How many bags of pellets do I need for winter?

A typical home in a cold climate (New England, Upper Midwest) uses 3-5 tons of wood pellets per heating season (October through April), which is 150-250 forty-pound bags. A moderately insulated 2,000-square-foot home using a pellet stove as the primary heat source typically burns 3-4 tons. Well-insulated homes or those using pellet stoves as supplemental heat use 1-2 tons. The best approach is to track your first season's usage carefully. Buy 2-3 tons to start and reorder as needed. Most dealers offer delivery and bulk pricing for 3+ ton orders. Are softwood pellets better than hardwood?

Are softwood pellets better than hardwood?

Softwood pellets often outperform hardwood pellets for pellet stove use. Softwood pellets produce more BTU per pound (because softwood resins have higher energy content), generate less ash (lower mineral content), and typically cost the same or less than hardwood pellets. The common myth that softwood burns dirtier (more creosote) applies to cordwood but NOT to pellets because pellets are dried to 5-7% moisture content before compression. Many pellet stove experts recommend softwood or blended pellets for the best combination of heat output, low ash, and value. How much does it cost to heat with pellets?

How much does it cost to heat with pellets?

A heating season typically costs $750-$1,750 in wood pellets for a primary heat source (3-5 tons at $250-$350 per ton). This is comparable to or slightly cheaper than heating oil and natural gas in many regions, and significantly cheaper than electric baseboard heating. Pellet prices vary by region and season. Buying in bulk (3+ tons) and ordering in spring or summer (off-season pricing) can save $20-$50 per ton. A pellet stove itself costs $1,500-$4,000 installed, so the payback period depends on what heating fuel you're replacing.

What Are Wood Pellets

Wood pellets are small cylinders (typically 1/4" diameter x 1" long) made from compressed sawdust, wood shavings, and other wood processing byproducts. The wood is dried, ground to a uniform size, and compressed under high pressure through a die. The compression generates heat that activates the natural lignin in the wood, binding the pellet without adhesives or chemicals.

Wood pellets are primarily used as fuel in pellet stoves and pellet boilers for residential and commercial heating. They burn more cleanly and efficiently than cordwood, produce minimal creosote, and can be automatically fed from a hopper, making pellet stoves convenient (load the hopper, set the thermostat, and the stove does the rest).

Premium vs Standard Pellets

Premium pellets: Less than 1% ash content by weight. Burns cleaner, produces less ash in the burn pot, and requires less frequent cleaning. Premium pellets are made from clean sawdust and wood fiber with no bark, which is the primary source of ash. Most homeowners should use premium pellets — the extra cost ($10-$30 more per ton) is offset by less cleaning and better stove performance.

Standard pellets: 1-3% ash content. Contains some bark, which increases ash production. Standard pellets cost less but produce more ash, requiring more frequent cleaning of the burn pot and ash pan. Some stoves are designed to handle higher-ash pellets with self-cleaning burn pots; check your stove's specifications.

Utility/industrial pellets: Above 3% ash. Used in commercial boilers and biomass power plants, not residential pellet stoves. Too much ash for most home stoves.

Hardwood vs Softwood Pellets

Hardwood pellets: Made from oak, maple, cherry, beech, and other hardwoods. Hardwood pellets tend to produce slightly more ash than softwood pellets because hardwoods have higher mineral content. However, hardwood pellets burn longer per pellet due to higher density. Hardwood pellets are the traditional choice in the eastern US where hardwood sawmill residuals are abundant.

Softwood pellets: Made from pine, spruce, fir, and other softwoods. Softwood pellets have higher BTU output per pound than hardwood pellets because softwoods contain more resin (which has a higher energy content). Softwood pellets also produce less ash. Many pellet stove experts consider softwood pellets the better fuel: higher BTU, lower ash, and slightly lower cost. The myth that softwood pellets cause creosote buildup (as with cordwood) doesn't apply to pellets because the wood is dried to 5-7% moisture before pelletizing.

Blended pellets: A mix of hardwood and softwood. Common and often the most cost-effective option. Performance falls between pure hardwood and pure softwood.

BTU Output

Wood pellets produce approximately 8,000-8,500 BTU per pound (premium pellets). A standard 40-pound bag contains approximately 320,000-340,000 BTU. A ton of pellets (50 bags) contains approximately 16-17 million BTU. For comparison, a cord of seasoned hardwood (oak) contains approximately 24 million BTU, but cordwood burns less efficiently (60-80% efficiency in a modern wood stove vs. 80-90% in a pellet stove). When adjusted for efficiency, a ton of pellets provides comparable heating to about one cord of hardwood.

How Much You Need

A typical New England home uses 3-5 tons of pellets per heating season (roughly October through April). This varies enormously based on home size, insulation quality, climate zone, and thermostat setting. At current prices of $250-$350 per ton (2024-2025), a season's heating costs $750-$1,750 in pellets. Pellet stoves work well as primary heat sources or as supplements to oil, gas, or electric heating systems.

Storage

Wood pellets must be kept dry. Moisture causes pellets to swell, crumble, and become unusable (they won't feed through the auger and produce excessive ash). Store pellets in a dry area: a garage, basement, shed, or covered area. Keep bags off the floor on pallets to prevent moisture wicking from concrete. Unopened bags in intact plastic wrap are moisture-resistant, but once opened, use the pellets within a few weeks or transfer to a sealed container.
