I've been burning them too.
So far, I've burned about a ton of them.
I agree with you. Cleaner burning, no bugs and they stack so well.
Around here, a cord is $250-275 dumped in the yard.
The bio-bricks are $325/ton.
I'll use them again.
This is my first year with a pellet stove as well.
I'll use four or five tons of pellets this year.
I won't know until a get an oil delivery, but I've used probably 400 less gallons of oil so far, and I'll use no kerosene. Last year I used 250 gallons of kero.
The pellet stove will be paid for this year in oil savings alone.
I should have done this a decade ago.
