I'm using Enviro Wood Briquettes.
They're made in Berwick Me.
A ton is 84 packages @ 24 pounds each. There are 12 two-pound bricks in each package.
They light really easy, because I use Girl Scout Sticks
I'm using between one and two packages a day, now that it's really cold.
On weekend days I burn all day. I use about two packages.
During the week, I light a fire in the evening and burn through the night. I use about one package a day.
One of the advantages of the bio bricks is that you don't spend a lot of your btu's burning off moisture like you do with cord wood.
Cord wood may be cheaper, shit, it's free if I want to start cutting my woodlot, but I'm getting too damned old to be doing tree work.
I'll back the truck up to the bio brick pile and and then back the truck up to my wood room and save the tree work for the young bucks.
