I'll bet there aren't any of the membership of a coal forum. I happen to know about them because of an old friend who owns Lyme Green Heat. Biomass and pellets are their forte.
I'll include a couple links. http://www.ahona.com/products-viadrus.html
(Morty Bailey, owner.) Lyme is the home base of Nichols Hardware from way back in the 60's, so coal WAS a big deal for some time in the area. Tarm, Eshland( now AHS) and a bunch of gasification rigs were my fire exposure to coal burning back in the early 60's....anyway the next generation has evolved the company into a national and international model. I know many will think you are an idiot and meant to say Buderus, but Viadrus is the real deal, and oil over there is around 7.60 a gallon........no smoke and mirrors here....enjoy.
Coal guys won't know much about 'this side of the pasture', but if you call Morty Bailey at Lyme Green Heat he will help you out. I've known him for 50 years, and you will learn to like him as well.
Where are you located?? Don't forget that Anthracite Coal is also a very viable, affordable safe and energy efficient fuel. Good luck on your research, those folks are the real deal.
The damned energy credits are tough to compete against......especially in Vermont; NH not so much. Please feel free to ask more questions here on the coal forum, because these folks are very supportive also.
Tell me more about the Biasi you have, please. A PM is fine if you don't want to address the entire forum.
