Primarily a lurker here but wanted to see if any one else has tried Volunteer Wood Bricks yet, (broken link removed). Our only source of heat is a Castine on our "new" old house which we moved into last Summer. Last winter we used Envi 8's to supplement our "seasoned" wood, especially during the colder months and they worked well even though I have nothing else to compare it against. This year the plan was to purchase 3 tons of the Envi 8's to help with getting two years seasoned wood (not enough room for the three year plan), but our supplier ran short. They instead recommended these Volunteer Wood Bricks instead, nearly identical in size and they do not appear to ash up like the Envi 8's on the few times I have tested them this season.
