I have a Wood Stove w-Catalytic made by vermont casting (not an old stove) I started burning biobricks last year..I found them convienent,but not cheaper than firewood..I also was told by the wood stove dealer that my stove is now out of warrenty because I used biobricks.. He told me the Catalytic was damaged from using biobricks..I can used 3 cord of wood to heat my home..It took 5 pallets of biobricks to do the same and now they are getting more expensive..I stopped using them and went back to wood..I get cord wood for $250 delivered,The biobricks were over $300+ per pallet..I don't think the biobrickis are a better alternative to wood..Biobricks not good for wood stoves? Do biobricks suck? I won't used them again..I didn't find any savings..Has anyone tried the larger wood compressed logs?
