HOT BRICKS - are an efficient, all natural, pressed wood brick developed to replace traditional cord wood for home heating. We remove the bark and excess moisture from the wood fiber, which allows the heat created during burning to transfer directly into your home rather than going up your chimney. A well established HOT BRICK fire creates little visible smoke or creosote in your chimney and leaves less ash residue. HOT BRICKS burn Hotter and Cleaner!
