It leaves a lot of residue, crystallizes, clogs the chimney and air ducts, terrible quality, last year it had a different quality, something is not right this year, expensive for its quality only

it is a good pellet to get 20 bags to last you the year, for 1 ton I do not recommend it, it damages the interior of the boiler, it creates a crystal inside the boiler, the ash is average but it also creates an internal wall of 3 centimeters in the chimney like styrofoam that clogs it, I clean the chimney every year and I have never seen this before.

I have a pellet stove and I was using Bulgarian pellets with minimal residue. I bought 5 bags of this, 4.90 per bag from a well-known supermarket in northern Greece. The stove produces a lot of residue, it fills with ash, and as soon as you open the door, it goes everywhere, and it is slow to ignite the pellet at startup. Even though it is a Greek product from Nevrokopi that I would have liked, I will prefer the Bulgarian one again.
