I have 21K square feet of manufacturing space heated by oil and 5K of office space heated by a heat pump. The costs are extreme. I'm meeting this afternoon with a tree service about dropping logs behind my building rather than hauling them to the dump or waiting for his firewood guy to come buy them. He wants to free-up space.I want free wood. My original purpose was to use an occasional drop to feed my insert at home. Now I'm thinking bigger. I envision a supplemental application that would minimize - not replace - my oil consumption. I'm brand new to the concept. Is there an application that will work with my existing conventional set up? I'm basically looking to be pointed in the right direction. Thanks in advance!
