I have been using Enviro Bricks in my wood stove for three seasons now and am very happy. They are easy to transport and much less messy than hauling firewood through my house. There is minimal ash left over after burning them. I burned three pallets of them last season and when my chimney sweep came this year he couldn’t believe that there was less than 1/8 bucket of creosote in my chimney. They also take up much less storage space than firewood. Also the staff is extremely helpful and always a pleasure to deal with.
