HOT BRICKS deliver more heat to your home because only kiln dry wood chips are used. The low-moisture content of the tightly compressed wood bricks creates a longer, hotter, more efficient fire. Unlike cordwood, HOT BRICKS do not waste heat evaporating the water trapped in the wood fiber. Instead, heat is immediately available to warm your home. HOT BRICKS are 100 percent natural, local, and renewable. The woodchips used to make HOT BRICKS come from within a 50-mile radius of the plant. Heating with HOT BRICKS is carbon neutral, making them the environmentally smart, sustainable choice for home heating.
