A pellet stove heats one area of a home by burning compressed wood pellets fed automatically from a hopper. A pellet boiler or furnace does the same for the whole house through hot water or ducts. Both are cleaner and more convenient than a traditional wood stove, and they can cut heating costs where the alternative is oil, propane or electric baseboards. The trade-offs are upfront cost, weekly fuel handling, regular cleaning, and a dependence on electricity and a steady pellet supply.
Key takeaways
- Pellet stoves typically cost about $3,500–$7,500 installed. Whole-home pellet boilers and furnaces often run $15,000–$30,000 or more.
- A home heated mainly with pellets may burn roughly 2–5 tonnes a season, depending on climate and house size.
- Modern certified units burn far cleaner than older wood stoves, but they still produce some particulate emissions.
- Pellet appliances need electricity for augers and fans, so plan for power outages.
- Pellets make the most sense in rural areas without natural gas and with a reliable local pellet supply.
How pellet heating works
Pellets are made from compressed sawdust and wood shavings, usually mill residues. They're dense, dry (typically under 10% moisture) and uniform, which allows a controlled, efficient burn.
- You fill a hopper with pellets, by hand from bags for a stove or by a bulk delivery into a storage bin for a boiler.
- An auger feeds pellets into a burn pot at a steady rate set by the thermostat.
- A combustion fan supplies air, and an igniter lights the fuel automatically.
- A heat exchanger transfers heat to room air (stove), water (boiler) or ducted air (furnace).
- Exhaust leaves through a vent, often a direct sidewall vent rather than a full chimney.
Stoves vs. boilers vs. furnaces
| Option | Heats | Approx. installed cost (CAD) | Fuel handling | Best for |
|---|---|---|---|---|
| Pellet stove | One zone / open area | $3,500–$7,500 | Bags, every 1–3 days in cold weather | Supplementing other heat, smaller homes |
| Pellet insert | One zone, uses existing fireplace | $4,000–$8,000 | Bags | Converting an inefficient fireplace |
| Pellet boiler | Whole home via hot water | $15,000–$30,000+ | Bulk bin, refilled a few times a year | Homes with hydronic heat, rural properties |
| Pellet furnace | Whole home via ducts | $10,000–$20,000 | Bags or bulk bin | Replacing oil or propane forced-air |
Costs are rough ranges and vary by region, venting and installer.
Fuel costs and use
Bagged pellets in Canada commonly sell for roughly $6–$10 per 18 kg (40 lb) bag, or around $330–$550 per tonne, with bulk delivery often cheaper per tonne. Prices vary by region and season.
As a rough guide:
- A pellet stove used as supplemental heat might burn 1–2 tonnes a winter.
- A pellet boiler heating a whole house in a cold region might burn 3–5 tonnes or more.
Compare that against your current fuel. In homes heating with oil, propane or baseboards, pellets often come out cheaper per unit of heat. Against natural gas or a cold-climate heat pump, the savings are usually smaller or disappear. Our whole-home energy guide can help you compare options in context.
The pros
- Renewable, often local fuel made from mill residues.
- Much cleaner than older wood stoves. Certified pellet appliances emit a fraction of the particulates of an uncertified stove.
- Automatic and thermostatic. No loading logs or tending a fire.
- High efficiency. Modern units often reach roughly 75–90% efficiency.
- Comforting radiant warmth and the look of a flame, for stoves.
- Fuel price stability compared with oil and propane in some markets.
The cons
- Electricity required. No power means no heat unless you have a backup generator or battery. In outage-prone areas, this matters.
- Regular cleaning. Burn pots need emptying every few days to weekly, ash pans weekly or so, and venting and heat exchangers need an annual professional cleaning.
- Fuel storage and handling. A season's bagged pellets takes up real space in a dry garage or basement. Lifting 18 kg bags isn't for everyone.
- Supply risk. Shortages have happened during cold snaps. Buying early helps.
- Some noise. Fans and augers make audible sounds.
- Emissions aren't zero. Pellets burn cleanly, but wood combustion still produces fine particulates, which matters in dense neighbourhoods and valleys prone to air inversions.
Choosing and installing wisely
- Buy certified equipment. Look for units certified to current CSA or U.S. EPA emission standards. Many rebate programs and insurers require it.
- Use a certified installer. In Canada, look for WETT-certified (Wood Energy Technology Transfer) professionals, or the provincial equivalent in Quebec. Insurers may ask for an installation inspection.
- Size properly. An oversized stove cycles inefficiently. Get a sense of your heat load first.
- Buy quality pellets. Look for certified grades with low ash content. Poor pellets mean more cleaning and lower efficiency.
- Plan for outages. A small battery backup or generator keeps a pellet stove running.

Pellets vs. heat pumps
Many Canadians now weigh pellets against cold-climate heat pumps. Heat pumps need no fuel deliveries, produce no local emissions and also provide cooling, but they rely entirely on the grid. Pellets offer high-heat output in deep cold and use a local renewable fuel. Some rural homes combine the two: a heat pump for most of the season and a pellet stove for the coldest days and outages. Our geothermal and heat pump hub and bioenergy overview cover both sides.
Frequently asked questions
How long does a bag of pellets last?
In a pellet stove on a moderate setting, roughly 12–24 hours. On high in very cold weather, it may go faster.
Can a pellet stove heat a whole house?
In a small or open-plan, well-insulated home, a single stove can cover most heating needs. Larger or divided homes usually need a whole-house pellet boiler or furnace, or another heat source for distant rooms.
Are wood pellets carbon neutral?
Not automatically. Pellets made from mill residues generally have a better climate profile than fuel from harvested whole trees, but the full picture is debated. See our post on whether burning wood is carbon neutral.
The bottom line
Pellet stoves and boilers bring automated, cleaner wood heat to Canadian homes, especially rural ones replacing oil, propane or electric resistance heat. Go in knowing the full cost: equipment, fuel, storage, cleaning and a backup plan for power outages. With certified equipment and a good fuel supply, pellets can be a solid part of a renewable heating mix.
