I ran out of seasoned wood on Tuesday so I needed to find something to burn for a few more weeks and I didnt want to waste any of the stuff I have seasoning for the next 2 winters. I considered scroungeing pallets but I didnt want to deal with the hassle of busting them up. So yesterday I bit the bullet and bought a half ton of Enviblocks for $160. Thats supposed to be equal to a half cord of wood. I started off by burning a 3 pack that I stacked 2 side by side with a 4 inch space between them and 1 block on top bridgeing the 2 on the bottom. They ignited easily with some super cedar dust roled like a cigarette in a piece of newspaper that I put in the gap between the 2 bottom blocks. I got a little over 6 hours of burn time from them which is about the best I get from my smoke dragon. They definitely dont throw the same amount of heat as hardwood but overall they are not too bad. We burned 8 blocks since 4pm yesterday so I guess it will take 3 packs of 3 to heat my 1400 sq foot home for 24 hours. At that rate a half ton will last for 17 days of non stop burning. Pretty pricey if you used them all winter.
