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.

Just picked up a ton of these pellets on 1/13. Burned 4 bags so far. They do give off great heat but the ash and soot is way higher than expected. The burn pot is also caked with ash and soot so needs to be cleaned more than once per day. I clean my Quadrafire CB 1200 weekly and the burn pot every other day, if not daily so stove cleanliness is no problem. Good pellet but not for $300 a ton.
Have used nothing but cubex in my Harmon stove since I bought it three years ago. Got high heat and low ash!! Thought they were great. Got a ton delivered in July 2012 and when I started burning them this past fall the heat output isn’t as high, they produced a lot of ash and have left many charred unburned pellets in the burn pot. The ash pan has to be emptied after every 4-5 bags, versus after 1/2 ton in the past. Cubex must have changed the formula. Too bad. I am now looking for a new pellet. Any suggestions?
We had exellent results with Cubex in 2012, our new order is AWFUL we have to clean the ash pan out 3 to 4 times per ton, last years pellets were 1 time per ton. Guess we will try something new. Can anyone suggest a new brand that burns cleaner.
I am on my sixth year with a pellet stove and have burned multiple brands over that time span. Decided to give Cubex a try this year after reading good reviews from previous years. These pellets are AWFUL and probably the worst I’ve ever burned. They put off minimal heat and are unbelievable dirty. My ash pan is caked with crusty sediment. I can’t believe I paid a premium for these pellets when others that are $50 less are ton are twice a good. Don’t waste your money on these.
finally have burned some cubex pellets and they burn real hot. 320 plus degrees from room blower no kidding.
They are cleaner burning as well. (less soot inside stove walls etc)
They do tend to clump a bit into a crust in the burn pot and have green “yes green” dust like particles in the crust.
Have noticed green flames at times as well. (and tonight too)
Great for the below 20 degree and lower nights.
