforts handles new installs, conversions, and repairs across the GTA up to Barrie and Simcoe County, and we confirm the exact unit and venting that suits your home at your free quote.

Venting is the single biggest factor in how efficient and how safe a gas fireplace is, and it's the part homeowners think about least. There are three approaches, and for almost every new install we point people to the first one.

Direct-ventis the modern standard. It's a sealed combustion system: a co-axial pipe pulls outside air in for the flame and pushes the exhaust back out through the same wall or roof penetration. Because it's sealed off from the room, it doesn't draw your heated indoor air up a chimney, it doesn't risk pulling combustion gases into the house, and it keeps far more of the heat it produces. No chimney required — it can vent straight through an exterior wall. If you're installing new, this is almost always the right call.

Natural-vent (B-vent)runs its exhaust up an existing chimney or a vertical flue and uses indoor air for combustion. It's simpler in a home that already has a chimney, but it's noticeably less efficient — a chunk of your warm room air goes up the flue. These tend to be decorative units rather than serious heaters.

Ventlessfireplaces have no flue at all and release their combustion products into the room. They're rare and restricted in many Ontario jurisdictions, and local code may not allow one at all. If you're set on a ventless unit, we'll check what's permitted in your municipality before anything else — but in most cases we'll steer you to a direct-vent model instead.

This is the question that should drive the whole purchase. Some fireplaces are there for atmosphere — the fire is the point, and any warmth is a bonus. Others are built to genuinely heat a room or a zone of the house and take real load off your furnace. The difference shows up in two places: the BTU output the unit is rated for, and whether it has a heat-circulating blower to push warm air out into the room instead of letting it pool at the fireplace.

If heating is the goal, that's where venting comes back in. Gas fireplaces aren't rated by AFUE the way a furnace is — they use a steady-state or fireplace-efficiency rating instead. A direct-vent unit with a blower is far more efficient than a decorative B-vent model, so for real supplemental heat we point you at direct-vent, a blower, and a higher efficiency rating.

Sizing follows from that. If the fireplace is meant to heat, we match its BTU output to the size of the room — an oversized unit will run you out of the room and leave it uncomfortably hot, which is a more common mistake than undersizing. If it's mainly for ambiance, output matters less and you can choose more on looks. We work this out with you at the quote rather than guessing from square footage.

Gas fireplaces are long-lived, so most of our visits are repairs and tune-ups rather than replacements. The parts that wear are predictable: the pilot or igniter, the thermocouple and thermopile (the safety sensors that prove the flame is lit), the gas valve, the blower, and the glass gasket that seals the front. Most of those are single-visit fixes, and our technicians carry the common ones on the truck.

Because a fireplace is a combustion appliance inside your living space, we recommend an annual inspection — ideally in early fall before the season starts. It's a safety check as much as a cleaning: confirming the venting is clear, the burner and pilot are clean, and combustion is complete with no carbon monoxide spilling into the room.

And if you've still got a wood-burning fireplace you rarely use because of the work involved, converting it to a gas insert is one of the more satisfying upgrades we do — cleaner, more efficient, controllable with a switch or remote, and a genuine heat source instead of a draft up the chimney.
