Automated hardwood heat for a five-month London winter.

Most pellet stove and insert installations in London run $6,000-$10,000 CAD. A pellet insert going into an existing masonry firebox in one of London's older Old North or Woodfield homes tends to land toward the lower end, since the chimney chase is already there and the liner and power-vent kit are the main added cost. A freestanding pellet stove in a newer home without a chimney needs a fresh through-wall vent run, which pushes the project toward the top of that range. Either way, the City of London building department requires a permit, and most installers include that paperwork in their quote.

It does, just not as most homeowners' only heat source. With Enbridge Gas serving most of London, a lot of homes already run a gas furnace or a gas fireplace for primary comfort, so a pellet stove here usually gets bought as a second heat source—something that keeps a family room warm on its own, cuts the furnace's workload on the coldest nights, and still runs during a winter power blip if you add a battery backup for the auger and blower. Some buyers also just prefer the visible flame and the lower running cost per BTU that pellets offer over gas at London's current rates.

Given London's average winter low of -9.2°C and a moderate heating season compared with much of Ontario, most homes here do fine with a small to mid-size unit rated for 1,200-2,000 square feet, especially if it's supplementing an existing gas furnace rather than replacing it. Larger, older homes in neighbourhoods like Byron or Old South with higher ceilings and less insulation sometimes need the next size up to keep a main living area comfortable through a full evening burn. A local dealer will size it against your actual floor plan and insulation rather than square footage alone.

Yes. Installations go through the municipal building department, and the appliance and venting need to meet CSA B365 installation code. Most homeowners are surprised to learn that insurers commonly ask for a WETT inspection on pellet installs too, even though pellet appliances burn compressed sawdust rather than cordwood—WETT certification covers solid-fuel appliances generally, and having that documentation on file makes a home insurance claim or a future sale much smoother.

Regional brands like Lacwood and Energex are the two most commonly stocked pellets through hearth retailers serving the London area, typically running $400-$575 CAD a tonne depending on the season and how early you order. Buying a season's supply in late summer, before demand and pricing tighten up heading into November, is the standard local move. Because pellets are bagged and palletized rather than stacked like cordwood, storage is simpler—a dry garage corner or basement shelf handles a few tonnes without the space a wood rack needs.

No, and that's one of the bigger appeals for London homes without an existing masonry chimney. Pellet appliances use a power-vented system that runs horizontally through an exterior wall in many installs, avoiding the cost of a full Class A chimney run through the roof. Homes that do have an existing masonry fireplace can still route a pellet insert's vent liner up the old flue if that's the more practical path, but it's rarely required the way it is for a wood-burning setup.

Plan on cleaning the burn pot and ash tray every few days to weekly depending on how many bags a week you're feeding it, plus a full professional service once a year—ideally in September before the first cold nights arrive rather than mid-winter when local dealers are booked solid with installs. Given London's roughly five-month heating season, a stove running daily through that stretch accumulates enough ash and fly ash in the venting that skipping the annual service is the most common cause of a mid-winter auger jam or ignition failure.

Not without help—pellet stoves rely on electricity for the auger, igniter, and combustion blower, so a straight power outage stops them cold, unlike a wood stove. London doesn't see outages as often as areas prone to major ice storms, but Middlesex has had its share of ice and windstorm events that knock out Hydro One or Alectra Utilities service for a day or more. Homeowners who want outage resilience typically pair a pellet stove with a small battery backup or generator rated for its low draw, or keep a wood-burning appliance elsewhere in the house as a true off-grid fallback.

Some municipalities across this hardwood-rich part of Ontario require certified low-emission appliances in new construction, and while that language is usually aimed at wood stoves, it's worth confirming with your local dealer if you're finishing a new build or an addition in London. In practice this rarely limits your options—virtually every pellet stove sold through a manufacturer-authorized dealer today is already EPA and CSA certified—but it's a five-minute check worth doing before you finalize a model, especially if your project is going through the building department alongside other new-construction permits.

Because a fireplace is an iceberg—there's more behind the wall than in front of it. A low quote often covers only the unit; the full scope includes vent pipe, gas line or electrical, framing, and the tile or stone that has to come off and go back on. Make every bidder price the whole job. If a dealer can't speak to the full scope with confidence, that's your signal to keep looking.

Ask three questions: Is it ugly? Is it drafty? Does it actually work? Most old fireplaces fail at least two. Beyond looks, an old unit leaks air around the damper year-round and—if it's gas with a standing pilot—quietly burns a couple hundred dollars a year. A modern replacement seals the wall, heats the room, and changes how the whole space gets used.

It genuinely can. I burned a pellet stove as my only heat source for years after a furnace died, and it kept the entire house warm. Pellets feed automatically from a hopper, so you get wood-heat economics with thermostat-style control. Two honest caveats: it needs weekly cleaning during the season, and most models need electricity to run—ask about battery backup if outages are a concern.

Fireplaces are like icebergs—bigger behind the wall than in front of it. Replacement means removing the surrounding tile or stone (the finish material laps onto the fireplace face), pulling the old unit, setting the new one in the same enclosure, and re-finishing the wall. A hearth professional can determine what's behind your wall without demolition during an in-home preview.
