I am considering getting an indoor wood boiler for my 2001 2800 sq. ft. home and putting it in the attached garage. I looked at most of the ones talked about in the forum e.g. tarm, ecoburn ect. I am leaning towards the biomax 40 primarily because not only is it a wood gasifier but it claims to burn just about anything e.g wood, wood chips, sawdust, any kind of pellets, corn and coal. Whats the deal. Seems like a no brainer. If I get that I can switch fuel types if needed. For example, there is a locale dealer who says he can deliver corn for $200. a ton or coal at $179.oo/ton. It may make loading the boiler less messy and more convenient; or I'm thinking of mixing fuels 50% wood 50% coal. Dealer says that is a good choice as the coal burns hotter and longer and the wood allows for easy reignition. Sound to good to be true. Any opinions?
