tractor supply eco bricks

I only tried TSC eco bricks so I dont have a comparison between brands. I laid the eco brick in the center of the stove on 2 inches of red hot coals(wood) and observed its burn ability. How long it lasted and whether it coaled. After it reaches the glowing coal stage the brick just falls apart.
I cannot comment on how much ash is produced from this as I did not have a full load of just eco bricks.
I dont know if I would feel confident using the bricks alone as a fuel source. I bought a three pack and if I used them it would only be to stretch a low supply of wood.

I use them, or rather the wife does. I have plenty of good hardwood on hand but I have to say that I like them for really quick heat on shoulder days. Here in SC it hasn't been cold yet so this morning I threw 3 on a bed of coals and packed cord wood around them. 4 hours later I came home and the Eco bricks were still present

Rebelduckman,

I'm using them this year, supplementing my supply of dry and not-so-dry wood. I place them in the firebox just as they come packed (wrapping removed). Key is they should be stacked tightly together, not having all surface area of each brick exposed. I then put a few not-so-fully seasoned splits on top. I then light them up using kindling along left & right sides of the stacked set of blocks. This will burn for some time, I can then add splits to the firebox as needed.
