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.

Where have these been all my life ! Boy talk about low ash hot burning beauties ,I will try others just to reaffirm what I already know they make the HEAT !
This is my first time burning cubex pellets in my Harman pb105 and I had really high hopes. NEVER AGAIN. These are producing minimal heat and my ash pan is full of charred and partially burned pellets. We’ve cleaned the stove every other day, turned pellet motor down and still bad. Any suggestions????
Been burning cubex in my Harman invinsible about 1/2 ton.pellets put out great heat, ash content is good,I have to empty ash pan every 2.5-3weeks burning 24/7,Screw that Oil man.Windows stay clean for quite a while too. for $280.ton can’t go wrong

1 ton of Cubex yielded 7.7lbs of ash = .385% ash
Bought a new Harmon stove just loveit..Wish I could find a cheaper supplier for full pallets of cubex pellets,The cost of them around here will make pellet stoves as expensive to run as an oil furnace soon..
