Cubex
Premium 100% Hardwood Fuel
Produced by a Canadian hardwood flooring company, Cubex Wood Pellets are made from sawmill shavings, planer waste and chips from slow-grown deciduous woods like oak, maple, birch, beech, ash, cherry and black walnut. Because of that raw material and a careful manufacturing process, they deliver serious performance.
Typical specs: over 9,000 BTUs per pound and ash content under 0.4%. They’re dense, clean-burning and built for people who expect more out of their pellet fuel. You’ll find them available through dealers in New England states (including New Hampshire and Maine) and across parts of the Northeastern U.S.
In short: if you’re running a pellet stove tuned for hardwood fuel and you don’t mind doing a bit of extra cleaning for the payoff in heat and burn efficiency, Cubex is a strong pick.

Review of Cubex Wood Pellets
Cubex Wood Pellets — 2025 Review
Heading into the 2025 season, I’m pleased to say these remain one of my all-time favourite pellet fuels. The latest run has delivered impressively low ash levels — I still take a few minutes each morning to scrape the burn-pot and tidy the ash pan, but that minor routine is more than worth it for the performance I’m seeing.
The heat output continues to stand out: these pellets burn dense, hot and consistent, providing strong and steady warmth even in colder conditions. A slight uptick in required burn-pot attention is a small trade-off for the superior heat these deliver.
In short: the 2025 batch of Cubex pellets earns a solid thumbs-up. If you’re willing to do the occasional extra clean-up in exchange for high performance and low ash, these are a top-tier hardwood pellet option.
Cubex Wood Pellets are premium 100% hardwood heating pellets made from dense deciduous species like oak, maple, birch, beech, ash, cherry, and black walnut. They are known for high heat output (typically > 9,000 BTU per pound) and low ash content (under 0.4%), producing a clean, long-lasting burn ideal for pellet stoves and boilers. These pellets meet stringent quality criteria such as low fines and consistent pellet dimensions, making them a preferred option for those seeking efficient, high-energy residential heating fuel.

Even better this year
I have been using mainly Cubex for the past 6-8 years with mixed results with my Quadra Fire stove. So far impressed this year. Very low ash, no soot and good heat. Only negative is the price. Paid $8.15 per bag, which makes burning pellets almost not worth my effort. Needless to say, I didn’t buy as many as I usually do.

Better this year
I bought a few more pallets of Cubex this year and they burned much better than last years (2021) batch. I thought last years were on the dirty side (lots of ash). Saw a marked improvement with this years. Hopefully they stay on track.

Disaster absolute garbage
Absolute garbage. Burns awful if they catch. Need to do a complete stove clean after every bag. More I burned pellets go into my ash box then get burned. Will never buy again

Cubex is a total pellet disaster.
A total failure. Don’t by this crap! Firepot was totally clogged, overflowed with unburned granules. Tried on several occasions and it’s -30C outside. Granules would not burn with a bright flame but orange and black soot everywhere. It looks as if some additives were mixed in that they wanted to get rid of.
